Fluorescent Pigments for High-Performance Cool Roofing and Facades

Lead Performer: PPG Industries - Pittsburgh, PA
Partner: Lawrence Berkeley National Laboratory - Berkeley, CA
DOE Funding: $474,000
Cost Share: $56,000
Project Term: 10/1/2013 - 9/30/2014
Funding Opportunity Announcement: Building Technologies Innovations Program 2013 (DE-FOA-0000823)

Project Objective

This project is developing dark-colored, cool pigments that combine near-infrared (NIR) fluorescence with NIR reflectance. These pigments will obtain unprecedented effective solar reflectance (ESR) values for dark-colored coatings used in the building envelope. Metal coatings will be formulated and characterized in dark red and near-black colors with ESR values of 0.50–0.70, a significant improvement over standard dark coatings, which have ESRs of only about 0.10–0.30. If successful this project would yield a product that Such coatings would satisfyreduces buildings’ cooling load while satisfying consumer demand for dark colors on building surfaces.

Project Impact

PPG Industries estimates this project will save 0.17 quads annually, worth approximately $1.3 billion per year.
