美国能源部现正在田纳西州的橡树岭国家试验室(ORNL OaK Ridge National Laboratory)建造美国独一无二的设施——屋面研究中心,以研究与低坡度屋面热效能以及耐久性有关的问题。此项目的重点是建造一个环境试验室。该环境试验室中,可在模拟气候条件下或是精心控制的各种参数变化之下,测试规模较大的屋面部分。屋面研究中心可供全美国使用,由橡树岭 The U.S. Department of Energy is currently building a U.S.-unique facility, the Roof Research Center, at the ORNL OaK Ridge National Laboratory in Tennessee to study issues related to thermal efficiency and durability of low-slope roofs. The focus of this project is to build an environmental laboratory. In this environmental laboratory, larger roof sections can be tested under simulated climate conditions or with carefully controlled changes in various parameters. The Roof Research Center is available throughout the United States and is managed by Oak Ridge
