11. Renewable Energy for Buildings

This chapter discusses the growing importance of integrating renewable energy technologies (RETs) into buildings, the range of technologies currently available, and what to consider during technology selection processes. A main section introduces the key principles relating to popular technologies, their functionality, and applicability; this includes: solar photovoltaics, solar thermal, heat pumps, biofuels, and small-scale wind. This chapter draws to a close by highlighting the issues concerning system design and the need for careful integration and management of RETs once installed; and for home owners and operators to understand the characteristics of the technology in their building. Learning outcomes: on successful completion of this chapter, readers will be able to: (1) Appreciate the growing importance of RETs and their application in the context of building integration; (2) Understand the principle mechanisms for their deployment in the built environment; (3) Gain insight into the range of technologies available and a deeper understanding of the popular technologies including: solar photovoltaics, solar thermal, heat pumps, biofuels, and small-scale wind; (4) Grasp the key concepts involved in selecting the most appropriate technology (mix) for a building; and (5) Know about the issues facing building owners and operators once a technology(s) has been installed.
