I know some people still visit this blog, but we have been enjoying the house and getting out and about rather than doing jobs. But things are still happening. The sunroom glazing was installed in December by James Brewer and his mate- it really works! I love sitting out there when the sun is shining and basking.
We are also getting energy results that better reflect the design intent. One day I will update the Passivhaus Planning Package to see what that predicts. Meanwhile, we our annual gas usage is 57 kWh/m2a, compared with 171.5 kWh/m2a before we started, a reduction of 67%. (That high bar on the left was December 2011, when we had done most of the work, but not finished the insulation or airtightness. There is more air sealing to do!)
My own goal was to reduce by 80% - we could do better if we had a solar hot water collector installed. That may come when the Renewable Heating tariff is introduced and we actually shell out for the collector. The red line represents 120kWh/m2a, another Passivhaus target. We are doing well in that regard.
