Energy and environmental standards, like ISO 50001 and ISO 14001, have a significant influence on the sustainable performance of companies worldwide, while international sustainable building rating systems are often the chosen method to quantify and benchmark performance. This research aims to comprehensively evaluate and assess the performance of these standards in relation to both the LEED and BREEAM assessments. Based on a clearly defined methodology, each standard topic and assessment criteria are comprehensively evaluated and discussed in detail. The main outcome of this research is that through a combination of these standards, a minimum of a LEED Gold or a very good, four-star BREEAM certification is achievable. Furthermore, the highest potential areas for improvement in companies with mature standards are highlighted as well as recommendations for companies with less mature standards and projects in the design and planning phase.
