Johns Hopkins Hospital
Johns Hopkins University (JHU) recently began a campus-wide sustainability initiative, which included organizing its maintenance, renovation and development activities around new sustainability principles. The School of Medicine's Facilities Management Office sought LEED certification for several facilities. We were hired to conduct a Sustainable Return on Investment (SROI) evaluation for four laboratory buildings.
Following a risk analysis process session, we produced a comprehensive set of sustainable output metrics. The findings were generated by a 20-year spreadsheet-based economic simulation model that identified all costs and benefits associated with the sustainable initiatives, including efficient lighting, variable air volume systems, heat recovery wheels, recycling program, grey water system and low-flow fixtures. Research was conducted to determine the proper values of each input and to determine how they could be quantified and incorporated into the cost-benefit analysis model.
We estimated $3.57 million, or nearly 500 percent, annual SROI. The benefits included traditional cash benefits such as savings on utility bills, as well as non-cash benefits such as increased health and productivity, reduced chemical pollutants, reduced greenhouse gasses and reduced waste production.
