Thermostat Upgrade Project

This summer, the Civic Square Building will enter Phase II of a project involving the replacement of thermostats in most of the building. (Phase I was mostly Bloustein Classrooms, Forum and Lobby Area)

Digital thermostats (by Automated Logic, or “ALC”) will be coupled with occupancy sensors to control temperatures in offices and studio space.

Project Start Date: 6/18/2020
Project Completion: Late Summer

Scope

Bloustein: All offices on the first floor, the 3rd floor suite offices, half of the 5th floor (closer to the elevator) and the student lounge on the 2nd floor.

(Note: Bloustein 4th Floor is scheduled for Phase III and will not be affected this summer, allowing for our other projects there to continue, unhindered)

Mason Gross: All offices on the first floor, major studio spaces on the 2nd floor, the 3rd floor computer lab, The Center for Digital Filmmaking, the undergraduate studio space, and 4th floor major studio spaces.

Work Involved

Working around a sequential schedule, electricians and HVAC technicians will need to enter the ceiling space above the affected rooms and corridors. They will remove existing pneumatic actuators that control cold airflow and hot waterflow, and replace them with new electrically controlled actuators.

Rooms with an extant thermostats will receive an additional ALC thermostat. The old grey Honeywell thermostats will be deactivated, but not removed.

Occupancy sensors will be installed in all affected spaces, and will communicate with the thermostat that controls the temperature to that area. Occupancy will trigger that thermostat to achieve the user-defined setpoint. Unoccupancy will raise/lower the setpoint, depending on the season.

These changes will reduce the strain on our HVAC system and reduce our utility costs.

Challenges

Work will be done during typical business hours in the summer time and will have to be conducted around our staff. Workers will need access to every office slated for the upgrade at some point. The front desk will delegate key access to these areas.

Air quality / particulate is not of concern and REHS will monitor the situation and overview site plans.

Setpoints will need to be configured once the new thermostats are installed and this will likely require some trial and error. During the summertime, this will likely result in offices being too cold.

Additionally, actuator replacement will require hot water zones to be isolated. This may result in 3-5 surrounding spaces controlled by the VAV-box to lose their reheats, resulting in chilly offices. Issues like this should not last more than a day for most zones.

Current Schedule

The project manager intends on making a schedule, so we can predict who will be affected during certain times.

Occupants in the affected spaces will be notified beforehand on the dates work is intended to occur in their areas.
