These additional packages will either be installed along with the Rcmdr package or the Rcmdr will offer to install them when it first starts up (and you should accept the offer). Many of these packages have their own dependencies, which depend on still other packages, etc. Such as tcltk and MASS, that are part of the standard R distribution), and these 2 of my book Using the R Commander.Ī general point is keep in mind is that the Rcmdr package usesĪ number of other "contributed" packages (in addition to packages, Particularly on Macintosh systems, and these are described in this document.įor more detailed basic installation instructions, see Ch. There are, however, a few installation issues, The Rcmdr package is a standard R package, and it installs and The ENERGY STAR name and symbol are trademarks registered in Canada by the United States Environmental Protection Agency and are administered and promoted by Natural Resources Canada.R Commander Installation R Commander Installation Notes The ENERGY STAR certification applies to the door, sidelite and transom individually and not the combined door system.įind more tools and information about ENERGY STAR for windows, doors and skylights in Canada. Doors, especially hinged doors, may be sold with sidelites and transoms as one combined door system. Skylights are normally sold and installed as individual units. The ENERGY STAR certification applies to each individual window unit and not a combined group.

Windows are normally sold as individual units but they can be linked together in various configurations for installation into a wall opening. A door leaf is considered a component and if installed without its original frame, it does not retain its ENERGY STAR certification.Īll products are normally designed for installation in low-rise residential dwelling in a roof or an exterior wall that separates heated space from unheated space. It may also contain a glass insert known as a doorlite. * A door leaf (slab) is an independently moving panel that fits within a frame and where the latching and locking mechanisms are installed.

Sliding glass door (single or multiple sliding panels).

Skylight (flat-glazed, domed or tubular).

Window (hinged, sliding, non-openable or “fixed”, tilt-turn).

Here are the fenestration products that can be certified and labelled for ENERGY STAR: The IGMA program certifies that a manufacturer can consistently build IG units that will not fog and whose seals will not fail prematurely. Some insulated glass (IG) units also carry Insulating Glass Manufacturers Alliance (IGMA) certification.

The National Fenestration Rating Council (NFRC)-a U.S.-based non-profit.

Windows, doors and skylights sold in Canada may be certified for energy performance by any of these accredited agencies: When you buy certified windows, doors and skylights, you can be sure that they have been tested against current standards by an accredited laboratory, and that those test results have been verified by an independent third party.

Centre-of-glass rating-an energy-efficiency value that refers only to the glass portion of a product and not the product as a whole.The higher the number, the more light can pass through. Visible transmittance (VT)-a ratio of the amount of visible light that can pass through a product.(The R-value is not part of the energy performance standards, but is often quoted by contractors and sales staff as a measure of performance.) The higher the number, the more efficient the product. R-value-a value indicating the resistance to heat transfer in square feet per hour in degrees Fahrenheit per British thermal unit (sq. ft. x h x ☏/Btu).

(This value applies to windows and doors only.)

Energy Rating (ER)-a value demonstrating the balance between U-factor, SHGC and air leakage.The higher the number, the more solar heat the product gains.

Solar heat gain coefficient (SHGC)-a ratio showing the amount of the sun’s heat that can pass through the product.

In either case, the lower the number, the more efficient the product.

U-factor-the rate of heat transfer from warm to cold areas in watts per square metre Kelvin (W/m 2K) or in British thermal units per hour per square foot Fahrenheit (Btu/h x sq. ft. x ☏).

In Canada, energy performance is rated using the following values: (Some products sold in Canada may also be tested using the standards of the National Fenestration Rating Council in the United States.) In Canada, the energy performance of windows, doors and skylights is tested using the Canadian Standards Association (CSA) A440.2 standard. How is your product measured? Rating for energy performance
