South Africa’s real-estate and construction sectors are gearing up for a marquee gathering in the built-environment calendar: the 19th Green Building Convention, organized by the Green Building Council South Africa (GBCSA). The three-day forum will be held at the Century City Conference Centre in Cape Town from 27 to 29 October 2026, drawing more than 800 participants that include owners, developers, financiers, architects, asset and facilities managers, as well as sustainability experts, to discuss how future-oriented buildings can combine heightened ecological performance with clear commercial benefits.
Why Green Buildings Make Business Sense
Framed around the slogan “The Green Revolution: From Ambition to Action,” this edition shifts the conversation from mere sustainability pledges to the concrete technologies, financing models and proven practices that are already reshaping structures and cityscapes. For investors, the emphasis is increasingly on the bottom line: cutting operating costs, boosting resource efficiency, safeguarding asset values and responding to evolving tenant demands.
Georgina Smit, chief executive of GBCSA, stresses that the economic rationale now underpins the uptake of green construction. “Most people are not going to go green simply because they think it is the right thing to do. They will do it if it makes business sense,” Smit states. “We now have the data to assure decision makers of this, and that is helping to drive change in the right direction.”
The programme will explore how sustainability is shaping investment choices by delivering lower utility expenses, greater resilience of assets, heightened appeal to occupants and long-term value preservation. The Buildings Track will also spotlight high-performance projects across Africa, assess the possibilities and constraints of artificial intelligence, and examine how occupant behaviour influences the effectiveness of eco-friendly homes.
The Century City Conference Centre offers a venue that embodies many of the principles under discussion. Situated within Cape Town’s Bridgeways Precinct, the centre carries a 4-Star Green Star rating from GBCSA and earned the distinction of being the first African site to secure the international Green Key Eco-Label. Its pedestrian-friendly layout, resource-saving infrastructure and sustainable operating practices mirror the themes of the convention.
Verifiable Green Residential Projects
Balwin Properties distinguishes itself in a sector often driven by aspirational goals by delivering verifiable green residential projects. The firm, which bills itself as the world’s largest builder of IFC EDGE Advanced-certified homes, has shown that large-scale, resource-efficient housing can be realised. Steve Brookes, founder and chief executive of Balwin Properties, explains that sustainability is integrated from the outset: “For us, sustainability is not a badge on the wall. It is designed into the home from the start: lower electricity use, lower water use, lower operating costs and a better long-term product for the buyer.”

Balwin also backs GBCSA’s Green Star New Build V2 rating system, showing the need for quantifiable performance benchmarks. “The industry has spoken about ambition for long enough. The next phase is about evidence, standards, delivery and accountability,” Brookes adds.
The event will showcase a diverse roster of speakers who will bring global insights, innovative business models and hands-on sustainability experience. Among the featured presenters are Elizabeth Wathuti O.G.W, a Kenyan environmental activist and founder of the Green Generation Initiative; Prince Mashele, a political scientist and author; Samantha Skyring, founder and chief executive of Oryx Desert Salt; and Lorne Sulcas, who will discuss nature-based leadership.
Adam Levy, the entrepreneur behind Johannesburg’s Play Braam, will address how urban regeneration can repurpose underused structures and breathe new life into city districts. His perspective is aimed at developers and investors interested in adaptive reuse and the creation of lively mixed-use environments.
The Rising Importance of Water Security
While energy efficiency and carbon mitigation have traditionally dominated green-building dialogues, water security is now emerging as an equally critical focus. Rand Water returns as a GBCSA partner for the fourth year in a row, championing its “Blue is the New Green” campaign, which highlights responsible water stewardship in both buildings and larger developments.
Smit cautions that climate threats extend beyond single structures to the supporting infrastructure. “An empty building is a property owner’s worst nightmare,” she remarks. “Climate change is increasingly becoming one of the factors that can make a building or precinct untenable,” she says. Consequently, considerations such as water resilience and reliable infrastructure are becoming important considerations in long-term property risk assessments for investors.
