Energy-Efficient Windows in Sustainable Building
6 May 2016
In Ireland, conserving energy is a crucial approach when it comes to building design. The thermal performance of windows
should be high on the list, when looking to save on heating and cooling. If lacking in quality, windows and doors contribute to a large portion of heat loss and higher energy bills. In a typical building air infiltration can increase heating energy demand. Using high quality windows and doors, and installing them properly, can help to limit air infiltration along with thermal bridging. Many modern windows make use of multiple glazing panes, sealed edges, and thermal breaks that help to counteract cold weather and maintain heat efficiently. With energy-efficient windows, you can minimise the need for heating and cooling.
Utilising natural light helps to brighten any room, and it reduces the need for additional energy use. Shading the windows with curtains, shutters, overhangs, or even plants, can also help keep a building cooler during the hottest days of summer.
The object of achieving truly energy-efficient windows varies based on the kind of climate, the building orientation, and how they fit into the overall design, so the types of windows to best fit your needs should be carefully considered. For example, in cold winter climates, windows facing south capture the most heat when the sun is low in the sky, while in hotter climates north-facing windows provide more light than heat.
Invest in high-performance glass and triple glazing to improve energy efficiency and instead of basic wood frames, use wood clad with aluminium or vinyl or consider high-quality PVC for a longer lifespan and even lower maintenance. Quality materials offer the greatest results. Contact
