Importance of the Energy Performance Certificate for landlords/vendors and for buyers: Germany

Conclusions in both countries environmental/energy

efficiency factors are still not the most important factor that buyers consider when purchasing a house

In New Zealand price and number of bedrooms are still the main determinants of house purchase, while in Germany the location to transport and schools are the main consideration in the purchase of a house.

Conclusion cont.

Both countries report a similar level of awareness and importance to the main environmental/energy efficiency measures in residential property, with buyers in both countries placing the highest importance on the correct aspect, ceiling insulation, heat pumps and double glazing.

Conclusion cont.

At this point in the ‘green housing” and “housing energy efficiency” development in residential property, for the majority of house buyers the importance of environmental factors appears to be an issue once the property is purchased rather than a consideration in the purchase decision

Conclusion cont.

The study results show that the most environmentally aware house purchaser is the higher income single or young couple buyer and the older high income retired buyer. All other demographics were more focused on price, house size and bedrooms rather than the ongoing cost of heating/cooling the property and the carbon footprint of the house.
