Window Energy Word List
See the Terminology
– Air Leakage Rating: the rate of infiltration measurement taken regarding the window or skylight when a strong wind appear. It measured by units of cubic feet each minute per square foot (cfm/ft2) of window area or cubic feet each and every minute per foot (cfm/ft) of window perimeter length. If your rating gained through the window air leakage is fewer, then a airtightness is greater.
– Conduction: An upright contact from heat flow throughout asolid material, as an example glass or wood, andfrom a fabric to the other in an assembly, for instance a window.
– Convection: Heat flow obtained from acirculating gas or liquid, for example the room air or windowpanes’ air or gas among it. Ottawa Commercial Glazing
– Fenestration: Aspects of interior or exterior from window or skylight,like shades or blinds. You should determine the location of an building’s windows openings being an exterior façade.
– Gas Fill: to be able to reduce the U- factor with decreased the conduction and convection, a gas will be placed within window or skylight glazing panes apart from air.
– Glazing: Window or skylight having a glass or plastic panes
– Infiltration: Unintended ventilation that comes into the building from exterior surface breaks. Several causes including, surrounding window’s joints and cracks, or skylight frames, sash, and glazing will make this event happen.
– Low-Emittance (Low-E) Coating: An virtually invisible, microscopically thin layer from metal or metallic oxide that placed withinthe surface from window or skylight glazing surface mainly to reduce the radioactive heat flow that passed the windowor skylight and resulting fewer U-factor.
– Radiation: The type of electromagnetic waves that can from unconnected surface to an alternative and transfer the temperature. The sun’s energy attains planet earth by radiation, as well as the heat from a person’s body could be loss because of a cold windowor skylight surface with a similar way.
– R-Value: A material or heat flow assembly resistance measurement. It does not take inversion of U-factor (R = 1/U) and isconveyed in units of hr-ft2-°F/Btu. A greater heat flow resistance and insulating value has higher window R-value.
– Shading Coefficient (SC): A measurement ofa window or skylight ability totransmit solar heat, compared to that abilityfor 1/8-inch clear, double-strength, single glass. It really is equivalent to the Solar Heat GainCoefficient multiplied by 1.15 and isstated as a number without unitsbetween 0 and 1. An increased shading will be gained with window which may have a lowerShading Coefficient and transmits less solar Heat.
– Solar Heat Gain Coefficient (SHGC): An absorbed andconsequently released inward, directly transmitted of solar radiation fraction that admittedover a window or skylight. The Shading Coefficient may be substituted by SolarHeat Gain Coefficient as the standard indicatorof a window’s shading ability. It isstated like a number without unitsbetween 0 and 1. A better shading will be delivered from a window with lessenSolar Heat Gain Coefficient that transmits fewer solar heat.
– Spectrally Selective Glazing: A specificallyengineered low-E coated or tinted glazingthat prevents out most of the sun’s heatwhile transmitting significant daylight.
– U-Factor (U-Value): A measurement of warmth flow rate during the entire material orassembly. It is stated in units ofBtu/hr-ft2-°F or W/m2-°C. The U-factor regularly employed to define the speed of non-solarheat loss or obtained by having a window orskylight by the window manufacturersand engineers. A much better resistance to heat flow and greater insulating value arises from less window U-factors.
– Visible Transmittance: The proportion orfraction from visible light transmitted by awindow or skylight.
Checklist Involve Design, Specification, and Installation for Window
A checklist guidance provided in selecting commercial and residential windows and skylights to the property managers, builders, architects, and also the homeowners.
With several factors and wide climate variety, occupant needs, and utility costs to think about; it may be difficult before seeking the right window.
The check boxes emerges to mark the entries throughout the selection or design procedure.
NOTE: Its not all situations can be applied with all the entry below plus a contradictive general guidance may occur since not all detailed situations goes. The users should applied those things according their needs
Valuation on Insulating and Resistance of Condensation
– Being a guidance to select the window, find the NFRC U-factor ratings and labels.
– If your heat is needed in all climates, ensure to select a double-pane windows. Decide for a low-E coatings double – or triple-pane windows with gas filling during cold climates so that you can decrease the heat loss and condensation.
– When the heat is needed in most climates along with lesser decrease of heat and condensation from frame and, choose for wood, vinyl, fiberglass, or appropriately designed, thermally broken aluminum frames windows.
– To have extra window insulation in cold climates, using heavy drapes, thermal shades, or thermal shutters can be given
Solar Control and Defense against Ultraviolet
– Being a guidance to select the window, get the NFRC Solar Heat Gain Coefficient ratings and labels.
– To cut back the obtained solar heat (SHGC under 0.4) and maintain a high visible transmittance (glass transmittance more than 0.6), decide upon spectrally selective glazings (particular tints or adjusted low-E coatings) windows.
– To lower the obtained solar heat and constraint the glare with reducing visible transmittance, choose for tinted windows.
– To minimize the ultraviolet transmission for rooms with materials that has a tendency to fade, choose for special glazings (with plastic layers or low-E coatings); consult an authority for assisting if it is a crucial matter.
Daylight and examine
– As a guidance to decide on the window, find the NFRC Visible Light Transmittance ratings and labels.
– To provide sufficient daylight levels in each and every space, opt for the window size, location, and glass type.
– To be sure maximum outward visibility, choose windows with high visible transmittances (more than 50%).
