Engineering services present a significant cost in terms of the installation cost, the energy consumed and the maintenance, repair and upgrading of the systems. It is therefore important that construction professionals have a good understanding of the basics and applications of building services engineering. This thoroughly up-dated fourth edition of David Chadderton's text provides study materials in the fields of construction, architectural, surveying and energy engineering. In particular, the chapters on The Built Environment and Energy Economics benefit from the author's recent industrial work. Additional material, including further questions, interactive calculations, simple PowerPoint material and links to related websites, will be available on the author's website. David is a Chartered Professional Engineer with the Institution of Engineers Australia, a Chartered Building Services Engineer with the Engineering Council in the UK, through the Chartered Institution of Building Services Engineers, and a Member of the Australian Institute of Refrigeration, Air Conditioning and Heating. Since November 2001, David he has been Director of his own company, Eteq Pty Ltd. specialising in the designing and implementation of energy saving projects in commercial, health care, university and manufacturing buildings.
