This free tool allows designers to select floor area and modify number of bedrooms, duct size and duct length, and quantity of duct fittings for the purpose of calculating CFM, duct velocity and friction for both the 2011 and 2013 versions of ASHRAE 62.2 - Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. Output includes differential comparison in CFM, friction loss and duct size as a result of CFM change from the 2011 to the 2013 version.
