Windows are important accessories for steel buildings. Aside from ventilation and adding curb appeal, their benefits include promotion of good health and productivity to the building inhabitants.
However, windows can also be major sources of unwanted heat loss during winter and heat gain during summer. That’s why it is crucial to choose high-performance energy efficient window systems to cut on electricity costs, enhance the comfort of interiors and prevent condensation for steel buildings.
Over the years, new technologies in window design have been developed, all geared to dramatically reduce heat transfer. Now, how will you know if a window system is energy efficient? A window system approved by Energy Star is a fool-proof feature that is sure to bring down your power bill.
When a product has an Energy Star label, it means that it meets the energy efficiency specifications established by the EPA. In general, these specifications include the ability of the product to:
- prevent build-up of water
- block unwanted heat from the sun
- allow any form of light to pass through
- inhibit air leakage
Energy-efficient window systems for steel buildings are made up of:
- multiple glass panes
- high-quality structural frames
- coatings that reflect UV rays
- gas fillings between panes for insulation
Ultimately, the choice of window systems depend on factors such as building use type, the prevailing local climate, the current utility rates and the building orientation.
If all these aspects are taken into consideration, then owners of residential steel buildings can expect a reduction in their energy consumption from 10%-50%. On the other hand, their counterparts in the commercial, industrial and institutional sectors can potentially slash their energy bills from 10%-40%.
Initially, energy-efficient window systems for steel buildings may cost a lot. But the investment will pay for itself in the long run in terms of continued savings in electricity costs.
