Hot isn’t it? 5 easy tips to keep your house cooler next week

Every year around this time, Canberra gets its annual heat wave and the mercury hits around 40 degrees. Its something of a blessing in disguise to be able to go back to work, and the refuge of an air conditioned office only to dread going home to your sauna-like house. There are a few easy steps to make it more bearable.

Here’s Alexander Watson’s top 5 tips that you can do this weekend to keep your house cooler next week.

    1. Seal up gaps around windows, doors, exhaust fans and downlights. Stopping air leakage in summer keeps the warm air out for longer and helps refrigerated air conditioners work more effectively. Draft sealing tape and door attachments can be found at your hardware store relatively cheaply. Around $50

    2. Shut your home up during the day and open it up at night to flush out the heat. Unless you have evaporative cooling, remember to turn off your air conditioner once you start opening windows and doors. You cannot afford to cool the ambient temperature of Canberra with your reverse cycle system.

    3. Use shade sails and external blinds wherever possible, particularly on western facing walls and windows. Stopping the heat before it enters your home is much more effective that trying to deal with it once it has entered your home.

    4. Install roof ventilators to get rid of the hot air in your roof and take the pressure off your insulation. The cooler you can get your roof space the cooler your home will be. They’re easily installed if you’re a bit handy and can be picked up from your local hardware store for around $150 or get one installed through a company like us for $250.

    5. Arrange a thermal imaging analysis to identify exactly where heat is entering your home. Thermal imaging will pick up gaps in insulation, windows and any other areas that radiate excess heat. Ensuring that you have adequate ceiling and wall insulation without ANY gaps. Canberra homes should have R5 ceiling and at least R2 wall insulation. A 5% gap gives a 50% reduction in insulation performance! A quick look in your roof will tell you if it can be fixed. Look for gaps in insulation

    Alexander Watson specialises in energy efficiency audits and upgrades for existing buildings. They’re also locally owned and operated.

    This month only, Alexander Watson are offering free home energy assessments with thermal imaging (normally valued at $99).

    Thermal imaging cameras seek out hot spots caused by missing insulation and air leakage behind your home’s walls, ceilings, ducts and plumbing. This causes your home to leak heat while you waste money and energy on more heating and cooling.

Doesn’t need a source. Crap can mean worthless nonsense or unpleasant, so the statement is true one way or the other.

During last years heat wave due to a builders mistake we were left with a large east facing window with no protection other than an internal blind. A simple option was to wet some tin foil and stick to the glass and just keep the blind closed. The drop in temperature was significant and worth waiting out till the builder sorted out the problem.

Yes, OP, now that you have asked the question, I agree that it is indeed a little warm.

Yep its what I do and my solar panels still make around double what I use even with aircon on 24 hours a day lol Ive got my place around 21c.

Not as hot as 45 years ago…31/1/68 in fact…Canberra’s hottest January day (but close).

I can remember New Year’s Day 2004 it was around 44 degrees. And the day of the Black Saturday bushfires in Victoria in 2009 the Multicultural Festival was on here and I decided not to go because they were predicting 43.

I highly recommend using emergency space blankets in place of tin foil, they cover a much large area and stick more easily than tin foil.

They’re also great for privacy because they work like a 2 way mirror, allowing you to see out but appearing like a mirror from the outside.

Why, thanks, Alex, on behalf of readers who are at least 10 years old.

Here’s a tip – if you want customers, don’t start by treating them as though they all have sub-temperature IQs.

That’s funny, seeing as the highest temp recorded at Canberra Airport is just 42.2

How much would it cost? where does the waste heat go?

Yeah it’s slight daft advice, as it implies that your air conditioner would be having a cooling effect on the whole of Canberra. It won’t. Net effect on temperature will probably be positive, due the heat generated by the motor(s).

Best advice is the roof ventilation its the one thing I havnt done yet and it makes a big difference just have to work out which one. Passive one which is multiple tile vents lower and upper roof to create a convection current to suck out the heat. Or those whirly bird things. Or extraction fan with a sensor to come on say at 30c inside the roof.

All good advice. Ventilating the roof space is particularly worthwhile if you have poor ceiling insulation and/or metal roof. Tiles leak a fair bit of air plus they don’t conduct as much heat. Less worthwhile if you have R3,5 or better ceiling insulation as this reduces and delays movement of heat into room and with little thermal mass the ceiling and roof space cools pretty quick overnight.

Easiest way to ventilate roof space is with plenty of vents in soffits/underside of eaves and big vents at highpoints in all gables or simply a few big pipes rising up about a metre through roof near high points. Places that sell wood heaters can provide the gear. No need for fans, electricity, thermostats, etc – convection will do the job if there is enough vertical distance between inlet and outlet. Chicken wire and chimney hats to foil the birds and rain.

The lefty always have to get a dig in for this pet hate. Its either John Howard or Murdoch or Jones predictable lol. All successful guys hated by the left for that fact alone. Its so predictable these days that it really shows the immaturity and child like behaviour of the left.

I just picked one of the 500 heat related threads to point out that Canberra is currently the hottest capital city in Australia: http://www.bom.gov.au/

In a further update, it has dropped about 7 degrees!

Please let it rain.

Alan Jones has such a poor track record when it comes to reporting accurate facts, that he was ordered to employ a fact-checker before broadcasting anymore of his dimwitted gibberish. Since then, and despite the fact-checker, he’s been caught out yet again broadcasting his usual antifactual nonsense.

The whole, “it was once warmer at some place at a particular moment in time, therefore climate change is crap” used to to be funny, but it’s a joke that’s been done to death now.

Responsible adults don’t just compare two datapoints and pretend it tells them anything worthwhile. Reponsible adults realise that the largest possible dataset should be used by professionals in the field of statistics.

The kook blogs are always full of guest posts by kooks where they have looked at the sea level record at a particular spot in Brisbane and from that they make grand deductions.

Responsible adults will not rely on kooks blogging, instead we rely on science professionals, eg:
The trend for “warm nights” is very striking:
http://www.bom.gov.au/climate/change/index.shtml#tabs=Tracker&tracker=extremes-timeseries&tQgraph=TN90&tQave_yr=0
– nights are getting way warmer, with all this extra CO2 in the atmosphere.

Australia:
http://www.bom.gov.au/climate/change/index.shtml#tabs=Tracker&tracker=timeseries

Global:
http://www.bom.gov.au/climate/change/index.shtml#tabs=Tracker&tracker=global-timeseries

And what’s causing it?
Most reponsible adults are aware that CO2 is a greenhouse gas. Most responsible adult are aware that burning coal, etc, release CO2, and most responsible adults are aware that the amount of CO2 in our atmosphere has increased to levels not seen at any time in the history of our particular species.
http://upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Carbon_Dioxide_400kyr.png/380px-Carbon_Dioxide_400kyr.png

Now, should we really be changing our planet’s atmospheric composition to a new configuration that is entirely novel in our species’ evolutionary history? Who thinks that’s a good idea?

As for the amount of warming this will cause, nobody can be sure. Scientists have calculated that once we reach CO level of 580ppm, we will be on track for 3 degrees of warming. The uncertainty in their calculations means it could be 1.5 degree. Or, it could be 8 degrees. If it turns out they are being a bit too conservative with their estimations (as climate scientists have proven to have been over the last few decades) and if we actually get 8 degrees, we are %#$@ed. An ocean that heats up that much will suffer the sorts of problems that led to the Permian-Triassic extinction event, when 95% of marine species became extinct, and 70% of land species.
Ocean acidification is already happening, methane’s increasing,
