trca.on.ca/mmc The Town Hall Challenge Continues – Finding the Big Savings in your Town and City Halls
Technical Panel: Daniela Paraschiv, City of Mississauga Joel Arthurs, City of Toronto Tom Darlow and Cristina Guido, Town of Caledon
Moderated by Ian Jarvis, Enerlife Consulting Inc. Nov 16th Pre-Forum Webinar Agenda
The Town Hall Challenge • The Big Picture – Town/City Halls across Ontario • 2016 vs 2012 performance • 2016 savings potential and 2017 savings leader board • Finding electric baseload savings – the power of interval metering • Mini-Audit results and action plans arising
Savings Potential for Town and City Halls across Ontario Total Electricity Savings Potential 43,989,941 kWh/year
Total Gas Savings Potential 1,979,082 m3/year

Gas WhereElectricity the Components Big Savings Are Strategic Conservation Planning - The Town Hall Challenge Tackling Electric Baseload Savings TheElectricity Power Components of Interval Metering
• Your profile is actual, whole-building electricity use coming directly from your LDC • It has not been adjusted for non-standard loads such as computer rooms, equipment or heat pumps • The aim is to reconcile interval profiles with actual base electric loads (mostly lighting, HVAC motors and equipment) UncoveringElectricity Components the Hidden Savings

Fan Motors • Max – rebalancing, VFD control, fixing static losses • Min – scheduling, occupancy control Lighting • Max – LED replacement, fixture retrofits, occupancy and photo-controls • Min – scheduling, fixing relays Heating Pump Motors • Max – right-sizing, VFD control • Min – scheduling Equipment • Max – replacement, removal • Min – scheduling, controls, behavioural change ElectricElectricity Baseload Components Assessment Reports – distributed June 2017 FindingElectricity the Components Energy Saving Opportunities
• Measure loads and compare with good practice standards for: • lighting (0.65 W/ft2 fluorescent, 0.35 W/ft2 LED) • fan motors (0.3 W/ft2) • Document equipment loads, estimate or test kW • Review scheduling of lighting and HVAC equipment during unoccupied and weekend periods MeasuringElectricity Components Loads – Mini-Audit
• Template allows you to record and calculate your daytime (max) and overnight (min) base electric loads (lighting, fan motors and equipment) • Comparing the Watts/ft2 between higher users and better performers should uncover the retrofit and operational savings opportunities for each individual building MeasuringElectricity Components Loads – Daytime Demand
