ガラス建築群の将来予測モデルによるファサード熱性能に関する研究

摘要

1）空調部のガラス面積率43%以上の外壁面を1面以上有する建物rnを「ガラス建築」と定義した。計106物件の竣工図面調査を行っrnた。rn2）東京都のガラス建築のストック数は増加傾向にあるが，ダブルrnスキン等の高性能なファサードを導入した物件の割合は少なrnかった。%The purpose of this study was to calculate future energy consumption in case new improvement glass facade design is adopted. At fast, glass facade buildings in Tokyo were investigated through the use of the architectural magazines. Questionnaire was consisted of glass facade detail survey. Total energy consumption figure calculated from PAL simulated by a heat and air transfer system simulation program for building and from total glass area. If increasing rate of glass area was small and "PAL=200" and "Efficient heat source system" were innovated, energy consumption from glass facade buildings was below the 2008 value. It was understood that beefing up the current standards drastically and innovating the method of thermal high-performance design of building facade were needed.
