1. EXHIBITION PLACE PROMOTING Sustainable Development Environmental Initiatives Leading Edge Green Technologies & Practices • Event: A Brighter Tomorrow,: Advancing LED Lighting in Public Housing and Private Residential Towers in Ontario • Date: October 15, 2013 • Location: Daniels Spectrum Building

2. ENERGY EFFICIENT INITIATIVES------ Exhibition Place is committed to Energy Conservation and have implemented key energy efficient initiatives over the years. Namely; • Tri-Gen – Generates 3 forms of secondary electricity (electricity, space heating, space cooling) • Solar Photovoltaic (PV) generation plant on the roof of Horse Palace, East Annex and Better Living Centre – These are estimated to generate more than 700,000 kWh per year • Wind Turbine – This has generated 6.2 million+ kWh of electricity since 2005 • Back Pressure Steam Turbine - Uses waste heat in the form of steam to generate electricity. As a result, Exhibition Place can decrease its reliance on the electrical grid by an estimated 305,586 kWh per year.

3. Energy Efficient Initiatives------ • Green Roof - The 2,500 sq. ft. meadow on the roof of the Horse Palace and 22,000 sq. ft. meadow on the North Extension is just one part of the City’s goal to green just 6% of rooftops which will reduce summer air temperatures by 1 to 2°C. Cool Roof - Expected to save 45,000 kWh electricity per year • Geothermal Project – Installed in 2008, has reduced annual electricity use by 44% and natural gas by 98%. • Lighting Retrofits - The installation of energy efficient ballasts and lamps in Direct Energy Centre's main Exhibit Halls and public spaces results in an annual reduction of 2.3 million kilowatt hours of energy use. • LED Streetlights - LED streetlights at Exhibition Place dramatically reduces city lighting costs and cuts greenhouse gas emissions.  Each streetlight comprises 117 LEDs to produce the same intensity as a conventional streetlight. LEDs, however, use 50% less electricity and last 5 times longer.

4. Energy Efficient InitiativesLED Pathway Lighting------ BACKGROUND • LED Pathway Lighting was a project of the LightSavers program. • The Toronto Atmospheric Fund (TAF) founded LightSavers in 2008 • The LightSavers project aims to accelerate deployment of advanced lighting technologies – Light Emitting Diodes (LEDs) and smart controls – in order to reduce energy use and greenhouse gas emissions.

5. LED Pathway Lighting------ BACKGROUND cont’d • In March 2012, LightSavers entered its third phase: the creation of a national market consortium that aims to step up the adoption of LED lighting and smart adaptive controls in certain general illumination applications across the country. • This field test was carried out by Exhibition Place and its consultants and contractors, with technical assistance on monitoring and evaluation from the TAF

6. LED Pathway Lighting------ • This was a Pilot Project consisting of retrofitting lighting along a pedestrian pathway that extends along almost the entire south side of the Exhibition Place campus. • The purpose of the project was to evaluate whether the LED fixtures could be a viable and energy efficient alternative to the HPS pathway and parking lot fixtures commonly deployed in Toronto and across North America • The project involved replacement 58 high pressure sodium pathway and parking lot fixtures with 50 new LED fixtures manufactured by LUMEC Lighting

7. LED Pathway Lighting------ • The most significant innovation is that all of the fixtures are equipped with occupancy sensors to dynamically adjust the light levels based on user needs. • It’s believed that about 70% of the time the lights will be on the low setting, using just 10 watts. The net result is a projected total energy savings of 85%.

8. LED Pathway LightingSite Description------ • The pilot site is a pedestrian pathway that extends along almost the entire south side of the Exhibition Place campus, beginning right beside the iconic wind turbine, and traveling east towards Nunavut Road. • The original lighting system consisted of 58 High Pressure Sodium fixtures which used 130 watts each, required bulb changes every few years, and cast a foreboding orange glow. • The new lighting system uses fifty LED fixtures manufactured by Philips Lumec • Thirty-eight (38) fixtures located on the west end of the path consume about 40 watts and 12 fixtures located on the east end of the path consume 90 watts. • Each of the respective wattages emit the same high quality white light similar to that of moonlight in colour.

11. LED Pathway Lighting------ KEY FINDINGS • Average illuminance in the Pathway area was maintained in compliance with IESNA pathway lighting guidelines. • 70% of the time the lights are on the default low setting, using just 10 watts, the net result is a total energy savings of 77%. • Depreciation in illuminance over eight months in one of the test areas was measured at 14.1%, which was significantly higher than anticipated. There was no observable depreciation in illuminance in the second test area. It must also be noted that the light meters are only accurate to +/-5% • The new LED fixtures are projected to result in an 85% reduction in long-term maintenance costs

12. LED Pathway Lighting------ KEY FINDINGS cont’d • The LED fixtures are projected to pay for themselves through energy and maintenance savings within 9 years • The new LED luminaires are exceeding required light levels and providing excellent uniformity. • The long-term financial benefit of the LEDs depends on whether the fixtures meet the manufacturer claimed life-expectancy of 70,000 hours (~16 years).

14. LED Pathway LightingConclusions------ • It appears that the LUMEC Life- LED pathway lights do a credible job of replacing conventional High Pressure Sodium technology at considerable energy savings. • Average illuminance on site was increased or maintained while power consumption was reduced by 77%. • This difference is partly attributable to the differences between HPS and LED source technology, but a large portion is attributable to the occupancy controls. • Those considering implementing LED technology should bear in mind that the energy savings and financial benefits of replacing conventional pathway lighting fixtures are highly dependent on the baseline efficiency of the specific fixtures being replaced.

15. How are Retrofits financed?------ • Retrofits are financed based on availability of Capital vs. Operations Savings. • Financing comes from a number of sources: • Internal Capital Program • Operations Expense • Private Sector Partnerships Funding • City of Toronto Programs (TAF, BBP, OPA, FCM, Nrcan, etc.) • Typically for non end of life retrofits, we look for an ROI of 8 years.

16. Our broader plan for Lighting Retrofits------ • Our plan is driven by 3 factors: • Sustainability • Operating Efficiencies • Public Safety • Firstly, with the use of LED fixtures, the demand for electricity is reduced, thereby reducing: • Greenhouse gas emissions from electricity production • Operations expenses are reduced from lower utility bills • Reduced labour cost in changing out fixtures • The considerations must not impact public safety.

17. Our broader plan for Lighting Retrofits------ • Our broader plan includes eventually changing out: • All street lights from HPS to LED • All parking lots lights from HPS to LED • All general lighting • All event lighting

18. Our Primary Barriers------ • Our primary barriers are: • Availability of Funding – As with most programs, we still have to come up with 50% of the funding. • Technology – This is also a barrier is comes cases, i.e. Our search light replacement fixtures

19. Key Energy Efficiency Success Story------ • Successfully tested the application of Smart Control LED Pathway Lighting with: • Less operating cost • More energy efficiency and; • Produced acceptable level of safety to the public.

20. What Motivates Us?------ • Some of the key things that motivates us are: • New Technologies & Application • Sustainable Development • Customer Satisfaction • Increased Operating Efficiencies
