West Village Landmark Townhouse Retrofit

West Village Landmark Townhouse Retrofit

This classic New York City landmark townhouse, built circa 1900, exemplifies the beautiful typology of many old Manhattan neighborhoods.

Unable to alter the exterior façade because of strict citywide landmark preservation laws, a continuous new layer of insulation will be added along the interior of the building. Existing windows will be removed and new triple-glazed windows will be installed.

The interior heating and cooling of the townhouse is addressed with the installation of an air exchange unit. The air exchange unit provides the entire townhouse with fresh outdoor air that has been appropriately tempered minimizing the reliance on expensive traditional heating and cooling strategies. These retrofitting strategies, among others, are aimed at bringing this turn of the century townhouse construction up to Enerphit standards. This townhouse will use 60-80% less energy than a traditional townhouse while maintaining the exterior landmarked aesthetic.

Similarly, these new building techniques can be applied to a variety of building types and scales that would like to benefit from a more efficient envelopes resulting in cost savings.
