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. 

  • Market Progress Evaluation Report 1 Energy Codes Program
    Northwest Energy Efficiency Alliance (NEEA) directs an energy codes program, the objective of which is to influence a sustained market change through the development, adoption, and implementation of increasingly stringent energy codes in residential and commercial construction. This report presents the findings of a formal evaluation of this program. The evaluation framework used in this study is called a Market Progress Evaluation Report (MPER). This MPER was designed to evaluate the program’s progress in achieving its goals and provide recommendations to improve program performance moving forward. The focus of this MPER was on codes efforts undertaken since 2011 in NEEA’s 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 recommendations for improvement include improved training assessment and timing.

  • 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.

  • Building Operator Certificate Program Dataset Analysis
    This memo documents the analysis of the Northwest Energy Efficiency Council Building Operator Certification (BOC) program dataset as of 2015. The goal of this effort, conducted each year as part of the BOC evaluation, is to describe the 2015 new BOC certificants and update the count of active BOC certificants in the Northwest region (Idaho, Montana, Oregon, and Washington). Active certificants are those individuals who have received or renewed the BOC credential since 2010 and are the individuals for whom the Northwest Energy Efficiency Alliance counts energy savings for 2015. The results of the analysis find 228 new 2015 certifications and 115 certificants whose savings retired in 2015. In all, BOC has certified 2,796 individuals, of whom 1,568 are currently active.
