The National Renewable Energy Laboratory Visitors Center, also known as the Dan Schaefer Federal Building, is a high-performance building located in Golden, Colorado. The 6,400-square-foot building incorporates passive solar heating, energy-efficient lighting, an evaporative cooling system, and other technologies to minimize energy costs and environmental impact. The Visitors Center displays a variety of interactive exhibits on energy efficiency and renewable energy, and the building includes an auditorium, a public reading room, and office space.

This booklet is designed to guide you through the process of buying a grid-tied solar electric system. A word of caution: This is not a technical guide for designing or installing your system.

This document provides an overview of the U.S. Department of Energy's Building America program. Building America works with the residential building industry to develop and implement innovative building processes and technologies-innovations that save builders and homeowners millions of dollars in construction and energy costs. This industry-led, cost-shared partnership program aims to reduce energy use by 50% and reduce construction time and waste, improve indoor air quality and comfort, encourage a systems engineering approach for design and construction of new homes, and accelerate the development and adoption of high performance in production housing.

The New American Home{reg_sign} is an annual showcase project designed by committee and co-sponsored by the National Association of Home Builders' National Council of the Housing Industry, BUILDERS Magazine, and Ladies Home Journal. Hedgewood Properties teamed with Building America's IBACOS Consortium and Southface Energy Institute to build a house with a Home Energy Rating Systems (HERS) level of 90.

Consumers in Pennsylvania, Virginia, Delaware, Maryland, the District of Columbia, West Virginia, and New Jersey are showing increased interest in solar electric systems for their homes and businesses. This booklet provides basic information about buying a PV system. Photovoltaic (PV) systems are reliable, pollution free, and use a renewable source of energy--the sun. A PV system can be a substantial investment and careful planning will help ensure that you make the right decisions.

The toxigenic strains of Clostridium botulinum produce seven serologically distinct types of neurotoxins labeled A - G (EC 3.4.24.69), while Clostridium tetani produces tetanus neurotoxin (EC 3.4.24.68). Botulinum and tetanus neurotoxins (BoNTs and TeNT) are produced as single inactive chains of molecular mass of approximately 150 kDa. Most of these neurotoxins are released after being cleaved into two chains, a heavy chain (HI) of 100 kDa and a light chain (L) of 50 kDa held together by an interchain disulfide bond, by tissue proteinases. BoNT/E is released as a single chain but cleaved by host proteinases [1]. Clostvidium botulinum neurotoxins are extremely poisonous proteins with their LD{sub 50} for humans in the range of 0.1 - 1 ng kg{sup -1} [2]. Botulinum neurotoxins are responsible for neuroparalytic syndromes of botulism characterized by serious neurological disorders and flaccid paralysis. BoNTs block the release of acetylcholine at the neuromuscular junction causing flaccid paralysis while TeNT blocks the release of neurotransmitters like glycine and {gamma}-aminobutyric acid (GABA) in the inhibitory interneurons of the spinal cord resulting in spastic paralysis. In spite of different clinical symptoms, their aetiological agents intoxicate neuronal cells in the same way and these toxins have similar structural organization [3].

This guidebook has been prepared primarily for Federal energy managers to provide practical information for applying the principles of low-energy, whole-building design in new Federal buildings. An important objective of this guidebook is to teach energy managers how to be advocates for renewable energy and energy-efficient technologies, and how to apply specific strategies during each phase of a given project's time line. These key action items are broken out by phase and appear in abbreviated form in this guidebook.
