Rose Cottage maximizes comfort with radiant heating

The word cottage might evoke an image of an old, quaint little house that relies on antiquated methods, but the Rose Cottage is actually a state-of-the-art green residence. In fact, this 3,370-square-foot house utilized a remarkable construction method that results in net-zero-energy consumption and surprisingly low costs. The name has some significance as well: It stands for Renewable energy production, Owner-driven spatial design, Sustainable building practices and Energy-efficiency construction. The idea behind The ROSE Method is that each building and design project should be approached in an individual way, taking into account the unique environmental aspects of the location. By considering these aspects on a custom basis, every home can maximize comfort, health, energy efficiency and eco-friendly potential.An airtight home
According to TreeHugger, owner Harold Turner worked with his company H.L. Turner Group to design an abode in accordance with the passive house standards. These guidelines require that the home utilized an efficient integrated heating and cooling system, and additionally, has adequate insulation. This is especially important in New Hampshire, where the winters can be extremely frigid and the summers hot and humid. With double and triple insulated windows and materials like cellulose fibers, expanding polystyrene and mineral wool inside the roof, walls and floors, very little heat is able to leak out during the winter or summer. Such solid insulation combined with a radiant heating system means Turner's home is consistently the perfect temperature.An innovative system
So how does it work? Essentially, two geothermal pumps draw heat energy from underground. One of them is used to provide hot water, which is then used to emit warmth through the radiant floor heating system. The other tempers the air to cool the rooms when necessary in the summer. This eliminates the need to deal with two separate energy-intensive heating and air conditioning systems. Unlike some ground source heat pump systems, this one uses horizontal pipes inside a sand bed as opposed to traditional wells. Treehugger reported that the major focus for Turned was to design a house that his family could stay in for years to come, even as he grows old."I am particularly proud of the fact that we achieved our goal and managed to complete the building work in just over a year," Turner told BoschGlobal in an interview. "The end result is a net-zero-energy house whose architecture fits in with the picturesque surroundings here on the banks of the lake, and which is also very comfortable inside."
