For this Brooklyn Multifamily Passive House project ZH designed the conversion of a three story Brooklyn row house into a 5 story, 7,000 SF, 8 unit Passive House rental property with a 15’ rear addition and a two story enlargement. We were chosen for this project not only for our design sensibility and Passive House expertise, but also for our strong relationship with a variety of Passive House specialists. This network helps ZH to quickly optimize the energy performance, cost, schedule, and aesthetics of the project while maintaining the highest quality in design and construction. For St. John’s Place this expertise was crucial in meeting the challenges of the project, which included the ambitious goal of constructing the Passive House multifamily conversion, enlargement and addition at the same cost per square foot as a standard building.

While in preliminary design stages, we needed to quickly evaluate the project detailing strategy for all disciplines in order to come up with an airtight and thermal bridge free envelope design expected to surpass the necessary 0.5 air change per hour requirement for Passive House performance. Further energy analysis has allowed us to precisely calibrate the balance between our client’s requests for larger windows and the necessary solar shading to achieve Passive House standard without compromising interior comfort. This project will also be a Pilot Project with NYSERDA in order to study the performance of Passive House in relation to NYSERDA’s own energy and building targets.

St. John’s Place was used as a Case Study Project by Passive House International (PHI) for the new Passive House Classes being introduced under the latest PHPP Version 9.0. The new Passive House Classes are meant to push the performance standards to an even higher benchmark by requiring PH projects to generate power on site. The additional passive house categories include 1.Classic, 2. Net Zero and 3. Net Positive under both the retrofit and new building typologies respectively.

The project is currently on site.
