glass color in historic buildings
Posted: 19 Oct 2007 09:45 AM |
Where can I find information about glass color and daytime reflections?
Our City has a downtown historic district. When property owners are replacing windows, they cannot change the appearance of the glazing, yet of course we all want to decrease energy use. Are there coatings that do not change the perceived color of the glazing and give a traditional reflection?
Double glazing is permitted, but it does have a different "look" due to having four surfaces. Are there coatings that are energy efficient that could also cut down on this effect?

Good Morning and thank you for your recent post on the NFRC Discussion Board. We will have a reply post to you within the next few days (early next week).
I appreciate your patience and your interest in the NFRC: the nations resource for fair, accurate, and reliable energy performance ratings for windows, doors and skylights. |

Dear Sir/Madam,
NFRC rates window energy performance only. NFRC ratings do not report color or visible reflection.
NFRC ratings do include U-factor (winter heat transmission value) and SHGC (solar heat gain coefficient, summer heat gain potential). These ratings will answer part of your question. NFRC recommends using window that meet the ENERGY STAR requiremnts for your location. please click on www.energystar.gov to select energy efficient windows.
Thank you for your interest. if you have futher questions, please email, me, Ray McGowan (rmcgowan@nfrc.org)
