PROGRESS REPORT

Energy units are converted to one thousand British Thermal Units (kBtus) to allow for comparisons of electricity and natural gas usage. Goals and energy use are then stated in kBtu/square foot (sq. ft.). Estimated savings are based on energy consumption for the same time period from the previous year normalized to current energy costs and campus square footage. It does not take into consideration the climate difference between periods.

In fiscal 2022 the entire campus used 76.1577 kBtu/sq ft. That was a decrease of 1.2 percent from the previous year. However, even with the overall decrease in combined electricity and natural gas usage there was no estimated savings due to the increase of electricity usage.

In Table I, the campus energy use is broken down by utility type. The percent change column is the energy usage change from fiscal year 2021 to 2022.

Electricity	60.6060	60.5973	52.3605	54.9598	Up 4.9%	($97,204.98)

Total	89.2769	82.2748	77.0844	76.1577	Down 1.2%	($30,854.11)

In Table II, the campus energy use is broken down to compare fiscal 2012 to fiscal 2022, which shows an 8.77 percent decrease in overall kBtu usage per square foot. The savings is calculated from the usage change in the utility and the current price paid for that utility. The yearly cost savings compared fiscal 2012 to fiscal 2022 and was $191,960 which mainly comes from the drop in price of electricity.

In fiscal 2022, Angelo State University completed a project to replace all the arena lights if the indoor sporting facility. Fifty-six metal halide lights that are 1500 watts each were replaced with LED fixtures that will reduce the energy by 50 percent to 85 percent. The project was complete in January 2022. In addition, smaller projects of replacing fluorescent bulbs with LED bulbs are continually ongoing to both drop the energy use and extend life of bulbs to lower maintenance cost. The main change out is all of the parking lot lights being switched from 400-watt metal halide to 115-watt LED, a 70 percent reduction in energy use.

GOALS

In compliance with House Bill 3693, Angelo State University set a goal to reduce total electrical consumption by 2 percent for fiscal 2022. Table III below shows the kilowatt hours per square foot for the entire campus quarterly. This is all electrical usage whether it is in a building or on the grounds. It shows a 5.57 percent increase for fiscal 2022 as compared to the previous year, but a 7.2 percent decrease from five years earlier in fiscal 2017 (16.11 kwh/sq. ft. compared to 17.36 kwh/sq. ft.).

STRATEGY FOR ACHIEVING GOALS

1. Continue to monitor the upgrades/replacements to air handlers, electrical equipment and items at the central plant as according to the performance contract Angelo State University has with Tour Andover Controls (TAC). This is a $13 million energy savings project for the university that is to be paid over the next 15 years (2021) with the money saved from the improvements. The installations were completed in February 2009.
2. Maintain consistent temperatures across campus and don’t deviate to please individuals. The university has changed the original set points in order to save even more energy. For cooling, a set point of 74 degrees (73 degrees was the original). For heating, a set point of 68 degrees (70 degrees was the original). The university adopted this change in January 2011.
3. The elimination of personal space heaters.
4. Informing and training personnel to turn off computers, monitors, printers and similar items when not in use and overnight.
5. Monitor the utility meters for discrepancies and unexpected usage amounts. Verify anomalies and correct problems.
6. Inform university policymakers about the worst energy performing buildings and try to eliminate or make those buildings more efficient.
7. The Student Government Association has maintained a student-led energy conservation effort in the dormitories since 2015. The program focuses upon teaching students to turn out lights, set the AC at reasonable temperatures and take other simple energy saving steps. Essentially, it teaches them about how to be good stewards of their resources.
8. Continually replace light fixtures with LED lighting to reduce electricity usage.

IMPLEMENTATION SCHEDULE

The implementation schedule for cost reduction is dependent on the availability of technicians to install cost reduction measures. As time permits and funding is available to purchase items that could result in cost savings measures the university will take advantage and do so. The tracking of the measures implemented will be done by monitoring the utility usage for the area that the implementation took place.

AGENCY FINANCE STRATEGY

Angelo State University continues to take advantage of rebates and electrical provider incentive programs to lower the cost of LED lighting technology that makes upgrading to LED lights more cost efficient than replacing broken bulbs/fixtures with old technology. ASU also replaces high utility use equipment with the most efficient/best value for the state.

EMPLOYEE AWARENESS PLAN

Angelo State University publishes its energy report each year on the State Energy Savings Program page of the university website.
