Prefab Grows up

ART House ws a joint effort bewteen J.B. Clancy of Albert, Righter & Tittmann Architects, energy-analyst Peter Schneider of Efficiency Vermont, Green Mountain Habitat for Humanity, and modular builder Preferred Building Systems.

From order to delivery, a modular house like this one would take about six months. Built with volunteers, this one took eight months.Here, modular boxes are set on the home's foundation.

The home has high levels of insulation and air-tight construction. Here, roof panels are put in place.

Appliances are EnergyStar, and the home is lit by daylight and by compact fluorescents and LEDs.

Windows are triple-glazed, there's a solar thermal system for hot water, a heat-recovery ventilation (HRV) system.

Insulated concrete forms (ICFs), and heavy timber framing work in tandem with the panels.

The house was rebuilt by the owners after a tree fell on their summer house. They decided to build a high-performing replica for year-round enjoyment.

Lakeside Green's designer, Dennis Feltner, was familiar with SIPS and the area’s architectural review board’s requirements. White cedar was harvested from within a 250-mile radius for siding and the original cottage’s heart pine floors and plumbing fixtures were reused.

The house was finished with recycled fibre boards and wood. The house is in South Central LA, and there's even a Facebook discussion thread amongst the neighbors about how happy they are about the change in the 'hood.

Scott Bergford, founder of Scott Homes in Olympia, WA,was an early adopter of the SIPs used to build this Craftsman.

Bergford has focused for decades on exceeding EnergyStar guidelines,but the economy was a catalyst to push energy efficiency even further.

Sea Breeze Cottage has a 15 SEER (seasonal energy efficiency ratio) heat pump that heats and cools through air ducts sealed to reduce leakage. PV cells were integrated into asphalt roof shingles. Direct-vent fireplaces cut drafts and heat loss. Almost 30 feet wide, the beach cottage design features a front porch, peaked roof, and is designed for good cross ventilation.
