FEATURE LAFARGE cells on the roof will supply power. Lafarge said the building will give back to the energy grid in summer what it consumes in winter. As a result, the Habitat for Humanity families chosen for the pilot project home won't have to pay for utilities. "Lafarge is proud to support Habitat in this pilot that will show how precast concrete can be used to build highly energy efficient homes while helping members of our community," says Lafarge's Rene Thibault, West- ern Canada Aggregates & Concrete regional president. "National Precast Day is an opportunity to educate en- gineers, architects and students about sustainable con- struction and the ideal occasion to feature a NetZero energy home." "As a longtime supporter of Habitat, Stantec pro- vided the architectural design and sustainability con- sulting for [an] innovative project that offers exemplary environmental performance," adds Stantec Edmonton Region Vice President Keith Shillington. "This results in lower monthly utility costs that make this home attain- able for more hard-working families in Edmonton, while the lessons learned here can be replicated worldwide." Modular building segments see strong gains U.S. nonresidential prefabricated building system de- mand is expected to exceed $15 billion in 2015, an in- crease of 7.8 percent annually, according to the new study, Nonresidential Prefabricated Building, from The Freedonia Group, a Cleveland-based research firm. This is a strong showing compared to the weakness over much of the previous decade. The increased demand is due to recovery in office and commercial construction, coupled with continued gains in institutional, industrial and agricultural construction. The development of new products and technologies, including more tailored de- signs and improved concrete mixes, are also providing opportunities. However, competition from traditional site building will remain intense, and moderating prices for many of the raw materials used in prefabricated building systems will restrain value growth. The study also predicts that among nonmetal building systems, the modular building segment is expected to see the strongest gains, just ahead of the panelized precast concrete segment. According to the report, modular build- ing will benefit from robust growth in both commercial and institutional construction activity, as well as from the growing popularity of prefabricated bathroom and kitchen modules. Gains for panelized precast systems will be driven by increases in office and commercial construc- tion, among the more popular applications for these sys- tems. In addition, technological improvements, including better reinforcement materials, improved concrete mix- tures and greater design options, will support demand.

The method in which the insulated precast panels are con- structed and assembled creates an uninterrupted layer of in- sulation generating a superior level of thermal performance. Load bearing and non-load bearing exterior wall panels vary in thickness from 14- to 17-in. thickness, but both sections include 8-in.-thick layers of continuous insulation. The high- performance envelope assembly has resulted in modeled En- erGuide ratings above 86, allowing Habitat to apply for a $20,000 ($10,000/unit) provincial rebate through Alberta's EnerGuide for New Homes Rebate Program.
