The Coastal Wind Initiative at the North Carolina Solar Center provides education and outreach on wind energy technology to communities in coastal North Carolina. The Wind Energy Intern will help with the development and delivery of the program’s outreach campaign, including assisting with public workshops, updating factsheets, and managing website content.
This, the fourth article in our series on green (sustainable) buildings focuses on the twin subjects of energy efficiency and water efficiency two fundamental areas of importance for green buildings. These are important not only because they reduce usage of and promote reuse of these precious resources, but because in so doing to minimize the building environmental impact. A well designed green building, can not only reduce its own environmental impact, but can improve a surrounding environment.
The White House announced that the U.S. Department of Energy Office of Science will invest $777 million in Energy Frontier Research Centers (EFRCs) over the next five years. In a national effort to accelerate scientific advances in critical areas of the new energy economy the United States Department of Energy (DOE) will establish 46 new multi-million dollar Energy Frontier Research Centers (or EFRCs) across the nation.
For new projects where the building site is not already decided, an important green consideration is the selection of a location for the building that fits into the existing urban fabric, especially the existing mass transit network of the city. Prospective sites should also be selected based on how easily they can integrate into the existing electric, gas, water, and sewage utilities. Fitting into a city’s existing infrastructure so that a project has the smallest impact on the existing energy, water, sewage and road systems is the first point at which the green decision making process comes into play. In addition to siting a green building should be oriented and landscaped to make the most of its site ant to integrate into the urban fabric so that it organically fits into it and enhances its surroundings. Orientation and landscaping can have major impacts on a buildings water and energy efficiency as well as on its environmental impact.
US Department of Energy Secretary Chu announced plans to provide nearly $800 million from the American Recovery and Reinvestment Act targeted towards advancing biofuels research and development and for commercial-scale biorefinery demonstration projects. The $786.5 million in Recovery Act funding a mix of new funding opportunities and additional funding for existing projects, will be allocated over four main areas. Integrated pilot- and demonstration-scale biorefineries projects are to receive the bulk of the funding with the remainder going to commercial-scale biorefinery projects, fundamental research in key areas to advance cutting-edge conversion technologies, including generating more desirable catalysts, fuel-producing microbes, and feedstocks and to ethanol research.
Many green buildings also seek to promote a green aesthetic and ambiance in their design and in how they are sited within the urban fabric they will exist within. Often these other additional design considerations flow from and are achieved in a synergistic manner by the structure’s other central design goals of reducing energy impact, water impact and providing a healthy inner space for its occupants. Sustainable buildings often promote a more livable environment and ambiance within and around them; enriching both the inner and the outer spaces.
This five part article series on green buildings (also known as sustainable buildings) attempts to answer the following fundamental question: What is meant when someone says “green building” — what exactly are they talking about? In short a green building, is one that is designed, built, renovated, and operated in a resource-efficient manner and that minimizes its environmental impact. It promotes: Energy efficiency, material efficiency, water efficiency and healthful building environment. And generally the term implies that the structure addresses all four of these principle aspects in one manner or another.
In this first post of the BIOFUEL UPDATE — a newly introduced feature of The Green Economy Post — I write about how so called first generation Biofuels such as Corn Ethanol that are derived from food crops or grown on land that otherwise would be used for food crops may be worse for global warming than burning gasoline is! This reconfirms in my mind the pressing need for the biofuel sector to move towards non-food biofuel crops that also are grown on marginal land; crops such as algae, switchgrass, jatropha etc. In other news the Danforth Science Center in Saint Ls. MO gets $15 million in federal funds. Fedex announces plans to get 30% of its fuel from second generation non-food crop biofuels by 2030. OriginOil has developed a simpler and more efficient way to extract oil from algae.
Can Off-peak Air Conditioning (OPAC) technology, improve the green energy profile of data centers? One of the major energy consumption categories of data centers is their need to keep all of their rows of rack mounted servers operating within their critical temperature parameters. Many various techniques are increasingly being adopted by data centers around the world in order to lower their overall cooling needs. An additional technology exists that I believe can help data centers improve their energy usage profiles by shifting energy demand to off-peak hours and in so doing significantly lower their energy consumption during critical periods of peak demand. Off-peak Air Conditioning (OPAC) technology is a way for data centers to improve their peak energy demand profile.
