Blower Door Test Results At
1717 Arlington Street

💨Get Ready To Be Blown Away With These Results!⁣

📅At the end of March, we had our pre-blower door test done at 1717 Arlington Street.⁣

On June 14th, 2021, Rob Hewski from Northeast AeroBarrier came again to do our final test right before certificate of occupancy. 

🌀In a MBD (multipoint blower door) Test, the building’s actual CFM (cubic feet per minute) is determined at different pressures. ⁣

🌀For the results to be official, it should be plotted in a straight line or close to it. ⁣

❗️The results are to be plotted to measure the infiltration at any given pressure providing more accuracy than a single point test. ⁣

🧠 𝐈𝐧𝐭𝐞𝐫𝐞𝐬𝐭𝐢𝐧𝐠 𝐅𝐚𝐜𝐭𝐬👇🏻⁣
🔹The rings on the fan are called flow rings.
🔹 The smaller the ring size, the less makeup air needs to maintain 50 pascals of pressure inside the building, meaning a tighter envelope.⁣

Our Results?!


2.93 ACH 🙌🏻🏆⁣

🔹 The infiltration level required is 5 ACH or less. ⁣

⬇️The lower the rating, the better air tightness and energy efficiency.⁣

✨However, we build to achieve under 3 ACH as our standard at GRIT.

Special 𝐭𝐡𝐚𝐧𝐤 𝐲𝐨𝐮 again to @northeast_aerobarrier for coming out to train us and perform our test 🙌🏻⁣

🤝Clients: Vikara Social Development and P-Squared

✍🏻Architect: Gnome Architects

🧱 If it’s GRIT built, it is a building you can depend on because GRIT cares. ⁣
