Displacement ventilation (DV) units use the natural buoyancy of warm air to improve ventilation and comfort. Although relatively new to the United States, DV has been used in Scandinavian countries since the 1970s. Two types of DV can be used in a classroom: (1) Conventional displacement ventilation (CDV) units which are situated on an interior…

Roofs always have been a major focus for building energy-conservation measures. The emphasis traditionally has been on beefing up insulation. More recently, advances in roofing materials technology and analytical techniques have found new ways to fine-tune the energy performance of roofing to reduce not only operating costs, but also environmental…

From around the corner to around the nation, schools and universities are looking to reduce their energy bills. Some are concerned about fuel costs and the impact on their operating budgets; others are motivated by the desire to reduce their carbon footprints and their impacts on the environment. Professionally installed window film can play a key…

Describes the design of the expansion of the National Center for Supercomputing Applications (NCSA) Advanced Computation Building at the University of Illinois, Champaign. Discusses how the design incorporated column-free space for flexibility, cooling capacity, a freight elevator, and a 6-foot raised access floor to neatly house airflow, wiring,…

Discusses issues addressed by OCLC in the construction of its new headquarters. Original design criteria and a retrospective appraisal of solutions are presented in the following areas: (1) structural requirements; (2) environmental considerations; (3) utilities; (4) fire protection; (5) security; and (6) workspace design. Essential design issues…

In this article, the author discusses the role of window films in enhancing indoor air quality in schools. Historically, window film has been used to reduce temperatures in buildings prone to overheating. Too much solar energy entering through windows makes occupants uncomfortable and air conditioning more costly. Film has been a simple solution…

Amid climbing energy costs and tightening budgets, administrators at school districts, colleges and universities are looking for all avenues of potential savings while promoting sustainable communities. Cool metal roofing can save schools money and promote sustainable design at the same time. Cool metal roofing keeps the sun's heat from collecting…

This publication is the design development presentation for an energy-conserving elementary school building proposed for Alief, Texas. Some of the energy conservation features presented in this proposal include: (1) wind powered emergency electrical system; (2) complete insulation resulting in a building with an over-all U factor of .04; (3) air…
