ABSTRACT
Most green buildings pay when measured by strictly financial criteria in that the extra construction costs of sustainable design are retrieved through reduced running costs in the first eight to ten years. In some particularly well-designed buildings there may be no additional building cost, as in the Leeds City Park (Chapter 10), or the saving in energy bills may pay for the green measures in less than five years, as in the Queen’s Building at Anglia Polytechnic University (Chapter 12). Poor green design is where the additional construction costs are never recovered through reduced heating, lighting or ventilation bills, or increased productivity as a result of higher comfort levels.
