Thermostat Upgrade Project

The Civic Square Building entered Phase II of a project which involved 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”) were coupled with occupancy sensors to control temperatures in offices and studio space.

Project Start Date: 6/18/2020
Project Completed: 10/2020

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 entered the ceiling space above the affected rooms and corridors. They removed existing pneumatic actuators that controlled cold airflow and hot waterflow, and replaced them with new electrically controlled actuators.

Rooms with an extant thermostats received an ALC thermostat. The old grey Honeywell thermostats were removed.

Occupancy sensors were 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 was done during typical business hours in the summer time. Workers needed access to every office slated for the upgrade at some point.

Air quality / particulate was not of concern and REHS monitored the situation and overviewed site plans.

Setpoints will need to be configured over the course of a year 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.

Current Schedule

This work was performed during the summer and fall of 2020 with minimal disruption to office occupants. There was minimal staff presence in the facility during this time due to the COVID-19 pandemic.
