Window Solar Control (Spring 2002) IPRO 330: Window_Solar_Control_IPRO330_Spring2002_Final_Presentation

The Community Energy Cooperative is sponsoring a product development effort to create high performance window awnings. The overall objective is to develop a simple, low-cost easy-to-install, effective and pleasing exterior window solar control. Available products that reduce window solar heat gain range from reflective shades to new windows with low-emittance glass. In some cases, such as reflective film directly applied to glass, a 70 percent reduction in solar heat is possible. In general, however, no current product meets the full range of desired objectives. Objectives of a new awning design include: (1) inexpensive; (2) preserve window egress and ventilation functions; (3) permanently installed; (3) substantial cooling load reduction; (4) does not reduce solar heat in winter; (5) enhances daylight brightness, distribution within room and light quality; (6) minimal reduction in view; and (7) little (or favorable) influence on building appearance. A general concept for a new type of window solar control product has been envisioned by the Community Energy Cooperative. It is the purpose of the IPRO team over a two-semester period to refine the design concept, fabricate a prototype, demonstrate its effectiveness, assure its cost effectiveness and plan for its commercialization. The sequence of work will include literature search, modeling, design, building a prototype, and other activities leading to a production franchise agreement. Additional project tasks would include computer-simulation and field measurement of air conditioning and lighting performance change associated with awnings. This Project will add to the body of scholarly work on building energy performance and windows. The Community Energy Cooperative will make available various resources, including focus groups and contacts with product users, software and locations for test installations. The project will establish a format for community-based energy efforts that partner with colleges and universities.Sponsorship: Community Energy CooperativeProject Plan for IPRO 330: Window Solar Energy for the Spring 2002 semeste
