This high performance, sustainable home, was built in the neighborhood of Rosemont, located in Calgary's northwest. With its many beautiful finishes, the home is not only energy efficient, but also aesthetically pleasing.
The home was designed with several criteria being considered. Energy efficiency, sustainability, functionality, style and of course budget were all taken into account when designing and constructing the home.
The structure is two stories, with 3,566 square feet above grade and 1,568 square feet of developed space in the walkout basement. There is a single attached garage and a detached, double car garage, providing ample storage.
Super low energy needs was the name of the game on this project. The easiest way to conserve energy is not to require it in the first place. To achieve this, the building envelope is made up of a proprietary R37, double framed wall which is air tight. Virtually all thermal bridging is eliminated using this building envelope.
The ceiling and roof utilize a similar envelope design, where an air tight seal is covered with blown cellulose insulation providing a thermally broken, R60 barrier.
Innotech's triple pane, European style windows have been utilized to limit heat loss through glazing.
Using these and other high performance construction techniques, this home has achieved an exceptional air exchange rate of 0.52 air changes per hour (ACH)! This is 8 times better than your typically built home, and fulfills the requirements for Passive House certification!
The mechanical system is comprised of a natural gas boiler which feeds two fan coil furnaces and an 106 gallon indirect domestic hot water tank. This is accompanied by a Lifebreath 155 Max HRV system which pre-heats fresh air with heat recovered from the air being exhausted from the home.
This design resulted in a home with an Energuide score of 88, meaning it uses 60% less energy as compared to a typically built home. A home built to today's standards would score approximately 70 on the Energuide scale.
Besides all of this, the home provides an extremely comfortable environment for its occupants and the best part is that the additional cost for all of this performance and energy efficiency was approximately 5%!

This high performance, sustainable home, was built in the neighborhood of Echo Haven located at Rocky Ridge in Calgary's northwest. The home has two stories, with 2,186 square feet above grade and an oversized double car garage. The home was designed with several parameters being considered. Energy efficiency, sustainability, functionality, style and of course budget were all taken into account when designing the home.
The building envelope is made up of a proprietary R50, double framed wall which is air tight. Virtually all thermal bridging is eliminated using this building envelope.
Using this and other high performance construction techniques, this home achieved an unprecedented air exchange rate of 0.7 air changes per hour (ACH)! This is 6 times better than your typically built home.
Triple pane windows were utilized to limit heat loss through glazing.
The mechanical system is comprised of an air source heat pump which is up to 330% efficient, yes that's correct, for every kWh of electricity put into heating or cooling the home, the heat pump supplies up to 3.3 kWh from the environment! This is accompanied by an HRV system which recovers heat from the air being exhausted from the home.
Other technologies are also being utilized such as drain water heat recovery.
All of these features resulted in a Net Zero Ready home with an Energuide score of 89, meaning this home uses only 1/3 of the resources as compared to a typically built home, thats 66% less. With the addition of a photo-voltaic solar system, which is already roughed in, this home will use 0 external energy!
The most amazing part... All of this was achieved with an increase in build cost of around 10%!

This high performance, sustainable home was built in the neighborhood of Wildwood. The home is two stories, with 2,442 square feet above grade, a developed basement and a detached double car garage.
The home was built with energy efficiency and sustainability at the forefront. The home was rated using the Energuide & BuiltGreen programs, which allowed it to be evaluated on both its energy efficiency and sustainability. At the time when the home was built, the government had a program in place which rewarded the consumer with $10,000 for achieving an Energuide score of 86, so this was of course the goal.
Through the use of Hillson's advanced building techniques, modern materials and attention to detail during construction, this home achieved an outstanding 1.0 air changes per hour (ACH) during the final door blower test. This exceeds the standard set by LEED for Homes by more than double!
The home was insulated with 3" of closed cell spray foam around the exterior of the foundation to create a large thermal mass for retaining heat. Another 5.5" of closed cell spray foam was used in the exterior walls above grade and a 3" layer in the attic to make the home air tight. On demand hot water heating fed by a solar thermal collection system was utilized for the domestic hot water. This results in almost 100% of the home's hot water needs being supplied by the sun. Given the air tightness of the home, a Heat Recovery Ventilator (HRV) was incorporated to circulate, replenish and exhaust the air throughout the home, an important task for such a well sealed building. The HRV brings in fresh air from outside and tempers it with heat recovered from outgoing exhaust air.
As a result of the many features integrated into the home, an Energuide score of 86 was achieved, which resulted in a rebate of $10,000 for the customer. The home also achieved a Gold BuiltGreen rating. All of this was achieved at an additional cost of only 3.8%!
This high performance home was built in the neighborhood of Bridgeland, in the heart of Calgary's Inner City. The home is two stories, with 2,700 square feet above grade, a developed basement and a detached double car garage.
The owners wanted an environmentally integrated home which would be energy efficient, comfortable, durable and functional for their growing family. Everything a high performance home should be.
Through the use of Hillson's advanced building techniques, modern materials and attention to detail during construction, this home achieved an outstanding 0.89 air changes per hour (ACH) during the final door blower test. This exceeds the standard set by LEED for Homes by more than double!
Heating for the home is provided by an in-floor system driven by a natural gas, super high-efficiency boiler, which also heats the domestic hot water. With such cold winters, most houses in Calgary would augment an in-floor heating system with a forced air furnace, however the superior insulation and air tightness of this home makes its heating demand low enough to be served perfectly well by in-floor heating alone. Given the air tightness of the home, an Energy Recovery Ventilator (ERV) is utilized to circulate, replenish and exhaust the air throughout the home, an important task for such a well sealed building. The ERV brings in fresh air from outside and tempers it with heat recovered from outgoing exhaust air. In such a dry climate as Calgary, it is also important to maintain humidity levels in the home, which the ERV also accomplishes by recovering humidity from the exhausted air and introducing it to the incoming air.
As a result of the many features integrated into the home, an Energuide score of 83 was achieved.
