Impact of sustainable building and energy certification: financial and sustainability analysis of BREEAM certification

Abstract

Over the last few years, a great development in environmental sustainability has been observed as it has adapted to different cultures and fields all over the world and has been included as a main focus in the different valuation methodologies. Thus, one of the sectors that has recently been implemented is the construction sector in both residential and non-residential housing. The aim of this study is to analyse the BREEAM energy certification, its variables, valuation methodology and contrast them by means of a practical business case of construction and housing reforms, carrying out a sensitivity analysis. The results obtained demonstrate an improvement in the measurement of financial impacts, with cost improvements and improved housing performance together with a greater social impact and sustainability in both short and long term.
