Intercepting sunlight before it reaches the walls and glazing of a building dramatically reduces the amount of heat entering that building. External shading devices can reduce solar heat gain through glazing by up to 80%. By designing shading devices according to the suns seasonal path, both summer shading and winter solar gain can be achieved in climates with seasonal variations ...
There are many different reasons to want to control the amount of sunlight that is admitted into a building. In warm, sunny climates excess solar gain may result in high cooling energy consumption; in cold and temperate climates winter sun entering south-facing windows can positively contribute to passive solar heating; and in nearly all climates c... See full list on wbdg.org The use of sun control and shading devices is an important aspect of many energy-efficient building design strategies. In particular, buildings that employ passive solar heating or daylightingoften depend on well-designed sun control and shading devices. During cooling seasons, external window shading is an excellent way to prevent unwanted solar h... See full list on wbdg.org Among the primary types of buildings that can benefit from the application of shading devices are: 1. Barracks and other multi-family housing projects, especially in temperate or warm climates; 2. Offices, administration buildings, and other structures employing daylighting; and, 3. Nearly any structure in warm, sunny climates. See full list on wbdg.org See full list on wbdg.org Publications 1. Low-E Glazing Design Guideby Johnson, Timothy E.

See full list on wbdg.org External shading devices are desirable in hot climates for the control of solar heat gains in buildings by intercepting unwanted solar rays especially during the overheated periods thus substantially reducing the cooling load resulting to huge energy savings. Broadening our expertise in internal roller shades to the building exterior, Hunter Douglas Architectural's motorized external roller shades provide excellent control of glare and thermal gain. Our high-performance exterior fabrics remain colorfast, resist damage from water and heat, remain dimensionally stable, and are resistant to rot. A well-designed solar shading system incorporates semi-transparent PV glass for effective shading and opaque glass to maximize energy production and maintain visual consistency. Explore how our solar shading solutions can elevate your building's performance and environmental impact. External shading devices on a building faade is an important passive design strategy as they reduce solar radiation. Although studies have proven the benefits of external shading devices, many are designed solely for aesthetic purposes without fully considering its high potential to reduce solar radiation and glare. Custom sunshades from ILI enhance building exteriors and contribute to sustainable, aesthetically pleasing designs. Beyond their visual impact, these sun control devices play a crucial role in reducing energy consumption and carbon footprint, making them a cost-effective choice for any project type.
