Analysis of High Performance Sustainable Building Practices at PNNL Shows High Return
A recent PNNL study examined the cost-effectiveness of implementing measures that meet the criteria for DOE's high performance sustainable buildings (HPSBs) standard in 3 different types of buildings on the PNNL campus: offices, scientific laboratories, and data centers. In each of the three case studies examined, the investments made to achieve HPSB status demonstrated a high return.
Simple paybacks for total investments in the three case study buildings ranged from just 2 to 5 years; savings-to-investment ratios all exceeded the desirable threshold of 1; and the net present values associated with these investments were all positive. The full analysis can be found in the report titled, "The Cost-Effectiveness of Investments to Meet the Guiding Principles for High-Performance Sustainable Buildings on the PNNL Campus."
