Secondary: Mark Rehley
Funding: Scoping and project design funded, Implementation funding will begin in Q1 2021
Product Components
Secondary Windows
Project Objectives:

Assess the energy savings and product performance as well as occupant acceptance of  suspended film and rigid plastic panes in secondary windows.

Current Project Phase: Active
Current Project Status: Scoping and research design completed by PNNL to test in-place, on an occupied building with a test office and control office, using suspended films, rigid plastic, and potentially the hard-coat, washable Low-e Surface Applied Films. Testing will evaluate technical, qualitative, and product “fit for use” performance including visual, sound and comfort impacts. The testing will occur for summer and winter periods through seasonal changes and temperature extremes. In discussion on selected sites.
Project Outcome: Not Specified
Notes on Project Outcome: N/A
