Unlocking Green Stars: The Secret Power of Entrances in Sustainable Building



Entrance solutions, be it sliding doors, revolving doors, or the classic swing doors, are typically seen as just the means to an end - the end being entering or exiting a building. However, in the context of modern architecture and sustainable building design, they play a far more vital role. One of these roles is aiding buildings in achieving sustainable building certifications, like the GBCSA Green Star Certificate. In this post, we'll dive into how your choice of entrance solution could help you achieve a green star.


Sustainable Building Certifications: A Primer

Sustainable building certifications, such as the GBCSA Green Star Certificate, are essential validations in today's eco-conscious world. They offer credibility to buildings and establishments that prioritise the environment and sustainability in their designs and operations. Obtaining these certifications can also translate to tangible benefits like tax breaks and enhanced marketability (just take a look at the Positive Impact Magazine).


Revolving Doors: An Energy Saver

At first glance, a revolving door might seem like a mere architectural design choice. But did you know they play a vital role in conserving energy? When compared to regular swing doors, revolving doors prevent drafts, meaning that the building's heating or air conditioning system doesn't have to work overtime to maintain a consistent internal temperature. In essence, they act as a semi-sealed barrier between the interior and exterior environments, making them energy-efficient entrance solutions.


Real-World Impact: Case Studies

Several contemporary buildings have been able to achieve sustainability certifications due in part to their strategic use of entrance solutions. Take, for example, the Standard Bank Head Office in Rosebank. Their use of high-performance revolving doors ensured minimal energy leakage, contributing significantly to their GBCSA Green Star rating.




Another noteworthy mention is the Deloitte Centre at the V&A Waterfront in Cape Town. By integrating revolving doors, and smart sliding doors that regulate entry and exit based on traffic flow and exterior weather conditions, they managed to enhance energy efficiency and provide optimum indoor comfort.

As we continue to navigate a world increasingly aware of sustainability and environmental impact, every design and architectural choice becomes paramount. Entrance solutions, far from being mere gateways, can be pivotal in ensuring a building's sustainability and its alignment with global green standards.


So, the next time you walk through a revolving door, take a moment to appreciate the ingenuity and thought behind it - it might just be the reason the building you're in is recognised for its commitment to the environment!
