We're just not built for winter in Canberra

It was July when I made the call enquiring about working in Canberra. The response was a little bemused, even incredulous.

For him, it was the depths of winter, while I was up north, where the temperatures were still in the 20s.

We came anyway, of course, and that was nearly 30 years ago. But when, like this week, the air turns frigid, the light fades, and things turn literally SAD, the doubts return.

It will pass, like always.

But it does remind me how staying warm in Canberra has been a challenging, expensive task, whether it be forests of firewood, fields of gas, or substations worth of electricity.

Friends who endured sub-zero winters in Europe told us they had never been colder than in the average Canberra house.

Nor paid so much to still feel cold.

Especially when the utility estimates your bill or when it does actually send out someone to the property they misread the meter.

This is why we looked forward to a new townhouse with reverse-cycle air conditioning, insulation, double glazing, and a high EER, which is even higher now with shutters and insulating curtains.

Yes, we did everything right. So why is it still cold?

I swear the air-con is going to be blowing non-stop till September.

What happened to the BOM’s “warmer than average” forecast? Maybe this is as bad as it gets. I live in hope.

OK, our expectations were probably a little unrealistic, and we didn’t account for the sun going missing in action for most of the day. And the leakage. That’s where the cold air seeps in and the warm air leaks out.

It’s the enemy of energy efficiency and a common denominator in most Australian buildings.

When you see the light sneaking through the garage and front doors, you know where the icy air creeping up the stairs to the living room is coming from.

But really, if the frost is crackling outside, the place just becomes a cooler.

We will find a solution beyond thermals, but probably not in this cost-of-living crisis winter of discontent.

That’s the problem. Energy efficiency is great, but it comes with upfront costs that have to be recouped down the track.

Is it better than the 50-something-year-old house we left after 16 years, where using the gas heating was like putting a match to a pile of money?

Absolutely. But it shows the extent of the challenge Canberrans face when even new housing still can’t be as efficient as it could be.

Design and aspect are everything, and the Passivhaus people have a lot to teach us about building for climate and leakage.

In my dreams, though, we have a northern bolthole by the sea to winter in and a cool mountain retreat in the summer.

But seriously, spare a thought for those living in ice boxes who can’t afford to use the heating, don’t have any heating, or worse, are without a roof over their head. Take a look in the linen cupboard or the garage for the spare woollen blankets or a heater no longer needed. There are some grateful strangers out there who would find your unused items a good home.

This Thursday (20 June), Canberra’s leaders will bed down for the night in the chill for the annual Vinnies CEO Sleepout to fight homelessness, a cause worth supporting.

The good news is that the next day is the solstice, and Sol starts his journey back into our courtyard.

Your reverse cycle a/c is probably operating most of the time in defrost mode. If only the ACT Government wasn’t trying to make heating the house more expensive by banning gas heaters, you could run a gas heater that doesn’t have to keep stopping to defrost the condenser coils (Federal Gov’t tells me to install a gas heater to reduce heating costs)

Consider yourself lucky that the original choice of Dalgety in 1904 was overturned in 1908.
Unfortunately it didn’t go far enough. It could have been Yass, on the main MEL-SYD route and we might have had high-speed rail decades ago.
Lake George was considered as a water-city like Geneva, unknowing how unreliable is the lake level.

What’s the point of this article? Get a heater. I lived in one of original Uriarra forestry homes, circa 1982. It had an outside toilet and an inside fireplace. I survived.

Some people cannot afford efficient and effective heaters.

We live in an East-West house with no northerly windows.
Our solar hot-water panel is shaded by the neighbouring “protected” gum tree, meaning additional cost to heat our hot-water.

(I should also say that that tree fills our respective gutters valleys with leaves, which can not be easily reached – the government refused to allow the removal of the tree.).

The government has introduced legislation requiring landlords to upgrade their properties to meet higher energy standards. In the meantime, I expect many landlords now live in houses that are colder than that occupied by their tenants. (I’m not a landlord).

There is also a government funded program, where those renting can have the property the live in, inspected and advice received about what they can do to reduce their energy consumption.
This scheme does not exist for owner-occupiers.

Sadly, those of us with older homes, that aren’t on slabs and don’t have good solar orientation etc, our options are limited. Yes we rug up etc. We have also topped up the insulation, but short of spending many tens of thousands on double-glazing etc, we are destined to freeze our butts off over winter.

The other issue of course is that unlike things like solar panels that might pay for themselves within a reasonable time, with the payback period to retrofit double-glazing etc, it doesn’t make any financial sense. Frankly, we won’t live long enough.

Unpopular opinion: Canberra houses aren’t actually that bad. Try NZ for a poorly built house that you’ll freeze in

We have a double brick house built in the early seventies no double-glazing heated by ducted air conditioning which is very efficient and fast heating. The inside temperate never goes below 15. Only use heating as the sun goes down and switch off at bedtime.

1. Try buying warm clothes in Canberra. It’s almost impossible. I went into the menswear department of a well-known department store in late autumn and found myself looking at piles of cutesy cotton short shorts and what was advertised as a stretch slimline pant, suitable for North Koreans under twenty five.
2. We live in a twenty year old townhouse. We have a reverse cycle heat pump fed by a 4.6 Kw solar system. We now insulate our windows against heat getting in in summer and heat getting out in winter: this resulted in last year’s electricity bill being about forty percent lower than the previous one. Did we spent thousands on double glazing, remotely-controlled external blinds or honeycomb blinds? No we did not. We use homemade shade cloth panels in summer and – shock, horror – bubble wrap in winter. It works beautifully, and we’ve suggested our methods to people we know who haven’t two cents to rub together and who live in rented, poorly insulated houses resulting in huge electricity bills, one family spending more in a month than we do in a year. Have they followed our advice? Oh no, no, no. It’s too cheap. Tin foil hat stuff.

“What happened to the BOM’s “warmer than average” forecast? “

Oh dear. I hope this wasn’t a climate change fanatic hoping for global warming

In two story houses ceiling fan set to winter are great at dispersing heat and keeping heat from heading up stairs leaving the ground floor cold. Rarely mentioned but really works and is cheap.

I suspect that Canberra houses aren’t built to European standards due to the fact that it doesn’t really get all that cold here and the winter doesn’t really last all that long. Sure, you might be a bit uncomfortable but you probably won’t die if you have a decent blanket or two and a jumper you can put on. That being said, I never lived in an energy efficient home until I was an adult and the difference between that and the ex-govy houses I grew up in is incredible.

Have you tried wearing more clothes?

We pay on average $2k per year on energy to heat, cook and wash in our 1980s brick veneer on a wooden floor. Keep the house at 25 in summer and 20-22 in winter although down to 19 at night in winter.
We double glazed everything, insulated the walls and underfloor to compliment the ceiling insulation. Heatpump hot water with 6.6kW solar and a battery. Toasty warm.

Rubbish! We live in a 7star home,the place gets to hot in winter,A/C runs on or around 19-20 Celsius, if it gets extremely cold bump it up to 22.Summer, we have no issues @ all.All about how a house is constructed.
