Senior Jin Chen and Junior Yana Lozina analyze graphs of the Performing Art Center’s energy consumption for an ongoing sustainability project launched by the Physettes’ Club. “The PAC project is about using school data on energy consumption to establish a future plan of more sustainable energy usage. We will introduce energy-efficient products into the school, such as LED lights and motion sensors. Also, we will adjust the time schedules of the lights in the PAC and monitor its progress over time,” said Chen.
