Over the last few years more stringent environmental laws (e.g. the German ìEnergie¨ein-sparverordnung ENEVî - Energy Performance of Buildings Directive) and soaring energy prices increased the need for the real estate industry to react. Therefore the Property Group at Queensland University of Technology in Australia and Nuertingen-Geislingen University in Germany carried out research in relation to sustainable housing construction and public awareness of ìgreenî residential property; this research resulted in two different surveys. One of surveys analyzed the situation in New Zealand, the other was focused on Germany. The purpose of this paper is to examine the buyer awareness and acceptance of environmental and energy efficiency measures in residential property markets. This study will provide a greater understanding of consumer behaviour in the residential property market in relation to green housing issues. This paper is a follow up to the previous paper, which was presented in 2009. Part of this research is to gain an understanding of the level of knowledge and importance of these issues to the house buyer and vendors to determine the importance of sustainable housing to the general public. This paper is based on a new survey from spring 2010. The paper compares this survey with data from the two empirical studies carried out by the authors in 2009.
