So SFO required that their Design-Build teams, some of the best in the world like Austin Webcor Joint Venture + HKS/WB/ED2/KYA, evaluate each design element through a “comprehensive business case analysis” inclusive of “costs and benefits for all three bottom lines – financial, social, and environmental.” “To begin with, together with the Autocase team, we assessed 6 possible design features for Boarding Area B,” said Raphael Sperry of Arup, one of the key consultants on the project. “The green roof had a particularly compelling Triple Bottom Line Cost Benefit Analysis (TBL- CBA) – of $5 million over a 50-year timespan, supporting its inclusion in the project. In contrast, the ROI for the ground source heat pump was negative financially (TBL-CBA of –$5.23 million), and the analysis showed that level of investment was not outweighed by its environmental and social benefits. While ground source is an attractive technology, it’s not appropriate for every project, and this allowed us to put our resources where they will have a bigger overall impact.”

“Without Autocase, we would be shooting in the dark as to which design features are worth the money ” explained Anthony Bernheim, FAIA, LEED Fellow, Sustainability Manager for The Allen Group, LLC, providing program management consulting for the SFO Terminal 1 Redevelopment Program. “Traditional cost estimates are too narrow, emphasizing first costs over lifecycle costs, and forgetting about traditionally unquantified dynamics like the impact of indoor air quality on employee productivity, the benefit of interior landscaping for passengers and retailers, or the societal benefit of avoided greenhouse gases from renewable energy on our site. But those impacts are very real and they become quantifiable with rigor and with ease in Autocase.”

About Autocase: Autocase, software developed by Impact Infrastructure, automates the business case for smarter, more sustainable buildings using Triple Bottom Line Cost Benefit Analysis (TBL- CBA)https://en.wikipedia.org/wiki/Triple_Bottom_Line_(TBL)_Cost_Benefit_Analysis_(CBA). TBL-CBA is an evidence-based economic method that combines Life Cycle Cost Analysis (LCCA) and Cost Benefit Analysis (CBA) techniques to quantify and attribute monetary values to the Triple Bottom Line (TBL) – financial, social, and environmental – impacts of a given project or proposal. This more comprehensive version of CBA makes it possible to justify a project uncontestably to key stakeholders whether they be investors, government officials, or the local community.
