With a focus on how to apply proven Green Building Technology to the design and energy use of a building, the ASHRAE GreenGuide provides mechanical engineers, architects, and construction engineers hand's-on, needed tips on everything from site location to the latest in energy-saving HVAC Systems. This new edition will carry that invaluable practical help forward with the latest on LEED (Leadership on Energy and Environmental Design) guidance as promulgated by the U.S. Green Buildings Council and will offer the latest in sustainable materials and systems specifications. Moreover, the new edition will be better organized around the actual construction project sequence from important Green decisions that must be made at the pre-design and programmatic phases on through the actual construction documents and specifications and eventual Post-occupancy. It will also be greatly enhanced with new Green Tips, including an expanded version of the Green Tip that focuses on specific building types. Dual units have been provided as well as more international HVAC engineering representation in the content authorship. No other guide of this kind offers the authority and accuracy on green HVAC and building technologies like this book.
