Describes the features of a prototype home designed for a large builder in Michigan, USA, and the results of a series of DOE-2.1E energy simulations performed to assess the impact of various energy efficient aspects. The new features included: improvements to the thermal envelope and mechanical equipment; use of structurally insulated panels (SIPs) for the envelope; high performance, low-E argon-filled windows; a smaller, more efficient boiler; passive cooling design via a central stairwell with operable skylight; a unique mechanical ventilation system that can be scheduled and zoned.
