The ECM project team and FOD will be executing the outage. Physics facility team members will be on site to monitor the work.
A two day outage to allow the conversion of the existing main drives on the motors of Air Handler 1, Air Handler 2, and their related main exhaust fans from fixed speed systems to variable speed systems and to allow the installation of new flow sensors in the main exhaust plenum on the roof.
Normal preventive maintenance on other systems that was deferred from the last quarterly
outage will also be done during this outage and will include inlet filter changes
in both AHU-
Variable speed drives are a significant technology upgrade to the present systems and are a key component in achieving the targeted energy savings that the project seeks. An outage, with a corresponding building closure, is required because both air handlers and all exhaust fans need to be shut down at the same time. During this time, there will be crews working inside the ductwork of the main exhaust air plenum on the roof. The off condition is necessary for the safety of these workers. Preventive Maintenance work that was deferred to this outage was moved to minimize disruptions to the occupants.
The outage will take place the weekend of August 8-
Detailed plans for each day are as follows:
August 8: Beginning at ~7:00 pm, thermostats in labs will be lowered to approximately 65 degrees F to bring the room temperature down in preparation for the off condition that follows on the 9th. This added cooling will help the room to not overheat when air flow is absent and the presence of heat loads from equipment may remain.
August 9: Beginning at ~5:00 am, work will commence and both AHU-
August 10: Beginning at ~7:00 am, work will commence again and will include any residual work that was not completed on Saturday. Follow the links in the paragraph above for details of the Sunday work plan.
August 5-
The work will take place in the basement mechanical rooms near the air handlers and on the roof near the main exhaust fans and plenum. No work will be done during this outage in any labs.
Contractor teams from Bruner Corporation and SME and FOD maintenance staff will execute
the work. Crews will be working in parallel to limit the outage duration. It is
expected that a total of 20-
