At Pringle Creek Community we’ve been busy with several projects–cottage homes, Painter’s Hall, greenhouses, geo-thermal system, two new custom homes, and organizing our community gardens, as well as other endeavors. So much going on that we’ve neglected to keep up to date about it here on the “community news” page. We’ll get caught up right now and over the next few weeks.
Regarding Pringle Creek Community’s geo-thermal heating and cooling system, here, from the case study by Opsis Architecture, is a brief explanation:
A well designed for domestic water use and irrigation, located at the Pringle Creek site, has been utilized for a GPHS (ground source heat pump system) water distribution system. The well has a 280 gallon per minute capacity for delivering water at a 59 degree temperature. The GPHS district loop will extract the ambient earth temperature water from the production well pump and deliver the water to each lot via a supply piping system within the street right of way. At each lot, the water will be borrowed and circulated through a heat pump where the heat will be either extracted from the water in the heating mode, or rejected to the water in the cooling mode. After passing through the lot, the heat pump returns the water through a return piping system, where it either becomes available for irrigation use or it is returned to the aquifer via injection wells. Untilized by half the lots at Pringle Creek, the GPHS system is approximately 300% more efficient at delivering heat that a gas furnace.
