They’re the only Canadian team to make it into the finals. 

The 91�Թ� student chapter of the Canadian/National Electrical Contractors Association (CECA/NECA) is one of three finalists to compete at the 2016 Green Energy Challenge in Boston this weekend.

The students from 91�Թ� Engineering will compete against teams from Iowa State and the University of Washington. The final three were selected from 14 proposals.

The 91�Թ� team partnered with 91�Թ� Schools (UTS), a Grade 7 to 12 university preparatory school in downtown Toronto, to design an energy efficiency upgrade, including a small-scale photovoltaic system that would serve as a teaching and learning tool for students.  

“We selected UTS because it is an aging building that uses older lighting systems and could benefit greatly from an upgrade,” said Dmitri Naoumov of civil engineering, the team’s project manager. “The school is also planning a major renovation, so our proposal could help to inform the energy needs and improvements.”

Competing alongside Naoumov are Matheos Tsiaras, Ernesto Diaz Lozano Patiño, Greg Peniuk, Mackenzie De Carle and Nataliya Pekar – all from civil engineering – and chemical engineering's Arthur Leung and Claire Gao.

Their design includes detailed technical solutions for classroom lighting retrofit, integrated window treatments and the design of a rooftop 4kW photovoltaic solar array, which all meet the unique needs of the building and the climate in Toronto.  By upgrading the lighting system to use lower wattage bulbs, using occupancy sensors and installing light shelves that regulate daylight, the team determined that UTS could reduce its annual energy consumption by up to 125 MWh, or enough to light 10 typical homes.

"The lighting in the rooms was below the recommended levels for classroom learning,” said Naoumov. “By increasing the light in classrooms, we are helping to create an environment more conducive for students and teachers.”

UTS is eager to incorporate the students’ energy efficient and technologically savvy infrastructure into its daily operations. Because many Toronto public school buildings are showing their age, this could serve as a model for future upgrades across the city.

“UTS is an Eco School and we aim to reduce our environmental footprint and energy costs,” said Philip Marsh, vice-principal of UTS. “The team’s analysis and understanding of how to improve the efficiency of our building was impressive. We see the proposed roof solar array as a viable design option for the future.”

Competing for the first time at the Green Energy Challenge in 2015, the 91�Թ� team placed fourth with its lighting and back-up power retrofit proposal for the Good Sheppard Ministries shelter in downtown Toronto. Although the project did not win them a spot at the convention, Good Sheppard Ministries is currently implementing their design throughout its facility.

CECA/NECA brings together electrical contractors across the country to share experience and advice. Established in 2014, the 91�Թ� chapter extension is the first of its kind in Canada. Its goal is to bridge the gap between contracting and engineering and engage students with first-hand, applied experience. In addition to pitting their design savvy against groups at other North American universities, the group hosts networking and social events and connects students with scholarship and job opportunities.
