Overview 1. Introduction to energy efficiency 2. Steps to implementing energy efficiency 3. Energy use in buildings and benchmarking 4. Energy audits 5. Energy-saving opportunities by system 6. Q and A
What is Energy Efficiency? • Using less energy to perform the same function • Technology-driven
How to Save Energy • Behavioural Change – Free / low cost – May compromise comfort or convenience • Technological Change – Preserves comfort and convenience
Why is Energy Efficiency Important? • Triple Bottom Line – Saves money ( Profits ) – Benefits environment ( Planet ) – Improves health and well- being ( People ) Source: Capturing the multiple benefits of energy efficiency, IEA
Why is Energy Efficiency Important? Reduces emissions and saves money Energy Efficiency Improvements Source: Pathways to a low-carbon economy (version 2), McKinsey & Company

Why Do An Energy Audit? What retrofits should you prioritize? Lighting? Old Windows? Old Furnace?
Energy Audit Steps 1. Bill Analysis: 2 – 3 yrs. of energy bills 2. Site Visit: Survey building systems 3. Analysis/Research: Detailed report 4. Presentation of Findings
Results • Building energy use baseline: Critical first step • Energy Conservation Measures
Green Leagues • Burnewood Community League • LEDs, Condensing Furnace, Door Seals, Attic Insulation • 44% electricity savings post retrofits • Solar was not suitable • Blue Quill Community League • LED’s, Sensor Light Switches, Outdoor Rink Lights, Exit Lighting • 75% electricity savings post retrofit • Solar added as second phase
Energy-Saving Opportunities (ESO) Re-commissioning Controls & set points Behaviour Efficiency upgrades Maintenance
Energy Saving Examples • Refrigerator always running – Maintenance
Energy Saving Examples • Furnace fans always running – Controls
Energy Saving Examples • Boiler and thermostats controls – New condensing boiler programmable thermostats –
Energy Saving Examples • Aged AC line insulation – New Insulation and PCV jacket
Energy Saving Examples • Damaged weather seal • Missing door closer
Lighting • 15% to 30% of energy use in commercial facilities • First area to focus Evansdale Community League • Short paybacks • Principles for reducing energy use: – Reduce illumination levels – Improve lighting system efficiency – Curtail operating hours – Take advantage of daylighting
Lighting Incandescent to LED • – Exit signs T12/T8 fluorescent to T8-LED • Sensors • – Occupancy – Daylight Lighting control • Behavioural •
Jeremy’s Lighting Retrofit • Initial investment: $265 • Annual Savings: $124 • Simple Payback: 2.1 years
HVAC – Low Cost Opportunities • Poor maintenance = Low efficiency • Temperature set points, Get a smart thermostat • Zone control
HVAC – Equipment Upgrades • Variable speed fan motors • Heat recovery ventilators • Upgrade HVAC unit to more efficient model
Domestic Hot Water Heat recovery • – Marian Centre reduces 51% of daily hot water energy • Solar thermal system – When is hot water used? • Gas over electric heating – Electric 4x more expensive • Insulate pipes and tanks – Reduce thermal loss
Plug Loads • ENERGY STAR rated appliances – Freezers – Refrigerators • Avoid unnecessary electric heating – Commercial coffee makers • Reduce phantom loads – power bars, timers Perform your own plug load audit
Building Envelope • Goals: – Reduce heat exchange between building and outside – Control solar and internal heat gains
Building Envelope Infrared Thermography
Building Envelope • Replace old weather stripping • Seal cracks and air gaps • Add insulation – Roofs – Basements • Energy efficient windows – Triple pane, low-emissivity
Water Conservation • Taps, toilets, showerheads – Low flow, Low flush • Sensor taps – Reduce run time, hygienic • Hot water energy savings
Summary • Significant opportunity for energy efficiency – Conserve energy, save money, and reduce GHG emissions • Energy audits – Set energy goals and plan for the future – Benchmark building energy use • Energy-saving opportunities • Energy Transition Ambassadors – Inspire your community

Cloverdale Community League Sustainability Renovations Energy 101 EFCL Community Sustainability Workshop Series November 6, 2018
Agenda Timeline Overview of Cloverdale Community League Green Energy Retrofit & Renovations Challenges Learnings Impact Q & A
Timeline June 2015 – engaged Dandelion Renewables to conduct basic energy assessment report focused on electricity and natural gas consumption. Findings: electrical consumption could be reduced by 28% and natural gas consumption could be reduced by 31% June 2016 – engaged Carbon Busters to conduct ASHRAE Level II Energy Assessment November 2016 – presented report to Cloverdale Community League membership. Motions to proceed with upgrades (83% in favour) and replace deck (100% in favour)
Timeline (continued) January to March 2017 – submitted grant applications Approvals and funds received between April 2017 and March 2018 Construction on ‘as funds available’ basis from May 2017 to present Construction scheduled around hall activities
