The FlowFinder is unusual in that it’s zeroing goes down to 1/100 Pa. Most are only good around zero to about 2/10 Pa making the FlowFinder exceptional where pressures are low or where there is an alternative route for the air to flow.
The FlowFinder measures 6 to 326 CFM in full zero balance mode and up to 503 CFM in compensated mode. It is super light and small and can measure kitchen exhaust, HRV flows in tight places. The “Killer” application for the Flow Finder is that it can be used on a sales call with a Blower Door to identify and measure duct leakage to outdoors visually and quantitatively. Just use the Blower Door to pressurize the house to 25 Pa, and if smoke moves at the registers, the Flow Finder will measure it allowing the operator to identify the most cost effective work that can be done on a home.
The New York State Energy Research and Development Authority (NYSERDA) funded study shows Passive House for tall buildings in NY can reduce heating energy consumption by 85%. When compared to the base case targeting LEED Silver, the Passive House design saved 47% in energy use intensity while only increasing construction cost by 2.4%. Improved air quality and longevity make this a very good investment over time.
Thank you to NYSERDA for funding the study to determine how the construction industry can become more energy efficient.
Passive House is the equivalent of theGerman PassivHaus Standard.
