Efficiency Engineering (EE) recently received the 2019 Award for Engineering Project of the Year in the Sustainability Engineering Category, presented by the Ontario Society of Professional Engineers Hamilton/Halton Engineering Week Committee. The award was for work performed at the Derry Sports Complex PERC (Primary Emergency Response Centre).
In 2016, Milton Hydro approached EE to look at options for the Town of Milton’s sports complex. As a Primary Emergency Response Centre for the Town, the facility that will need to stay open in the event of any emergency (which could include an extended electricity power outage).
Our recommendation was to install a combined heat and power (CHP) system to deliver electricity, heating and cooling to the building. During normal operation, the CHP system will supply up to 400kW of power (expandable to 500kW). The waste heat from the system being used to offset heating, domestic hot water and cooling (through two absorption chillers). During a power outage, the CHP system will continue to operate. It will be supplemented by an additional 200kW of back-up generation as well as the existing solar PV system. Building demand is actively managed through a building automation system to be below the available power.
In the fall of 2016, EE was hired to undertake the detailed design of the recommendations. This included getting all of the necessary connection assessments (through Milton Hydro and Hydro One) as well as performing the mechanical and electrical design. , In addition to the design, we were responsible for coordinating with other trades installing the Solar PV system, tendering the project and construction management. We are currently performing the measurement and verification to show that the system is operating as expected.
We, at Efficiency Engineering, are proud of our work on this project and significant effort was undertaken to ensure that the Derry Sports Complex has a combined heat and power system that delivers a positive return on their investment. The compelling successes of this project being significant utility savings, a significant greenhouse gas reduction and emergency backup capabilities.
