Commercial

Gas Boiler Systems Initiative


Overview

Commercial boiler systems are technically complex in terms of both equipment and installation. Understanding the relationship between system design and various energy solutions is important to help maximize energy savings over time. This Initiative addresses energy savings opportunities with these objectives:

  1. increase the number of new commercial boiler systems operating in the condensing range
  2. increase the number of existing commercial boiler systems that are optimized to operate at the highest efficiencies allowable for the given system throughout the year
  3. increase the number of quality installed and maintained high efficiency commercial boiler systems
  4. educate building owners, design engineers, and contractors on what constitutes high efficiency in a given system and options for maintaining high efficiencies throughout the life of the boiler
  5. educate contractors on the importance of, and optimal steps for, conducting quality installations and maintenance for high efficiency commercial boiler systems
  6. encourage creation of an enhanced efficiency metric for commercial boiler systems. This will replace the current steady state boiler metrics and provide better infield operating efficiency of the boiler system throughout the year

This Initiative focuses on a systemic approach to savings, recognizing the role each component plays in overall efficiency. Commercial Boiler Equipment and Functionality  Specifications define cost-effective efficiency levels for boilers and related requirements for optimizing boiler performance regardless of the system design. The new Minimum Piping Insulation Thickness Specification reflects ASHRAE standards.

To ensure a whole systems focus, the Initiative also covers requirements for multiple boiler systems, including hybrid systems, retrofit controls and equipment for conventional boilers, and quality installation, maintenance, and operation. For all elements, the Initiative requires contractor compliance with manufacturer instructions and all federal and local standards for boiler system installation, operations, and maintenance safety.


Accomplishments

We appreciate the opportunity to provide comments on the CEE Commercial Boiler Systems Initiative, and found it thoughtfully put together. I hope that all designers read and apply the principles you describe.Jeff Kleiss, Lochinvar, LLC
The revised CEE Commercial Boiler Systems Initiative will clarify program needs for the industry and maintain Initiative relevance in the face of an innovative industry that is moving away from simple product efficiency and toward evaluating and promoting comprehensive systemic energy saving solutions.

CEE submitted a comment letter to US EPA regarding membership positions on Commercial Boiler specifications and system considerations.


Analysis of the distribution chain suggests points at which member messaging may be most effective.

How to Participate

As with all CEE Initiatives, participation in the Commercial Boiler Systems Initiative is voluntary. To be considered an Initiative participant, a program must meet a minimum set of requirements. For this Initiative, these requirements emphasize the need for programs to go beyond incentivizing the boiler alone by providing a comprehensive strategy for capturing savings through system optimization.

Participant requirements are as follows:

  • Offer an educational or incentive program that incorporates:
    • CEE Equipment and Functionality Specifications.
    • Minimum Piping Insulation Thickness Requirements.
    • Hybrid Boiler System and Fully Condensing Multiple Boiler System Requirements.
    • Quality Installation, Operations, and Maintenance Requirements.
    • Retrofit control and equipment options for existing conventional boilers.
  • Undertake awareness and system optimization measures related to quality installation and quality operations and maintenance.
  • Conduct outreach to key market players within the distribution channel, including facility managers.
