Full home remodel, Ditmas Park, Brooklyn, NY. Greenbuild CG

Duncan Residence

Ditmas Park, Brooklyn, NY

This project is a 100 year old victorian style home located in Ditmas Park, Brooklyn, NY, and is a NYC designated landmark building.

Greenbuild was brought in to take over this project when a previous contractor was unable to complete due to business complications arising from the Covid pandemic.

Owner is an architect, and wanted to refurbish the house while also retrofitting the structure to receive an EnerPHit Certificate (Quality-Approved Energy Retrofit with Passive House Components). This certification is issued when it is not possible to achieve the full Passive House Standard available for new constructions.

Passive House is a voluntary standard for energy efficiency in a building, which reduces the building’s ecological footprint — resulting in ultra-low energy buildings that require little energy for space heating or cooling.

To meet the standards necessary for EnerPHit certification, Greenbuild strived to meet the five principles for Passive House building: airtightness, ventilation, waterproofing, heating and cooling, and electrical loads.

Additionally, because the home has been designated a NYC landmark building, special attention had to be paid to accuracy of exterior details such as trim, railings, color, window styles, and more. Greenbuild was able to leverage relationships with a range of suppliers and vendors in order to manufacture or source materials that met the required historical and aesthetics standards.
