Michael Rasmussen, the energy, environmental and emergency manager for GCCISD, updated trustees on the progress of a project to improve energy and conservation efficiency in the district.
Started in April, the project is projected to save more than $31 million over 15 years.
Three projects are complete: new controllers for boilers, coating of air conditioning coils and plug load controls for high-usage equipment such as copiers.
Sports lighting improvements are 80% complete, with all football fields already finished.
Improvements to heating, air conditioning and ventilation controls are only 15% complete. Since this requires extensive planning and work in each district building, it will be the last one finished, Rasmussen said.
Estimated completion of that project is October 2020.
