Sustainable Drainage Systems and Energy: Generation and Reduction

This chapter focuses on two areas associated with energy generation and use reduction. First it outlines the feasibility of integrating sustainable urban drainage systems (SuDS) and energy in one combined infrastructure that can reduce runoff but also generate energy to provide heating and cooling to buildings sustainably. Second, the chapter reviews the use of blue and green infrastructure in reducing energy demand for both heating and cooling of buildings. It also discusses ground source heat extraction and its specific integration into a SuDS pervious paving system to provide a combined system, which can address both flood resilience and provide a source of renewable energy (RE) at the building scale. Finally, the chapter details two case studies where combined pervious paving systems (PPS) and ground source heat extraction (GSHE) were installed in individual buildings and monitored to assess their ability to provide heat in domestic and office settings.
