Energy Highlights FY 2022 vs FY 2021 - Post COVID-19 Impact

**Reported metrics are for the Dallas Main Campus – All Facilities Tied into Substation, Patterson Hall & Mustang Central Plants**

(89% of total SMU power, 90% of natural gas, 93% of water)

Square Footage no change at 4,542,437 (up 4% - 167,059 sq.ft. - from FY17 baseline)
No new construction was added in FY22.
Electrical Consumption was up 9% from 76.5 million to 83.7 million kWh (down 7% from FY17 including new construction)
When new construction is removed, consumption is down 12% from FY17 baseline

Electrical consumption was up significantly due to the post-COVID era return to full operation on campus. Key contributors to this increase was the return of the campus to normal operating hours and temperatures, buildings filled with warm bodies which increased demand for conditioned air. Additionally, there was a shorter winter break than the previous year and full summer activities on campus which eliminated the opportunity to set residential rooms to unoccupied.
Electrical Costs were up 19% from $4.0 million to $4.8 million (down 26% from FY17 baseline)
Electrical cost was direct result of an increase in consumption. There was also a slight overall increase in cost per kWh from $0.0535 to $0.0572 primarily due to Uri storm impact (big sellback in FY21, change in Ancillary costs) and a 5% increase in Heat Rate.

Natural Gas Consumption was up 5% from 275,481 to 289,615 MMBtu (up 13% from FY17 baseline)
Increase is due to full campus conditions and steam and condensate loop leakage issues. New metering on the condensate loop continues to show a very high volume of “make-up” water indicating water losses throughout the steam system. The high volume of make-up water causes the boiler plant to consume more gas.
Natural Gas Costs were up 8% from $1.1 million to $1.2 million (down 2% from FY17 baseline)
Natural gas costs were up due to increase in consumption.
Total Energy Costs were up 15% from $5.08 million to $5.96 million (down 22% from FY17 including new construction)
Energy rates are largely fixed in both electricity and natural gas, reflecting SMU strategy for predictability and stability. The past two years have proven this to be an excellent strategy. Electricity is hedged through 2030, while natural gas is hedged through 2024.

Energy Metrics Summary

Goal: Reduce 10% from FY17 Baseline

EUI –The Energy Utilization Index has returned to pre-COVID levels for reasons previously explained. However, as a later slide will show, our central plants continue to operate very efficiently, so the inefficiency is driven by other facilities. Natural gas use also continues to climb, negatively impacting this metric.
ECI –Though the Energy Cost Index has increased, it remains well below target. This includes cost of power and natural gas. FY21 was very low due to “sellbacks”.
KWH/GSF – Electrical energy consumption per gross square foot of campus building space was right on target.
KW/Ton – The Central Plant efficiency remains excellent, improving to 0.60 and remains at levels well below our goal of 0.66 for a rolling 12 month average.
Metrics presented represent all facilities powered by the SMU electrical sub-station. This includes all the West Campus with the exception of the Childcare facility and the Daniel House apartments.
Also, it does include the Robson Aquatic Center. All other East Campus facilities are excluded.

Gallons measures total domestic water consumed for the year. Domestic water is used in building facilities, central plants, and irrigation. Further breakout of this utility is shown in the pages that follow.
In FY22 there was an 11% reduction in domestic water consumption compared to FY21.
The WUI (Water Utilization Index metric) which declined 30% in FY22, does not include irrigation water, and measures gallons per square foot of building space. See following page for more detail.
Additionally, 1,253,000 gallons of gray water was reused on campus (e.g. Moody Coliseum & RC Commons toilets, Irrigation)
Also, it does include the Robson Aquatic Center. All other East Campus facilities are excluded.

Gallons in this table shows total domestic water usage for irrigation systems.
Irrigation volumes and metrics in FY22 remained nearly the same as in FY21
The main campus system has 1,333 irrigation zones, and over 11,000 rotors and sprayers, plus miles of drip irrigation.

WUI measures total domestic water consumed compared to total square feet of building space, and includes irrigation.
This metric is significantly influenced by weather and rainfall.

This metric shows the water consumed for irrigation compared to total square feet irrigated.
Irrigation volumes and metrics in FY22 remained nearly the same as in FY21

Managed return to post-COVID environment as the campus resumed normal operations and schedules.
Total SMU utility spend was up imperceptibly by $36,811 (electricity & natural gas & water combined).
Received $50,000 for SMU’s participation in the ERCOT ERS30 program and avoided an estimated $77,000 in taxes for power.
Continued to exceed and even improve our cooling plant efficiency metric (KW per ton) for four consecutive years, well ahead of the national average.
Reinstated the Evaporation Credit with UP Water for $41,000
Continued Energy Recommissioning activities in campus facilities and the Central Plants, improving their efficiency and comfort levels.
Organized & launched the first Energy Management Summit for Texas universities to encourage interchange among peers
On-boarded utility metering (Hill Top Heights Apartments, 6300 N. Central Expressway)
Significantly reduced chilled water losses
