A preliminary analysis of recent HVAC energy projects
- General Services Administration, San Francisco, CA (United States). Pacific Rim Region
A typical Government HVAC design over the last 30 years consisted of two oversized (equal tonnage) electric chillers, two oversized (equal NBTU ratings) boilers, an air economizer cycle, a constant air volume system and a central station pneumatic control system. This typical basic layout for plant design has certain advantages such as simplicity and ease to construct throughout the country. The cookie cutter design/build approach suited federal facilities, when utility costs were not a major consideration, in-house maintenance and operations personnel were plentiful and energy conservation was a moral priority and not an economic concern. Those days are history as energy costs have escalated and operating budgets continue to shrink leaving fewer personnel to maintain the same buildings. Advances in HVAC technology and the reduction in costs for energy efficient systems have finally started affecting the Federal Government`s HVAC replacement and new construction designs. This paper is a brief description of three HVAC projects that go outside the traditional government HVAC design parameters. GSA`s Pacific Rim Region, covering the states of Hawaii, California, Nevada, and Arizona, has implemented three HVAC projects utilizing different technologies not normally found in GSA Federal facilities.
