Climate Automation Systems manages radiant heat flooring, HVAC to bring lower costs, energy use to homes with large-scale commercial solution.

BOZEMAN, Mont. - It’s not just the major home mechanical systems that impact overall building efficiency. The accessories, like IAQ and controls products, can have a major impact on both comfort and efficiency - things that the contractors of 2010 are eager to address for their customers - due to their interaction with the main system. In fact, advanced applications like this one may point to bold new directions for the residential construction industry. Rehau recently announced the official groundbreaking for the Rehau Montana ecosmart house in Bozeman...

Mark Eatherton "I have often said that a radiant wall will deliver more radiant energy to a human body than will a horizontal ceiling or floor surface. Think of absorbing radiant energy like a flash light beam. The more energy you intercept of the flash light beam, the larger the shadow, thus, the more energy you intercept and the more warmth you feel."

Nelson Mechanical Design (NMD) has a long-standing reputation for being a green contractor, and it goes beyond the steps many HVAC contractors are taking now, well intentioned though they may be. That’s because NMD has been a trailblazer, pushed in part by the progressive customers on Martha’s Vineyard.

This residence, overlooking the Vineyard Sound and coast of Massachusetts, is Martha’s Vineyard’s first LEED for Homes project.

A ten ton closed loop horizontal geothermal field serves five water to air heat pumps (five forced air zones) and one water to water heat pump (three radiant floor warming zones and domestic hot water preheat). Individual loops in the field were increased in size to minimize pumping energy. The entire geothermal system uses one Grundfos circulator with a built-in pressure sensor to optimize pumping energy.
