Residential HVAC

Issue of Residential HVAC Heating and cooling to maintain appropriate conditioning of indoor air consume a large portion of building energy use. Installing the right size equipment to heat and cool homes is essential to getting the best performance and comfort and reducing inefficiencies. A system that is too large will not keep the building comfortable because of frequent ‘on/off’ cycling. Incorrect sizing can also put stress on system components, shorten the equipment’s life, and lead to wa...

New Hampshire

new hamsphire
Background With small country farmhouses and snow-covered woods, New Hampshire evoked the idyllic New England imagery of Robert Frost, a longtime resident. Yet behind this scenic backdrop lay a modern state that was working hard to be a model for energy efficiency and renewables. New Hampshire’s per capita energy consumption was already the fifth lowest in the country, according to the Energy Information Administration, behind tiny Rhode Island and efficiency heavyweights New York, California...

Commercial Fenestration

commercial building
Issue As the primary barriers between indoor and out, the openings of the building envelope, high performance windows, doors, and skylights (fenestration) are essential to an energy efficient building. Choosing such products involves several considerations, including appearance, energy performance, human factor issues, technical performance, and cost. Other factors like building orientation, natural and artificial shading, and climate will influence the properties selected for windows, doors,...

Air Sealing

air sealing
Issue Inadequately sealed building envelopes can lead to the movement of unconditioned air into and out of conditioned spaces. This process, known as air leakage, decreases the comfort of a building by allowing moisture, drafts, and undesired noise to enter. It applies to any holes, cracks, or gaps in the building envelope. It is important to control air movement in buildings because research indicates that air leakage can cause huge energy losses, accounting for up to a third of a home’s ene...
