OUR ENVIRONMENT Reducing physical footprint and boosting energy efficiency at 71 Rexdale Boulevard and 500 Commissioners Street As part of its Facilities Consolidation program, aimed at making better use of space at existing work centres, in 2016, Toronto Hydro completed the construction of the David M. Williams Centre. The new facility, located at 71 Rexdale Boulevard, is built on a former industrial brown-field site utilizing much of the original building’s structural steel and concrete. This new building has incorporated Toronto Hydro’s new building and facility standards, including the use of energy-efficient lighting and Information Technology (IT) equipment, low volatile organic compound (VOC) paints and carpets, standardized office furniture, and elimination 76 TORONTO HYDRO I 2016 CORPORATE RESPONSIBILITY REPORT of desk-side waste bins. More effective use of office space has resulted in approximately a 40% reduction in Toronto Hydro’s space utilization per employee relative to 2012. Key facts related to the David M. Williams Centre construction project: • Over 2,500 tonnes of concrete and 400 tonnes of steel were salvaged, reused and diverted from landfill • Re-used existing furniture: 171 filing cabinets; 13 manager office furniture sets (including desks and storage cabinets); 75 training room tables; approximately 340 employee desk chairs; cafeteria furniture (20 tables and 55 chairs); security office welcome furniture (four chairs and two tables); warehouse furniture (racking and shelving, 10 workstations and two supervisor office furniture sets); and 230 lockers. The company assisting Toronto Hydro with this office move diverted from landfill 62% of its waste furniture (recycled 66.3 tonnes of furniture and sold 19 tonnes) • A variable air volume air handling system combined with multi-staged direct expansion cooling and perimeter radiant heating ceiling panels provide optimal comfort conditions for occupants • A demand control ventilation system is used to maximize indoor air quality and air handling system efficiency • A Building Automation System that controls and monitors core building systems (HVAC, lighting, water supply, life safety systems & security etc.) help ensure safe working conditions and prevents business interruptions by identifying and addressing building related issues proactively • Dedicated parking spaces have been assigned for carpool vehicles Furthermore, the roof at the 500 Commissioners Street location was replaced. The replacement included the addition of better insulation. This initiative resulted in improved insulation, reduced heat loss and better utilization of HVAC equipment. The new roof reduced the load on the facility HVAC units and contributed to a drop in the 2016 natural gas consumption by 19% relative to 2014 values. Complementing the aforementioned initiatives, departmental metrics such as reduction of energy use, square footage and GHGs are monitored monthly as part of Toronto Hydro’s Operational Support Services scorecard. FACILITIES In 2016, total electricity consumption at Toronto Hydro facilities decreased by 20.6% and natural gas consumption decreased by 20.9% over 2014. The decreases can be attributed to the various energy efficiency initiatives undertaken by Toronto Hydro (see page 72 for further details). Line losses GHG emissions from line losses in 2016 decreased by 57% from 2014. This decrease is largely attributed to the lower provincial emission factor. SF6 fugitive emissions The total SF6 fugitive emissions increased by 65% in 2016 compared to 2015. This increase is believed to be due to a more accurate and comprehensive measurement methodology introduced in 2016. Reportable SF6 fugitive emissions increased by 39% over 2014 as a result of the change to the process for tracking SF6 gas inventory and equipment emissions (for details see Data Sources and Internal Data Assurance).
