IPCC Looks To Building Sector For Cutting C02 Fastest
December 21, 2007 03:33 PM - Nadav Malin , BuildingGreen

On November 17, 2007 the Intergovernmental Panel on Climate Change (IPCC) released its fourth “Synthesis Report” along with a “Summary for Policymakers.” The latest report integrates the findings of reports released earlier in 2007 by each of the three IPCC working groups, which dealt, respectively, with the underlying science of climate change, the likely impacts, and mitigation options.

Homes Get Their Own LEED
December 21, 2007 03:23 PM - Allyson Wendt, BuildingGreen

When the U.S. Green Building Council (USGBC) first rolled out the LEED for Homes rating system pilot in 2005, it faced a number of challenges, including creating a provider network, training raters, keeping registration and certification fees low, and convincing homebuilders and homeowners that certification was worth the expense.

Kansas Town Rebuilding as the Greenest in America
December 21, 2007 03:08 PM - Rachel Navaro, BuildingGreen

On May 4, 2007, a two-mile-wide tornado ripped through Greensburg, Kansas, demolishing 90% of the small town’s structures. Within a week, nearby resident Daniel Wallach founded Greensburg GreenTown (GBGT). Its mission is to provide the residents of Greensburg with the resources, information, and support they need to rebuild as “the greenest town in America.”

LEED Delivers on Predicted Energy Savings
December 21, 2007 02:57 PM - Nadav Malin , BuildingGreen

LEED Delivers on Predicted Energy Savings With its dominant position defining green building in the North American market, the LEED Rating System is a popular target for critics with a wide range of axes to grind, some justified, others less so. One of the more valid concerns is that LEED’s promises of energy savings (and therefore carbon reductions) are just that—promises.

Sustainable Urbanism
December 21, 2007 02:51 PM - Rachel Navaro , BuildingGreen

Combine walkable, transit-served urbanism with high-performance building and infrastructure and, according to author Douglas Farr, AIA, you’ve got Sustainable Urbanism. Beyond just developing a concept, however, the book acts as a comprehensive how-to manual for anyone who helps shape the built environment, from architects to mayors, planners to neighborhood groups.

Energy Metrics: Btus, Watts, and Kilowatt-Hours
December 21, 2007 02:45 PM - , BuildingGreen

Nearly every green publication (including, unfortunately, our own) has, on occasion, confused units of electric power (kilowatts) with units of energy (kilowatt-hours). It’s an easy mistake to make for those who are not steeped in the engineering of energy flows. But the basic principles are not that complicated—and are worth getting straight.

LEED Delivers on Predicted Energy Savings

LEED Delivers on Predicted Energy Savings With its dominant position defining green building in the North American market, the LEED Rating System is a popular target for critics with a wide range of axes to grind, some justified, others less so. One of the more valid concerns is that LEED’s promises of energy savings (and therefore carbon reductions) are just that—promises. With the exception of LEED for Existing Buildings, which looks at actual operations, LEED’s various rating systems assign energy points to buildings based on predictions made during design. How well those predictions hold up in reality has, until now, been subject to conjecture.

Thermal Mass: What It Is and When It Improves Comfort
November 28, 2007 09:13 AM - , BuildingGreen

Heavy or massive objects like masonry, earth, and water can hold a lot of heat. Because of this capacity to act as a heat source (warming their surroundings) or a heat sink (drawing heat from and cooling their surroundings), materials with thermal mass affect comfort both indoors and out. (Oceans and lakes, for example, moderate air temperature changes because their thermal mass acts as a buffer.)

Buildings in climates with large diurnal (day-night) temperature swings, like the high-elevation Southwest, offer a classic example of the time-lag effect of thermal mass. Adobe and other types of masonry walls absorb intense daytime heat, keeping temperatures comfortable inside. During the cold night, the walls pour out their accumulated heat, keeping the inside warm. By morning the walls, if they are designed correctly, can again absorb the daytime heat.

California Fire Codes Put Focus on Plastic Decking Concerns
November 5, 2007 11:15 AM - Stan Korthals Altes , BuildingGreen

A highly publicized series of wildfires has struck California in the last decade, putting a focus on homes in wildfire-prone areas and the flammable materials they are constructed from—including roofing, siding, and decking. Taking effect on January 1, 2008, the Wildland-Urban Interface Building Codes, developed by the California Office of the State Fire Marshal (SFM), aim to protect homes and the safety of occupants and firefighters. Among other provisions, the codes restrict relatively flammable decking, including wood-plastic composites.

The new codes affect “Fire Hazard Severity Zones,” identified by topography (fire spreads faster on slopes), vegetation that fuels fires, weather patterns, history of past wildfires, and likelihood of fire spreading from neighboring areas. Those zones affect a significant portion of the state, mostly in rural areas, but they also frequently intersect with populated areas. According to Kevin Reinertson at SFM, the standards have been projected to affect 8%–11% of new construction in California.

 

Wisconsin Leopold Center Earns LEED Platinum
November 5, 2007 11:04 AM - , BuildingGreen

Baraboo, Wisconsin -  Built in honor of one of the world’s most famed conservationists, the Aldo Leopold Legacy Center, located on Leopold’s farm near Baraboo, Wisconsin, has earned 61 out of a possible 69 LEED points, the most earned by any LEED-certified building to date and enough to qualify for a Platinum rating.

The net-zero-energy building produces as much energy as it consumes with a grid-tied photovoltaic system and a ground-source heat pump serving a radiant-floor heating system; wood stoves add additional heat.
