Indoor Air Quality
• Exhaust fans in bathrooms with timers provide added moisture elimination
• Exhaust fan in garage exhausts carbon monoxide
Heating and Cooling
• Heat Recovery Ventilation system allows for fresh air support with heat transfer
• Enclosed foyer provides “heat trap” at primary entrance

• Engineered flexible plumbing tubing with manifold distribution
Green Materials
• Wood flooring
