Industrial air conditioner

Improve your chilled water system's energy performance

Air conditioning can be costly to operate and maintain, particularly if you have a large chilled water system. Now there are options for immediately reducing your electricity bills and, over time, lowering maintenance and replacement costs.

With the Existing Building Commissioning program for chilled water systems, funding is available for:

  • Hiring an expert to analyze the chilled water system and make recommendations for increasing its energy efficiency
  • Buying and installing metering equipment
  • Implementing the recommended upgrades

Is your building eligible?

The Existing Building Commissioning program is for owners or lessees of chilled water systems located in:

  • Commercial buildings such as offices, retail and grocery stores, restaurants, hotels and warehouses
  • Institutional buildings, including hospitals, universities, municipal halls and arenas
  • Multi-family buildings, such as apartments (including low-income or social housing) or condominiums

You'll also need a general service account greater than 50kW or a Large User Account with your local electric utility. And if you lease, you'll need the owner's consent or authorization to move forward.

Is your chilled water system eligible?

To be eligible for the Existing Building Commissioning program, the chilled water system must:

  • Be more than three years old
  • Cool an area greater than 50,000 square feet
  • Not be scheduled for replacement within the next two years
  • Not have been refurbished or retrofitted for the past three years

Chilled water systems may be eligible for the program, provided they have not previously been included in this program or the Independent Electricity System Operator's (IESO) Chilled Water Plant Ongoing Commissioning Pilot. They also must not have received incentives through any other IESO-funded programs in relation to the chilled water system.

How Does the Existing Building Commissioning program work?

There are four stages of participation:

1. Scoping Study Phase

A qualified Commissioning Agent – or industry expert – is hired to create Scoping Study Commissioning Report. This report provides a snapshot of your chilled water system and its performance. The Commissioning Agent is hired on a contractual basis only - and is not an employee.

The Commissioning Agent you choose must have either:

  • A commissioning certificate from the Association of Energy Engineers, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, or the Building Commissioning Association, or
  • Experience as a project manager of a Chilled Water System commissioning project to meet either LEED or Canadian Standards Association Z318 (Commissioning of Health Care Facilities) standards, or under the OPA's Chilled Water Plant Ongoing Commissioning Pilot. Please note that the agent must provide two letters of reference to the owner or lessee of the chilled water system.

The Scoping Study Commissioning Report will:

  • Describe your chilled water system in full. The estimated cooling loads, electricity consumption and operating hours will also be noted
  • Propose and detail several energy-efficiency measures for saving electricity while operating your chilled water system
  • Show the estimated electricity consumption and demand savings that each measure would produce in the first year
  • Identify the existing metering points and additional metering required for the Investigation Phase as well as include the plan for measuring the actual electricity consumption and demand savings anticipated in the next Commissioning Phase

2. Investigation Phase

A Data Acquisition System is installed and/or enhanced with metering points to log data from the Chilled Water System. The Commissioning Agent analyzes the results and produces an investigation Phase Commissioning Report. Recommended energy-efficiency measures for reducing electricity consumption and peak demand of the Chilled Water System are included as is a project Measurement & Verification Plan.

3. Implementation Phase

On completion of the Investigation Phase, the participant commits to implement all measures with a payback period of less than two years. Measures with a payback period of greater than two years may be eligible for further incentives on implementation. The Commissioning Agent monitors and analyzes the results, which form the basis of the Agent's Implementation Phase Commissioning Report.

4. Hand-off/Completion Phase

A Hand-Off/Completion Phase Commissioning Report is produced by the Commissioning Agent. It describes the training and documentation provided to the Chilled Water System operators as well as an analysis of the yearly energy consumption and savings for your chilled water system.

Attractive and easy to earn - consider the Incentives now available

Each of the four Commissioning Phases offers an incentive.

Scoping Study Phase Incentive

  • The lesser of:
    • The amount actually owing and paid to the Commissioning Agent for preparing the Scoping Study Report, excluding applicable taxes, or
    • $2,500 less any other financial incentives provided by the province of Ontario

Investigation Phase Incentive

  • Calculated at:
    • $18 per ton of chilled water system cooling, up to a maximum of 75 per cent of the amount actually owing and paid to the Commissioning Agent for preparing the Investigation Phase Commissioning Report, excluding applicable taxes, plus
    • $6 per ton of chilled water system cooling, up to a maximum of 75 per cent of the eligible costs of acquiring and installing the Data Acquisition System up to a maximum of $30,000, less any other financial incentives provided by the province of Ontario

Implementation Phase Incentive

  • The lesser of:
    • The amount actually owing and paid to the Commissioning Agent for preparing the Implementation Phase Commissioning Report, excluding applicable taxes, and
    • $5,000 less any other financial incentives provided by the province of Ontario
  • Plus for major measures with a project pay back of more than two years, the lesser of:
    • The greater of Implementation Phase Energy Savings x $0.10/kWh and Implementation Phase Demand Savings x $800/kW
    • 50% of the eligible costs of purchasing and installing the major measures, excluding applicable taxes, and
    • The amount calculated for X where X = A (eligible costs for major measures) – B (any other financial incentives provided by the province of Ontario) – 2C (reductions in annualized energy, operating and maintenance costs)

Hand-off/Completion Phase Incentive

  • The lesser of:
    • The amount actually owing and paid to the Commissioning Agent for preparing the Hand-off/Completion Phase Commissioning Report, excluding applicable taxes, and
    • $2,500 less any other financial incentives provided by the province of Ontario.

Which costs are eligible?

Eligible costs for the Data Acquisition System in the Investigation Phase and any equipment required for the Implementation Phase are reasonable costs payable by you to an arm's length third-party, including the costs of :

  • Equipment, including shipping, delivery and duties
  • Labour for installation
  • Disposing, decommissioning or recycling any residual material
  • Inspections required by law and regulations
