If you have been wondering how installing new windows or modifying existing ones can help minimize utility bills, here are 5 ways windows can improve energy efficiency.
1. Windows Prevent Heated air in the Building From Escaping to the Outside
Well insulated windows ensure that heated air inside a building stays indoors. Power bills can increase significantly if the windows have leaks or poor insulation. By sealing in the warm air, the work of the heating system will be reduced and this is what leads to energy efficiency. Whether you are using an electric heater, wood stove, gas or oil furnace, having well insulated windows with no leakages will help you tame runaway heating bills.
2. Windows Prevent Cold Air From the Outside From Getting Into the Building
The heating system of a building keeps the rooms warm by heating the air circulating in the building. Depending on the volume of air in the building, this will take some time. However, heating up the building may take much longer if cold air from the outside finds its way into the house. Having poorly insulated windows that also have leaks will force your heating system to work harder to keep the building warm. This leads to energy wastage. Energy efficiency can be improved by installing better windows as well as insulating the windows properly.
3. Windows Can Help Cool the House During Summer
During hot summer months, the air conditioning system works overtime to keep the temperatures inside a building at the desired level. Since outdoor temperatures are usually cooler than indoor temperatures, opening the windows can be very helpful as far as temperature regulation in the building is concerned. All you need to do is open the windows during the day for air to flow freely into and through the building. This will ease the pressure off the air conditioning machine thereby contributing to energy efficiency.
4. Transparent Windows Allow Sunlight to Get Into the House
If you live in the southern hemisphere, opening the blinds covering north facing windows will allow direct sunlight to get into the house. On the other hand, south facing windows in buildings located in the northern hemisphere may have the same effect. The sun’s rays will heat up the building and raise its internal temperatures. This will reduce the workload of the heating system.
5. Windows Provide Natural Light
Windows and skylights can provide natural illumination in buildings. This can reduce the energy needed to light up a building during the day, hence contributing to energy efficiency. Usually, a lot of energy is wasted during the day as artificial lighting is used to provide illumination. This should be avoided where possible.
