Baseline of Architectural Windows
Baseline information of architectural windows and glazing is necessary for any energy modeling and simulation when it comes to design optimization and performance comparisons. Such information basically includes U-factor, SHGC, and visible transmittance, which are not independently determined because of the limits of the current windows and glazing materials and related technologies.

Intrinsic relationship between Tv and SHGC
Through randomly searching and downloading window products, we formed a large database that covers nearly 8,000 different manufacturer product lines and more than 550,000 National Fenestration Rating Council-certified fenestration products.
