Window Attachments

Creating a window into future savings

This new program encourages the installation of high-performance commercial window attachments (secondary glazing systems) as a standard practice for competitive advantage in Northwest buildings.

Designed for use in existing commercial office, historic, educational, and government buildings with low-performance windows, window attachments are approximately half the cost of replacement and may be installed as a stand-alone energy efficiency measure or as part of a deeper energy retrofit.

The program will work to identify which building types are most cost-effective for window attachments, raise awareness of the product in the market, and partner with the Attachments Energy Rating Council (AERC), in coordination leading commercial window manufacturers, to influence national standards. 

  • Commercial Window Attachments, Phase 1 Research
    This preliminary market research focused on understanding the market barriers and any product performance concerns with Secondary Glazing Systems (SGS), an interior window attachment that improves the performance of existing windows in commercial buildings. The bulk of the research occurred between March and October 2017 and included a literature review, a review of existing market research, and primary data collection with representatives from projects installed throughout the United States. The limited number of in-region installations and lack of access to building contacts indicate that the Northwest Energy Efficiency Alliance (NEEA) will need to continue to collect region-specific intelligence on these products. The findings indicate that NEEA staff should consider attending trade shows or other networking events attended by glazing contractors and design teams responsible for interior rehabilitation (as opposed to new construction) to improve awareness of the product among Northwest professionals. Product "mock ups" are another common way to expose potential users to the product. The research found no industry wide concerns with the product performance nor any evidence of unexpected product failure. Additional research needs include supply chain research specific to the Northwest.

  • 2016 BOC Program Data Analysis
    This memorandum documents Research Into Action’s analysis of the Northwest Energy Efficiency Council Building Operator Certification (BOC) program dataset as of 2016. A review of the BOC dataset of certified operators took place during January and February 2017. This report provides an updated count of the number of active certified building operators for 2016 energy savings reporting. In 2016, the BOC program registered 157 new certificates. Also in this report, the reader will find a brief update on the program’s recent alignment with the ISO 17024 standard, the process used to determine the number of active BOC certificants, and a year-by-year count of new, retired, and total active certificants. An additional section has been included this year on opportunities for further research.
