Department of Energy has sponsored a research program organized to improve energy efficiency in industrialized housing. Two research centers share responsibility for the Energy Efficient Industrialized Housing (BEIH) program: the Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. Additional funding for the program is provided by non-DOE participants from private industry, state governments and utilities. The program is guided by a steering committee composed of industry and government representatives. Industrialization of U.S. housing production varies from mobile home builders who ship furnished houses to the site, to production builders who assemble factory produced components on the site. Such housing can be divided into four major categories: HUD code (mobile) homes, modular houses, panelized houses, and production built houses. There are many hybrids of these categories. The goal of the Energy Efficient Industrialized Housing research project is to develop techniques to produce marketable industrialized housing that is 25% more energy efficient than required by today's most stringent U.S. residential codes, yet less costly than present homes. One aspect of the EEIH project is testing the energy performance of houses at several stages from design through occupancy. The activity described here comprises part of Task 2.6, "Tests of Construction Methods, Products, and Materials," a process which involves both field and laboratory studies. Toward this end the project will use the low speed boundary layer wind tunnel to study building ventilation and microclimates. This report describes progress toward the calibration of this instrument. First is a description of the tunnel itself -- a duct roughly 60 feet long, coupled to a variable speed fan, and shaped to provide a smooth air flow with minimum background turbulence. During calibration this level of turbulence was examined using the tunnel's three-part set of instruments: anemometry sensors (TSI Model 1066) and electronics, data acquisition system (IDAC-1000 plus custom communication program), and controlling Macintosh computer.Articleen-USIndustrial housing -- Energy conservationWind tunnelsBuildings -- Energy conservationArticle
