Which energy efficient windows are best for an eco home You want energy efficient windows, but do you need double, secondary or triple glazing, Low E coating, PVC or wooden window frames And what has solar gain got to do with it David Thorpe brings some transparency to the mystifying range of choices concerning windows and sustainable building.

We need glazing to provide both light and heat for a low energy building, to bring our fuel bills down and enhance our comfort. Were going to look at the glazing, the frame and the opening separately and find out what is the best performing window for the price as well as other ways to cut costs.

Much of what we find will also apply to exterior doors. Adobe Photoshop Text Plugins Free Download there. Solar gain. Fig. 2.

The heating effect of the sun in a building is called solar gain. It varies with the strength of the sun, its angle and the effectiveness of the glazing to transmit or reflect its energy. Energy efficient window design aims to maximise solar gain within the building in the winter to reduce space heating demand and to control it in summer to minimise cooling requirements and glare. Windows size, position and shading can be used to optimise solar gain, while the composition and coating on each face of the glazing can be manipulated to optimise the greenhouse effect. Windows admit heat and daylight differently at different times of the year and day.

If this is within 2. Quantifying solar gain. The amount of solar energy transmitted through a window is quantified by a coefficient that is called, in Europe, the G value, and in North America the solar heat gain coefficient SHGC. G values and SHGC values range from 0 to 1 a higher value indicates more solar gain. It is specified on the energy label of a new window.

The coefficient values are the sum of the primary solar transmittance T value the proportion of the total solar insulation entering through the glazing plus the secondary transmittance the proportion absorbed in the window or shading device. For south facing windows in temperate or cooler climates like ours, a G value of 0. This can be achieved with hard coat low E see below or clear glazing. Large west facing windows should be coated with low E to a G value less than 0. Energy labels the best energy efficient windows are A rated. Fig. 3 4 Energy Label for windows. Modern windows are rated by national bodies and come with a declaratory energy label. In the UK this body is the British Fenestration Rating Council BFRC. Choose windows with the highest possible rating on the label. C is the minimum level for an eco home which the Energy Saving Trust says has a payback of five or six years. The most energy efficient windows are A rated. The label displays the following information the rating level Cthe energy rating 1.

Triple glazing is the best, if you can afford it, for long term energy saving, and necessary to achieve an A rating. Try also for windows that have an inert gas argon, krypton or xenon sealed between the panes. The gas minimises the conduction of heat back out of the building, better than air does xenon is the most effective, but argon is cheapest. Ideally, the gap between the panes should be 1. It goes without saying that you should ensure that the seals are perfect I have had some windows made that leak air into these gaps you can tell because condensation forms inside the windows. It is possible to specify windows made with up to 3. Fig. 6. A low E coating on the inside of the inner pane helps reflect heat back into the building. Low E coatings. A special coating that reflects infrared radiation should be specified for the inside surface of one pane. Its called low E coating for low emissivity. In colder climates, the low E is applied to the interior, inner most surface to deflect heat back into the home, helping to reduce heating costs. In warmer climates, low E is applied to the interior, outer most surface to deflect heat out of the home, reducing cooling costs. Other coatings. A self cleaning coating can be added to the exterior face of a pane, useful for a conservatory roof or skylight. These use ultraviolet light to decompose organic materials and rain to wash them off. A huge range of further coatings is available from manufacturers e. Individual panes specifically designed for eco homes in higher latitudes have extra clear outer layers, letting up to 8. The best frames for energy efficient windows. Frames for energy efficient windows should ideally be made of sustainably sourced timber, preferably hardwood or treated soft wood. Try to avoid PVC because of its inflexibility, liability to crack and the risk of dioxin pollution with attendant health risks when it is sent to landfill, if it is not recycled at the end of its life how can you know what will happen. Basic aluminium or other metal frames are definitely to be avoided because the metal will conduct heat out of the building. There should be insulation between the inner and outer frames see Fig. There can be metal cladding or flashing on the outside of the frame, particularly the sill, to provide protection from the elements. Beware that when fitted any flashing does not constitute a thermal bridge. It is hard to find a local carpenter who can make this type of window, and they are usually sourced from specialist suppliers see below. The amount of the window opening taken up by the frame should be minimised to maximise the amount of light admittance. For example, avoid the use of grids or muntins if at all possible. Fig. 7. A modern, well sealed, double glazed sash window made from sustainably sourced hardwood. Sash windows are on the whole not recommended because of the large area taken up by the frames, and the difficulty of draughtproofing them. However, if building regulations stipulate their use, as in a listed building, it is possible to get very well performing ones see Fig. The positioning of the glazing within the frame is important. It can be positioned nearer to the inside or outside edge of the frame, or centred equally. The ideal is to have it centred within the frame when seen in cross section. Positioning it near to the exterior will reduce its performance. Window positioning. Fig. 8. Schematic layout for rooms in a home to minimise energy use for light and heat. If this is a refurbishment youre not going to have much control over where windows go someone else has already done this However, if youre working on an extension or newbuild, strive to position the windows on the south, east or west facing side. This can be combined with a pattern of room use as in Fig. Have only small windows or no windows on the north side in the northern hemisphere.
