Radiance Cohousing - Fossil Free Economics:
9Townhouse Units (9,400 sq ft total)
• All units pre-sold
• $250,000 for 775 sq ft to $360,000 for 1,225 sq ft
• 3 million total project cost: includes land, garage, landscaping, prof. fees
• Construction contract = 1.87 million ($200 per sq ft)
• Approx. annual space heating cost of $150 per unit
• Remaining energy provided by renewables
Passive House Investment
• $177,600 – 6% increase in project cost due to:
• Improved Insulation,Airtightness,Windows,Ventilation systems
• Increased monthly mortgage costs are offset by energy cost savings
Project Energy Savings Per Year (compared to natural gas boiler)
• 158,000 kWh (which saves $5,900/yr and reduces CO2 by 39 tonnes/yr)
• Price of Saved Energy = 4 ¢/kWh (compared to Solar PV at 10-15 ¢/kWh)
• If this project was built in an area where only electric heating was available (i.e. rural/remote
communities), savings would increase to $22,400/yr
Radiance Cohousing:
Success through collaboration
• Working with one-of-a-kind builder, Renew Development Cooperative, through a Construction Management Contract
with Cost-Savings Sharing.
• Amazing design team, led by BLDG Studio.
• Currently discussing collaboration with SES Solar Coop for installation of Solar PV array at no cost to Radiance.
• Currently discussing collaboration with Saskatoon Carshare Coop to host electric vehicle.
• Passive House certified ventilation units being supplied by new local vendor,The Green Builder Supply.
• Centralized air-source heat pump system offers heating and cooling for all units.
• Passive House certified windows by Cascadia Windows (Langley, BC).
• Part of a Canada-wide pilot for Gutex wood fibre insulation (Germany). Supported by the Canadian Wood Council, FP
Innovations, and 475 High Performance Building Supply. Gutex is considering expanding into Canada, which could lead
to forestry industry development potential.
• The innovative Gutex + 2x6 wall system can be applied to deep energy retrofits, as well as new builds.
How can we kickstart the Passive House industry in Saskatchewan?
PACE financing, building code improvements, policy & bylaw changes to support green buildings, education & training,
demonstration projects, incentives, floor space exclusions from property taxes for exterior wall thickness, amongst others.
