RETREAT integrates low-tech components widely available today into a factory-assembled enclosure that uses the passive design approach of super-insulation, air tightness, thermal bridge-free details, compact form, winter passive solar, and summer shading to achieve deep energy reductions. R-values range from 32 at the glass walls and roof to 87 at the floor. The materials have very high insulation value with minimum thickness: Triple-pane insulated glass units; Aerogel Thermal Wrap at shades; VIPs (vacuum insulated panels) at floor and walls.
