How to Building Envelope Controls Energy Use

By admin on January 02, 2020

This is because many commercial window films can block up to 80% of the sun’s heat and maintains interior warmth during colder months.

The use of heating, ventilation, and air-conditioning or HVAC equipment indeed plays an important role in maintaining an ideal temperature inside a room. However, relying on this can also cause utility bills to inflate, that is why many people are looking for solutions as to how to solve their increasing energy consumption without affecting the temperature inside the home or a building.

What some might not know is the fact that a facility’s building envelope is an essential factor to take note of. A building envelope, which includes the foundation, exterior walls, insulation, roof, windows, and exterior doors, acts as a barrier that maintains a comfortable temperature inside a home or a building; keeping the indoor temperature inside and the outdoor temperature outside. That being said, having the right building envelope can help cut down the energy consumption, thus reducing the utility bills.

To be able to determine whether the building has a better envelope or not, getting down to the building systems is crucial. It includes roofing, windows, exterior doors, and claddings.

Evaluate the thermal performance of the roof

When it comes to assessing the roof’s thermal performance, never miss to include the SRI or the Solar Reflective Index, as it is responsible for indicating the reflectance and emissivity. Having a roof a high SRI can reduce the heat island effect. In addition, opting cool roofs and garden roofs have advantages in energy saving, as compared to black roofs.

Make sure exterior doors close tightly

One of the biggest thermal challenges for commercial doors is the heat loss caused by air leakage. That is why making it a habit to check weather-strip between the operable sash and doorframe is truly important, along with ensuring that the exterior doors close tightly ─ to minimize HVAC losses.

Check the cladding system

The cladding system of a building is also an important factor that needs to be checked and evaluate when it comes to a facility’s energy efficiency. If the existing cladding show a sign of deterioration or whether it performs poorly then it calls for removal and replacement or over-cladding.

Check the condition of all existing windows

Maintaining a comfortable interior temperature while enjoying energy efficiency also depends with the building’s window condition. Thus, checking for condensation, air leakage, broken glass, etc. is essential. By improving the insulating power of windows, window film installation comes into play.

Why window film is important?

Aside from the known fact that window film helps in reducing solar heat gain during the summer season while decreasing thermal heat loss and keeping a warmer temperature in colder months, commercial window films, such as a ceramic window film, also come with a number of advantages.

  • It lengthens the life of HVAC equipment. Upgrading your windows with the right window film means not being dependent on the use of heating and cooling equipment. This is because many commercial window films (as well as residential window films) can block up to 80% of the sun’s heat and maintains interior warmth during colder months.
  • It decreases the use of artificial lighting. While blinds and drapes, as well as hanging curtains on, help in controlling glare and heat gain, these can result in needing more artificial lighting as the amount of natural light that comes in is reduced.
  • It reduces the plug load. Given that the installation of window film helps reduce both hot and cold spots throughout the building or home space, you won’t need to run fans and or space heaters frequently.
  • It improves the existing window performance. Due to the high initial costs and the long return of investment (ROI) window replacement can be really a tough choice. But with the window film installation, you can save yourself from the expensive window replacement. As a matter of fact, with the help of the best providers of window film in Singapore, you can be able to improve the insulating performance of your windows.
