A building envelope is the physical separator between the conditioned and unconditioned environment of a building including the resistance to air, water, heat,〔Cleveland, Cutler J., and Christopher G. Morris. "Building envelopergy''. Expanded Edition. Burlington: Elsevier, 2009. Print.〕 light, and noise〔Syed, Asif. ''Advanced building technologies for sustainability''. Hoboken, N.J.: John Wiley & Sons, Inc., 2012. 115. Print.〕 transfer. ==Discussion== The building envelope is all of the elements of the outer shell that maintain a dry, heated, or cooled indoor environment and facilitate its climate control. Building envelope design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control.〔 The many functions of the building envelope can be separated into three categories:〔Straube, J.F., Burnett, E.F.P. ''Building Science for Building Enclosures''. Building Science Press, Westford, 2005.〕 * Support (to resist and transfer mechanical loads) * Control (the flow of matter and energy of all types) * Finish (to meet human desires on the inside and outside) The control function is at the core of good performance, and in practice focuses, in order of importance, on rain control, air control, heat control, and vapor control.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Building envelope」の詳細全文を読む スポンサード リンク
