LCA OF TWO STORY OFFICE IN IRAN WITH THREE DIFFERENT WALL TYPES

Abstract

Annual energy consumption and annual global wai, ling potential (GWP) decrease with improving the energy performance of the building, whereas the embodied energy and embodied GWP increase due to the extra material and products applied. The issue of Life Cycle is quite new in the countries like Iran, so does it effective or does it work in developing countries. The main goal of this study is to use three different wall types in a two story office with close embodied energy and U value (overall heat transfer co-efficient) and compare the performance of each wall in the building from the Life Cycle point of view. Subsequently, analysing the importance of other factors such as embodied carbon and transportation in choosing appropriate material in construction sector. According to this study, even in countries like Iran (which holds the world's fourth-largest proved crude oil reserves and the world's second-largest natural gas reserves) with very low amount of database about the embodied energy, choosing the right material should be done to reduce the fuel consumption and CO2 emission.
