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

The baseline was adopted based on the data and technology availability, which allowed for direct comparison between the baseline and performance year with no alterations to sensors or data availability.

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

We have building automation systems for most of our HVAC systems. These allow for setbacks through our Building Automation Services department to reduce flows and/or change temperature set-points during unoccupied times.

A brief description of any light emitting diode (LED) lighting employed by the institution:

We use LED light bulbs in various hard to reach spaces and in elevator light fixtures. These are all ‘can’ light type fixtures and are used in less than 1% of our building space.

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

We use dual technology (infrared and ultra-sonic) occupancy sensors in roughly 50% of the restrooms on campus. These sensors are mounted to the ceiling and sense when a space is occupied. When a space is continually unoccupied for 15 minutes the lights to the space will be automatically turned off, but they also automatically come back on when motion is detected.

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:

Installation of occupancy sensors in campus building restrooms
Qualified Energy Savings Project (QESP)
Recommissioning of building mechanical systems
Installation and upgrading of campus building utility meters with the ION system
Use of Building Automation Controls
Ongoing replacement of building system components through CFS projects such as pumps, air handlers, constant air volume boxes which are more energy efficient
Installation of variable frequency drives on motor and pumps

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

All appliances must be EnergyStar as required by IU Purchasing Policy.

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

- IUPUI has received Tree Campus USA designation every year since 2012
- IUPUI has a canopy coverage goal for the campus and is actively working to achieve that goal, with a priority on native plant usage

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

We use a vending miser apparatus that uses infrared motion sensing to turn off vending machines that have not been used for 15 minutes. These are only on a handful of machines on campus, and make up less than 1% of the vending machines on campus.
