Sustainable homes national value case

Ralph Chapman, Wayne Sharman.

This report quantitatively assesses the National Value Case for a range of innovations related to the efficient and sustainable use of the country’s resources in housing – Beacon’s High Standard of Sustainability (HSS) for housing. The National Value Case is evaluated with respect to four types of HSS benefits: private economic benefits that accrue to households, environmental benefits, social and other private benefits, and national resource use efficiency.

The results show that the strongest National Value Cases are for compact fluorescent lighting and instant gas hot water systems. Pellet burners and heat pumps for space heating, water metering and a package of three water saving measures also have a reasonably solid national value case. Retrofit insulation performs less well, and heat pump hot water systems have only a weak National Value Case.
