Mr. Dwight Benedict: Y C 0-?
After inspection of the New 2 Story Home at 17 Kenmore Drive, Queensbury,New
York and completion of a Blower Door Test consistent with the practice of
depressurization to 50 Pascal in a winter condition with the exterior windows and
doors shut and the interior doors to all the rooms open,my observations are as
follows:
❖ This home tested passed the current New York State Building Code for Air Changes
per Hour @ 50 Pascal of less than or equal to 3 ACH/50(for Homes permitted after
November 1st, 2016). The tested number is 2.094 ACH/50 Pascal.
❖ The total volume of conditioned space at 17 Kenmore Drive is 53461 cubic feet
taking into consideration all conditioned space in the home. The cubic feet per
minute @ 50 Pascal was 1866 CFM/50. The height correction factor for New York
State is 15.4 for a two story home, as such the tested home @ 17 Kenmore Drive has
the natural rate of air exchange of 0.136 air changes per hour/natural or 121 cfm
natural air infiltration credit based on the blower door test.
❖ In the latest(2013)version of ASHRAE 62.2,high-performance homes need to be
ventilated at 7.5 cfin per bedroom+ 1,plus 3 cfin per 100 square feet. That means for
3+1 bedrooms it would need 3100 sq ft/100 times 3 cfm 93 cfm+30 cfm or 123
cfm total, and consequently the home has a slight deficit for natural air turnover. It
would also be advantageous to use the bathroom and/or kitchen fans to help control
humidity and improve indoor air quality.
