One of the interesting facets of the the NIST Net Zero home will be the ability for the researchers to test the performance of three closed-loop geothermal piping configurations; vertical, standard horizontal trench, and horizontal slinky loop piping.
Yesterday, our well drilling subcontractor, Easterday Well and Pump, began excavation for the slinky loop section. These loops will be installed in the front yard of the home, seen on the Site Plan on the south side of the home. Click the image to view a full sized PDF of the plan.
The standard horizontal trench is shown to the north of the home, while the three vertical wells will be be on the west side. NIST will be placing sensors in and around the slinky loops, to monitor earth temperatures.
Check back in a week for photos of the slinky loops installed.
