Solar Café Energy Efficiency

 

SIP CONSTRUCTION

The Solar Cafe is constructed with Structural Insulated Panels (SIPS)

Thermal bridging of the wood members in traditional wood frame construction

reduces the R-Value of the building. SIP constuction has less wood members

and all panel joints are sealed. The Solar Cafe has 6" SIP walls (R-24), 10" SIP

sloped roof panels (R-39) and a 12" SIP flat roof section (R-47).

GEOTHERMAL LOOP

The building is heated by a concrete radiant floor using a Horizontal Geo Loop system.

600 Ft of trench was dug 3' wide by 5' deep with 6 loops of pipe or 1800' of pipe.

The constant temperature of the waterbased solution circulating in the pipe allows a

Water to Water Heat Pump to efficiently heat the building. The system also assists the building's hot water supply through a heat exchanger.

PASSIVE SOLAR

South facing windows produce solar gain in the winter months. Overhangs are

designed to shade the windows in the summer months.

LIGHTING

The building receives an abundance of natural light.

Other lighting consists of T8 Flurescent, Compact Fluorescent, Low Voltage and LED fixtures.
