35、 SocietyIntroduction 19IntroductionThe U.S. Green Building Councils (USGBC) Paid-from-Savings Guide to Green Existing Buildings provides owners, architects, engineers, facilities managers, and energy service companies (ESCOs) with detailed information on how to use the paid-from-savings approach to

36、green an existing building with the goal of achieving LEED for Existing Buildings: Operations & Maintenance certification. *bundled : In paid-from-savings projects, building system improvements generate utility cost savings. These savings are leveraged to help fund the project. Paid-from-savings pro

37、jects seeking LEED certification can “bundle” or aggregate the utility cost-saving measures with non cost-saving measures to optimize green opportunities and project economics. When longer pay-back measures are combined with the quicker measures, the project will have a shorter overall pay-back peri
