Limestone District School Board

The Energy Systems Engineering Technology (ESET) program at St. Lawrence College provides 3rd-year students with the opportunity to conduct a professional energy audit of a commercial property. The project spans two semesters and since 2008 the ESET program has audited 20 Limestone Schools.

In 2008, ESET students conducted a professional energy audit where the goal was to perform an in-depth analysis of energy (electrical and heating) usage of Winston Churchill Public School. Effectively creating a baseline of energy consumption that was then modelled in RETScreen, an energy modelling software, used to analyze possible retrofits (building energy efficiency upgrades). Taking a holistic approach allowed the students to model and test various retrofit options to determine the most impactful and cost-effective solutions. This is known in the energy industry as the low hanging fruit.

Implementing cost-effective solutions as recommended by these energy audits allowed

Sir Winston Churchill Public School to:

● Reduce CO 2 Emissions

● Reduce Energy Usage

● Reduce Operational Cost
