The procurement route for building services encourage price not performance. Builders, developers and contractors are less concerned with performance, energy efficiency and life costing. Here are some simple examples of demand based control. Presence detection is a simple PIR type detectors in zones allow relaxed or occupied states. It widens the zero energy bands of control. CO monitoring modulates fresh air and exhaust air volumes of air handling plant. It also avoid over ventilation and energy waste. (12 pages)
