- Energy savings incentives. We worked with JPMC to implement energy saving measures in four of their locations in order to comply with Local Law 87. In order to offset the implementation cost, we secured funding for this project through NYSERDA’s Flextech program.
- At 3 Chase Metrotech Center (425,000 sq. ft.) we noted that garage exhaust fans were running at full capacity 16 hours a day, five days a week. By adding carbon monoxide sensors to the parking garage and installing Variable Frequency Drives (VFDs) to the existing exhaust fans, we enabled the units to operate based on demand rather than constantly at full capacity. The annual savings was $49,000, with a simple payback period of two years.
- At 4 Chase Metrotech Center (1,600,000 sq. ft.), we saw that the lighting schedule for a typical office was 6:00am to 10:00pm but observed that and floors were generally occupied from hours 7:00am to 8:00pm. This meant four hours of unnecessary lighting a day. We re-programmed the lighting schedules and trained the building staff on how to operate the override switches. The annual savings was $55,000, with a simple payback period of 2.2 years and a yearly energy reduction of 25%.
- At 383 Madison Avenue (1,400,000 sq. ft.), we installed differential pressure controls with a variable frequency drive for each zone heating distribution system in the building. By implementing this ECM, the pumps were modulated according to the load demand on the system. The annual savings was $22,000, with a simple payback period of five years and a yearly energy reduction of 157,424 kW.
