The Passive House concept is being actively implemented in Portland.

The method’s popularity among builders and architects is rising as the industry seeks to accomplish ambitious goals to cut energy use.

Passive House, a German-born design-build method, uses an airtight building envelope and advanced energy calculation software to create a building that uses 90 percent less energy than a standard home.

New Carbon Monoxide Rules Take Effect April 1, 2011

In 2009, Oregon Legislature passed HB 3450, also known as the Lofgren and Zander Memorial Act, requiring the installation of carbon monoxide alarms in specific residential applications with a carbon monoxide source. The rules began to take effect on July 1, 2010.

Carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, charcoal, coal, natural gas, propane, oil, kerosene, and methane) burn incompletely. Products and equipment powered by internal combustion engines also produce carbon monoxide. Fumes are dangerous and can be deadly.

New "Fuel Mileage" Label for homes

Energy Trust of Oregon has developed a new residential energy labeling system that allows buyers to compare the efficiency of homes in the same way that consumers compare the fuel efficiency of automobiles. Based on considerations such as a home’s size, level of insulation, HVACHeating, Ventilating and Air Conditioning. systems, lighting, and major appliances, the Energy Performance Score is calculated based on both energy consumption and carbon emissions, with low scores indicating the greatest efficiency.

Portland had 80 Energy Star buildings in 2009, when it ranked 12th on the EPA list.
