1. Significantly reduces HVAC system size
2. No more need to pressurize building?
3. Special routine for high-rise towers
Take Two:
1. HVAC efficiency + 15%
2. Lighting power – 25%
3. Digital lighting controls
4. Solar
5. DOAS
6. Water heating type
7. Envelope UxA – 15%
8. Air leakage 0.25 Group R … 0.22 cfm all other
Close to full energy code compliance for major remodels
“…substantially extend the useful physical or economic life of the building”
•Max 150% of ASHRAE 62.1 ventilation rate to each zone
•DOAS requires energy recovery• …or at least it was supposed to
