Workers begin wrapping the buildings, which is critical in creating a tight building envelope. (August 23, 2005)

This high quality building wrap will assist in sealing the building while also allowing it to "breath" appropriately. This is essential in achieving the energy efficiency of the design.

Drilling begins for the ground source heat pump.

A worker is adding a 10' length of drilling rod as they work their way downward to a final depth of 200'.

The workers begin the fifth of five 200' bore holes for the ground source heat pump system, which will heat and cool cottage #7.

After the hole is drilled, two one-inch diameter pipes - joined at the bottom - are placed in the hole. Bentonite, a type of clay, is then pumped down the hole to seal the pipes in place and ensure good conductivity with the earth. Lateral pipes will be added to join the five sets of vertical pipes in series. Once the system is complete, glycol will flow through the pipes to conduct the energy exchange. Ground source heat pumps are the most energy efficient way of heating and cooling a building.

The drilling rig is set to bore the three 200' foot holes that will be used in the ground source heat pump system for cottage #3.

Workers are applying roofing felt and rain guard material in preparation for the standing seam metal roof. The awnings are positioned to provide shading of the windows during the summer, but allow the light to enter the windows more fully in the winter. This assists with reducing the heating and cooling load of the building.
