Complex Product VT Rating Bid Review
Task Group
CHAIRS
CONTACT INFORMATION
Project Objective
Develop a methodology
for determining Visible Transmittance (VT) for products with complex
glazings. The project will seek to analyze a range of complex
products using both integrating sphere testing and ray-tracing
simulation and compare the methodologies. This project will research,
develop, construct and validate a test methodology to determine
the VT of complex products. This methodology will be evaluated
against current techniques as well as ray-tracing simulation techniques
to determine the appropriate ratings procedures for complex products.
Source spectrum will be monitored throughout research project
and reported.
Status
- July 29, 2009-Solatube has completed its testing, Velux has
partially completed testing, and LBNL will begin testing immediately
- March 09-This project is now an interlaboratory comparison
among Velux, Solatube, and LBNL. This PMTG will still
follow the progress like a research product.
- The PMTG will reconsider the entire contract and may develop
a new RFP for rating development or consider a new path to achieve
the desired rating (see December 17 notes below)
- ATI awared contract in summer 2007. work not to begin
until optical expert approved by this PMTG.
