Make your home part of the most sustainable trend in home building today.

Net-zero homes are homes that produce as much energy as they use on an annual basis, so they aren’t a drain on natural resources.

NET ZERO ENERGY

The most cost-effective steps toward a reduction in a building's energy consumption usually occur during the design process. To achieve efficient energy use, zero energy design departs significantly from conventional construction practice. Successful zero energy building designers typically combine time tested passive solar, or artificial/fake conditioning, principles that work with the on-site assets. Sunlight and solar heat, prevailing breezes, and the cool of the earth below a building, can provide daylighting and stable indoor temperatures with minimum mechanical means. Kondro’s NZE homes are normally optimized to use passive solar heat gain and shading, combined with thermal mass to stabilize diurnal temperature variations throughout the day, and in most climates are superinsulated. Kondro homes use all the state-of-the-art technologies needed to craft zero energy homes in Alberta.

Kondro's Zero-energy homes are built with significant energy-saving features.

The heating and cooling loads are lowered by using high-efficiency equipment, added insulation, high-efficiency windows, natural ventilation, and other techniques. These features vary depending on climate zones in which the construction occurs. Water heating loads can be lowered by using water conservation fixtures, heat recovery units on waste water, and by using solar water heating, and high-efficiency water heating equipment. Nighttime illumination is typically done with fluorescent and LED lighting that use 1/3 or less power than incandescent lights, without adding unwanted heat. And miscellaneous electric loads can be lessened by choosing efficient appliances and minimizing phantom loads or standby power.

Superinsulation is an approach to Kondro Homes design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher levels of insulation and airtightness than normal. There is no universally agreed definition of superinsulation, but superinsulated buildings typically include:
 

Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m²·K) respectively)
 

Details to ensure insulation continuity where walls meet roofs, foundations, and other walls • Airtight construction, especially around doors and windows to prevent air infiltration pushing heat in or out • A heat recovery ventilation system to provide fresh air • No large windows facing any particular direction • Much smaller than conventional heating system, sometimes just a small backup heater
