This webinar is part of a series of webinars on District Energy Systems. In this webinar, we will learn more about the Energy Services Acquisition Program (ESAP) in Ottawa, which modernizes the energy system of 80 buildings to cut greenhouse gas (GHG) emissions and save money. The system connects to four energy centres using more than 14 kilometres of underground piping and will use a district energy system (DES). We will learn more about the regulations, technology used, barriers &benefits and lessons learned thus far.
