The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announces the initiation of development of BSR/ACCA 16 Manual E-201x, “HVAC System Design for Energy Efficient Homes” as a new industry standard.
HVAC designers are increasingly encountering energy-efficient homes, characterized by markedly reduced heating and cooling loads, as a result of numerous national initiatives like the energy conservation code, EPA ENERGY STAR, DOE New-Zero Ready programs, and DOE Builder’s Challenge. ACCA recognized that there is little guidance currently available for HVAC design and selection for these energy-efficient homes; especially, since there is limited manufacturer offerings for lower capacity equipment.
This standard will provide procedures to design/select HVAC systems and equipment for low-load homes that will achieve satisfactory indoor conditions with lower equipment capacity; i.e., resolving ventilation and moisture requirements/issues with low air volume systems while addressing occupant comfort, health, and safety. These procedures will apply as lower capacity equipment appears in the marketplace.
