A brief description of when and why the building energy consumption baseline was adopted:

That year is when the Energy manager for the university was hired and began capturing accurate energy information for the campus.


A brief description of any building temperature standards employed by the institution:
---

A brief description of any light emitting diode (LED) lighting 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.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy sensors are installed in new construction projects.


A brief description of any passive solar heating employed by the institution:
---

A brief description of any ground-source heat pumps employed by the institution:
---

A brief description of any cogeneration technologies employed by the institution:
---

A brief description of any building recommissioning or retrofit program employed by the institution:
---

A brief description of any energy metering and management systems employed by the institution:

The university is actively purchasing new sub-meters for building without them. The energy manager captures and evaluates energy use on campus.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
---

A brief description of any energy-efficient landscape design initiatives employed by the institution:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
---

A brief description of other energy conservation and efficiency initiatives employed by the institution:
---

The campus has seen energy savings (when accounting for square foot increases) over the last three years through active programs in Facilities Management. Although the quantitative data is included in this report, much of the qualitative data was not captured due to shifting leadership and priorities in that department during the STARS reporting process.

The information presented here is self-reported.
