After the U.S. Department of Energy halted its Energy Star program for medical office buildings in 2013, real estate investment trust Welltower developed its own proprietary system to evaluate total building performance.
The company’s Green Arrow Building Certification (GABC) program measures energy, water, waste, indoor air quality, and innovation. Over 230 properties in the U.S., Canada, and the U.K. participate in the program each year, with115 properties achieving certification.
The GABC program has helped identify areas of improvement and items in need of corrections. Most properties have seen a 1%-12% reduction in energy use as a result of the program. Energy, water, and waste usage are tracked monthly, and reports are sent to all real estate managers and engineers for review. Any buildings with an increased usage of 5% or more must be reviewed for probable causes to explain variances.
Welltower contracted with a third-party energy consultant to develop the program. Green Arrow was based on the foundation of both Energy Star certification and the Global Real Estate Sustainability Benchmark (GRESB).
