1999 ASHRAE Technology Awards: Optimizing Building and HVAC Systems PDF

Argues that buildings designed and constructed using an energy design process that optimises the interaction between the building envelope and systems can save between 30% and 75% in energy costs. These buildings can be constructed for the same or nearly the same first cost as non-energy efficient building with no sacrifice of comfort or functionality. Describes the application of this energy design process to design and construct the 10,000ft² Thermal Test Facility (TTF) at the US Department of Energy's National Renewable Energy laboratory. Details the daylighting strategy, the energy-efficient building envelope and HVAC system loads and operation. Sets out the nine-step process for low-energy building design. States that actual performance data collected for more than one year show that the TTF costs 63% less to operate than an equivalent building which complies with ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings.
