Window Films and Energy Efficiency in Buildings
Window films can play an important role in making buildings more comfortable and livable. Most people trying to lower energy costs in older homes will always have to face the challenge of where to start. It is a fact that windows are responsible for 25 to 30% of all the heat loss in buildings. For this fact homeowners may want to changing their windows to be energy efficient.
So what exactly makes a window energy efficient? Even more important is the question: What is Energy Efficiency?
Energy efficiency definition:
Energy efficiency simply refers to the use of less energy than usual.
This means reducing the total amount of energy to carry out the same amount of work. This will obviously provide the benefit of reduced monthly energy bills.
From this definition alone, one can see that the process to lower energy usage is not only beneficial to the homeowner but also to the overall energy supply grid. Therefore energy efficiency becomes a positive step that should be pursued even in older buildings.
As such the most energy efficient windows could offer homeowners some energy savings.
So what can homeowners in older homes do to make their windows energy efficient? The use of window films is one option that homeowners can look at to make their windows energy efficient.
The amount of radiation in a room will be less. The transferring of heat from a place with a high temperature of one of the cooler temperature is better known as heat transfer. The heat flows from hot to cold. There will be no heat transferred if there is no difference in the temperature. There are various kinds of heat transfer and these are radiation, convection as well as conduction. For window films, radiation is an essential process of transferring the heat, since it moves the infrared waves.
Window Films for Energy Efficiency in Buildings
The solar energy passing through a window is transferred by infrared waves. The radiant energy will be converted to heat when it hit a person or an object. If the transfer will be blocked the energy will be kept from turning to heat, since it will not strike into something. The window films will be the one to interfere with the transferring of the energy by reflecting the energy back. The transmission is just the amount of solar energy such as UV plus the VL (visible light) plus near infrared that passes through the windows. With window films on your windows, the parts are changed accordingly, with reflected energy and boosting absorption.
This adheres to the lessening of the solar heat transmitted in a room or in a car. The window films has a property that influence the method of transmission, absorption and reflection of the energy.
Using Window Films to Save Energy
With window films you can save around 25% of the energy cost, because of the laws of thermodynamics. It mandates an amount of energy to eliminate the heat in a room by means of an air conditioning unit. At summer time, the loads of air conditioning unit may be lessened to turn off the whole units. To save more on the energy cost, it will be best to install window films that may help in boosting the thermal comfort, lessen the glare, while lessening around 99% of the Ultra Violet radiation at the same time.
Save Money and Energy
The advancement in terms of window film technology for energy efficiency in buildings is now ongoing. It can now be a good and inexpensive option for those who wish to increase the energy efficiency of an establishment, while saving money and mother earth as well.
A film with solar protection capacity can do wonders by eliminating the unwanted solar energy even before it penetrates through the window to keep the comfortable temperature in the building. The air-conditioning will not work double time to make the entire room cool, so it will result in less energy usage and costs as well.
Different window film manufacturers offer different levels of films that can may help in aiding the energy efficiency. The most effective rejecting rate is around 75% of solar energy. The window films will be installed straight to the window glass to form a barrier to the solar energy. This has been proven more effective than the use curtains and blinds and it is also affordable compared to changing the glass. The installation must be done by a well-trained film installer to prevent bubbles and cracking of the window films.
Window Films and Energy Efficiency
Most commercial establishments are looking for energy efficient window films for their buildings. This is because they want to boost the comfort of their tenants, without compromising the natural light quality. Energy efficient films are not just good for energy saving, but they can also help in preventing crimes, protect the people from bomb blasts, graffiti management and enhanced security. Energy efficient window films are also decorative and they can improve the design and aesthetic appeal of an office.
Lessening the energy consumption nowadays is more than just a dream, it is now becoming a necessity and window films can help with this concern, while giving added security at the same time. Energy efficient window films can help you save up to a ton of air conditioning every 100sqf of glass exposed to the sun. It can also provide comfort to the workers.
