Glazing just means the windows in your house, including both openable and set windows, in addition to doors with glass and skylights. Glazing really simply suggests the glass part, but it is normally used to describe all elements of an assembly consisting of glass, films, frames and furnishings. Taking notice of all of these aspects will help you to achieve effective passive design.
Energy-efficient glazing makes your home more comfy and considerably lowers your energy costs. Inappropriate or badly designed glazing can be a major source of unwanted heat gain in summer and significant heat loss and condensation in winter season. Up to 87% of a home's heating energy can be acquired and as much as 40% lost through windows.
Glazing is a significant investment in the quality of your house. The cost of glazing and the cost of heating and cooling your house are carefully related. An initial financial investment in energy-efficient windows, skylights and doors can greatly reduce your annual cooling and heating costs. Energy-efficient glazing likewise decreases the peak heating and cooling load, which can decrease the required size of an air-conditioning system by 30%, causing further cost savings.
This tool compares window choices to a base level aluminium window with 3mm clear glass. Comprehending some of the essential properties of glass will assist you to select the finest glazing for your house. Key residential or commercial properties of glass Source: Adapted from the Australian Window Association The quantity of light that passes through the glazing is called visible light transmittance (VLT) or visible transmittance (VT).
This might lead you to switch on lights, which will lead to higher energy costs. Conduction is how easily a material carries out heat. This is known as the U value. The U value for windows (expressed as Uw), explains the conduction of the whole window (glass and frame together). The lower the U value, the higher a window's resistance to heat circulation and the better its insulating worth.
For example, if your home has 70m2 of glazing with aluminium frames and clear glass with a U worth of 6. 2W/m2 C, on a winter season's night when it is 15C chillier outside compared with inside, the heat loss through the windows would be: 6. 2 15 70 = 6510W That is equivalent to the total heat output of a large room gas heating unit or a 6.
If you select a window with half the U worth (3. 1W/m2 C) (for instance, double glazing with an argon-filled gap and less-conductive frames), you can halve the heat loss: 3. 1 15 70 = 3255W The solar heat gain coefficient (SHGC) for windows (revealed as SHGCw) measures how easily heat from direct sunshine streams through a whole window (glass and frame together).
The lower a window's SHGC, the less solar heat it transfers to your house interior. Glazing manufacturers declare an SHGC for each window type and style. However, the real SHGC for windows is impacted by the angle that solar radiation strikes the glass. This is referred to as the angle of occurrence.
When the sun is perpendicular (at 90) to the glass, it has an angle of incidence of 0 and the window will experience the maximum possible solar heat gain. The SHGC stated by glazing producers is always calculated as having a 0 angle of incidence. As the angle increases, more solar radiation is shown, and less is sent.
