Larsen & Longfellow Commissioning

On April 28, the Office for Sustainability commissioning team, along with Bob Phillos, Assistant Director of Operations from the Graduate School of Education, and Kevin the HVAC technician from Facilities Maintenance Operations, commissioned recently renovated spaces in Larsen and Longfellow Halls. They checked the lighting, lighting controls, programmable thermostats, and split system air conditioners that were associated with the renovation projects. Everything looked good with the AC condensing unit (as verified by the two Kevins and Andrea). We found three meeting rooms with ceiling mounted occupancy sensors that weren't connected correctly (these have since been fixed). We were told by the occupants of Longfellow that they'd like to be trained on how to use the thermostats (training is being arranged). We also noticed that the lighting levels varied drastically from one office to the next even with the lights on (from 15 FC on the desk of some unrenovated offices to between 30 and 50 FC in the renovated spaces). The commissioning was part of the LEED for Commercial Interiors program and included reviewing balancing reports for a new air handler, which was separatley commissioned by a third party.
