Now residing in a 30 year old town unit we have been gradually upgrading our power supply, improving energy efficiency and other aspects to make it sustainable. Since our purchase two and a half years ago we have had the roof reconditioned and painted with reflective paint, had 4 Kw of photovoltaics installed, changed the old heater for a reverse cycle air conditioner and installed a heat pump.
The weather predictions for the summer of 2015/16 have been looking ominous. The earth is already on track for the hottest year since records began. As well a super strong El Nino threatens. With previous heat waves in mind I decided it was time to top up our roof insulation. The original insulation was still in place but thin. Typically these places were built to the minimum required building standards.
One phone call, two quick visits from the contractor, a quote, an hour or two installing bats and the job’s done. Hopefully this will reduce the load on our reverse cycle airconditioner this summer and help keep us cool. As there is no insulation in the north-west facing walls we are now looking for ways to provide summer shade for them. Unlike modern buildings the eaves are substantial and provide wall shade except for late summer afternoons. With this in mind the gardening books have come out and we are searching for some suitable, non-invasive climbers or creepers.
