Extractor fans, security screens and other passive cooling tricks

The key to passive cooling is ensuring the cool[er] evening/morning air gets into the house, while the hot day time air is kept out.


We often find that by about an hour after sunset the house is warmer inside than out. Our trick for getting the warm air out and the cool air in is: Extractor Fans. They are designed to remove steam and smells, but they are also brilliant for removing hot air.

 
We generally run them for a couple of hours at night, turn them off while we're all asleep (they are not designed to run for twelve hours at a time) then pop them on again in the morning around dawn if the house is still too warm. We also line up our pedestal fans so that they assist the overnight breeze (generally easterly in summer here).

If you've followed this blog even a little you would know that we also shade, shade, shade the house in summer. [If you're new to the blog, have a look at these posts on shading: 1 2 3 4 5 6 7 8] However, its two years since I last wrote about shading so here we go again with some more ideas we've been trying:

- pillows between glass and blinds in the lounge room window (above - NE window, guarded by Eva's scarecrow)


 - cardboard boxes between glass and blinds in the office window (NE window)


- large cardboard tray from a flat-pack furniture item, and a pile of polystyrene cooler boxes, to add insulation to the laundry door - nearly four square metres of glass that gets afternoon sun in summer (SW facing). It can only partially be shaded from the outside, given that it is a door so is not suitable for shading that can't easily be pushed aside.


- a mattress across the window in the children's bedroom (SE window).


- a cot mattress and more flat-pack boxes between glass and blinds in the bathroom (SE window)


- a former painting canvas between glass and blinds in the other bathroom (NE window). Neither bathroom has eaves, so shading these windows in other ways is particularly crucial.

All these shades are removed at night to let the night air in and the day's warmth out. This is possible because most of our windows have security screens. If we were not renters we would fit security screens to the two main living room areas immediately, as not being able to leave them wide open all night significantly hampers our overnight cooling.

After two weeks of lovely cool holiday in Victoria, we last week landed back into the peak of Perth summer. Its hot here! The temperature dipped below 20°C this morning, briefly, for the first time in six days, and maximums have been between 33°C and 40°C for a week, with a similar week forecast ahead. So far we have run our airconditioner for about five hours, on one night when it was not forecast to cool down and the air outside as full of bushfire smoke. Twice in the past ten days guests have commented on how cool our house feels, even noting that one room felt like the airconditioner was on (this at a time it was around 31°C outside).


Initial Time: All the additional shades above are daily measures that we only put up on the hottest days, and require about five minutes at each end of the day to put up and pull down. Extractor fans take seconds to flick on and off; pedestal fans take a minute or two to get into place where they are most effective for night times.

Initial Cost: Zero.

Ongoing time or cost commitment: As above.

Impact: An extractor fan uses around 25 Watts to run. We run three, for about five hours in total: 375Wh per night (about one third of a 'unit' in our system). 

Pedestal fans use around 40-50 Watts. We run four, all night, a total of around 1440-1800Wh. However, we also run them with the airconditioner if its on, so that we can direct the cool air up the passage and into the bedroom, due to the awkward placement of the airconditioner unit in our living/kitchen area.

Our airconditioner uses (roughly) between 1.5 and 2kWh (units of energy) per hour, depending on what temperature we set it to, what the temperature is outside, what the temperature is inside, etc. The night this week when we didn't open up the house, we ran the airconditioner for five hours (and pedestal fans for about twelve hours) to bring the inside temperature down to a bearable level ready for the next hot day - that is, to achieve the same effect that running fans and opening the house usually manages. Overnight cooling by airconditioner (and fans), then, uses about 9-12kWh per day, while overnight cooling by using the evening breeze assisted by fans uses around 1.8-2.2kWh.

Why we don't have a TV

We don't have a TV.

Why watch TV when you can watch the highlight of 2014 live, right across the road: 'Excavator knocking down HOUSE!'

As we never made a 'sustainability commitment' to not having one, I've not written about this. However, several times when I have presented about our sustainable living efforts it has emerged as a choice people are interested in, so here is my effort to share.

Disclaimer: Let me put right up front that this is not an attempt to judge anyone else's choices about television. If you have negotiated the issues I raise below in other ways, or the benefits of TV out-weight these issues for you, that's great. This is my attempt to explain my choices, not to have a go at yours.
 

Our family grew up without a TV* and, although I resented it many times as a kid, I am now grateful for that. [*We did have one in a box after I was seven, which came out in school holidays and for the Olympics]. When house-sharing, my flatmates often had one and I had patches of watching it. I learned that I am easily addicted to TV programs, especially ones with never-ending plot lines and endearing characters. I negotiated several times for the TV not to be in the main living area of our share-houses, once even buying a suitable wheeled table so it could be moved easily into the room of whoever wanted to watch it. Since Tyson and I have lived together we have never had a TV in the house. We watch a little Iview some evenings after the children are asleep, when we are too exhausted to do anything else (mostly British drama), at most perhaps five hours a week, more often one or two shows in a week (2 hours?). On very rare occasions Eva has been permitted to watch ABC kids TV shows on YouTube when she has been really sick. We also sit with them to watch and talk about clips on YouTube relating to things that interest them (most often excavators, excavators, chickens, giraffes, excavators).

I am not opposed to all TV watching forever, but I am choosing not to own one, and to limit our use of digital TV through the internet. It is a key strategy for us towards ensuring that as much as possible we create a home on our own values, not values absorbed by accident through a screen.


There are a whole range of reasons we don't have a TV. The summary version is: I believe TV primarily disconnects us from each other, sets up unrealistic and unhealthy social norms, and pushes us to be insatiable consumers. To explain a bit further...

How we shape our 'wants' 

I think the biggest problem of our unsustainable western lifestyle is that we want so much. One of the simplest ways to reduce our wanting is to cut out the voices of those suggesting more things for us to want. 

At the most obvious level, this is about not having advertising in our house (we also do not receive junk mail, read our news online so we don't have newspaper ads sitting around, and don't subscribe to the sort of magazines that are padded with ads). This makes a big difference. It was a change for Tyson when we moved in together, and over about the first year of sharing a predominantly ad-free house we both observed a noticeable reduction in the things he was wanting to obtain. Our children know very few brand names - in contrast to an American study that showed children entering primary school could identify on average 200 brand logos.


Of course it is possible to watch TV without advertisements (God bless the ABC and lets raise our voices to protest the budget cuts there!). However, in more subtle ways television as a medium, regardless of the advertisements, tempts us to want more. People are presented in an airbrushed manner (or presented as 'lacking', often by presenters who are clearly not 'lacking' in the same areas), creating a sense that the wonderful, earthy, fallible ordinariness of real lives is inadequate in some way. From the decor of fictional houses to the clothes of documentary presenters, the television world shows us a million things that we don't have, which we could potentially have, which could potentially redress that 'lack'. Yes, popping in to your neighbour's house and seeing their stuff can have the same effect, but it comes with a relationship, a possible story (including the reality of how little impact stuff has on happiness), and the limits of how many people we actually know to pop in on.


Focus of living areas

The way our houses are arranged both reflects and shapes the values we live by. Many Australian living rooms are arranged with seating almost in a line - perhaps a semicircle - focused on a television screen. If you are in a room like this, it can be quite hard to make good eye contact with everyone when having a conversation. The very way we place ourselves within the room reinforces a sense that we are spectators, passive recipients of someone else's agenda. I feel like this occurs even when the TV is turned off, because it remains the visual focus for how the furniture is set out.


In many ways television sets are placed within homes in the way that an altar might be placed within a home where religious observance is part of family life. It becomes a thing we worship. I find it a little obscene that it is considered the norm in Australian house design at present to include a 'home theatre' - a room virtually without windows, designed for people to not interact with each other or the outside world at all, but to be completely in relation to the digital world. This room is generally larger than the size of a whole house in many parts of the world, and uses far more energy and resources to create than those simple dwellings.

Our living room is a circle of couches and armchairs. There is also a piano, sort of at the side, and a toy shelf/play bench under the window, flanked by armchairs. I like that when we sit in this space, the focus is each other. When the children play they are central to our living space. Guests in our home have at times noted how relaxing they find it to be in a space without an omnipresent screen. (When we watch Iview or YouTube we use the office computer. The office, being also the guest bedroom, has a fold-out couch that can be used to watch the screen)

When we go on holidays, accommodation pretty much always provides a TV. We always cover it with a cloth, and sometimes move a couch in front of it.  


Objectification of people

The nature of television turns people into objects. We are watching; they are performing. We consume them. 

This is fairly obvious when, for example, an actor is performing a fictional role for our entertainment, and is not such a problem in that context (not so different from live theatre). However, we don't have the opportunity to see the actors leave by the stage door in their street clothes after the show, as ordinary and wonderful as us. When we do, it is in the context of celebrity-watching: trying to pretend we know these actors because we know something about them (however tenuous), or to pick holes in their presentation, to take evidence of ordinariness and hold it up as a fault, not a gift. Actors become semi-fictional realities that we seek to somehow have some ownership over.


However, objectification is more of a problem, in my opinion, when it relates to non-fiction content. News reporting is the most troubling for me. Other people's life crises become objects for me to watch. People being reported on cease to be people, cease to be 'like me', and become a Thing, a News Item, which I consume.

I believe that spending a great deal of time watching other people as objects, without any relationship with them, imprints on us a sense that people can be treated as objects; A sense that it is OK to think of others in a transactional way, rather than a relational way - where interactions always have a quality of what I give and what I get, rather than who and what we are building between us (with acknowledgement to William Cavanagh for getting me thinking about these things). Once we have made that step - and I think to at least some degree we have all made it - we can partition off some people, some 'objects', as less deserving of our compassion, or attention, or effort. Particularly, in the context of this blog, those among us who are most vulnerable as a result of our unsustainable lifestyle.


Gender representations

Somehow we have made it through five years of this blog without me beating this drum, but here goes:

The presentation of men and women on television is grossly imbalanced. The number of men, particular 'serious' men (in suits) far outweighs the number of 'serious' women, or women at all. Some excellent television drama includes strong female characters, but far more often women are presented within strongly gendered stereotypes. At worst, they are actively violated. More often, they are sexualised props for male-driven plots, with male heroes (sometimes with one token woman to make up the 'balance') and outcomes affirming male dominance. These are not the assumptions of a woman's role that I want my daughter to have imprinted into her (or my son, for that matter).


And men are poorly presented too: male characters, when not being macho aggressive strong-men winning situations by force and speed, are often goofy, a bit daft and easily led astray. Neither inspires my son to grow into a strong, thoughtful, compassionate, relational, confident man ready to take his place as an equal in the world with every other human.


Oversexualisation

Once you add together objectification and gender stereotyping it is no surprise that I have deep concerns about the sexualised manner in which both men and women are represented through television. The way a person looks is paramount to their TV appeal; the rules of what is 'appealing' are set by a narrow understanding of what is sexually attractive. Women are never seen without make-up (the way women actually arrive at every day of our lives, and the way we are known and loved by those we are really important to) or in clothes that might be described as 'shapeless': ie, not emphasising legs, hips and breasts. There is nothing wrong with dressing up and enjoying fitting a particular social norm; there is something deeply wrong with being made to feel unacceptable, to yourself or others, if you don't do it. I also have a problem with people's bodies, male or female, being an object for the gratification of people who don't know them, but watch them.


At the very pointy end of this, objectifying and over-sexualising women makes us vulnerable. Presenting men as either macho strong-men or a bit hopeless makes women vulnerable too. Both contribute to women being abused, and to men staying silent about it (or even encouraging it). 

Many of the things I hope for my daughter and my son are actively discouraged by the gender and body-image social norms that television is a big part of creating. I am helping them learn to navigate these cultural assumptions (yes, even at 5 and 2, and ever more so over the next twenty-odd years) but I am also inviting them to live their home-lives without those abnormal 'norms' constantly surrounding them.

Disempowering narratives

Most television content resolves problems within a viewing period. Perhaps it may take a whole season, but problems will be resolved. The overwhelming dominant narrative is that problems will be resolved by being the strongest/smartest/highest-tech or by straight out violence.


My understanding of the world is that actual, genuine change is slow, often hidden, and generally comes about by the sustained effect of countless tiny acts of love, kindness, bravery, generosity, hope, peace... most of which would not be remotely worthy of being 'viewed'. If you happen to be strong, smart, or equipped with marvels, the dominant narrative puts enormous and unrealistic pressure on you to provide results on behalf of all those ordinary people who are not so 'fortunate' - and it is little wonder that violence is so often the chosen approach. If you are not one of the 'fortunate' (I think it is a very mixed 'fortune'), this narrative either excuses you from having to contribute to our common good, or tempts you to feel hopeless about what you can actually achieve.

For those living within a narrative that is not heading for solution - chronic mental illness, for example, or the death of a loved one, or cyclical discrimination and poverty - the dominant narrative of problem-strength-solution has no place for you. Your grief is not permitted space. Your insights are not welcomed. Your ordinary daily struggles and triumphs are neither lamented nor celebrated - they (and you) are ignored. Perhaps that is its own blessing. It can also be degrading and disempowering.


Limiting children's creativity

I know there is much good children's television produced. However,  the nature of the medium largely makes the child a spectator while someone else does the creativity. Where good children's programming gives ideas for activities children can follow up, this tends to be a particular activity with a particular outcome.


We like to give our children materials and opportunities where they can invent their own outcomes, and often their own process as well. We like to read them books where there is plenty of room for their imagination to work, and the range of books available makes it pretty likely they won't be internalising quite the same mix of characters and stories as any one of their friends. It might be cute to have every girl at kindy playing at 'Elsa' but I am delighted that my daughter has instead played a hundred different characters of her own invention, including many that TV would have suggested to her were boys' roles.

 

Who's agenda?

Television programming can become a household's programming. Its 7pm, finish dinner so we can watch the news; I need to be home to catch the next episode of [insert favourite drama].

This is being somewhat addressed by digital TV-on-demand, but there is still a drive to watch it as it is aired (someone might spoil the ending for you on Facebook otherwise) or to catch it before it expires online. I have had dinner guests go home early because of a TV show they wanted to see; I have myself made choices about staying home to 'catch up' on a show online, and I don't like that.

The value systems implicit (or sometimes explicit) in both televised content and the medium itself are an agenda that I don't want to be run by. I feel TV needs very careful handling if we are to maintain our family agenda of love -  love for each other, love for our wider community, and love for our earth.


What do we support?

Its not so difficult to come up with a list of reasons I am against TV, but the more important question is: what I am for? Some of our priorities are: hospitality; building relationships; compassion; all people being equally valuable regardless of appearance, strength, colour, religion, ability, intelligence, disability, size, age, gender...; community; creative play; imagination; encouraging reading; open-ended play resources; getting into nature; non-violence; celebration of our ordinary bodies and ordinary lives; hope and possibility; genuine, wide-reaching gender equity; sustainable living; simplicity. On the whole, I believe owning a television does not advance these priorities and in many cases it is actually a hindrance to them.


So there you have it. Bless you for reading this far - I hope it is at least something interesting to think about.


What do we do instead? At gremlin hour, between 5pm and 6pm? When the kids wake up early on the weekend? The photos in this post are a few illustrations. We are fortunate that our work situation has meant we very rarely have only one adult in the house in the late afternoon, so one of us can cook and the other give the children 100% attention. Or the children help cook. Or we send them to jump on the trampoline, that magnificent child-minding device. They do get up early and they mostly find toys and activities without us. Mostly lego or craft, but I can see that when Eva learns to read it will be books, books, books.


Initial Time:  zero

Initial Cost: zero

Ongoing time or cost commitment: Not having a TV is both a time commitment, and a gift of time.

It is a time commitment, because without TV to mind the children they need more of our attention, patience and creativity.


It is a gift of time because I have available to me the hours I might otherwise spend watching TV to do all manner of other things. Things like writing this blog, being on the kindy parent committee, reading books, having really good conversations with my husband, hosting various groups in our house, playing Scrabble, writing in my journal... Sometimes I wonder how people who regularly watch TV fit anything else in, as my days and weeks are generally full to the brim without it.


Impact:

I believe I learned to be a more imaginative and creative person by not having a TV as a regular part of my childhood. I am hopeful to pass this gift on to our children.

A plethora of studies about the impact of television on child development suggest links between TV watching and aggression/violence, and long-term lower academic outcomes for children with high TV exposure. Here's a well-referenced article on potential impacts of TV on child development that goes into these and other issues in more detail. We are hopeful that our TV choices are having a positive impact on the sort of people our children are becoming, their views of the world and their ability to creatively navigate the challenges of their lives. 

 
Its not just about the children, though: I think limiting my adult TV viewing has a positive impact on the sort of person I am becoming. The people I admire and aspire to be like are people shaped by influences outside of the world of TV.

I think as a household we 'want' less than is considered 'normal' for our culture. There are whole cultural trends I genuinely know nothing about, or very little (loom bands? Frozen? Game of Thrones?). I know this will shift as we get deeper into school years, but Eva has not been in complete isolation - the last two years she has been part-time at kindergartens; she attended daycare; we are part of a church community; we have a wide network of friends and family, many of whom do not share our tentative approaches to certain cultural norms. We talk about things together, including advertising. We try to ensure birthdays and Christmas celebrations are not all about getting more stuff (see previous posts one two three four five).


Energy savings are not listed above as a reason we don't have a TV, because I have never been motivated in this choice by electricity use, but it is an energy saving to not operate a TV. The average Australian child in the 2-10 age bracket watches between 1 and 2 hours a day of TV (not including other screen activities), and more on weekends (the American Academy of Pediatrics in 2010 recommended no more than two hours TV a day, but various American studies estimate kids in the USA are watching closer to 30 hours a week of TV). Australian adults on average watch TV about two hours a day. So, if we were 'average' our household might watch about 25 hours of TV a week between us. The other 143 hours of the week nearly all Australian TVs are on standby, which also uses electricity. How much energy your TV uses depends on many variables: how much it is turned on, what sort of technology it is, how big the screen is, how bright you choose to have the settings. Here is more detail on TV energy use, including a TV-energy use calculator (scroll way down). Apparently, most TVs use between 80 and 400 watts. Older models can use up to 15% of this when on standby, but newer models often have efficient standby settings that draw as little as 1-3 watts. If we had a super-efficient 80-watt TV and watched the average 25 hours a week, we might use around 2kWhr (units) per week watching and another 143Whr in standby: a total of 111.5 kWhr per year (at current rates this would cost $34.55). If we had the 400-watt inefficient model, and allowed for 15% standby, 25-hour viewing weeks would result in an annual usage of 966.2 kWh (nearly half of which is standby usage) - a cost of $299.51, so not exactly 'free' entertainment for your children! Using these calculations, running a TV in Perth creates between 91.43 and 792.28 tonnes of carbon dioxide per year - more, if you have an inefficient model (plasmas are particularly bad) and watch more than average amounts of TV. Plus there are the issues of embodied energy I discussed recently in relation to washing machines.

Perhaps the greatest impact for me personally is that when I don't watch any TV I am happier. I would like to give this gift to my children.

Buy local for back-to-school supplies

Recently we went to visit Eva's school for next year and were given our 'booklist' for her first full-time school year ('Pre-Primary', in our system). We have committed to buying our school supplies locally, beginning with this list, and to ordering only what we actually need.


A 'booklist', for the uninitiated, is a list of stationery items that Eva is expected to bring with her on the first day of school, and does not actually include books. It is written with the sort of language you might find on a shopping docket (eg "Pencil Clrd Faber Castell Junior Tri') and the one we received added up to around $90. 


It also carried the company branding 'OfficeMax' and instructions for how to go to this company's website, enter the school name and password, click about three buttons (including credit card details) and have the whole list delivered to your door for a mere $8.95 postage (earlybird) or $18.95 (normal people who don't think about this until after Christmas).  

OfficeMax is an American-owned multinational corporation. Last year there were protests in South Australia when the company was awarded the contract to supply that State's education department's stationery needs, ousting a local cooperative of newsagents that had been supplying for 40 years, with an estimated 30% job loss within the cooperative as a result. 

 
We also have a fantastic local newsagent, McGhees, owned and run by local people. It might appear smaller than, say, an OfficeWorks store, but McGhees has a much wider range of products: because there is no corporate imperative to chuck away things no longer trendy, and shelves can carry one or two copies of ten or twenty different options, rather than fifty identical copies of the one or two items currently in favour.

Initial Time: Eva and I have started going for regular bike rides together, and this newsagent is a perfect distance and difficulty ride for her at present, so we incorporated our visit into a ride. It took me about five minutes talking to the assistant to give her a copy of our list (having crossed off the items we already have at home) and leave our details. They will call us when the order arrives and we will return to pick it up. If it was not part of our bike ride, the whole exercise may have meant half an hour (two fifteen minute trips) to arrange. But the whole point of buying local is that it is, well, local, so it is likely to be on your way to somewhere else rather than a special trip.


We also placed the order for another family attending the same pre-primary with whom we share buy-local values, so that family's time commitment was zero.
If you happen to live in the same area as us, McGhees has copies of the booklists for all local schools, so you don't even need to remember to take yours with you, and could place an order over the phone (this probably applies to your local newsagent wherever you are).

Initial Cost: McGhees did not have pricing yet for next year, but assured me they generally come close to OfficeMax's quoted prices. Plus there is the cost saving on delivery charges. 

Selecting only what we don't already have saved us about $10. The list might be hard to interpret, but its worth checking: do you really need another library bag? Another pencil case? Eraser? Ruler? Calculator? Lots of stationery items last a lot longer than one school year.

Ongoing time or cost commitment: We have committed to this for the duration of our school parent years: Half an hour a year for the next sixteen years. Eight hours between now and 2030. I reckon we can wear it, even if it blows out to (gasp) double that.

In future years, when I know more parents at the school, I hope to be able to place orders on behalf of a greater number of families, which may involve a little time organising a small collective effort.


Impact: Mega corporations are squeezing out local businesses everywhere. I recently read a fantastic article in The Monthly about the duopoly of Coles and Woolworths in Australia, which covers most areas of basic shopping, including stationery, and is squeezing both producers/suppliers and the small-business competition. An estimated 40% of all Australian retail spending goes to businesses owned by either Woolworths or Wesfarmers (Coles). With stationery, in addition to items available at actual Coles and Woolworths stores, it helps to remember that OfficeWorks, Target, K-Mart and Big W are also owned by the same two companies. Add to that the incredible dominance of foreign-owned OfficeMax, with its branded school-supplies lists, and it is amazing any local newsagents survive. Especially as sales of actual newspapers, the former mainstay of newsagents' trade, are dropping everywhere.

Back-to-school supplies are one of the most important sources of income for newsagents and other stationery suppliers. If we all choose the easy-click option of the 'chosen' supplier our school gives us, these wonderful local stores are in danger of being unviable.

As I described when I wrote about supporting local toy and book stores, buying local has huge social and economic benefits for our community. I happen to know that the proprietors are supporters of the drop-in centre up the road from them, which feeds and cares for the poor in our neighbourhood. The photos above and below show Eva participating in a free art activity that McGhees set up outside the store for the Council's annual Christmas Street Mall. These are just two concrete examples of the positive presence of a good local business.

Washing machine

When Tyson's sister moved overseas earlier this year, she gave us her washing machine. 


Our previous machine was my first ever white goods purchase, to serve a student house share, and at the time it was relatively water and energy efficient. More than ten years later it was valiantly continuing to serve, but was no longer the most efficient option available - and getting a bit small for a family. (How do such little people make such large piles of washing?!)

In addition to using a more efficient machine, we are also using its multiple function buttons to override its less efficient features. We continue to choose cold water every time, and only run the machine if it is full. We also now have control of the spin speed, and (except on very wet winter days) reduce it from the preset 1000rpm to the minimum 600rpm. It is also possible to end the wash completely before the spin cycle is complete, and I do this when I walk past during the spin.

Initial Time: an hour or two relocating the machine 30km across the suburbs and reinstalling.

Initial Cost: zero (big thanks to Auntie L!)

Ongoing time or cost commitment: Clothes takes a little longer to dry if not spun fiercely for the full cycle - but for at least six months of the year (more like nine) they still dry in a day on the outside clothesline in the sun. In wet months I keep the long spin for nappies and heavy items, but short/600rpm spin for other things.


Impact: The advertised energy and water 'stats' of the new machine - an Electrolux EWF10831 - are about the same as the old (310kWhr/yr warm; 130kWhr/yr cold; 68L per wash).

However, the new machine can take 8kg, rather than 5.5kg. This means that the total number of loads is reduced from 5-7 a week to 3-5 a week, and this is where the big saving comes: the machine is using the same amount of energy to wash 45% more washing. Energy ratings are calculated assuming one wash load per day. If we do four loads a week, we use around 177kWhr/yr. If we do six loads a week, we do around 265kWhr/yr. So, we are potentially saving 188kWhr per year, a reduction of 154kg of carbon dioxide. (That's without any alteration to the spin cycle - we could not figure a way to calculate that)

Our observation is that the new machine uses about 60% as much water per wash. We catch the water, so can make a pretty good guess at this. Previously we used around 85L per wash; now we are using around 50L. Allowing for the reduced number of loads, that's a reduction of around 16,000L per year.

Before you race out and replace your washing machine, however, its worth considering the embodied energy involved: the energy (and water) used to manufacture and transport the machine, including the raw materials used to make the machine. In addition to the obvious plastic and steel, washing machines use copper, silver, gold, palladium and platinum. Although mostly used in small quantities in the machine's electronics, extraction of these metals is considered to have high environmental impacts. Even spread over a ten-year working life, the embodied energy in the production of a washing machine has been estimated at around 16% of its total environmental impact, with its disposal after use another 10%. That is, only three-quarters of the 'footprint' of a washing machine is the energy it uses to wash for ten years - the rest is its manufacture and disposal. Another website suggests a twenty-year life span (optimistic!) and has the embodied energy calculated as 5,681,430,000 Joules (1,578kWhr).

Which leads me to: We have a fully functioning 5.5kg front-loader washing machine to give away. If you or someone you know is setting up house or still needing to transition away from a top-loader, and could help spread the embodied footprint of the old machine over a few more working years, please get in touch.

Update: We gave the old machine away using 'GiveIt' and it is now heading for a family in need.

Ethics in fundraising

I have made a commitment to work towards ethical options for fundraising in organisations I am involved with, and I'm delighted to share a current buy-local fundraising initiative I have arranged.


Last year, Eva's three-year-old kindergarten did a book fundraiser and bought all the books online. It was cheapest (they claimed). I suggested using our local independent specialist children's book store (Westbooks); the fundraising committee declined, despite the store offering a substantial bulk-order discount.

Later in the year toy catalogues were sent home for two online stores that give a percentage of sales to the kindergarten. I used my catalogue to browse for ideas then took it into our local independent toy store (Toys in the Park) and asked the manager, Jan, to order in a few items for me.


And of course there are the ubiquitous chocolate-sale fundraisers. Twice last year (two different groups) we were asked to sell Cadbury fundraiser chocolates. Both times I politely but firmly declined, on the grounds that I thought it was unethical to raise money to benefit my own children using products known to frequently be produced with the slave labour of other children. Both times I suggested using fair trade fundraising options (coffee or chocolate). One group got so far as to ensure their boxes included plain dairy milk blocks, the only Cadbury fundraising line that is certified Fairtrade, and noted this as a fair trade option in their promotional material.

This year, at Eva's four-year-old kindergarten (McDougall Park Community Kindergarten), I joined the kindy committee. The committee has opted for no fundraising chocolate drive at all. When the topic of online toy catalogues was raised I tentatively suggested approaching local businesses to see if they could offer us a similar deal and was given the go-ahead to at least try.

Both Toys in the Park and Westbooks agreed to assist with our kindy fundraising. I am even more pleased that our kindy committee decided to go with these offers and not send home the toy catalogues at all. (If you would like to participate, details of our fundraisers are at the bottom of this post).


Initial Time: Each time the issue comes around, there is a bit more research, a few emails and conversations, and for the buy-local initiative a bit of extra time in emailing and talking. Maybe an hour or two a couple of times a year?

Initial Cost: Zero. Buying local does not necessarily cost more, especially when the wider economic benefits to the local community are factored into the price. For example, some studies suggest local businesses spend twice as much of their income in the local community as chain-stores do (never mind online purchases, which don't have a local community at all!)

Ongoing time or cost commitment: As above.

Impact: Many, many sources show the social and economic benefits of shopping from local, independent stores: community well-being, healthy local economies, product diversity, better service, local employment, reduced environmental impact (transport costs etc). For books, buying local also supports the Australian publishing industry. For toys, buying from an independent generally means more thoughtfully chosen stock, less plastic rubbish and better quality items.


As for supporting fair trade, I will just refer you to the Fair Trade website, which says it comprehensively. In brief: my lifestyle should not be at the expense of the workers who provide it to me. For a clip on what might be in your chocolate if its not Fairtrade, see Heart of Chocolate.

If our thirty-one kindy families each spend $50 at both Westbooks and Toys in the Park during the promotional month (details below), that would be $3,100 spent locally instead of going into multinational pockets, and $465 worth of books and toys for a fantastic local community kindergarten. Some families are planning their whole Christmas shop to line up with our fundraiser; others won't participate at all; this is a guesstimate! I'll try to post in the comments later in the year what the actual numbers are.

Even when my actions didn't change the fundraising that was undertaken, raising the issue was an eye-opener for most of the people involved in the committees behind the decisions. On chocolate, in particular, most of those involved in choosing to sell chocolates had no idea child slavery was an issue in chocolate production and were grateful for having been informed. I am hopeful this might influence their future choices.

Get involved:

In October, shop at Toys in the Park (403 Albany Hwy Vic Park 08 9470 3981 - featured in all the pics on this post) either in-store or online and mention McDougall Park Community Kindergarten and 10% of your sale price will be put towards a credit account for the kindy to purchase resources. If you order online, send an email through the contact form to ensure the kindy benefits from your purchase.

In November, try it at Westbooks for kindy to get 20% of the sale credited (although you may need an appropriate bit of paper in your hand - I am still working on details with the store, who are currently moving premises - contact me in late October if you would like more info)

Goodbye phone books

Phone books make great door stops.


They also contain lots of contact details for people I don't know and businesses I will never use. So recently we opted out of receiving any for the next five years.

Probably in five years time I will get myself an updated business & government directory (White Pages) and then cancel for another period. I doubt I will ever opt back in to the Yellow Pages.

Initial Time: Five minutes to go online and opt out. Go to https://www.directoryselect.com.au/action/home

Initial Cost: zero

Ongoing time or cost commitment: We do use our hard-copy phone books occasionally, and it generally takes a little longer to get the Yellow or White pages up on Tyson's phone than to flip open the book (or longer again if we have to fire up an actual computer) but its a few extra minutes a year. Updating the book every five years instead of every year would be enough to keep it useful.

Impact: Sensis, who print phone books for Australia, is 'proudly carbon neutral', encourages recycling and from what I could find prints within Australia, so it is doing its best. Nevertheless, millions of phone books are printed and delivered every year that are rarely or never used, and however you off-set it or recycle it, that is a lot of unnecessary paper. When the company changed from opt-out to opt-in for residential phone directories a couple of years back only 2% of suburban households requested to still receive books, suggesting a lot of people had little use for the ones they previously had delivered every year. I couldn't find a figure for how many books are currently printed but from various data about percentages in particular areas my estimate is around 15 million phone books in Australia each year. At 800-1000g each, that's approximately 13,500 tonnes of paper. If only 2% are actually wanted or used, that could be reduced to 270 tonnes. Even if I have wildly over estimated, it is still a lot of paper that could be avoided. And that is just the product itself - there are also factors like resources used to run the printing factories, wrap books in plastic, transport them and dispose of them at the end of each year.

(For those not in Australia: every household in this country until recently was supplied for free every year with paper phone directories - some years four fat volumes - as part of the main telephone provider's legal obligations to provide a directory service. White Pages books are alphabetical listings of all registered land-line phone numbers; Yellow Pages are commercial directories that businesses pay to be included in. In the four largest cities, which together account for over half the nation's population, the 'residential' volume is now opt-in, and the others have been stream-lined, but two volumes are generally still delivered)

Hand warmers and hot water bottle

When working from our home office I have committed to, wherever possible, warming myself rather than warming all the air around me.


The office is often the coldest room in the house and I have spent a lot of time there this winter. Besides wearing warm clothes (including ugg boots) and often wrapping myself in a blanket, I also started to put a hot water bottle under my feet at the desk. I am amazed at how successful this is at keeping me warm. One hot water bottle, wrapped in a towel, lasts a whole work day.


I also purchased hand warmers from our good friend Megan of Granny Funk Crochet.


Sometimes I will also warm a heat pack in the microwave and sit it in my lap for a while in the morning when it is most cold, or if I am working at night. With these aids, I virtually never turn a heater on for the office. I think better with cool air on my face, so these are both sustainability and productivity measures.

Initial Time: Boiling a full kettle for a hot water bottle takes about 5 minutes. Purchasing hand warmers involved some emails with Megan and a few days to wait for delivery.

Initial Cost: Extra hot water bottles purchased recently cost $12.95 each. They now have covers made out of cut up old jumpers, and I also wrap my office foot-warmer one in an old towel - no cost. Hand warmers were $30. Or you could sign up for one of the Granny Funk crochet classes and learn to make them yourself.

Ongoing time or cost commitment: Five minutes for the hot water bottle each time. A cost saving due to reducing the amount of energy used for heating (see below).

Impact: Boiling a full kettle of water (1.75L) when the temperature is 10°C uses approximately 661.5kJ of energy, or 0.184kWh ('units' in our system) - 184Wh, or about the same as leaving a 60 Watt light bulb on for three hours. (see my previous kettle post for the formulas). Microwaving a heat pack (wheat bag) uses around 42Wh to give warmth for about two hours.

When all attempts to warm myself with body heat, clothing and a hot water bottle fail, I use an electric oil-fin heater. This is a 1000W device, but as I would never run it flat out and it heats a confined space, the actual use is less than this. If I were to run it for nine hours of work day, it would use approximately 3.5kWh.

Using one boiled kettle instead of the oil fin heater for a day of warmth saves over 3kWh (units) a day, around 2.5kg of carbon dioxide every winter work day. 

Running the reverse cycle air-conditioner in our living area to warm enough house to reach the office is hard to measure, but the office is the far corner of the house from the aircon. A fairly conservative guess would be 5-6kWh per day to use the reverse cycle to heat the office, which is why we don't do that.

Loft bed

June was Month of the Loft Bed.


If children's excitement could be linked to a battery, we would have been running off-grid all month. 


Tyson built this bed using mostly recycled materials found on verge collection. We gathered up an almost-complete single and queen bed frame. Some of the timber was too deteriorated to use. Other bits were joined together to make stronger posts and the dents and damage marks puttied away.


The sides from the queen bed were added to the single bed. Some additional new timber was also needed.

 

Tyson worked away at it for weeks, with some help and tool-loaning from his dad. As after five dry months it rained here nearly all of May, we re-purposed the carport (our only covered outdoor area) as a workspace.


Finally the bed moved inside, heralded with unbounded joy by its new occupant. 


And by her small accomplice, who learned to climb the ladder in about ten seconds flat.


This is a step for sustainable living on account of the recycled materials, but also as a way to use our existing space. It can be easy to see an overcrowded room and think it needs to be bigger. Or to anticipate two children big enough for their own big beds (not quite yet but coming soon) and assume they need two rooms. 


The loft bed has transformed a fairly ordinary room into a fantastic play space, with the under-bed area great for cubbies (with their own light!) and the increased floor space inviting more play in general. The lower bed (also an old verge-collection find) is not physically attached to the loft bed, to allow maximum flexibility as needs change. The ladder can also be easily moved, including going over the end if necessary.


Initial Time: Oh well. Lets just say a lot. Tyson has been full-time home dad the past few months and this was his main project, in between parenting, for weeks. Plus there were months of dreaming, thinking, planning, carefully watching the verge, bringing materials home, hiding a single bed frame under another single bed for six months while waiting for more, sketches, measurements...

Initial Cost: $200 for timber and assorted things like sand paper, screws, wood putty, etc. Especially for The Ladder (which is arguably the best bit of it all).


Ongoing time or cost commitment: Zero. While we could possibly have picked up a second-hand loft bed for around $200 on Gumtree etc, new beds like this cost $800-$1200, so it was a considerable saving.

Impact: Two beds saved from land fill, and equivalent timber, factory overheads, chemicals, transport etc saved from being made into a bed for us. The timber we bought was plantation pine, while many manufactured beds use rainforest timbers. One modest size bedroom has been made to feel bigger. And the joy... 

I'm also posting about it because I'm so darn proud of Tyson's efforts. And because Eva wants photos on the blog to show the bed to her beloved kindy teacher.

PS: I've added an extra photo of our boy playing in the winter sun to last month's post. For those of you in it for the photos.
