It started with a laugh. How could it not, when your MC for the entire event is the humorous John Vlismas? What followed was three whirlwind days of learning, sharing, conversing, concentrating—and yes, occasionally yawning. Let’s face it: conventions are a break from the routine of everyday work life. As John quipped (paraphrased), “When else during your regular day do you insist on indulging in a delicate pastry or croissant at every refreshment break?”

But enough about the snacks. Let’s dive into the real substance of the 2024 Green Building Convention.

Day 1: A Dynamic Start

The first day of the 17th Green Building Convention kicked off with energy and warmth. From the heartfelt welcome by the Green Building Council South Africa (GBCSA) to the laughter-filled moments led by our MC, it set the tone for an unforgettable event.

One of the standout moments of the day was Chilufya Lombe’s engaging presentation on achieving Net Zero in existing buildings—a critical topic for advancing sustainability in our sector. Chilu emphasised the importance of addressing the “energy efficiency gap” in existing buildings, showcasing the need for extreme energy efficiency measures alongside renewable energy integration. By setting clear, process-driven targets and utilising data-driven optimisation strategies, the presentation highlighted how operational efficiency and innovative technologies can bridge the gap between design intent and real-world performance.

The day ended on a high note with a creative upcycling fashion show, where waste was transformed into wearable art. It wasn’t just an exercise in creativity but a reminder of the potential that lies in reimagining waste. My own entry, a chunky silver rose necklace crafted from cut-up egg cartons and a base of plastic bottle tops, was a fun and tangible way to showcase how everyday materials can find new life in unexpected forms.

The sense of community was palpable, as friends and colleagues who share a commitment to sustainability came together once again to collaborate, innovate, and inspire.

Day 2: Collaboration is Key

Day 2 of the Green Building Convention continued to build momentum. Changing gears for a moment from MC to speaker, John Vlismas opened with a thought-provoking analogy (paraphrased):

To beat the house (aka climate change), we need to change the game—from player-vs-player to a collaborative, multiplayer strategy.

Dr. Sechaba Maape reminded us of the importance of indigenous knowledge, suggesting the use of AI to understand the environmental impact of our built environment. Meanwhile, Michael Jordaan delivered a powerful message, “Ideas are great, execution is better, but sustainability is key to longevity.”

Marloes Reinink, our director, emphasised the value of Accredited Professionals at the project team table. Whether for new builds or existing buildings, their role is crucial in steering projects toward sustainable outcomes.

Annelide Sherratt, our Head of Certifications, contributed to an insightful session with V2 category directors André Harms, Francois Retief and Dash Coville, sharing strategies to navigate the updated certification tool – fondly dubbed “Taming the V2 Beast.”

The day concluded in spectacular fashion at the gala dinner, themed “Beautiful Creatures.” Our team turned heads with our “Birds of Paradise” ensemble. A highlight was Marloes accepting the Net Zero Waste award for the Liberty Two Degrees Retail Portfolio project, a collaborative achievement with Francois Retief from Sow and Reap. Truly a shining example of the collaborative strategy John Vlismas championed earlier in the day.

Day 3: Insights and Inspiration

The morning walk between our accommodation and the convention was filled with fresh air and a crisp wind which helped clear the cobwebs of the previous night’s gala dinner for the final day of the convention. The first session was a break away, and included my own presentation, titled “There’s Gold Here. Don’t Waste It!” Using the Balwin Properties Head Quarters building as a case study, the immense potential in responsibly managing construction waste was showcased.

Later, a captivating panel discussion, “Voices of Tomorrow: Young Leaders Shaping Our Sustainable Future,” hosted by John Vlismas, spotlighted inspiring youth leaders. Environmental activist Zoe Prinsloo, Sundial Movement co-founder Otsile Nkadimeng, and Eco-Soap Bank director Sharon Rapetswa shared their bold visions for a sustainable future.

Andre de Ruyter delivered a sobering yet motivating talk on decarbonisation and the Just Energy Transition (JET), highlighting the paradox of sunshine-rich regions with low renewable energy adoption. He challenged us to think beyond charity from developed nations and instead innovate for fairness and impact.

GBCSA CEO Lisa Reynolds brought the convention to a close with a rousing call to action, leaving us energised and ready to take on new sustainability challenges.

Looking Ahead

Just like the Cape South-Easter keeps things fresh, the 2024 Green Building Convention refreshed our minds and refocused our efforts. We learned from each other, shared our successes and lessons, and celebrated those who have excelled.

We also saluted the everyday heroes – the Zero Heroes – who show up daily with their sustainability caps on, driving change in the built environment.

We look forward to 2025, eager to discover “What’s next in sustainability?” Until then, let’s continue the work, keep up the collaborations, and remember to laugh. It makes the journey to zero just a little more positive.
