ABSTRACT
In the United Kingdom (UK), the Utilities Act (2000) requires power suppliers to provide some electricity from renewables, starting at 3" in 2003 and rising to 15" by 2015. In a similar way to the European Union Emission Trading Scheme (EU ETS), generating companies receive and can trade Renewables Obligation Certificates (ROCs) for the qualifying electricity they generate. On-site renewable energy sources are taken into account and there are limits on design flexibility to discourage inappropriate trade-offs such as buildings with poor insulation standards offset by renewable energy systems. This chapter focuses on building-integrated options rather than large-scale utility solutions such as wind farms, which are addressed separately, and provides an analysis of where they may be best installed. It discusses the technology options and applications: wind generators, building integrated photovoltaics, ground source heat pumps, solar water heating, biomass boilers, and biomass combined heat & power.
