Purpose: Address goal or action in Corporate Energy Management Plan Respond to legislation Executive Summary: The purpose of this report is to update Council on Burlington s facilities energy management activities and utility consumption in This report includes detailed facility energy and water consumption data for 2015 compared to The method of presenting the data is consistent with Ontario Regulation 397/11 which requires municipalities to report and publish energy consumption data and greenhouse gas emissions. Background: In 2009, Council approved a corporate energy policy (CSI-3/09) which provides guidance and direction to staff on the development and implementation of a comprehensive corporate energy management program.

2 Page 2 of Report CW In 2009, the Green Energy Act and Green Economy Act (GEGEA) directed the broader public sector (municipalities, universities, schools, and hospitals) to develop and report their energy conservation and demand management plans. Specifically, Ontario Regulation 397/11 Energy Conservation and Demand Management Plans enacted in August 2011, mandates: Completion, publication and submission to the Minister of Energy of Burlington s corporate energy consumption and greenhouse gas emission template for 1 year of operation (Jan 2011 to Dec 2011) by July 1, 2013 and annually thereafter (completed Mar 2013 CSI-06-13); Development and publication of a detailed energy conservation and demand management plan with targets approved by senior management by July 1, 2014 (completed Apr 2013 CSI-09-13); and By July 1, 2019 and every 5 years thereafter publish an update to the original plan that reviews measures implemented, their actual results and forecasted impacts of planned measures, and any changes made to achieve our targets. Energy conservation typically means reducing the total amount of energy consumed (kwh of electricity and m 3 of natural gas). Demand management refers to reducing the rate of electricity (kw) required at any one time especially during peak periods. These are designed to help manage Ontario s total use and peak demand for electricity. Discussion: The City of Burlington has a significant energy and environmental impact associated with its own operation. The City s Environment and Energy Services staff ensure the City is identifying, implementing and reporting on opportunities that reduce the City s direct environmental footprint, reduce current and future operating costs, and generate revenue. A number of energy management initiatives were undertaken and completed in 2015, including: Upgrading and improving building systems efficiency; Developing a corporate culture focused on behaviors which improve efficiency and management methods; Analysis of consumption and demand to highlight and report on anomalies and implementation of corrective measures; and, Implementation of a new energy management system to track cost and usage as well as identify and analyze utility abnormalities.

3 Page 3 of Report CW Strategy/Process The following section highlights initiatives that were initiated and/or implemented in For a list of energy management initiatives completed in 2014, please refer to report CW New Corporate Energy Tracking System: Over the past year Capital Works has implemented, a new web-based Buildings Energy Management System (BEMS) to track, monitor and report all City-owned buildings energy performance including electricity, natural gas, and water. The new BEMS, is used to provide facility supervisors, energy coordinator, sustainability coordinators and system engineers with insight into building energy consumption and cost data. The system is able to track ongoing energy usage based on utility bills, and assess the data needed to identify opportunities for energy conservation improvements, whether operational or capital. The system allows us to compare like buildings and groups of buildings to identify lower performing facilities. This measurement and reporting strategy will continuously inform and encourage staff to conserve energy in a format which is in compliance with Ontario Regulation 397/ Corporate Building Automation System (BAS): The BAS has been operating and helping save energy and operating costs since Staff have received annual training and support since implementation in In 2015, more detailed training was given to staff to understand the inner workings and programming of the system so that changes could be made in house rather than contracted out. This type of detailed training allows city staff to identify system problems as well as resolve them much faster than in previous years. By reviewing the information provided by the BAS, operators, supervisors and coordinators can identify and diagnose operational problems early, without having to send a technician to locate

In 2015, building automation systems were improved at Paletta Park and Aldershot Pool. Addtionally in 2015 a number of spare parts for the building automation were obtained to minimize down time during any system failures. 3. Pool Facility Energy Competition: In 2015, Capital Works initiated an energy competition at four Parks and Recreation Pool Facilities to inspire staff and users to reduce their operating costs and their environmental footprint by challenging them to improve their facility s energy performance by 10% from October 1 st to December 1 st, 2015 compared to the same period in The competition was supported by an energy management training workshop for 15 participants to increase their understanding of energy conservation and to introduce and provide resources that will support them during the competition. The competition was successful in achieving accumulated energy consumption savings of 11%. The results translate to 160,000 ekwh (electricity and natural gas combined) and $8,300 in savings. The Award presented for this energy competition went to: Collective Team Facility Award: Angela Coughlan Pool facility team was successful in reducing their equivalent energy consumption by 21% compared to the previous year. Central Arena De-Ox System: In 2014 Capital Works installed a pilot De-Ox Ice Making System at Central Arena that allows oxygen to be removed from the water resulting in reduced refrigeration costs, natural gas and electricity consumption, and decreased labour costs. The De-Ox system saves energy by not requiring Zamboni water to be heated and subsequently reduces the cooling load on refrigeration plant. Additionally, the De-Ox water produces ice that is harder, faster, more resilient to cuts and runs, and has greater clarity to show painted lines and logos in the ice. Additional value can also be seen in the reduction of carbon emmissions from lowering our natural gas usage. We are now able to evaluate the pilot project since it has been installed for a full season at Central Arena. Savings have been verified and very closely match the previous payback estimates indicated below. Measured savings achieved are approximately $5,800 per year, in natural gas alone. This system will now be considered for use in other ice rinks.

LED Lighting and Lighting Control Retrofit Projects: Over the past few years, Capital Works has been upgrading indoor and outdoor lights on buildings to enhance lighting levels and achieve greater energy savings using LED technologies as well as control strategies to further minimize energy use in lighting systems. Staff take advantage of funding opportunities to assist with larger capital investment projects. The following lighting retrofit projects were initiated in a.

Haber High Volume Low Speed Fan: High volume low speed fans, otherwise known as destratification fans, can be used to slowly and constantly push warm rising air back down to ground level to lower heating costs. The fans rotate at a low speed to reduce unwanted breeze and create a more comforable and energy efficient environments. Project Cost Annual Energy Incentive Simple Payback Project Status $9,200 $3,000 $1, Years Completed 6. Solar PV Installations at Various City Facilities In 2015 the City entered into rooftop lease agreements with Ontario Solar Provider (OSP) and QPA Solar Inc. for FIT (Feed in Tarrif) contracts with the IESO (Independent Electricity System Operator) at 14 city facilities. Applications for contracts have been submitted and we expect to receive word on their status from the IESO sometime in Q2 of OSP and QPA will own, operate and maintain the systems and Burlington will receive rent for 20 years for the roof area being used. The City will receive income from previously unused roof space, help reduce emissions and contribute to a greener environment, pending IESO approval. Next Steps: Below is a list of next steps staff is taking to ensure that the City of Burlington continues to be a leader in energy management and conservation 1. Real Time Energy Metering By Implementing real time energy metering, supervisors as well as operations staff are able to see how equipment operation affects the building s energy demand curve and are able to adjust equipment operation to mitigate spikes in demand which increase energy costs. Troubleshooting of problems and identification of equipment issues becomes easier and faster and reduces any overages that may occur as a result.

7 Page 7 of Report CW Operator and Supervisor Energy Displays Displays or Dashboards within the new energy management system will give front line staff better accessiblity to energy data as it becomes available; this coupled with building automation system trending and regular energy updates on their facility will also assist in identifying when buildings have exceeded their expected energy use and/or cost. 3. Advanced Pool Filtration Controls Pool controls will be installed in 2016 at the city s indoor pool facilities to reduce the amount of energy used by their pump systems based on monitoring water clarity and adjusting pump speed to an appropriate level to maintain a clarity set point. 4. Lighting Upgrades As lighting systems come to the end of their expected lifespan they are constantly being upgraded to LED fixtures to reduce energy usage as well as increase lifespan and quality of light in the areas. Upgrades are currently being reviewed at Appleby Ice Centre, Waterfront Centre, and Roads and Parks Maintenance Civic Operations Centre, as well as exterior lighting fixtures at a number of locations. 5. HVAC Upgrades Upgrades to HVAC (heating, ventilation and cooling) systems are an excellent way to decrease energy consumption as well as improve air quality in facilities. Upgrades are currently being designed for Tansley Woods Community Centre as well as the Roads and Parks Maintenance Civic Operations Centre. Building Performance Charts The following charts provide Burlington s 2015 utility use by building categories. Individual building performance values are included in Appendix A. Chart 1: Electricity Consumption The overall electricity consumption increase can be attributed to the completion of the mountainside recreation centre expansion as well as programming increases at arena facilities. Due to improvements in equipment operation, control and monitoring, in addition to energy efficiency measures as detailed in the previous section, a reduction in most other areas can be seen. The overall electricity increase in 2015 is approximately 284,867 kwh or 2.0% compared to 2014.

This increase can be attributed to a number of causes including additional training for zamboni operators, additional irrigation systems as well as higher use of irrigation systems and building expansions. The installation of several splash pads with a once through water system which reduces the amount of treatment required has also increase the amount of water used in the others category by a significant margin but overall reduces the operating and maintenance costs of those same splash pads.

Due to the implemenation of a new energy management system we are unable to do so for this report. However this will be included in next year s report detailing energy consumption. Appendix B does summarize utility cost on a site by site basis. This cost includes account charges, delivery, storage and various other components of the utility billings. The City of Burlington bulk purchases electricity and natural gas through the Halton Purchasing Cooperative Group (HPCG) which provides leverage. This has helped reduce the average cost of utilities for some energy accounts and provide price stability/savings. Staff continues to monitor and manage utility use and purchase contract options to obtain best value for the City. The table below summarizes overall costs in each utility across facilities as well as parks and open spaces.

The Energy Management Committee is a continuous prime focus every year and has the following objectives: To promote the wise use of energy within the municipal operating areas by providing department managers with information about available rebates and opportunities for reduced operating costs; To prepare action plans for opportunities that demonstrate potential for capital cost savings and reduced operating costs through energy reduction and to bring these forward for review as part of the budget process; To use the money saved through energy rebates to pay for facility audits that will identify further energy-saving opportunities and cost savings and pay for other energy savings and sustainability projects. In 2016 the committee will review the 2013 Corporate Energy Management Plan in advance of an updated Corporate Energy Management Plan that will need to be prepared in 2017 for completion and approval in This will include review of the goals set out in the 2013 plan and how close the City is to achieving these goals.the new Energy Management System is currently being configured to be able to easily report specifically against the goals outlined in the 2013 Corporate Energy Management Plan. A related initiative in the new Strategic Plan will also be considered: The City will develop and implement a plan to make city operations net carbon-neutral. Environmental Matters: Corporate facility assets are a source of greenhouse gas emissions, directly and indirectly because of natural gas and electricity consumption. However, due to the phasing out of coal fired generation plants, greenhouse gas emissions from the electricity sector have been minimized at a provincial level. The city continues to

11 Page 11 of Report CW implement energy conservation projects and investigates new and renewable technologies in order to mitigate greenhouse gas emissions. The following charts describe Burlington s equivalent greenhouse gas (GHG) amounts for facilities. There was approximately 211 tonnes of reduction in GHG emissions in 2015 or 4% saving compared to Tonnes 4,000 3,500 3,000 2,500 2,000 1,500 1, Greenhouse Gas Emissions - Facilities (by source) Electricity Natural Gas ,028 3, ,064 3,383 The following chart shows greenhouse gas emissions from City operations, including streetlights/traffic signals, fleet vehicles and off-road equipment from 2012 to Future emissions from streetlights should decline once the LED conversion project proceeds. However, emissions from light duty vehicles continue to climb. A review of the Green Fleet Transition Strategy approved in 2008 is pending in which the vehicle procurement process will be reviewed, among other actions, in an effort to improve efficiency and reduce emissions.

12 Page 12 of Report CW Public Engagement Matters The City continues to participate in energy conservation events such as Earth Hour on an annual basis. Staff ensure unnecessary lights and equipment in facilities are turned off during the event and posters advise visitors that the City is participating in Earth Hour. During the pool facility energy competition, posters were again displayed to advise visitors about the competition and included actions that everyone could participate in to help conserve energy, including taking showers before entering the pool. The Take Action Burlington blog is also used to engage the public in energy conservation initiatives. Conclusion: Although there was an increase in usage in some areas, this can generally be attributed to an increase in service to the public. Through mitigating the increase of energy use as well as increasing services, the City of Burlington continues to be in a position of leadership in municipal energy management. Progress was made in 2015 towards meeting the goals set in the Corporate Energy Management Plan. Through staff engagement, implementation of pilot projects and energy conservation projects, as well as metering and energy tracking, city staff continue to work towards those goals and create an energy and environmentally conscious culture. Since 2013, the Province of Ontario through Ontario Regulation 397/11 mandates municipalities to comply with annual energy consumption and greenhouse gas reporting requirements starting in This report illustrates that Burlington will once again be able to satisfy the legislative requirements of this regulation.
