Managing the consumption and conservation of energy in buildings is the concern of both building managers and occupants and this use accounts for about half of UK energy consumption. The need to manage this has been given new emphasis by the introduction of the Climate Change Levy.

Energy Management in Buildings introduces students and energy managers to the principles of managing and conserving energy consumpton in buildings people use for work or leisure. Energy consumption is considered for the provision of space heating, hot water, supply ventilation and air conditioning. The author introduces the use of standard performance indicators and energy consumption yardsticks and discusses the use and application of degree days.

This second edition includes two new chapters on current regulations and environmental impact of building services. It closely follows recent bench marking published by CIBSE and the Defra energy efficiency Best Practice Programme and covers unit 18 in the new HND in building services engineering.

"...architects should benefit from some useful case studies and rules of thumb..."
