The growing use of plug loads coupled with insufficient data on how much energy they generate present a challenge to engineers in determining how to best cool a building. Heat gain from persons in air conditioned spaces - in btu/hr. When predicting annual building energy/cost/carbon performance, we do not encourage this approach and use hourly operational profiles instead. &w Perimeter zones shall be no more than 4.7 meters (15 feet) from an outside wall along a common exposure. With more than 50,000 members from over 130+ nations, ASHRAE is a diverse organization dedicated to advancing the arts and sciences of heating, ventilation, air conditioning and refrigeration to serve humanity and promote a sustainable world. The updated values of typical heat gains.
