前言近世的建筑设计都有考虑省能措施,甚而曾可见到许多以省能为主的所谓省能建筑实例。其原因是社会需求决定了省能的重要性。此外由于能源费用高涨也促使设计上重视省能。但是过去设计建成的旧有建筑却大多忽视省能设计。以办公楼为例,若按空调、照明等不同用途划分的一次能源消耗量,则大致如表1 Preface Modern architectural design has considered energy-saving measures, and even many examples of so-called energy-efficient buildings featuring energy-saving can be seen. The reason is that social needs determine the importance of saving energy. In addition, due to the high cost of energy also contributed to the design of energy-saving. However, most of the old buildings built in the past have largely ignored energy-saving design. To office buildings, for example, if according to air conditioning, lighting and other purposes divided by the primary energy consumption, roughly as shown in Table 1
