INNER CITY NEW HOME CONSTRUCTION
Mix of conventional and ICF construction
Timeline - 10 months
SCOPE: contracted 3 custom, inner city homes (infill shown above and duplex), inner city Calgary. These are Energy Guide rated homes build on a tight
ICF used in the basement and the party wall. An ICF party wall provides superior fire and noise detination. Duplex neighbors cannot hear eachother through a thick concrete party wall. The ICF is tested to be far superior in insulative performace and fire resistant to other building methods. Hydronic heating was used in all three homes, no furnaces to blow allergens through the home.
Large windows placed strategically allow for maximum natural light, solar gain and minimal heat loss. Tile flooring maximizes heat transfer from in-floor heating lines, minimizes chemical offgassing and increase life of floor. Allergy and asthma symptoms were drastically reduced for the enviromentally sensitive owner.
All three homes are solar-ready. The hydronic systems also heat the attached garages. Mineral wool insulation (ROXUL) was used in exterior walls while spray foam insulation was used in joist spaces and difficult places such as wall corners. This process provides an EnerGuide 80+ rating without the expence of full ICF.
Outdoor overhead lines (electrical, phone) were buried under ground so they do not pass over the back yard. The 2-car garage is also hydronically heated on its own zone.
This residential project in Rockyview County demostrates how our building philosophies can be priced competitvely with new houses of similar square footage in the area.
