2 Corporate Sustainability Initiatives Environmental Master Plan Approved by Council May 28, Strategic Plan Good Government Move & Connect Smart Growth Strong Communities Conservation & Demand Management Plans ON Reg 397 July 1 st Reporting 2

3 Elements of the Energy Program Tracking, Profiling & Performance Procurement of Electricity & Natural Gas Commissioning of Existing Buildings Programs & Audits Building Automation System (BAS) Management Project Business Cases and Justifications Capital Project Delivery Retrofits (lighting) Renewable Energy Projects Energy Management Training for Staff Measurement and Verification Rebates and Incentives Consulting 3

4 Utility Cost $25,000,000 $20,000,000 $15,000,000 $10,000,000 $11,727,041 Total Utility Cost $16,174,967 $14,422,198 $13,511,010 $17,401,099 $20,170, vs Energy used increased by 1% Buildings area increased by 7% 3% increase in street lights New Subdivisions Rate Increase: Electricity 14% Water 13% $5,000,000 $

5 Energy Capital Funding Capital Blanket funds request as part of City s budget process Tax based Gas Tax Internal borrowing In order to use these funds each project shall be justified (CEM Process) 5

6 Brampton Transit - Clark Brampton Sandalwood Transit Built in 1972, Four expansions Total Area : 145,000 Sq. ft $500,000 utility Cost 2015 (8 th ) Built in 2008, expansion in 2016 Total Area : 265,000 Sq. ft $730,000 utility Cost 2015 (3 rd ) Bus Garage - Heated Bus Repair Area Air conditioned Administration offices Diving lounge and Control room Bus wash and cleaning area - Heated Fuel Bay Heated Parts Storage Ourdoor parking 24-7 operation Unionized environment 6

7 Brampton Transit 2010 Make up air units and rooftops units Exhaust Fans Unit Heaters, Radian Heat Exhaust Control Ventilation HID (400 Watts) and Fluorescent fixtures (T8) CO/CO2/NOx sensors, local thermostat control BAS for office Spaces 7

8 Energy Initiatives Since 2011 Operational Changes Low Cost Measures Capital Measures Future plans 8

9 Energy Initiatives - Operational Changes Lower garage winter temperature setting to 15 from 18 Keep the door close in winter and open for natural cooling/ventilation Optimize current control Optimizing HVAC (Lead and Lag operation) 9

10 Energy Initiatives - Cont. Low Cost Measures Building Re- Commissioning Calibration of CO Sensors Occupancy Sensors Building Envelope Assessment 10

11 Energy Initiatives - Cont. Capital Improvement Garage LED lighting and control (2015) New BAS system (2016) MicroFIT (mostly for awareness and PR) 11

12 Energy Initiatives - Cont. Under Installation: New BAS Outdoor LED Lighting for parking lot and wall packs (100+ fixtures) Planned for : Destratification Fans High speed overhead doors De- commissioning existing unit Heaters (25) with new control there is no need for them High efficiency boilers 12

13 Sandalwood Transit Make up air units and rooftops units Exhaust Fans Unit Heaters, Radian Heat Exhaust Control Ventilation HID (400 Watts) and Fluorescent fixtures (T8) CO/CO2 sensors, local thermostat control BAS Major flaw in mechanical design Overdesign Lighting 13

14 EUI [ekwh/ft 2 ] 12-Month Rolling Eenergy Use Intensity Actual Adjusted for Weather

15 Energy Initiatives Since 2011 Operational Changes Lower garage temperature setting to 15 from 18 Disconnect extra light Commissioning Change control strategy for garage space Reduce the operation of the exhaust fans by stages High Ventilation Low Ventilation Purge 15

16 Operational Changes - Cont. Reduce the energy consumption of the MAU Systems 16

17 Operational Changes goal: Reduce the energy consumption of the EX_FANS Units 17

18 Energy Initiatives - Cont. Low Cost Measures Adding more CO and NOx Sensors Occupancy Sensors Building Envelope Assessment 18

19 Energy Initiatives - Cont. Capital Improvement Garage LED lighting and control (2015) Upgrade BAS system MicroFIT (mostly for awareness and PR) HVLS Fans 19

20 Energy Initiatives - Cont. Under Installation: Outdoor LED Lighting for parking lot and wall packs (100+ fixtures) Planned for : High speed overhead doors Air Curtin for Bay doors 20
