 · Building façades must endure severe climatic exposure throughout their lifetimes. To prevent damage and expensive repairs, ageing tests are used in durability assessments. The NT Build 495 describes an artificial ageing procedure to address building material and component resistance to ultraviolet (UV) light, heat, water, and frost using a climate simulator. The test has been used for ...

 · In Ref, the first exterior solar window facade was installed. A total surface area of 300 m 2 was installed with 1400 DSC modules, each 35 × 50 cm 2, and with 5 different shades of red, green and orange, giving the ensemble a warm and dynamic aspect. DSCs not only produce electrical energy from solar energy, but they also shade the building ...

Passive solar building design

Passive solar technologies use sunlight without active mechanical systems (as contrasted to active solar, which uses thermal collectors).Such technologies convert sunlight into usable heat (in water, air, and thermal mass), cause air-movement for ventilating, or future use, with little use of other energy sources.A common example is a solarium on the equator-side of a building.

Window Systems1

Solar Heat Gain Coefficient (SHGC) SHGC measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted, and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient,

Glazing | YourHome

Solar heat gain. The solar heat gain coefficient (SHGC) for windows (expressed as SHGCw) measures how readily heat from direct sunlight flows through a whole window (glass and frame together). SHGC is expressed as a number between 0 and 1. The lower a window's SHGC, the less solar heat it transmits to the house interior.

Window

A window is an opening in a wall, door, roof, or vehicle that allows the passage of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or ...

Solar Heat Gain Calculation

The NFRC (National Fenestration Council) describes Solar Heat Gain Coefficient (SHGC) as: Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat from the sun. SHGC is expressed as a number between 0 and 1. The lower the SHGC, the better a product is at blocking unwanted heat gain. Blocking solar heat gain is particularly ...
