The entire design & construction industry is focused on increasing energy, water, and resource efficiency in building designs, however, new buildings represent a very small percentage of the full building portfolio. Over 95% of buildings that will be in operation 10 years from now are already built - the key to a national and cultural improvement in energy and water use is increased efficiencies within existing buildings. This course will explore ASHRAE 100, which is aimed directly at those improvements and standards required to improve resource efficiencies within existing building stock.

• Provide the requirements of ASHRAE 100, as it exists, and 100-2006, the proposed updated version.
• List and explain the meaning and application of concepts innate to the 100 Standard, such as AHJ, EUI, EEM, and IRR.
• Identify the main differences between source and site energy use, and the implications thereof.
• List and explain the various ASHRAE zones (1-8; a, b, and c).
