LED (light-emitting diode) technology is moving fast, and with justification, some facility managers have viewed it with a wary eye. Some LEDs on the market do not perform as promised, and the technology is changing rapidly. But new developments from the U.S. Department of Energy (DOE) now make it easier for facility managers to find LEDs that…

When one considers the enormous cost of science laboratory buildings, it is no surprise that the stream of environmental consciousness that has swept through campuses has had a profound effect on the design and engineering of these complex buildings. Advancing technologies, government regulations and rising energy costs all are driving the push to…

Climate change, rising energy costs, and other dilemmas raise the prospect for major change in energy-ecology-society relations. Two prominent proposals for change include: a nuclear power renaissance; and mega-scale renewable energy development. Both suggest that modern society will receive a rising stream of less CO2-rich kilowatt-hours, so that…

By making a commitment to high-performance schools, many school districts are discovering that smart energy choices can have lasting benefits for their students, their communities, and the environment. An energy-efficient school district with 4,000 students could save as much as $160,000 a year in energy costs. Over 10 years, those savings can…

Energy costs are projected to rise as much as 12 percent in 2008, and a facility's "carbon footprint" has become an issue of increasing importance. So, many schools and universities are taking a hard look at their energy consumption. Education facilities can save tens of thousands of dollars in yearly electric costs, and cut harmful emissions by…

In 2008, APPA forwarded a Web-based survey on the author's behalf to all designated representatives of APPA member institutions. The purpose of the survey was to determine if institutional policies are an important criterion for an institution's sustainable building practices and the use of Leadership in Energy and Environmental Design (LEED[R]).…

Like most school districts across the country, the Virginia Beach City Public Schools (VBCPS) leaves a large environmental footprint in the community. That's why about eight years ago, the VBCPS began to look at how the district could transition toward a more sustainable model. The objective was simple: Be part of the solution, not part of the…

Lured by the recognition that comes with a Leadership in Energy and Environmental Design (LEED) rating from the U.S. Green Building Council, many schools and universities have become aware of that certification process. But for years, the involvement was limited to a few trendsetters; according to the Green Building Council's database, only about…

This article presents a study of the techno-economical feasibility of manufacturing biofuel ethanol at small scale from agricultural sources in New Zealand. It investigates possible agricultural products and wastes as potential feedstock and looks at laboratory-scale fermentation trials to determine their ethanol yields. The ethanol requirement to…

Since the mid-1980s, power sector liberalization has been embraced at different levels in the East Asian countries of China, Japan, South Korea and Taiwan. The dominant rationale underlying power liberalization has been a quest for efficiency improvements, to be achieved by substituting private market activity for public regulations and by opening…

The guide allows users to adapt and implement suggested O&M (operating and maintaining) strategies to address specific energy efficiency goals. It recognizes and expands on existing tools and resources that are widely used throughout the high-performance school industry. The guide is organized into the following sections: (1) Chapter 1:…

The University of Maine at Farmington (UMF) has undertaken a commitment to establish a culture of environmental sustainability. With two new Leadership in Energy and Environmental Design (LEED) certified buildings on site, a green building curriculum has been developed. This multidimensional curriculum involves university faculty, students, K-12…

Energy use in Iceland (population 283,000) is higher per capita than in any other country in the world. Some 53.2% of the energy is geothermal, which supplies electricity as well as heated water to swimming pools, fish farms, snow melting, greenhouses, and space heating. The Nesjavellir Power Plant is a major geothermal facility, supplying both…

More colleges are making sustainability programs a high priority, putting more resources into energy-conservation efforts, and setting goals to reduce carbon emissions, according to survey results released by the National Wildlife Federation. Given the popularity of all things green, that is not surprising. The surprising part of the federation's…

This article discusses Hawaii's energy conservation efforts. Faced with high electricity costs, the Hawaii Department of Education instituted a pilot program in which schools could earn back half the amount they saved in electricity over the course of a semester. As a result, one school's electricity use decreased by more than 10% for the…
