Carbon Neutral Homes

Expected breakdown of electricity consumption

Bambrook, S., A. Sproul, and J. Copper. "Cost effectiveness of a carbon neutral house." ANZSES Solar 7 (2007).

Water Space Lighting Cooking Refrigeration Other heating heating/cooling appliances

PV is growing fast and getting cheaper

Quality of Construction• Aim to improve efficiency with uncontrolled

quality in construction does not make much sense. Building diagnostics shows significant difference with assumptions on thermal bridging, infiltration etc.

Occupant Behaviour

• Award winning 10 Star Josh’s House in Perth – a CRCLCL Laboratory

• The big issue is how best we can engage people in low carbon & energy efficient Living?
