Here’s a low carbon cooling technology that uses hot water from waste to make A/C without fossil fuels, saving 80% over fossil-fueled chillers.

This industrial scale chiller from the Chinese company Broad Central Air can convert many different kinds of waste heat into air conditioning. The waste heat can come from many industrial sources, including what the Chinese site calls “town gas”  - methane from town landfill, collected and burned to generate heat.

From the outside, the Comfort Inn La Estancia near San Diego looks like your garden variety mainstream hotel, complete with free parking for truckers and RV’s.  But soon it will share something sustainable that many boutique “green” hotels boast, 100% solar power for its electricity usage.

The greening of Comfort Inn is thanks to a partnership with Pursol Solar Systems, which will install an 83 kilowatt photovoltaic system under its Solarize financing program, basically guaranteeing the hotel a 20% savings on its electricity bill without any up-front costs.

Solar Decathlon 2009: The Construction Site

The solar capacity of the National Mall in Washington D.C. has increased exponentially in just a week as teams of college students from 20 international schools hurriedly reassembled their submissions for the fourth ever Solar Decathlon, a competition in which students must create “the most attractive, effective, and energy-efficient solar-powered house.” The three-week event kicked of yesterday with an opening ceremony that featured a speech from Energy Secretary Steven Chu, who

The California Public Utilities Commission has approved the largest energy efficiency program in U.S. history, authorizing $3.1 billion in consumer rebates and efficiency programs over the next three years. This brings the state a giant step closer to implementing AB32, according to Lara Ettenson, director of California Energy Efficiency Policy at the NRDC.

Ettenson told me that the funding comes from the part of the budget that California’s regulated utilities may use to invest in conventional electricity. This may include “negawatts” [...]

Global Solar Center just finished a comprehensive, 50-state survey of solar incentives and adoption. Who leads the nation? It is surprising. As they say, it is the states who were “solar laggards” that are now “solar leaders”. But incentives aren’t the only issue.

In the quest to create new green jobs, we have the opportunity to take existing jobs and make them green.

Every city has architects, engineers and construction divisions. In conventional circumstances the activities these employees undertake can burn considerable natural resources. But in San Francisco, we’re working to turn these traditional municipal positions into environmental champions.

Under recommendations from the UK Green Building Council, otters could return to urban rivers, bats could roost under bridges, swifts could flock to office blocks and peregrine falcons soar above cathedrals. Written by Felicity Carus and shared via the Guardian Environment Network.

What do the Westfield shopping centre, Canary Wharf and a Victorian museum have in common? They are all at the vanguard of a move to encourage biodiversity in buildings that could take on an unprecedented scale if guidelines published today are adopted.

A groundbreaking study has proved that man-made light sources can change natural light cycles, triggering abnormal animal behavior that often leads to injury and even death.

The study, published in the journal Frontiers in Ecology and the Environment, confirms that polarized light pollution can cause confusion in creatures that rely on light ‘cues’ to navigate through their environment, with many animals also thrown off course by light reflecting from buildings.

Buildings, according to calculations done by Architecture 2030, are responsible for nearly half of the total energy consumption in the United States. And 76 percent of the electricity generated in this country goes to the Building Sector. So while there are a range of steps that need to be taken in moving toward a more sustainable lifestyle, Buildings, and the energy they consume, need to be at the forefront of any considerations when moving toward greater sustainability.

Saving energy in buildings is both one of the easiest things that can be done, as well as one of the hardest. The principles for creating a building that needs less energy and operates more efficiently are well known. Most building technology is fairly basic and easy for even non-experts to understand. This makes it simple. We don’t have to wait for expensive, high tech solutions (though they can contribute greatly and will provide new flexibility and compelling possibilities for building better buildings in the future). Heavily insulated buildings can be easily constructed with readily available and well known technology. Adding more insulation to walls is easy, though there is a cost. Consumers and building owners need to become more aware of the long term costs of operating a building, and give consideration to more than just the initial construction costs. And overcoming economic considerations and taking a long-term view is the hard part.

The city of the future is not going to be a Jetson-esque collection of bubbles in the air, or towers connected by monorails, or any other radical vision. The city of the future will be more like that in Blade Runner, mostly recognizably familiar older buildings. Most of the city of the future has already been built and is standing. Certainly new buildings will
