Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. Energy Efficiency - An Overview
US Total Energy Consumption
A Guide to Energy EfficientWindows Energy efficient windows will make your home more comfortable, dramatically reduce your energy costs and help to create a brighter, cleaner and healthier environment. All properties lose heat through their windows. But energy-efficient glazing keeps your home warmer and quieter.
Can Energy Efficient Windows be the right choice for your Home?With increasing concern about the forecasts for colder winter this year, many of the US people are worried about the sorring cost of energy bills.If you are a homeowner and worried about the rising cost of the heating bills and interested in exploring ways to ensure that your energy bill should stay on track, energy efficient windows can be major factor in your home that could help you do just that.
Design Considerations New window products and technologies have changed the performance of windows in a radical way. Issues such as climate, orientation, shading, and window area all effect the energy performance, but human factor issues such as access to fresh air, daylight, and natural views impact the comfort of a home.
Measuring Performance Heat flows through window in three ways:
Conduction Convention RadiationThree energy performance characteristics of windows are:
Insulating value. Heat gain from solar radiation. Infiltration.
Technologies The overall performance of any window is determined by the complete window assembly. Smart windows automatically respond to the climate of the place.The optical properties are achieved through electromagnetic glazings. The energy performance of a window with advanced glazings can transform energy liability of the buildings to energy assets resulting in longer-term environmental benefits due to reduced energy consumption.
How to choose Right windows for your home? Factors to check for: Low-e-glass Gas is filled between double panes of glass Ensure that no metal is used UPVC and composite frames are used Check energy rating of your window which measures energy saving efficiency.
