Emerging Gas Opportunities in Commercial Space
Heating

• Kara Rodgers, CEE

2
Commercial Boiler Exploration

• Heat over 30 of commercial floor space
• Primarily a replacement market, but demand is
  steady
• 85 of boilers are fueled by natural gas
• Theres an opportunity for gas savings in this
  replacement market

3
Commercial Boiler Exploration

• Working to update a 2001 market study
• Market for condensing boilers has grown
  considerably
• Installation and system design are important for
  achieving savings
• Conflicting efficiency measures may make common
  efficiency specifications difficult

4
Commercial Boiler ExplorationNext Steps for 2008

• Define the scope of a boiler system including
  auxiliaries
• Develop a methodology for evaluating system
  replacement versus optimization
• Engage Manufacturers
• Develop a Performance Specification

5
Gas Pack Rooftop Unit Exploration

• Heat nearly half of all commercial floor space in
  the U.S.
• Members are seeing a growing load from this end
  use
• Measures of efficiency need improvement
• Other technical hurdles exist

6
Still More Opportunities for Gas Efficiency in
Commercial Buildings

• Exploring the opportunities for gas savings in
  energy management systems
• Investigating heat-recovery technologies
• Coordinating with Commercial Whole Buildings
  Committee

Next Steps for CEEs High-Efficiency Water Heater
Initiative
8
High-Efficiency Residential Gas Water Heating
Initiative
9
Initiative Participation Requirements

• Incorporate the CEE efficiency specifications for
  water heaters in an incentive-based program at
  Tier 0, Tier 1, or Tier 2 and
• Undertake the awareness-building aspects of the
  initiative, making use of communication messages
  developed by CEE committee

10
Influencing Behaviors are Key

• Influence Distribution Channel
• Distributors to stock high-efficiency models
• Installers to understand and promote
  high-efficiency models
• Influencing Consumers
• To understand the benefits of efficiency
• To request high-efficiency models
• To replace their water heaters early

11
At the 2007 Industry Partners Meeting
Manufacturers Requested

• Simplified and Standardized Rebate Application
  Process
• Improved Program Summaries
• National Water Heating Marketing Plan

Tankless Water Heater Field Test Protocol

• Questions remain about the delivered in-field
  performance of tankless water heaters
• CEE has created a protocol for testing the
  delivered efficiency of tankless water heaters
  and the behavioral changes they may cause
• The protocol is ready for pilot tests by members
