A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Starting in 2021, we began an load-shedding program with Eversource during times of grid stress. This includes shedding load with cooling towers by either raising temperatures in buildings or turning off air conditioning/heating for a period of a few hours (minimum 3 hours). We plan to encourage the campus community to reduce load on their own by educating them about the campus efforts with Eversource.

Eastern's energy dashboard is available Eastern's website to view energy useage. The dashboard includes a variety of data and displays, including energy usage per building and logged data. https://www.easternct.edu/facilities/energy-dashboard.html
This application was created with a collaboration between the Facilities department and Automated Building Systems, Inc. The electrical data shown is captured and logged by the Alerton building management system, which also controls the temperature and air changes (HVAC) in most of the campus buildings. The Alerton and Encelium systems work together to adjust to energy needs across campus.

The use of the Encelium system throughout campus allows individuals to dim the lights in their areas, which significantly contributes to energy use reductions and savings. Encelium includes lighting and occupancy controls. The lighting controls allows the lights of whole buildings to be dimmed to 70% of their typical lighting, with further dimming or turning off enabled for occupants. The occupancy controls allows the lights to turn off and the HVAC to reduce the number of air changes if a room is unoccupied for a set period. An increased number of occupants would also cause the system to increase the number of air exchanges in the room. This system saves money and energy, as the energy used is tailored to the needs of a building's occupancy level.

Every semester, residence halls compete for the Dean's Cup, which includes a month-long competition to reduce electricity use, earning the hall that reduced their usage the most points toward the Dean's Cup.

Signage is posted within buildings regarding their LEED status.

A brief description of energy use standards and controls employed by the institution:

Heating cooling range is set at between 69-and 73 degrees Fahrenheit according to Connecticut state statutes. The state has guidelines for the start dates of heating and cooling seasons which Eastern abides by.

In Eastern's Library, Gelsi-Young Hall Administration Building, Fine Arts Instructional Center, and the Student Center there has been installation of an Encelium Energy Control System that utilizes six different energy management strategies in order to maximize energy savings.

The Encelium system utilizes the following strategies to maximize energy savings:
-smart-time scheduling for zones not appropriate for occupancy sensors,
-daylight harvesting to the adjustment of lighting levels based on natural sunlight,
-task tuning to avoid over lighting particular areas,
-occupancy controls to automatically turn lights off when not needed,
-personal controls so individuals can set their own workspace preferences, and
-light dimming to shave peak demand and reduce energy consumption.
We can track performance by building, year to year to manage consumption and loads.

All campus buildings are connected to a building automation system that allows Facilities to set heating and cooling ranges or set points that prevents individual buildings from using energy beyond the set points (5-degree range), providing set temperature ranges available to occupants.

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

LED lighting is utilized in exterior site lighting throughout most of the campus. Interior LED lighting is also utilized at Hurley Hall dining area and bathrooms, Webb Hall faculty office wing hallway lighting, Student Center, Goddard Hall, Communications Building, Shafer Hall, Facilities Building, two parking garages, Fine Arts Instructional Center, Noble Hall, and Athletic Complex parking lot.

Most of the exterior lights are set with solar sensors to control when the lights turn on and off and reduce unnecessary energy usage.

We also utilize daylighting controls in the Science Building, Communications Building, Goddard Hall, and our parking garages to further reduce energy usage.

In summer 2022, five residence halls will be updated with LED lighting in hallways and common areas.

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

Our nine-story residence hall, High Rise, has geothermal heating and cooling.

A brief description of co-generation employed by the institution:

The Science Building has a 400kw fuel cell which converts natural gas into electricity and both high and low-grade heat for the building. In 2017 we replaced the 400kw fuel cell with a 440kw fuel cell.
In summer 2021, a Bloom Energy fuel cell was installed by the Admissions Building, for 1.2 kW of energy.

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

Eastern purchases Energy Star appliances for the residence halls, which includes stoves and refrigerators. Energy Star AC units are used on limited buildings without central AC.

Eastern has been retro-commissioning buildings through utility incentive programs. The Fine Arts Instructional Center retro-commissioning is completed. We are embarking on retro-commissions for Webb Hall, Gelsi Young, and the Student Center, which should be completed by late fall 2022.

We are also designing high-efficiency boilers to provide heat to the Library and taking the building off of the main boiler plant.

Additional documentation to support the submission:

Eastern does no import steam, hot water, and/or chilled water, so 0.0 MMBtu was reported.

For "Electricity from on-site, non-combustion facilities/devices, performance year (kWh)," only data for the Science Building fuel cell was included because the Admissions Building fuel cell was not yet online during Fiscal Year 2021 (July 1, 2020 - June 30, 2021). This data was provided by Edward Figiela, Plant Facilities Engineer 2 in Facilities Management and Planning.

For the next submission, use the Fiscal Year 2021 data above as the baseline year for this credit to account for updated data and methods (updated since 2020 with fuel cell data).
