April 4, 2005: CEC Offers Guide For Improving Rooftop Unit Performance
SACRAMENTO, Calif. - The Small HVAC System Design Guide, produced by the California Energy Commission (CEC), offers design guidance on how to improve the installed performance of small packaged rooftop HVAC systems in commercial building applications. The document is written for architects, engineers, and design/build contractors.
The guide includes information and advice on overall building design practices to minimize HVAC loads, unit selection and sizing, distribution and control system design, commissioning, and operations and maintenance. According to the guide, by applying the integrated design principles in this document, the energy consumption and costs of buildings with small HVAC systems can be reduced by 25 percent to 35 percent.
