Greer Residence, Lewes Delaware

This project is designed according to "Passive House" principals, wherein the shell is made so tight and well insulated almost no mechanical energy is required to keep it comfortable. With 12" thick structural insulated panel walls and attic plates the home has an insulated envelope of R-60. Very careful detailing of seams and mechanical systems will reduce air infiltration to near zero, so that all fresh air can be brought in mechanically and passed through heat exchangers. It is anticipated that the home will require less than ½ ton of mechanical equipment. It also features multiple photovoltaic panels on a south facing roof of 38.6 degrees, providing optimal orientation, and should provide all of its own power.

From the street, the house is designed to be compatible with its very traditional neighborhood. It takes a dramatic twist at the back, however, to provide a large roof area facing due south and pitched at the ideal angle for photovoltaic panels. The panels are expected to provide all of the energy required by the house.
