Methodology to assess the cost-effectiveness of sustainable measures in buildings

Abstract

Many recognize the value of sustainable construction as it reduces the negative impact on the environment and improves quality, accessibility and productivity for all of those who live and work inside buildings. However, economical advantages, which would help expand the concept in the marketplace, have not yet been established. The objective of this paper is to present a methodology to assess the cost-effectiveness of the application of sustainable measures in buildings through actions that establish a balance between environmental, economical and social factors. The methodology is based on the comparison of a case study (a building in which sustainable concepts were applied) with reference buildings making it possible to demonstrate triple bottom line added values. The aim is to achieve an optimum balance point, with an acceptable pay-back time and to provide evidence of good economic results in order to encourage the investment on sustainable construction.
