PHIUS Local Climate-Specific Thresholds.
- ASHRAE 2013 & Global Solar Radiation Location = London, ON Airport, Zone 5
- Annual heating demand 6.6 kBtu/sf-iCFA.yr x 3.155 = 20.8 kWh/m2/yr
- Annual cooling demand 1.8 kBtu/sf-iCFA.yr x 3.155 = 5.68 kWh/m2/yr
- Peak heating load = 4.8 BTU/sf-iCFA.h x 3.1546 = 15.1 Watt/Square Meter (W/m²)
- Peak cooling load = 3.8 Btu/sf-iCFA.h x 3.1546 = 12.0 Watt/Square Meter (W/m²)
- PHIUS Recommended max window U value = 0.14 Btu/h.sf.F
