DEPEW, NY — Builder David Lanfear is completing work on a 1,300-square-foot straw-bale house designed to approach net-zero-energy performance. Topped with a 10-inch-thick SIP roof, the home includes a 2-kW photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. array and an eight-tube evacuated-tube solar collectorSolar collector consisting of a series of glass vacuum tubes in which an inner tube containing fluid (or in some types, a metal plate) absorbs heat energy and transfers it for practical use, usually water heating. connected to an 80-gallon solar storage tank. “We’re using a lot of used and reclaimed lumber and we’re not using adhesives with VOCsVolatile organic compound. An organic compound that evaporates readily into the atmosphere; as defined by the U.S. Environmental Protection Agency, VOCs are organic compounds that volatize and then become involved in photochemical smog production.,” said homeowner Carrie Zaenglein. “We’re trying to do everything as green as possible.”

U.K. House Generates More Energy Than It Uses

Posted on January 6, 2009 by Martin Holladay

Insulation and Airtightness Are Key in Reducing Energy Use.

CLAPHAM, UNITED KINGDOM — Owner-builder Will Anderson claims that the house he completed in 2006 produces more energy than it uses. Equipped with a 4.3-kW photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. array, Anderson’s all-electric home is heated by a ground-source heat pumpHome heating and cooling system that relies on the mass of the earth as the heat source and heat sink. Temperatures underground are relatively constant. Using a ground-source heat pump, heat from fluid circulated through an underground loop is transferred to and/or from the home through a heat exchanger. The energy performance of ground-source heat pumps is usually better than that of air-source heat pumps; ground-source heat pumps also perform better over a wider range of above-ground temperatures.. The heat pump also supplies a portion of the home's hot water, with the remainder supplied by a solar thermal system.

Michigan Court Rules In Favor Of New Energy Code

Posted on January 5, 2009 by Martin Holladay

Homebuilders' Association Loses, Environment Wins

LANSING, MI — The Ingham County [Michigan] Circuit Court has ruled in favor of the state of Michigan, dismissing a challenge from the Michigan Association of Home Builders (MAHB) that sought to prevent energy-efficiency requirements for new homes. According to the Midwest Energy Efficiency Alliance (MEEA), “The new, energy-efficient code, adopted in 2004, had been in limbo due to legal maneuvering by the MAHB, which used the state’s legal system to circumvent the comprehensive administrative process that led to the adoption of a new, more energy efficient code. As a result, Michigan residents lost years of potential energy savings, totaling tens of millions of dollars and contributing to increased releases of environmental pollutants.”
