Torcellini Residence
General Energy Use, Strategies and Systems
Energy Use:
- Passive design
- Air-to-water heat pump for providing heat for radiant floor and hot water
- Ductless mini-split heat pump for cooling and supplemental heating
- 9.4kW PV System
- LED Lighting throughout the home
- Root cellar outfitted with battery storage system for times when the grid is down.
Energy Strategies:
Relying on passive design, the home’s orientation maximizes solar gain during cold months while generous
overhangs provide summer shading.Cooling and supplemental heat are
provided by a ductless mini-split heat pump. Double stud walls with 12” of blown in batts (BIBS) are R50 and
the cathedral ceilings with strapping on rafters are R55 (BIBS) while the attic area is over R80. Solar panels
are clip mounted on a 30 degree metal roof system providing 9.4kW of renewable energy. Energy efficiency is further enhanced by LED lighting
throughout the home.
