Window Ratings - Energy Ratings. In order to apply the ENERGY STAR ® label to products, manufacturers must first test their FENESTRATION products according to NFRC procedures, which include independent testing at NFRC approved laboratories.
These tested products bear NFRC labels that provide important information on the Energy Ratings for the products. This information is of little benefit to you IF you are unsure how to interpret the results and are unaware of the needs for your home. The NFRC label provides ratings for U-factor and Solar Heat Gain Coefficient, and Visible Transmittance (required ratings), and may include information on testing for Air Leakage and Condensation Resistance. U-factor measures how well a product prevents heat from escaping a home or building. U-factor ratings generally fall between 0.15 and 1.20. Glass Transmittance. Glass Transmittance Transmittance refers to the percentage of radiation that can pass through glazing.
Transmittance can be defined for different types of light or energy, e.g., visible transmittance, UV transmittance, or total solar energy transmittance. Understand Window Energy Ratings: U-Value, Lo-E Glass, & SHGC. Two or more individual panes of glass separated by a specified spacer bar system and then sealed to be air and water tight.
The "captured" airspace between the panes of glass forms the insulating barrier. The majority of modern energy efficient window systems utilize some type of insulated glass (IG) application. Emissivity is the capability of a surface to emit heat radiation. A black surface is often used as a constant in measuring other surfaces against it. For example, in measuring the emissivity of a particular IG unit, the IG unit is placed next to a solid black surface and subjected to an identical heat source. With relation to energy efficient window systems, lower emissivities are desired. U-Value is the measure of a window's ability to reduce heat loss during indirect radiation exposure; such as during the winter months in moderating climates.

Components. Low emissivity. Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy.
All materials absorb, reflect and emit radiant energy, but here, the primary concern is a special wavelength interval of radiant energy, namely thermal radiation of materials with temperatures approximately between 40 to 60 degrees Celsius. Definition[edit] What is the type of glass the Steven Holl used on the Nelson-Atkins Museum?
The Nelson-Atkins Museum of Art, Kansas/USA. Bendheim Wall Systems Project Gallery. United Kingdom and Ireland. Structural Glass Systems. Translucent Skin Detailing. Glassworks- UNSW Interior Architecture Grad Project on Behance. Glassworks is a publicly accessible glass art centre with workshop space, a gallery, and café.
It is located at 34-40 Burton St, Darlinghurst, to serve the East Sydney community. It sits amongst other art galleries and aims to revitalise the area. The purpose of the centre is to provide infrastructure and access to facilities for glass artists and students for the production of high quality and innovative glass art.

For me, it would be an Ocean View. Great if it’s a Northern or Eastern view because you don’t generally have to deal with the hot afternoon setting sun, but if the view is towards the South or West, that’s a different story. South and West views give you lovely sunsets but very hot afternoons. You may be living in a glass oven by the end of the day. Not only does the sun heat up the room, it also fades furniture, flooring and can destroy your interior plants. Reflections on glass. Use of glass in construction has become a fad.
But it is not the right choice for Indian climate CBI building in Lodhi Road area, New Delhi (Photo: Meeta Ahlawat) There was commotion at the CBI headquarters in Delhi on the day the Northern Grid tripped in July. Though diesel gensets sprung into action, the building occupants were visibly uncomfortable as the central air-conditioning chillers had no power back-up. RG Solid Glass Wall Doors: Technics - Bene Office Furniture. Very High Performance Windows can be More Energy Efficient than many insulated walls.
