Optimizing Energy Performance: RCx Programs Across Canada

Prepared by: Robert Greenwald, P.Eng., MBA, President Prism Engineering Ltd.

Introduction

Prism Engineering provides consulting services to address technical, behavioural and

• rganizational aspects of

Energy Management We design and implement cost effective approaches to address comfort, efficiency and reliability.

RCx Overview

3

Context

The total energy consumption of commercial and institutional buildings in Canada accounts for:

 12% of secondary energy usage  11% of our national GHG emissions

Based on NRCan’s 2013 Report, Energy Efficiency Trends in Canada 1990 to 2010

4

RCx Goals

Specifics of retrocommissioning:

 Optimizes energy efficient design features  Addresses equipment performance and system integration issues  Ensures building staff can effectively

• perate and maintain building

 Evaluates the building’s environmental quality

5

Cost Savings

Studies have shown:

 Costs of RCx activities: $0.13 to $2.00 per sq. ft.  Payback: 3 months to 2 years  Overall energy savings can reach approximately 15%

Utilities without DSM Programs

Enmax and Epcor  No apparent programs available based on searches online Yellowknife and NWT  No apparent programs available based on searches online  Artic Energy Alliance offers support and incentives

11

Utilities without Specific RCx Programs

Newfoundland  Assessment (100%), Audit (50%), Study (75%), Proposal, Project, M&V. $0.10/kWh (max $50,000) Prince Edward Island  Financial incentives towards retrofitting existing buildings New Brunswick  Financial incentives towards determining the potential for energy efficiency upgrades as well as towards project costs for commercial buildings

12

Utilities without Specific RCx Programs

Saskatchewan  Customized support and incentives to help industrial facilities identify energy waste and reduce the cost associated with electrical energy use during the production process  Commercial programs for lighting, ice rinks, parking lots, Performance Contracting

Yukon

 New initiative, inCharge, launched Oct. 1st 2014 - Current initiatives include LED lighting rebate, distribution of low-cost energy efficient products and public education/engagement

Utilities with RCx: Nova Scotia

Existing Building Commissioning

 Choose a requisite service provider to perform an on-site walkthrough and determine energy-saving opportunities (max $2500)  If adequate opportunities to save electricity are identified, the service provider begins the investigation and implementation stages  A report is produced in order to choose which measures should be implemented  Efficiency Nova Scotia can cover up to 75% of the work (max. $25,000/building)

Buildings Program – Catered Component

 Tailored financial assistance and technical support for new and existing commercial or institutional buildings  Area of at least 5,000 m2 and generating at least 25,000 kWh/year of eligible annual electricity savings  RCx is not recognized as an EE measure for the program  Pilot program a few years ago but no program currently available

Recommissioning Program (Pilot Project)

 Up to $54,000 in incentives  accredited recommissioning (RCx) agent by the Ministère des Ressources naturelles  Five Phases  Planning and applications  Investigation (50% funding, between $10k and $25k based

• n consumption)

 Implementation and hand off (50% funding, max $25k based on $0.25/m3 ($6.50/GJ)variable incentive)  Continuous monitoring (100% funding, max $4k)

Existing Building Commissioning Program

 Program for owners or lessees of Chilled Water Systems  Four Stages of Participation 1. Scoping Study Phase (Up to $2,500 to hire industry expert) 2. Investigation Phase (Up to $30,000 to analyze systems) 3. Implementation Phase (Up to $5,000 for upgrades) 4. Hand-Off/Completion Phase (Up to $2,500 for final reporting) Note: Energy Audit Program  Can mesh with the RCx offer to broaden the scope
