Solar Air Heating Project Solar Air Heating Project ConsiderationsConsiderations
• Most cost-effective in new construction and renovationMost cost-effective in new construction and renovation Cladding credit Ensure that existing ventilation system accommodates SAH easily
• Most dark colors have absorptivity of 0.80-0.95Most dark colors have absorptivity of 0.80-0.95 Architectural concerns can be very important
• Higher occupancy Higher occupancy more cost-effectivemore cost-effective
• Can be fitted around Can be fitted around windows and doorswindows and doors
• Existing fans & Existing fans & ducting can be usedducting can be used
• Low or no added Low or no added maintenance costsmaintenance costs

• Only 12 points of data for Only 12 points of data for RETScreenRETScreen®® vs. 8,760 for vs. 8,760 for hourlyhourly simulation modelssimulation models
• Currently not covered:Currently not covered: Advanced HRV systems Non Solarwall® technology Unbalanced ventilation systems
• SAH provides ventilation and process air heatingSAH provides ventilation and process air heating
• Locations throughout world have solar energy available when Locations throughout world have solar energy available when ventilation air heating is requiredventilation air heating is required
• SAH serves as weather cladding and feeds into conventional SAH serves as weather cladding and feeds into conventional ventilation systems ventilation systems
• For SAH systems, RETScreenFor SAH systems, RETScreen®® calculates calculates Energy collected, efficiency, and temperature rise Wall heat loss recovery
Reduced heat loss due to destratification
