The purpose of this study was to assess the feasibility of implementing Arc and BREEAM In-Use as turnkey tools to help Colorado State University (CSU) benchmark, analyze, and achieve its operational and sustainability goals. Arc and BREEAM In-Use are existing building benchmarking systems that assess building performance, supporting building and portfolio managers in strategically operating, maintaining, and continuously improving performance. In this study, the Institute for the Built Environment (IBE) at CSU assessed and compared the feasibility and utility of Arc and BREEAM In-Use for benchmarking and tracking building sustainability performance at CSU. From May through December 2018, IBE used both Arc and BREEAM In-Use to benchmark the performance of CSU’s Willard O. Eddy Hall. This report summarizes the comparative efficacy of Arc and BREEAM In-Use in supporting institutional sustainability goals, long-term cost savings, and management decision prioritization.
