Whole House Mechanical Ventilation (WHMV) Specifier
code compliant solutions for one and two family dwellings and townhouses up to three
The latest model building codes and standards* now require an exhaust, supply, or combination exhaust/supply whole house mechanical ventilation (WHMV) system in residential dwellings. This WHMV Specifier is provided by Broan-NuTone to assist building professionals with sizing and specifying WHMV systems that are in compliance with the latest codes and standards and that can be ranked according to your client’s individual preferences. In the absence of state or program requirements for WHMV in your specific location, the WHMV Specifier recommends options for ventilation fans that that can be used to satisfy the WHMV requirements of ASHRAE Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. Always check with your local jurisdiction for the specific code requirements in your area.
Let’s get started by selecting the state where the dwelling unit will be located.
*The 2012 International Residential Code Sections N1103.5 and M1507, the 2012 International Energy Conservation Code Section R403.5, and ASHRAE Standard 62.2.
