Midtown Passive House

In curation License 

To further define its market position on high performance homebuilding, Brookfield worked with IBACOS and the Building America program to design and construct a Passive House (PH) certified[1] model home to evaluate advanced building technologies and to use as a marketing tool for potential homebuyers. Brookfield used a new architect and a new floor plan as a standard production model and constructed it to the PH standard as an upgrade option. This PH was completely built and certified in August 2013.

IBACOS worked with Brookfield to identify a package of measures that would achieve PH certification and be implemented in an occupied test house. To accomplish this, the project team used several modeling programs and calculation methods such as BEopt, THERM, and a Passive House Planning Package (PHPP) model, as well as Air Conditioning Contractors of America (ACCA) Manual J and Manual D calculations. Short-term performance testing in the test house was accomplished with a variety of equipment. A calibrated low-flow balometer to measure the airflow from each supply register in each conditioned room. The team also used a duct blaster to measure total air leakage through the duct systems and total air leakage to the outside; total duct leakage was found to be 38 cfm. Testing with a blower door indicated that whole-building air leakage to the outside was 324.5 CFM and 0.60 ACH50. Room pressures, measured using a digital manometer, ranged from 0.2 to 0.6 Pa with the heating, ventilation, and air conditioning (HVAC) system running. Likewise energy recovery ventilator (ERV) balanced airflows measured in the laundry room were 114 cfm during the cooling season.
Since PH certification of the test house in August 2013, IBACOS and NREL have undertaken the task of long-term monitoring of the PH test home to measure whole-house comfort and energy consumption. IBACOS will present the long-term monitoring test results in a future report.
