Ecologically Sustainable Development (ESD)
An ESD Assessment encompasses all design aspects of a building in terms of its energy, water and waste efficiency. The scope of the ESD assessment may be limited to one or more of these design aspects. An ESD assessment is typically applied to a refurbishment or new building design and will consider both passive and active design elements.
Passive elements are non-consuming elements of a building and maximise its energy, water or waste efficiency. Key areas of energy passive design include orientation, zoning, thermal mass, glazing, insulation and ventilation. Key areas of passive water design elements include rain water harvesting and or water recycling systems and selection of efficient faucets, showerheads and toilets.
Active elements are energy or water consuming elements that are incorporated in the building design. Key elements include air conditioning systems, lighting systems and pumping requirements.
