Standards And Verification Protocols For Commissioning Air Flows In Buildings, Florida Solar Energy Center, James Cummings
Standards And Verification Protocols For Commissioning Air Flows In Buildings, Florida Solar Energy Center, James Cummings
FSEC Energy Research Center®
Commissioning involves three major elements - 1) process, 2) standards, and 3) protocols to verify compliance with the standards. Process is the step-by-step oversight of and involvement in the design, build, and start-up of the facility, to make sure that the design matches the customer's needs, that the design is consistent with good building science practice, that construction matches the construction documents, and that systems and system interactions are properly tested at start-up. This paper does not address process, rather it focuses on the second and third elements -- standards and compliance protocols. It presents standards related to airtightness, air …
Building Cavities Used As Ducts: Air Leakage Characteristics And Impacts In Light Commercial Buildings, Florida Solar Energy Center, James Cummings
Building Cavities Used As Ducts: Air Leakage Characteristics And Impacts In Light Commercial Buildings, Florida Solar Energy Center, James Cummings
FSEC Energy Research Center®
Field testing in 70 small commercial buildings in central Florida identified that building cavities were used as part of the air distribution system in 33 buildings. The various building cavity types (# of buildings in parentheses) are: enclosed air handler support platforms (10), mechanical closets (8), mechanical rooms (6), ceiling spaces (7), wall cavities (6), chases (1), and "other" building cavities (2). Testing found that these building cavities are considerably more leaky than standard ducts and plenums because they are generally not built to the same airtightness standard as ducts. Actual air leakage is a function not only of duct …
