LEED Delivers on Predicted Energy Savings
December 6, 2007 10:13 AM - 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. 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.
Scottish government to review Trump plans
December 4, 2007 03:13 PM - Andrew Hough, Reuters
LONDON (Reuters) - The Scottish government said on Tuesday it would review controversial plans by U.S. tycoon Donald Trump to build a $2 billion golfing development in Scotland after they were rejected by the local council.
It said it was intervening because the project, to build two championship golf courses, around 1,000 homes, a luxury hotel and 36 villas on a pristine stretch of northeast Scotland's coast, was too "important" to be dealt with by the council.

PORTLAND - Residents began this week moving into The Casey condominiums, on track to be the first multifamily residential building in the United States to receive LEED Platinum certification, the highest level of green building.
The Casey is a 16-story building with 61 luxury homes in the heart of Portland's Pearl District, steps from art galleries, restaurants and boutiques. The building incorporates a comprehensive array of sustainable features including solar panels, a green roof and the extensive use of recycled-content and sustainable materials such as wool carpets and FSC-certified wood flooring. It also has a host of energy efficiency features including sophisticated waste heat recovery ventilators in each unit that help the building achieve a 52 percent energy savings over code.

PHILADELPHIA, PA – Buyers beware - that so-called “Green” product is likely stretching the eco-truth according to the Six Sins of Greenwashing, a study released today by TerraChoice Environmental Marketing.
The Six Sins of Greenwashing found that of 1,018 common consumer products ranging from toothpaste to caulking to shampoo to printers, randomly surveyed for the study, 99% were guilty of “greenwashing.”
Chicago’s Alleys Turning Green
December 3, 2007 09:09 AM - Alana Herro, Worldwatch Institute
A new initiative will help make Chicago’s 1,900 miles (3,000 kilometers) of alleyways more sustainable. The miniature streets behind homes and buildings, used mainly for garbage collection and parking access, keep main roads cleaner and less congested but are prone to flooding. The city’s innovative Green Alley Program promotes improved construction techniques and materials that can improve drainage, reduce runoff, and relieve strain on the city’s aging sewer system.

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.
Clinton Library Earns LEED Platinum

The US Green Building Council (USGBC) announced last week during Greenbuild that the William J Clinton Presidential Library has earned Platinum Certification under the LEED for Existing Buildings (LEED-EB) Rating System. President Clinton received the certification plaque from USGBC CEO Rick Fedrizzi. This certification recognizes that the Clinton Library in Little Rock, Arkansas, has implemented a continuous sustainability improvement process guided by LEED-EB. Leonardo Academy was the primary LEED consultant for this project, supporting the successful implementation of LEED-EB and advancing the Library’s LEED rating from the Silver Certification earned under LEED for New Construction (LEED-NC) to the Platinum Certification earned under LEED-EB.
Grand Hyatt Dubai Opts for Solar Power to Reduce Costs, Climate Impact
November 15, 2007 09:43 AM - , Green Lodging News
DUBAI, U.A.E.—The Grand Hyatt Dubai has converted its main water heating system from diesel oil-fired to solar powered in a bid to reduce climate change and running costs. With the UAE’s carbon footprint spiraling, causing the country to be one of the largest emitters of carbon dioxide per capita in the world, the Grand Hyatt Dubai’s new solar panel heating system will reduce its own emissions dramatically.
