It summarises the essentials, rather than dealing with complex theory. It is aimed at busy managers. Chapters include: energy efficient buildings; building design - passive environmental controls; building design - active environmental controls; life cycle costing and net saving; conducting energy audits; the economics of 'green' building; useful addresses.
