E Cube Made with SIPs Housing System

It seems like a major component of green building these days is reducing energy demand and building ultra-low energy homes.  For instance, British Columbia-based Jenesys Buildings Corp. built this E Cube house with a superinsulated shell of SIPs in an effort to deliver a home that’s twice as energy efficient as a comparable home built to standard code requirements.

Specifically, E Cube has 8-inch wall SIPs (R36), 6-inch crawlspace SIPs (R26), and 10-12 inches of batt insulation with 6-inch roof SIPs (R64).  The home also has double-glazed, argon-filled, low-E, Energy Star windows strategically placed to optimize passive solar gain.

Frederick Brummer, Assistant Manager at Jenesys, told me in an email that the E Cube has an air-to-air heat pump for air conditioning and back-up space heating, but the air conditioning hasn’t been needed due to the superinsulated SIPs shell.

E Cube also has a heat recovery ventilator and is optimized for natural cross ventilation.  Solar thermal collectors pre-heat domestic hot water, while a grid-tied solar photovoltaic array generates power for the home.

The kitchen is outfitted with IKEA cabinets and wardrobes.  Also, E Cube is clad in a fiber cement rainscreen, while a green roof helps reduce stormwater runoff.   For the curious, E Cube, a 2,244 square-foot home, was built for $201 per square foot, including the garage but excluding solar technology and landscaping.
