Sustainability is no longer an afterthought; it has now become an essential consideration while designing and imagining the built environment. Though the construction industry is constantly churning out new projects and products, it is essential to take the right route for progress in this age of rapid technology evolutions. 

With the correct information and research, choosing sustainable alternatives, especially in fenestration systems, is not that difficult a feat. However, to make an informed decision, it is necessary to understand the key features of sustainable fenestration.


Climate-appropriate strategies:

The primary challenge to address for effective and efficient exterior facades is climate responsiveness. Choosing systems that combat the climatic drawbacks of your project location can go a long way in terms of a sustainable choice.

For example, in colder climates, heat gain is advantageous. In such scenarios, glass and window systems with a higher Solar Heat Gain Coefficient or SHGC is suggested. On the other hand, windows with low-e coatings and spectrally selective coatings effectively lower heat gain and can suit the conditions of warmer climates.

Premium and high-quality materials:

Materials that are superior in quality add to the charm of the space and ensure longer life cycles. Using sturdy, long-lasting, durable materials means fewer replacements are needed to maintain the system. This helps lower the burden on the environment by reducing the amount of material produced, processed and handled during waste management. 


Looking at project-specific impact:

Using the above-mentioned strategies can significantly and directly impact the project. Firstly, using climate-appropriate systems ensures better thermal and visual comfort. This, in turn, reduces the load on mechanical systems for lighting and ventilation. Furthermore, using materials such as aluminium, which are non-corrosive, resilient and recyclable, the cost of maintenance and replacements is substantially lowered. Aluminium systems are also easy to maintain and hence are an ideal choice for spaces with high footfall, such as academic institutions and public buildings.

Gauging long-term environmental impact:

Along with the project-specific impact, sustainable fenestration systems also contribute to long-term and more extensive environmental solutions. By decreasing the load on mechanical systems in projects, one can reduce electrical consumption and cost. Along with that, using better materials also reduces the amount of waste generated. Reduced material usage is also possible by using modular systems that allow for flexibility according to the site requirements. If these systems are recyclable or reusable, they also prove to be a wiser choice if a building needs to be demolished or refurbished.


Sustainable products often take effective measures right from the manufacturing and transportation stage and deliver superior results in lowered environmental impact. In addition, choosing such products lets you contribute to the betterment of the ecosystem.
