建筑中的固化能耗

分析了建筑中能耗由运行能耗，固化能耗两部分组成；固化能耗的具体含义以及研究固化能耗的意义；提出固化能耗的测定的不准确性。这种不准确性来源于三个方面：1.固化能耗的隐蔽性；2．固化能耗测定的长期性；3．固化能耗的界定范围可变性。然而，固化能耗的量化并不要求得出“正确”或“准确”的数字，量化的意义在于通过不同材料固化能耗的比较给建筑师选择材料时提供一个科学化的依据。最后，提供了一些常用建材的固化能耗测定值，并提出降低建材固化能耗的策略方法。

Embodied Energy in Buildings

Embodied energy is the energy consumed by all of the processes associated with the production of a building,from the acquisition of natural resources to product delivery.Embodied energy is a significant component of the lifecycle impact of a building.It was thought until recently that the embodied energy content of a building was small compared to the energy used in operating the building over its life.Most effort was therefore put into reducing operating energy by improving the energy efficiency of the building envelope.Research has shown that embodied energy can be the equivalent of many years operational energy.This paper discussed what is embodied energy and the assessment method of it.Finally,The article also provide some guidelines for reducing embodied energy.
