Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	28,152.34 Metric tons of CO2 equivalent	26,324 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):

	Performance year	Baseline year
Start date	July 1, 2018	July 1, 2007
End date	June 30, 2019	June 30, 2008

A brief description of when and why the GHG emissions baseline was adopted:

The last time we performed a thorough GHG inventory was for the 4 year period of 2004-2008. This is the time period in which the university signed the Second Nature Presidential Climate Commitment the first time around, therefore the university was invested in greenhouse gas emissions reporting. The performance year of 2018 - 2019 is the fiscal year with the more accurate ongoing performance data as FY2020, July 2018 - June 2020, would not provide an accurate level of detail for operations and building performance as the majority of buildings were shut down March 2020 - June 2020 due to covid.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	3,147	1,409
Number of employees resident on-site	7	5
Number of other individuals resident on-site	7	4
Total full-time equivalent student enrollment	17,618	13,420
Full-time equivalent of employees	2,719	2,298
Full-time equivalent of students enrolled exclusively in distance education	3,575	350
Weighted Campus Users	13,367	11,883.50

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

	Performance year	Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user	2.11 Metric tons of CO2 equivalent	2.22 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

4.92

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

512,861.35 Gross square meters

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	11,896.51 Square meters
Healthcare space	634.34 Square meters
Other energy intensive space	12,292.92 Square meters

EUI-adjusted floor area, performance year:

550,215.97 Gross square meters

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:

0.05 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:

1. In 2016, Solar Panels are installed on Micron Business and Economics Building.The panels will be able to produce 25 kilowatts of power.
2.In the future, additional solar panels could be added, bringing the total power produced to 65 kilowatts, the equivalent of roughly 12 households.
3. The MBEB building is focused on natural light. The skylights and interior windows bring natural daylight farther into the interior of the building reducing electricity usage.
4.Geothermal heating (a renewable resource) delivered through radiant beams which require very low air flows
5. Highly automated building controls for HVAC systems and building lighting
6. Live green roof that reduces heat gain, air conditioning costs, and storm water run-off
7. 720 tons of demolition material was recycled during construction.
8. Energy Efficient Fluorescent Lighting through the use of modern fluorescent ballast technology and design simulation, the placement and quantity of light fixtures achieve a savings of 32% vs. the code lighting requirements—enough to power three single-family homes.
9. Active Chilled Beams: An active chilled beam induces room air through a heating/cooling coil to temper the space. This technology transfers less efficient air delivery to more efficient water delivery systems, resulting in a 75-80% fan energy savings and lowers the overall energy consumption of the building.
10.Energy Recovery Ventilation:The ventilation air is tempered through the use of energy recovery wheels. The exhaust air from the building passes through the energy recovery wheel transferring up to 75% of its energy. The energy recovery system reduces the size of the central heating and cooling systems and reduces the overall energy use of the building.
11.Variable Speed Pumps/Fans: The variable frequency drives (VFDs) adjust the speed of the pumps and fans to match the building load . Since a typical building operates at partial heating and cooling loads over 95% of the year, VFDs provide significant energy savings.
12.Low Emissivity Glazing:Use of low-e technology reduces energy consumption by cutting the amount of heat lost through the glass during the winter months. In summer, it blocks up to 90% of the long-wave (heat) radiation from entering the building.
