Greenstone Construction specializes in constructing some of the most energy efficient homes in Calgary. We work with clients and architects to find a balance between budget, quality, and environmental efficiency. It's not just about doing our part for the environment. Houses designed to exceed even the most stringent building codes are simply more comfortable, and pleasurable to live in. In short, a higher quality of life. Designed to be in harmony with the environment, we try to engineer out common annoyances such as over-heating in summer, and cold-spots and drafts in winter.  We take the time to think through likely issues and mitigate them by using a smarter building design.  This can reduce HVAC (heating, ventilation, air-conditioning) equipment and installation costs, and helps to keeps utility bills among the lowest achievable in our climate.  



Bearspaw Residence, Calgary

contemporary design, modern construction, Full ICF home

From basement to rafters, this home is fully built out of concrete. The walls are build from ICFs (insulated concrete forms) with an 8" solid concrete core and a suspended concrete slab for both the main and upper floor.  The design incorporates passive solar heating and cooling principles. Careful attention was given to the position of the home in relationship to the sun, glazing design, awning placement, and thermal massing. The result is a home that maintains a stable temperature in even the harshest weather, and requires very little energy to heat and cool.

Parkdale Residence, Calgary

Accessible home with ICF basement

Designed and built to be completely barrier-free to meet the current and future mobility challenges for this family. With curb-less showers, right-size doorways and passageways,  zero-grade entrances at front and rear of the house, and an elevator that accesses all floors, Greenstone worked to ensure that this house maximizes independence and autonomy for each member of the family. The basement walls incorporate ICFs (insulated concrete forms), with the above grade walls incorporating advanced framing and air sealing techniques to increase the home's energy efficiency and durability.

Kensington Residence

High-end Home

Built on a small lot in the sought-after Kensington neighbourhood, this home demonstrates the customary modern flair found in so many Calgary in-fills. But this home is far from customary when you look at the details. The design incorporated ICFs (insulated concrete forms) for the foundation, with all exterior wall cavities receiving closed cell spray foam. The result is an air-tight, energy efficient building envelope, and a home that requires much less energy to operate. A heat recovery ventilator was incorporated into the heating system to further improved energy efficiency. Finally, the garage was designed with a "green roof" to allow the homeowners to maximize their green space, even on a smaller city lot.

Altadore Residence

ICF basement with conventional wood frame 

Basement walls were built from ICFs (insulated concrete forms) to increase the home's heat efficiency and durability.  The remainder of the house incorporates a more familiar wood framed structure. Imported European cabinets accentuate the 10 foot high ceilings and the open floor plan. The exterior of the home is a combination of Hardie Panel siding with Easy Trim reveals and cedar. This home is truly a work of art.
