Commercial 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 Real Estate Infrastructure Market Progress Evaluation Report #1
    Through its Commercial Real Estate infrastructure program, Northwest Energy Efficiency Alliance (NEEA) is working to support Northwest utilities’ efforts to improve energy efficient operation of commercial buildings in their service territories. To accomplish this, NEEA made accessible a set of best practices, tools and resources which utilities, Bonneville Power Administration and Energy Trust of Oregon can tap into in order to affect improved commercial building operations. In this report, the research team (Navigant and subcontractor Cadeo) conducted a characterization of the market, assessed the NEEA-developed Spark tool – a web-based tool designed to assess the potential value of efficiency project in buildings, and reviewed the effectiveness of retrofit efforts in demonstration projects. Findings from this research include: awareness of energy efficiency as a source of economic value exists within the commercial marketplace, however practice lags awareness; the Spark tool proved useful in general, but will require some fine-tuning; initial assessment of demonstration sites realized economic benefits from energy efficiency renewal efforts.

  • Market Progress Evaluation Report 1 Energy Codes Program
    Northwest Energy Efficiency Alliance (NEEA) directs an energy codes program, the objective of which is to get sustained market change through the development, adoption, and implementation of increasingly stringent code in residential and commercial construction resulting in energy savings. This Market Progress Evaluation Report (MPER) report presents the findings of a formal evaluation of this program’s progress in achieving its goals and provides recommendations to improve program performance moving forward. The focus of this MPER was on codes efforts undertaken since 2011 in the northwest region (in the states of Washington, Oregon, Idaho and Montana). Key research objectives of the MPER were to conduct reviews of: the program logic model; cost effectiveness assumptions used to estimate program influence; program progress achieved; and effectiveness of processes implemented. The evaluation found that NEEA’s codes program has made a significant contribution to the Northwest region through its support of energy code development and adoption, implementation and compliance. The report’s recommends NEEA put additional focus on the timing and targeting of training.

  • Commissioning Long-Term Monitoring and Tracking—2015 Square-Footage Update (2016 Study)
    From 1998 to 2004, the Northwest Energy Efficiency Alliance (NEEA) managed an initiative to transform the building commissioning market in the Northwest. The initiative aimed to make commissioning standard practice in public buildings and to create a standardized professional certification body for commissioning providers. To assess the outcomes of the initiative, NEEA began long-term monitoring and tracking of the commissioning market in 2005. The 2016 study finds that the population of certified commissioning providers and firms offering commissioning services is growing. In 2015, there were 75 firms performing commissioning in the Northwest. These 75 firms carried out more than 26 million square feet of new building commissioning and nearly 37 million square feet of existing building commissioning in the region. Market penetration of new building commissioning across the region was 49 percent. As in previous years, market penetration for all types of commissioning was higher in Oregon and Washington than in Idaho and Montana. As part of this year’s study, evaluators estimated the baseline market share of commissioned floor space and found that in 2015, 52 percent of new building commissioned space and 62 percent of existing building commissioned space would have occurred without NEEA intervention. The study recommends future research to improve market size estimates, increase survey response rate, and to better track the population of commissioning providers.
