The role of environmental sustainability has increased in the real estate sector. The adoption of sustainable principles, however, has been slowed by a lack of evidence relating to the financial benefits and uneven distribution of costs and benefits between owners (investors) and occupiers. This study identifies the drivers and benefits of environmentally sustainable buildings from the real estate investor's perspective. The research is based on a comprehensive literature review focusing on the previous research showing scientific evidence on the benefits of investing in environmentally sustainable buildings.
