Federal Study Quantifies Efficiency Losses Due to Improper HVAC QI.
It has long been recognized that design and installation faults have an impact on the capacity and efficiency of HVAC systems. However, the magnitude of these fault impacts as well as whether some faults cancel out other faults was unknown. A four-year investigation was recently concluded by the National Institute of Standards and Technology (NIST; a U.S. Department of Commerce Laboratory) that quantifies the consequences of failing to observe the design and installation elements contained within the ANSI / ACCA 5 QI Standard (HVAC Quality Installation Specification). This webinar will summarize the NIST results: the effect of installation errors (e.g., leaky duct, improper refrigerant charge, oversized equipment, incorrect air flow, etc.) on the performance of residential unitary equipment; the extent that operational deviations are significant; whether the deviations (when combined) have an additive effect on equipment efficiency; and whether some deviations are affected by geographical/climatic differences. With an understanding of this information, field personnel are better positioned to focus attention, resources, and remediation effort on the varied design, installation, and maintenance practices in the HVAC sector. The target audience for this webinar are building officials, builders and contractors.
