The 2025 Greenovate Awards marked a decade of student-driven sustainability innovation for the built environment. Created in 2015 by Growthpoint Properties (JSE: GRT) in partnership with the Green Building Council South Africa (GBCSA), the awards continue to recognise the ingenuity of South African university students as they tackle real-world challenges in property and engineering.
Originally conceived to bridge the gap between academia and industry, the awards are now a well-established fixture in the sector, and Greenovate has grown into the country’s leading platform for student sustainability solutions.
This year's awards saw 29 students from eight universities participate, submitting projects on topics ranging from pee-cycling to the affordability of 3D-printed recycled concrete walls, how greenwashing influences building contractors, and how capital providers for affordable housing view green developments. The winners were announced at a gala dinner held in Sandton.
In the engineering category, the University of Cape Town (UCT) received top honours for a project on the feasibility of producing fertiliser from urine at public event venues such as Cape Town Stadium. The University of Pretoria (UP) claimed second place with a project on using compost to heat water to temperatures needed to ensure safe drinking. UP also took third place with a study showing that partial replacement of cement with fly ash and slag can produce more sustainable concrete without compromising structural integrity or durability.
In the property category, UCT won first place with a project on the financial benefits of certified water efficiency for residential units. UP took second for exploring atmospheric water harvesting as an alternative water supply. UCT also took third with a focus on an optimal model for living walls in the Western Cape.
The International Finance Corporation (IFC) Excellence in Design for Greater Efficiency (EDGE) Award was presented to Justine Braaf and Benjamin van Rhyn of UCT for their work on the financial benefits of water efficiency for EDGE residential units in the Western Cape.
To celebrate its tenth anniversary, this year’s awards introduced two new categories focused on implementation potential and alignment with global ESG goals, reflecting the competition’s ongoing evolution and its impact on the future of green building in South Africa.
The Sustainability in Action Award – for the engineering project with the best potential to be implemented within Growthpoint’s portfolio or systems – was awarded to Stellenbosch University’s Hannah Counihan for her project assessing non-stationary extreme rainfall and hydrological design implications in the Western Cape. Judges highlighted the project’s relevance to Growthpoint’s sustainability objectives, ease of implementation and measurable impact.
The Transformative Impact Award recognises the property, quantity surveying or construction project that demonstrates the strongest alignment with the United Nations Sustainable Development Goals and overall ESG performance. It was awarded to Viwe Duma of the University of Johannesburg for exploring investor and funder perceptions of green developments and green certification in the affordable housing sector.
Engelbert Binedell, Chief Operating Officer of Growthpoint Properties, says: "Greenovate has grown to become a platform for real innovation in our sector. Every year we see these students bring fresh ideas and practical thinking to challenges we face today, and every year their solutions are bolder and better suited to put into practice. Reaching the ten-year milestone is a proud moment for Growthpoint. We’re investing in the future of the built environment by backing the people who will shape it."
Lisa Reynolds, CEO of GBCSA, says, “GBCSA is immensely proud to be a founding partner of Greenovate, and it’s inspiring to see how the competition has grown from strength to strength over the past decade. Each year, these students remind us of the innovation and optimism shaping the future of our sector. Their solutions tackle real-world challenges head-on and spark sustainability journeys that will play a vital role in South Africa’s green economy.”
Prizes to advance planet purpose
The top three winners in both categories received a share of nearly R150,000 in prize money. Additional prizes included GBCSA Accredited Professional (AP) Candidate courses and tickets to the annual GBCSA Convention, where top students are invited to present at the Innovation Stage – a career-defining opportunity to showcase their work to business leaders and influencers. The two new awards introduced this year are each worth R10,000 and sponsored by Growthpoint.
All participants benefit from valuable mentorship, networking opportunities and expert-led workshops. They gain access to the knowledge and support needed to translate their research into practical products or services for the property industry. The programme also helps build lasting networks and partnerships among participants.
