Fenestration Software Tools

Lead Performer: Lawrence Berkeley National Laboratory - Berkeley, CA
-- Window Covering Manufacturing Association/Attachments Energy Ratings Council - New York, NY
DOE Funding: $1,062,000
Cost Share: Provided by LBNL

Project Term: 10/1/2013 - 9/30/2018

Project Objective

Manufacturers have been using Lawrence Berkeley National Laboratory’s (LBNL’s) fenestration software tools for decades to design energy-efficient window technologies. These advanced, independently verified tools are moving the window industry toward virtual, rapid product design and product development, which accelerates design-to-market delivery. In fiscal year (FY) 2014, the primary effort is to maintain and support software tool use through bug fixes, user support, and user manual updates. The goal for the end of FY 2014 is to release a new version of software tools (v7.3) with improved reliability and robustness, updated knowledge base articles, frequently asked questions, and additional tutorials addressing issues that are most frequently raised by users.

Project Impact

LBNL's estimates their fenestration software tools have the technical potential for energy savings by 2030 from windows is 2 quads (commercial and residential) and an additional 0.17 quad for daylighting. This project also helps accomplish carbon emission reduction goals through the free access to these world class modeling tools.
