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

The defined baseline period was adopted as part of the campus Energy Transition Plan adopted by the MSU Board of Trustees on April 12, 2012. The baseline was selected to coincide with the final data considered in an engineering study done for MSU by Black & Veatch. (The study is an appendix to the Energy Transition Plan.)

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

Over 80 percent of campus is control through a central energy management system the employs various controls for setback of temperatures during unoccupied hours of operation.

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

MSU has installed LED lighting in a parking ramp and other exterior lighting. Renovated offices and the lunch room at the IPF Building have also used LED lighting.

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

All new construction includes occupancy sensors for lighting control, renovations include installing photocell controls in stairwells with sufficient glass to lower light during daytime hours, dual technology occupancy sensors have been employed in labs to control lighting and setback ventilation during unoccupied hours to reduce energy consumption.

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 2012 addition to the Life Science Building uses ground source wells to meet the heating and cooling needs of the nearly 48,000 square foot addition.

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

T. B. Simon Power Plant is a system of independent steam generating units operating on a common 900 psig (pounds per square in gauge) steam header, which can supply energy to 99 Megawatts of cogeneration electric capacity. Cogeneration of energy can range from 60 to 80% efficient, while a typical electric only generating facility operates at 30% efficiency. The T. B. Simon Power Plant is a co-generation facility which provides steam and electricity to the campus with 60% efficiency. The existing campus energy distribution system includes underground steam tunnels and electrical lines that provide heating and power to the buildings. The power plant has fuel flexibility and currently operates reliably with one of the six generating units out of service for maintenance. The T. B. Simon Power Plant has an interconnection to the local utility for reliability and back up in the event a single unit is unavailable to generate electricity. In case of an entire plant outage, the plant has “black start” capability that allows restarting the plant in a very short time period.

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

A program to commission 16 million square feet of building space was begun in 2009. This retro-commissioning project includes ASHRAE level 1 and level 2 audits as well as calibration of controls and balancing of air and water flows within the HVAC systems. See http://bespartangreen.msu.edu/treasure-hunt.php for more information.

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

Central energy management has been a standard at MSU since 1972. Central energy management is BACNET compliant to allow integration of various vendors equipment. Some of the vendors utilized on campus include Siemens Building Technologies, Delta Controls, Phoenix lab controls, Ingenuity air quality controls. Demand ventilation, economizers, heat reclaim, time of day scheduling, start/stop optimization, VAV plus, occupancy sensors in conjunction with air quality sensors are technologies employed to reduce energy consumption. Over 100 buildings are connected to the building automation system.

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:

In conjunction with the Better Buildings Challenge, a federal sustainability initiative through the U.S. Department of Energy, the university has committed to reducing energy use by at least 20 percent over its 20 million-square-feet contiguous campus by 2020. To achieve that goal, the existing-building commissioning process will be deployed across MSU’s aging building fleet. This process is used to “tune up” campus buildings so their systems operate as efficiently as possible. IPF’s Commissioning Services crew is devoted solely to this effort.
