Energy Codes

Increasing progressive effectiveness of energy codes

The NEEA Codes and Standards program supports regional stakeholders in the development and adoption, training and implementation of energy codes. 

States engage in the code development process along different cycles and code versions, but all states now use the International Energy Conservation Code (IECC) as a baseline for their commercial energy codes. All states except Oregon now use the IECC as the basis of their residential code. 

The adoption of codes is the responsibility of state code boards or agencies. Official state-by-state  energy code information can be found on state building code websites:  

Idaho -

Oregon -

Washington -

Current Northwest State Codes

Each state has building code boards that make final code adoption decisions. NEEA provides funding for code development, technical assistance, and education support within each state:

  • NEEA: Commercial Lighting Decision Maker Groups
    Northwest Energy Efficiency Alliance (NEEA) contracted with Seek, Inc. to run three focus groups of commercial lighting purchase decision makers. The research sought to understand more about the decision making process involved in undertaking a major lighting upgrade, to learn about the resources used to decide on a product and to develop segmenting profiles with targeted messages that will resonate with the decision makers. Each group represented a different decision maker or influencer: building owners, property managers, and lighting designers and architects. The final report summarizes the key takeaways, develops profiles and provides messaging recommendations for each group based on the research.

  • Luminaire Level Lighting Controls (LLLC) Market Characterization and Baseline Report
    In early 2014, the Northwest Energy Efficiency Alliance (NEEA) began developing its Luminaire Level Lighting Control (LLLC) Initiative for office buildings and warehouses. LLLC systems have a sensor in each light fixture that senses occupancy, determines optimal light output, and in some system models, reports out energy use and other data. In addition to reducing energy use, LLLCs offer non-energy benefits such as improved worker productivity and health. In 2015, NEEA contracted with Research Into Action and its subcontractor, Energy 350, to uncover market barriers to LLLC adoption, and recommendations to overcome them. Recommendations: 1) Train installers 2) Include LLLCs in commercial energy codes 3) Engage with lighting designers on specifying LLLCs 4) Leverage other NEEA initiatives’ distribution channels 5) Explore the concept of “lighting as service” as a way to deliver LLLCs to the market The study also found that current commercial market penetration of LLLC systems is 0.5 percent in offices (large, medium and small) and 0.8 percent in warehouses. The study projected that between 2016 and 2035, market penetration will increase to 50 percent in new construction and major renovations, and to 18 percent in retrofit regional stock.

  • Dimming Systems Characteristics
    Northwest Energy Efficiency Alliance commissioned a study to delineate the characteristics of 18 dimming systems as part of its Luminaire Level Lighting Control initiative. In theory, adjusting the light level by dimming 15 percent at the control station will have that intended effect (light level or power consumption reduction) at the light source or driver. In practice, this rarely happens. The study found that each ballast’s response to a linear control signal input varied and was not linear. The variances ranged from minor (plus/minus 2 percent) to significant (plus/minus 18 percent). This has implications for utilities in forecasting the anticipated energy savings of a lighting control system.
