Energy Efficient Windows in Your Home
Your windows are one of the most important features affecting the comfort and energy efficiency of your home. Windows are the fenestration, or openings in a building, and are crucial to ventilation, lighting, and comfort.
Old, leaky, or failing windows account for a large portion of wasted energy in buildings. In winter, warm air leaking out around the cracks in your windows or windows blocking solar rays means more energy is required to heat your home, resulting in higher utility bills. In the summer, cool air will escape in the same way and outdoor heat may not be reflected by your windows, increasing your air conditioning costs.
The performance of your windows are affected by three main factors: air, heat, and solar radiation.
- Air flow that is encouraged through an open window is ventilation. Air flow through a closed window that leaks will decrease energy efficiency.
- Heat moves from a warmer area to a cooler area naturally. The purpose of a properly functioning window is to minimize the heat transfer occurring between different parts of your home.
- Solar radiation from sunlight can pass through the glass of your windows and warm the air inside of your home. This is beneficial in winter, as this natural heating can help to reduce your energy costs. In summer, it is desirable to reflect as much of the solar radiation as possible back outside.
Various parts of your windows work together to control air, heat, and solar radiation, minimizing the impact of external weather conditions on the temperature of the interior of your home.
Energy Star Certification
Energy Star® is a federal program that determines where a variety of products, including front doors, exterior doors, and interior doors, meet certain energy efficiency standards. Products that achieve specific benchmarks can display the Energy Star label.
Bavarian Window Works is a registered Energy Star company and offers an extensive roster of products and options that meet Energy Star standards from our showroom in Kitchener. With doors, the Energy Star standards will vary by climate.
