Intended for practical application, this book provides a guide for reducing energy consumption in those buildings that were constructed when the cost of construction, not the cost of operation, was of primary concern. Now that the Golden Age of Energy is over, the heating, lighting, and ventilation systems of these buildings must be adapted to present and future economic circumstances.Landsberg and Stewart approach the problem of reducing energy consumption in these buildings by providing users of this book with solutions ranging from simple measures that cost nothing to complex modifications that must be given a cost-benefit analysis.The appendixes define energy basics for those who have little or no engineering background; evaluate alternative energy systems; and analyze the basic economic decisions of making changes in a building's energy consumption. The sample forms used for energy audits of buildings in New York State that can be adapted for use in other states and for private buildings are also included.About the Author: Dennis Landsberg is Vice President for Energy Analysis of W.
