There are eight pre-qualified energy service companies (ESCO) approved to execute energy performance contracts (EPC) at any of the five University of Illinois campuses. Depending on the scale of the EPC project, RFPs (request for proposal) are usually sent to at least four ESCOs on a rotating basis. The four competing ESCOs conduct high-level preliminary technical audits (PTA) of the facility and each ESCO provides a list of potential energy conservation measures (ECM) detailing cost, energy savings, and payback. An ESCO is selected after review of the audits and formal interviews.
Air Handling Unit (AHU) -
a device used to regulate and circulate air as a part of a heating, ventilating, and air-conditioning system.
Clean Room -
a controlled research area designated by a low level of environmental contaminants, typically through specialized mechanical systems.
Direct Digital Control (DDC) System –
automated control of a condition or utility-related service by a digital device.
Exhaust Fan –
fan designed to circulate air from inside of a facility to the outside.
Fume Hood –
a ventilation system which exhausts fumes, vapors, and dust from a partially enclosed workspace.
Heat Recovery System –
the process by which incoming air to a facility is preheated by outgoing exhausted air.
recyclable insulating materials added to pipes and equipment to prevent heat loss.
Occupancy Sensors –
control device that detects occupancy and turns lights and HVAC equipment on or off automatically.
Process Water –
non-potable water used in connection with utilities systems and operations.
work associated with technological and materials upgrades to existing equipment.
Steam Traps –
self-contained valve which automatically discharges condensate and non-condensable gases and limits the loss of steam used to heat the campus.
Variable Air Volume –
an air distribution system capable of automatically delivering a reduced volume of constant temperature cool air to satisfy the reduced cooling load of individual zones.
