House Performance Snap Shot

Josh has been in the house for nearly six months now and reckons it’s an extremely comfortable place to live. Here’s a little snapshot of how the house is performing.

The following graphs show internal and outdoor temperatures across a period of one week in both winter and summer. Winter temperatures mainly sat within the ideal 18-25 degree C range. Last week, temperatures topped at 28 degrees C after several days of hot weather. With the ceiling fans on, player comfort on the couch watching the Ashes was more than satisfactory.

Electricity use is averaging 10.5 kWhrs a day. For a four person house, running three pumps, this is pretty good, but Josh is already identifying where he can make savings. Average daily solar power generation is 20 kWhrs per day, which means the house is producing nearly twice the amount of power as it uses. The house has been running on rainwater since July and the tanks have only just run out. The last water bill recorded a 0kL usage.
