在美国能源革新建筑计划部领导下的橡树岭国家研究所进行了一次地上与地下建筑的比较。这份研究是在降低建筑造价的舆论影响下,或者说在较高的初始造价可在短期内挽回的舆论影响下,为地下住宅所作的。早在70年代,我们就注意到了对地下建筑日益增长的兴趣。当时只有少数这样的建筑在1972年被报道过,而在1981年的《地下建筑设计和能源报告》的资料中就记载了近2500例地 The Oak Ridge National Institute under the leadership of the U.S. Department of Energy Innovation and Architecture Planning conducted a comparison between ground and underground structures. This study was conducted under the influence of public opinion that reduced the construction cost, or under the influence of the public opinion that the higher initial cost could be recovered in the short term. As early as the 1970s, we noticed a growing interest in underground construction. At that time, only a few of these buildings were reported in 1972, and in the 1981 “Architecture of Underground Buildings and Energy Reports”, nearly 2,500 sites were recorded.
