The building had undergone the commissioning process as a component of that Certification, and currently practices ongoing commissioning. The local utility company offered a program for retro commissioning, and the building requested being a part of the program to meet this credit. Based on a review by their third-party commissioning partner - including an analysis of our ongoing commissioning practices - and due to our energy usage of 7.1 kw/sf/yr versus average consumption of 19.95 kwh/sf/yr for comparable buildings in this area, the local utility company felt a retro commissioning would likely yield no productive results, and therefore we were removed from the program for these extremely positive factors. We request that these factors and our documentation of continuous commissioning practices be acceptable as an alternative method to comply." "The project team seeks an alternative compliance path for credits related to commissioning given historic commissioning activities and current energy performance levels. Under normal circumstances, compliant energy auditing or commissioning activities must take place within 5 years of the end of the LEED performance period. The project building is eligible to earn EA Credit 2.1 without conducting commissioning or energy auditing activities within 5 years of the end of the performance period if the conditions outlined in A, B, and C below are satisfied: A) The project building can demonstrate that energy performance, when normalized for key variables such as occupancy, operating hours, and weather, has improved or remained steady since the initial commissioning activities. B) Initial commissioning activities occurred within 10 years of the end of the performance period. C) At least one of the following is true: 1. The project team\'s is currently implementing an ongoing commissioning program that meets the requirements for EA Credit 2.3 (e.g., rises above the level of standard preventive maintenance activities to proactive, continuous functional testing) 2. The project building currently has an Energy Star rating of 95 or greater Projects using this approach to demonstrate compliance with EA Credit 2.1 are also exempt from demonstrating implementation of no- or low-cost operational improvements and capital planning for EA Credit 2.2: Existing Building Commissioning: Implementation. However, normal measures for showing compliance are required for all other aspects EA Credit 2.2 (e.g., staff training, observed benefits of energy saving measures, and routine updating of the building operating plan).
