A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

In 2017, FSU entered into a multiyear contract with Cenergistic LLC, to build a customized energy conservation program. The program goals include conserving energy, saving dollars the university can reinvest, preserving a quality learning environment for students, and increasing awareness to empower energy users to be energy savers.
As of 2017, FSU has hired a dedicated staff member to implement a ‘Green Labs’ Laboratory Air Change Reduction program in research laboratories targeted at reducing energy waste due to HVAC service. FSU’s research buildings consume about 38% of energy on campus, with an estimated 70% being attributable to special exhaust and HVAC systems. Additionally, laboratory spaces are, on average, unoccupied for 75% of each day. FSU’s Laboratory Air Change Reduction Program aims to reduce this wasted HVAC energy and has been implemented in 2 out of about 35 research buildings. The program will continue to expand, with an estimated completion date in 2020.
Through the Green Office program, staff at FSU learn about energy usage in their offices and strategies to mitigate usage such as: turning off lights, shutting down computers, printing less, getting rid of personal printers, etc. The Green Office program is voluntary, and several individuals from each office take the leadership role with support from the Sustainable Campus Green Office Coordinator, educating colleagues about new office strategies to reduce energy waste.
Throughout the Eco-Reps program, students learn about energy consumption and ways to decrease energy usage in their personal lives and on campus. Eco-Rep students create activities and educational programs in their residence halls to educate their peers on energy saving options.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Vacancy sensors are used extensively throughout the campus, both in lighting and HVAC systems in many buildings. FSU has a sophisticated scheduling process that incorporates student class schedules and events into a database. Buildings systems are then scheduled based on occupancy. Buildings employ either an ON/OFF or temperature set back process depending upon the type of building and the specific requirements of each occupant. After hours, where possible, HVAC systems are shut down or perform at a greatly reduced capacity. In addition, most room temperatures are controlled within a standard range based on the type of systems and specific environmental requirements.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

FSU’s exterior lighting standard for all new construction is LED. Some offices and classrooms are LED where financially feasible.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The natatorium at the Leach Recreation Center uses 166 solar thermal panels for pool heating. The system is capable of providing all pool heat during warmer months as well as a fraction of the heat during cooler months.
FSU’s Utilities provider, City of Tallahassee, completed a 20MW solar farm in 2017. FSU committed to purchasing 60% of the commercial allocation of the solar farm, which makes FSU the largest single consumer of solar energy from City of Tallahassee. The next phase 40MW solar farm is to be completed in 2019, at which point FSU will be 10% powered by solar energy.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

The University upgrades energy consuming appliances and systems with high efficiency alternatives when the savings demonstrate a payback of 7 years or less.
The University has reduced its energy consumption through a variety of retro-commissioning projects, event scheduling, equipment upgrades, and automated control system improvements.
FSU continually recommissions buildings to extract additional energy savings while maintaining the appropriate environmental conditions for the spaces.
