Instead of a west-facing window, designers use an R-13 foam-filled solid energy-efficient exterior door. It may have a glass storm door on the outside so that light can pass through when the inner door is opened. East/west glass doors and windows should be fully shaded top-to-bottom or a spectrally selective coating can be used to reduce solar ...
Glass brick has an r value between 1.75 and 1.96, close to that of thermopane windows. [ 1 ] [ 2 ] There are newer glass blocks injected with argon gas and having a layer of low-emissivity glass between the halves, which increases the insulative (U) value to 1.5 W/m 2 ·K, which is between triple glazed windows (1.8 W/m 2 ·K) and specialty ...
The Tucson High School Galleria and reflexive library (pictured) feature a modern atrium tetrastylum with four support columns and open roof. In architecture, an atrium (pl.: atria or atriums) [1] is a large open-air or skylight-covered space surrounded by a building. [2]
In architecture, a lightwell, [NB 1] sky-well, [NB 2] or air shaft is an unroofed or roofed external space provided within the volume of a large building to allow light and air to reach what would otherwise be a dark or unventilated area.
A fixed skylight consists of a structural perimeter frame supporting glazing infill (the light-transmitting portion, which is made primarily of glass or plastic). A fixed skylight is non-operable, meaning there is no ventilation. Operable skylight. An operable (venting) unit skylight uses a hinged sash attached to and supported by the frame.
Shading coefficient (SC) is a measure of thermal performance of a glass unit (panel or window) in a building. It is the ratio of solar gain (due to direct sunlight) passing through a glass unit to the solar energy which passes through 3mm Clear Float Glass. [ 1 ]
