Why Do An Energy Audit?

What retrofits should you prioritize? Lighting? Old Furnace? Old Windows?

• 2. Site Visit: Survey building systems
• 3. Analysis/Research: Detailed report
• 4. Presentation of Findings

Energy Audit Steps

1.Bill Analysis: 2 – 3 yrs. of energy bills

Results

• Building energy use baseline: Critical first step
• Energy Conservation Measures

• 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

• Variable speed fan motors
• Heat recovery ventilators
• Upgrade HVAC unit to more efficient model

HVAC – Equipment Upgrades

• 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

Domestic Hot Water

Plug Loads

Perform your own plug load audit

• ENERGY STAR rated appliances

– Freezers – Refrigerators

• Avoid unnecessary electric

heating

– Commercial coffee makers

• Reduce phantom loads

– power bars, timers

Building Envelope

• Goals:

– Reduce heat exchange between building and

• utside

– 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

Carbon Busters Report Highlights

 Examined physical condition of building envelope, systems, maintenance procedures  Examined electricity & natural gas bills  Identified opportunities to reduce carbon footprint & opportunities to reduce or eliminate energy costs & fixed utility costs (ASHRAE Level II audit)  Presented wide range of potential retrofits & upgrades expected to yield positive IRR and/or minimum emission reductions of 1 tonne of CO2e.
