Today, increasing rates of energy and resource consumption in the world have led the building sector to challenge the development of a new Building Life Cycle Assessment (BLCA) method. Moreover, some building designers and decision makers are concerned about a group of related aspects of BLCA (e.g. energy and carbon efficiency) in their designs. This approach can sometimes cause further negative issues in terms of unregarded values (e.g. related to quality of the acoustic environment). The aim of this paper is to determine the relationship between energy/carbon efficiency and quality of the acoustic environment based on a numerical semi-quantitative method, using various material scenarios in a typical building unit. The results present findings of an objective study which would help building designers and decision makers to consider the unregarded values as well as to involve different aspects of building design (e.g. energy and carbon efficiency, and acoustic comfort) in a more sensitive and more precise numerical manner.
