A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UH is presently drafting an Energy Master Plan to determine these practices for coming years.
A brief description of energy use standards and controls employed by the institution:
As of 2016 all new buildings will be LEED certified Silver as a matter of design standards.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University of Houston has an active LED transition program. Projects are evaluated on their potential for savings within two years of installing new LEDs. All outdoor lighting has transitioned to LED, the underground tunnel system, and major lecture halls. Further more all new buildings will be LEED certified silver and must comply with related mercury lamp reduction credits.

Data source(s) and notes about the submission:
The significant difference in "Imported steam, hot water, and/or chilled water" reported between Baseline Year and Performance Year is due to the deactivation of the University of Houston Medical Center building. This building, being separate from UH's Central Plant, required the importing of steam, hot water, and chilled water while it was operational. Since Hurricane Harvey in 2019 the building sustained significant flood damage necessitating its closure and drop in needed steam, etc. The remaining reported MMBtu are still for this building but in a deactivated capacity.
Additionally, Stationary fuels used on-site to generate electricity and/or thermal energy is drastically lowered from previous years due to these coming from generators that are used as part of a peak demand response program (I.E. the generators are turned on to reduce grid strain.). The mmbtu here are results from the generators being run monthly for maintenance and upkeep as opposed to full service.
