A growing awareness of environmental problems and energy scarcity has led architects and engineers to reevaluate their approaches to building design. Three approaches to combining environmental control systems with design in the Department of Architecture at the University of Oregon are discussed. (MLW)

Much of the innovative work in the design and application of heating, ventilating, and air conditioning (HVAC) systems is concentrated on improving the cost effectiveness of such systems through optimizing energy use. One approach to the problem is to reduce a building's HVAC energy demands by designing it for lower heat gains and losses in the…
