ABSTRACT

The buildings sector is responsible for close to 40 per cent of global greenhouse gas emissions; 1 hence achieving significant improvements in energy productivity in this sector is a critical component of enabling nations to achieve long-term goals for greenhouse gas stabilization. Also, buildings are responsible for 12 per cent of global water use, 2 hence this chapter, focused mainly on energy, also presents strategies to reduce water requirements in buildings by at least 80 per cent. Water productivity strategies do not simply help reduce demand for potable water, but also yield significant energy savings through the reduced requirement to service a building with potable water. 3
