Meeting/Event Information

Even though the U.S. Building Codesare becoming more energy stringent, our country’s Energy Utilization Index(EUI) is rapidly increasing every year because only 5% of our commercial building stock is being built or renovated each year. This means that the remaining 95% of our commercial buildings are experiencing reduced energy performance each year. This trend in existing buildings can be changed by the implementation of a Technical (testing based) Retro-commissioning (RCx) program that incorporates technical energy audit procedures, measurements of building performance metrics, savings calculational procedures and corresponding financial analysis methodologies that building owners can understand and interpret for developing both short term and long term programs for building systems’ upgrades. Case studies are presented for various RCx projects that demonstrate the advantage of conducting a Technical RCx program and the merit of implementing an Ongoing Commissioning (OCx) program for a building owner to be able to maintain a sought level of building performance for an ongoing basis.
