The Commercial Rooftop Heat Island Problem
Commercial buildings in Dallas are both victims and contributors to the urban heat island. Dark rooftop materials and waste heat exhaust are driving up cooling costs.
- Rooftop ambient: 115–125°F
- RTUs lose 15–25% cooling capacity above 100°F
- SEER degrades from 13 to 8–9 in 120°F+ conditions
