• Heat pump uses efficient R410-A refrigerant, eliminating HCFCs and CFCs that cause global warming
• All-electric house means no fossil fuels
• Six-kilowatt grid-tied PV solar system means close to net-zero annual energy consumption
• Envelope insulated to 50% above code (R30 walls, R40+ ceilings)
• High performance staggered-stud walls allow continual thermal barrier with minimal thermal bridging
• Reflective metal roof with air gap to reduce summer heat gain
• Panasonic WhisperGreen™ bath fans run continuously ventilating without an HRV; motion sensors increase fan speed during use
• High-efficiency lighting design uses Energy Star, fluorescent, LED and halogen task lighting for maximum performance-per-Watt
• Energy Star fiberglass windows
