The project is a single family home, 4 stories plus cellar, for a family of six with young children. The cellar was lowered in order to create more height in the upper living areas. There is a double height space connecting the lower level basement living room with the dining room on the parlor level, thus the passive house windows are in a two-story configurations. These windows are wood on the interior and aluminum clad on the exterior. The windows also have an exterior shading screen made of bronze rods, a material that has been utilized throughout the interior of the project also. The building is Landmarked, thus the front facade windows had to be simulated double hung windows. We worked closely with the window manufacturer to work out details that would be acceptable to Landmarks in terms of thickness of stiles and rails. The clients were interested in having a greenhouse/sunroom space, however due to zoning regulations we were not able to build up. So we decided to take it out of the master level of the house, which is the third floor. This sunroom has a very large skylight over it, and thus had to be outside of the passive house boundary. This created some unique challenges in detailing how the passive house boundary wrapped around this space.
