School of Arts & Sciences Williams Hall Renovation

---

Overview

STPCx personnel have served as the commissioning agents for the Williams Hall renovation on the first, second, third, and mechanical levels. The project entailed the demolition of existing variable air volume units and controls (reheat HW system and control valves) on the first and second floor, the installation of demand controlled ventilation on the first through third floors, and the installation of a new air handling with connections to existing ducts, electrical, piping, etc.

The commissioning involved activities and procedures focusing on the MEP infrastructure, Aircuity demand control ventilation, life safety items, and building automation controls.

Saving Energy Through Reading CO₂ in Classrooms

Unique to this project is a VAV system capable modulating the air flow to work in conjunction with classroom C02 and ventilation requirements. The installation of the Aircuity system provides improved ventilation during peak hours of occupancy. Buildings without demand controlled ventilation are usually over ventilating classrooms during periods of low occupancy which results in increased cost. The Aircuity system has the ability to process space CO2 levels and modulate the airflow depending on the number of rooms in alarm.

Commissioning verified the functionality of specific energy items related to the AHU, demand controlled ventilation, and verified other energy items such as a AHU nightly shut-down schedule and a seasonal HW temperature set-point schedule.
