Wylie Independent School District (ISD) is a fast-growing school district near Dallas, Texas. Serving over 17,000 students across 41 square miles including 20 campuses and 4 auxiliary buildings, the district’s facilities manager Marcia Coker used BuildingOS to centralize data from 25 buildings and over 100 meters.
In response to the COVID-19 pandemic, Wylie ISD shut down its schools for the remainder of the 2019-2020 school year. Since the decision was made close to the district’s planned spring break holiday, Coker had already rescheduled buildings to operate at the base load, which is the minimum amount of electricity needed. Using BuildingOS dashboards, Coker was able to easily verify the district did not exceed an average demand of 406kw during the closure. For perspective, average demand at Wylie ISD in 2019 was 762 kw. Initially, Coker leveraged BuildingOS by setting automatic alerts to ensure setbacks operated according to schedule. She also used BuildingOS to track and report on savings derived from these setbacks. With her Spring shutdown running smoothly in the background, Coker was now able to turn her attention to developing a long term plan to operate the district for an extended shutdown.
Measuring and verifying performance
Taking into account the affects occupancy and weather have on the performance of a building, Coker created a Project within BuildingOS. The Projects application uses the industry-standard International Performance Measurement & Verification Protocol (IPMVP) Option C to track energy and cost savings. The BuildingOS Projects app created a regression model that allowed Coker to compare energy performance to a baseline seed period established from historical portfolio trends.
This meant that when Coker analyzed Wylie ISD’s significant energy savings, her Project baselines aggregated data that was normalized for fluctuations in temperature to present an accurate reading of the energy savings that took weather and occupancy into consideration.
Measuring total electricity savings
Taking into consideration heating and cooling days, the district has saved over $53,000 at the time this case study was written. Based on current trends, the district is on track to save $120,000 during the shutdown. By comparing total electricity consumed this year to 2019 to 2020 occupancy levels during the COVID-19 extended shutdown, Coker used this data to forecast 2021 energy consumption and allocate budget for the following school year.
Like many school districts across the country, Wylie ISD was caught off guard by the need to quickly scale remote learning opportunities for its students. In a time where everything seems a bit turned upside down, Marcia proudly shares that the money the district has saved as a result of her modern energy management practices has already been reinvested to support remote learning. Marcia states that it is very powerful to be able to demonstrate fiscal responsibility to taxpayers and that by saving money from the utility budget, the district can now put additional chrome books into student hands.
