So, how did my old wooden house cope with the heat?
It’s not brilliant, but it’s also not unbearable.
I was at home most of Tuesday, and graphed the temperature rise. Inside temperature from the thermostat / Outside from the BOM Moorabbin Airport readings.
Unlike last time (2010), the overnight temperature had been a lot warmer, and thanks to this being just day one of a four-day heatwave, in the evening it didn’t drop off allowing the house to cool down.
The roof insulation that we have now made a little bit of a difference I think, but undoubtedly we saw the inside temperature slowly rise across the day. Better window protection is what’s really need to fight off the heat coming in, I suspect.
The additional fans we have make a real difference to comfort levels, even if they don’t seem to affect the temperature reported by the thermostat. Ceiling fans in two main rooms (plus a third in one of the bedrooms) plus portable fans help make it bearable.
Overnight Wednesday/Thursday the outside temperature dropped a bit more — down as low as 24 at midnight — allowing us to cool the house just a little from outside. As I write this, the thermostat reports 28 degrees. But to really cool the house will have to wait for the cool change on Friday afternoon.
And, in time, I’ll keep considering further house upgrades such as external blinds, window glazing, wall insulation, and the dreaded evaporative cooling and/or air-conditioning.
(By the way, if anybody had an appointment at the mobile Blood Bank in Bentleigh this week, they’ve cancelled the session due to the heat.)
Meanwhile, some interesting reading:
- Guardian Australia: Consumers who sweat it out in a heatwave subsidise those who turn on the air conditioning by $250 a year, research shows
— Stuff like this makes me ponder that it’s a little unfair that some areas likely to see power cuts caused by the stress put on by those with juice-hungry air-con, but which affects everybody — whether or not they have air-con, and whether or not they are offsetting their grid usage with solar. Surely in the age of smart meters, they could limit everybody to X kilowatts off the grid?
