Our session will begin with the first presenter going over different financing options available for energy efficiency projects in existing buildings such as standard energy performance contracts, energy service agreements, and property assessment clean energy (PACE) before segwaying into a practical overview on main financial methods of calculating impacts and savings. The session will continue with our second instructor who will focus on understanding commonly used building performance programs such as Energy Star, Ashrae, LEED O&M and GRESB and the way they interact. This portion of the course will also cover more granular details on energy inputs in the benchmarking models, the differentiation between various energy audit levels, and a best practice roadmap to completing successful benchmarking. The third presenter will discuss how to understand environmental, social and governance factors and certifications which can be helpful to building owners and managers. There will be a special focus on GRESB fundamental structure and its important for management, and real estate market regulation.
The final instructor will walk the audience through The Tower Companies sustainability story in an effort to break down some of the basic green building steps required to set a good foundation for any sustainability program, with a focus on energy efficiency for existing commercial office and multi-family properties. The instructor will discuss setting goals and “how-to” implement benchmarking, LEED best practices, and energy management to yield successful projects.
