Optimal control of window coverings can increase occupant comfort (visual and thermal comfort) while saving building energy use (lighting, cooling, and heating energy). [7] Typical dynamic window coverings include automated blinds and automatic shades. Window blinds and shades can be controlled to avoid glare while introducing daylight to the ...
Placement of room-types, internal doors and walls, and equipment in the house. Orienting the building to face the equator (or a few degrees to the East to capture the morning sun) [9] Extending the building dimension along the east–west axis; Adequately sizing windows to face the midday sun in the winter, and be shaded in the summer.
Brise-soleil can comprise a variety of permanent sun-shading structures, ranging from the simple patterned concrete walls popularized by Le Corbusier in the Palace of Assembly [3] to the elaborate wing-like mechanism devised by Santiago Calatrava for the Milwaukee Art Museum [4] or the mechanical, pattern-creating devices of the Institut du Monde Arabe by Jean Nouvel.
Various window blind styles. A window blind is a type of window covering. [1] There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats.
Some smart windows can self-adapt to heat or cool for energy conservation in buildings. [5] [6] [7] Smart windows can eliminate the need for blinds, shades or window treatments. [8] Some effects can be obtained by laminating smart film or switchable film onto flat surfaces using glass, acrylic or polycarbonate laminates. [9]
Each disk is proposed to have a 0.6-meter diameter and a thickness of about 5 micrometers. The mass of each disk would be about a gram, adding up to a total of almost 20 million tonnes. [ 11 ] Such a group of small sunshades that blocks 2% of the sunlight, deflecting it off into space, would be enough to halt global warming. [ 12 ]
Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [ 2 ] [ 3 ] [ 4 ] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo.
It becomes less significant in situations where direct sunlight is not a major factor (e.g., windows completely shaded by overhangs). Window design methods have moved away from Shading Coefficient to Solar Heat Gain Coefficient (SHGC), which is defined as the fraction of incident solar radiation that actually enters a building through the ...
