Commercial Windows Attachment (SGS) Initiative
Project info
Solarc teamed with the Northwest Energy Efficiency Alliance (NEEA) and Navigant Consulting, Inc. to research window attachments, which includes products installed in commercial and residential markets. This study focused on secondary glazing systems (SGS), which are commercial single-pane window retrofits installed on the interior side of a building. The study’s goal was to conduct initial market research to confirm product performance, barriers, and market information sufficient to inform a preliminary market baseline. Solarc's role was to provide analysis with the use of prototypical commercial buildings in various regions in North America. Solarc was tasked with economic analysis services for secondary glazing systems and the development of an Excel-based simplified savings calculator based on Energy Plus modeling results.
