Know anybody who has had a heart valve replacement? With over 106,000 replacements a year, chances are you do and may not even know it. Edwards Life Sciences is known for their transcatheter heart valves. With a growing campus in sunny Southern California, they inherently knew their sky high electric bills were heavily impacted by the sun. So they were referred to the building scientists at 3FFICIENT (previously PE Consulting) to conduct a thorough roof analysis for options.
3fficient conducted a thorough analysis of solar and green (vegetated) roofing options in 2008. Based on existing conditions, a mix of solar and vegetated roofing was recommended, resulting in a 7% reduction in the campus electric usage and 14% ROI.
