Abstract
The existing Australian building stock is responsible for around one quarter of our total greenhouse gas (GhG) emissions, and it is being replaced at a very slow rate. We urgently need to retrofit these buildings to reduce our GhG emissions to meet Australia’s expectations and international obligations. This paper illustrates a method of finding practical refurbishment options to reduce GhG emissions in a brick veneer residential project home by employing best practice passive solar house strategies. The method uses the second generation residential energy rating software, AccuRate to gauge the effectiveness of each option, and then estimates the cost of those options, including current government rebates. The paper also considers the lessons learnt from the design of the solar photovoltaic system, and considers the advantages of using GreenPower. The case study uses various criteria to rank the strategy results e.g. the star rating (the ceiling R4 insulation increase was two points); the savings of the energy required for comfort; the cost; and the extent of carbon reductions. The case study also shows the dramatic impact of the solar photovoltaic system
