Radiant Energy System in West Bristol School
Project at a Glance
West Bristol School was looking to build a school that would reduce energy costs and be green building certified. Like all Connecticut schools, they are mandated to be build to LEED Silver status. LEED (Leadership in Energy and Environmental Design) is an internationally recognized green building certification system, and Silver is the third highest of its four designations.
We designed a system using geothermal technology that required 150 wells to be dug at a depth of about 500 feet. The classroom floors have radiant heat that brings warmth to the students’ feet, and cool air is brought in through vents near the ceilings. By bringing the warmer temperatures in from the floor and cooler temperatures from the ceiling, the system works at its optimum and most efficient design.
The system required more than 75,000 feet of pipe, and water is pumped through Wirsbo hePEXTM tubing from deep in the earth, where the ambient temperature is always 52oF (11oC). During warm weather the water will be cooled down and in the winter it will warm up. There are no boilers and the water is heated through heat transfer pumps and then circulated through the buildings.
