Documentation to support the performance year energy consumption figures reported above:
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls employed by the institution:
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs are in use at KCPA, Talbot Lab, ARC, ESB, McKinley and other buildings
A variety of types of LEDs are in place including downlighting, exterior canopy lighting and wall packs.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution:
Campus burns natural gas and coal to create steam for most energy needs on campus. These boilers have electric turbines attached to them so that the steam co-generates electricity that can offset the purchase of additional electricity for campus.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The retrocommissioning process on the Urbana campus is focused on reviewing and improving building mechanical systems, while maintaining or improving occupant comfort.
Overview
Engineers undertake a thorough investigation of available building documentation, energy usage history, and similar pertinent data, while conducting meetings with building staff.
Field technicians and tradesmen gather data regarding operating conditions, sensor accuracy, equipment condition, and historic maintenance data from the field and current maintenance staff.
The composite teams discuss findings and then look to restore mechanical systems to their original design while implementing energy saving improvements.
The teams take the lead in making small changes and recommending larger capital projects, which require more funding, to Engineering or Maintenance for augmenting and sustaining the building's energy saving strategies.
Building system control experts implement modern methods of control, monitor energy usage after changes, review actual metered data, and verify the savings.
