Optimizing Energy Performance: RCx Programs Across Canada Prepared - PowerPoint PPT Presentation

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 organizational aspects of Energy Management We design and implement cost effective approaches to address comfort, efficiency and reliability. 2 2

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

RCx Goals Specifics of retrocommissioning:  Optimizes energy efficient design features  Addresses equipment performance and system integration issues  Ensures building staff can effectively operate 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% 6

Prism’s Experience - Top 10 Retro-commissioning Opportunities 1 Reduce Equipment Runtime 2 Optimize Economizer Operation 3 Eliminate Simultaneous Heating and Cooling 4 Optimize Supply Air Temperature 5 Optimize Zone Temperature Setpoints 6 Eliminate Unnecessary Lighting Hours 7 Optimize Ventilation Rates 8 Volume Control for Pumps and Fans 9 Add / Improve Chilled Water Temperature Reset 10 Eliminate Passing (leaky) Valves 7

RCx Energy Conservation Initiatives 8

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 10

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. 1 st 2014 - Current initiatives include LED lighting rebate, distribution of low-cost energy efficient products and public education/engagement 13

Utilities with RCx: Nova Scotia 14 Website link: http://www.efficiencyns.ca/energy-solutions/existing-building-commissioning/

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) 15

Utilities with RCx: Québec 16 Website link: http://www.hydroquebec.com/business/energy-efficiency/programs/buildings-program/

Utilities with RCx: Québec Buildings Program – Catered Component  Tailored financial assistance and technical support for new and existing commercial or institutional buildings  Area of at least 5,000 m 2 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 17

Utilities with RCx: Québec 18

Utilities with RCx: Québec 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 on consumption)  Implementation and hand off (50% funding, max $25k based on $0.25/m3 ($6.50/GJ)variable incentive) 19  Continuous monitoring (100% funding, max $4k)

Utilities with RCx: Ontario 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 21
