Welcome to the Smart Buildings digital hub. If you’ve found your way here, chances are you’d like to see a future for South African cities that is greener, more inclusive and resilient.

How do we get there? By transforming the way we design and engineer those cities … one building at a time. To do that, we need smart laws and policies as well as participation and commitment from all community partners. The Smart Buildings hub is where you’ll find the tools and information you need to play your part – whether you’re a building professional, a city official or an engaged citizen.


Embracing green building methods and technologies offers us an exciting opportunity to undo some of the environmental damage caused by the construction industry, but it’s also a chance to address some of our biggest social challenges – especially on the African continent. From reliable energy supplies and clean water, to safe, affordable housing for Africa’s growing urban population, green buildings have a vital role to play in safeguarding a better, healthier future for the next generation.

C40 Cities: Building a smarter, greener future

When it comes to the impacts and risks of climate change, cities are on the frontlines – and they must take the lead on climate action. This is why the C40 Cities initiative is connecting the world’s major urban centres as they work towards a healthier and more sustainable future. Since buildings are responsible for 39% of the harmful carbon emissions that drive climate change, transforming the way we design and build them is an important part of that future.

As members of C40, the cities of Cape Town, eThekwini, Tshwane and Johannesburg have committed to bold targets to make greener, smarter and energy-efficient buildings the new standard.

SMART BUILDINGS is spearheaded by the South African Building Programme, an initiative managed by Sustainable Energy Africa and funded by C40 to support participating cities in achieving ambitious building policies and programmes.

The project has many partners, including the South African Local Government Association (SALGA), Green Building Council South Africa (GBCSA) and the SA Cities Network.
