A modern retrofit of a 50-year-old New York home will leave you breathless. The terraced energy-efficient residence in the Village of Mamaroneck in Westchester County is both a retrofit and extension of an existing house built in 1963. Benzing Architects designed the project for a private client, using the existing footprint and first floor framing as the renovation's foundation. The design has won the 2015 EBie Awards, Urban Green Council`s "Oscars of existing buildings" in the category -Power to the People- for the greatest percentage reduction in building energy use.
The architects deconstructed the existing roof and recycled all the asphalt shingles, added a second floor and converted the south side of the roof into a large terrace that offers views of the harbor. An additional layer of thermal insulation was added to the two-story high wooden frame and the entire building received a vented horizontal cladding.
A red wooden pergola on the south side provides shade during the summer and reduces heat gain. The efficient ventilation system has an effective heat recovery performance of 70.9%, while the flat part of the roof boasts 28 solar panels with a capacity of 6.7 kW and inverter technology.
The statement released by the client speaks of the efficiency and performance of the completed project: “The house feels super healthy: I wake up in the morning without the urge of opening a window to ventilate: my indoor air is filtered and completely replaced with fresh outdoor air every 3 hours. The air does not feel dry compared to what it was with the former heating system and my sinuses are happy which relieves me from the splitting headaches I used to wake up with. A total bliss!“
