ARLINGTON, Va. — ACCA has published a new technical bulletin entitled “Ensuring ASHRAE 62.2-2013 Ventilation Compliance for Residential Structures.”
This technical bulletin is particularly important for contractors who are currently following ASHRAE 62.2-2010, because ASHRAE made major modifications to its latest update ANSI/ASHRAE 62.2-2013 “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings.”
The technical bulletin covers the changes in three parts: Part 1 covers requirements for every new home under construction or for existing homes when HVAC systems are being added; part 2 covers ventilation designs (new and add-on applications) that have variable or intermittent operation; and part 3 covers some of the additional considerations that may, or may not, apply to varied applications.
Additionally, there is an appendix that summarizes various mechanical equipment approaches for meeting the ASHRAE 62.2 requirements and highlights the advantages and disadvantages associated with each approach.
