How schools are being built for extreme heat — without aircon
Years later, while studying abroad, Kere returned to his home village to build a light and airy school where children could learn in comfort despite temperatures that can hit 45°C.
But the Berlin-based architect did not use air conditioning. Instead he incorporated a host of cooling features into Gando Primary School that he has since applied to projects around Africa.
Kere, who won architecture's highest honour, the Pritzker Prize in 2022, is among architects pioneering sustainable school designs for a warming planet.
'My own school was so hot it was hard to concentrate,' he told the Thomson Reuters Foundation. 'So I wanted to build a school that would be comfortable and inspiring for children.'
Studies from Brazil to Vietnam show heat significantly affects learning. In a report last year, the World Bank warned climate change was threatening educational attainment, creating an 'economic time bomb'.
Experts say classrooms should be no hotter than 26°C.
In Gando, villagers were initially shocked when Kere announced he would build the school from clay, but the material is a natural temperature regulator, absorbing heat during the day and releasing it at night.
Concrete and plate glass may look contemporary, but Kere said they make buildings hot, necessitating air conditioners.
This creates a vicious circle. Energy-intensive air conditioners, which expel hot air outdoors, contribute to global warming, which then fuels demand for more air conditioning.
Instead, Kere uses passive cooling techniques.

Titan sub disaster was preventable, US finds in scathing report
The catastrophic implosion of the Titan submersible that killed five people in 2023 could have been prevented, a US coast guard investigative board found on Tuesday, calling the vessel's safety culture and operational practices 'critically flawed'. The Titan vanished during a descent to the Titanic wreck on a tourist expedition, losing contact with its support ship. After a tense four-day search, its shattered remains were discovered strewn across the seabed 488m from the bow of the legendary ocean liner that sank in 1912, claiming more than 1,500 lives. OceanGate, the US-based company that managed the tourist submersible, suspended all operations after the incident. A company spokesperson said on Tuesday the company again offered its deepest condolences to the families of those who died 'and directed its resources fully towards co-operating with the coast guard's inquiry through to its completion'. The chair of the US coast guard marine board of investigation, Jason Neubauer, said the accident was preventable. 'There is a need for stronger oversight and clear options for operators who are exploring new concepts outside the existing regulatory framework,' he said in a statement with the release of the 300-page report. Chloe Nargeolet, whose father, French oceanographer Paul-Henri Nargeolet, died on the submersible, said she was satisfied with the investigation. 'The OceanGate boss didn't do his job properly and obviously my father didn't know that,' she said. 'It was not random or bad luck, it came from something. It could have been avoided.' The board determined the primary contributing factors were OceanGate's 'inadequate design, certification, maintenance and inspection process for the Titan'. It also cited 'a toxic workplace culture at OceanGate', an inadequate regulatory framework for submersibles and other novel vessels and an ineffective whistle-blower process. The report added: 'For several years preceding the incident, OceanGate leveraged intimidation tactics, allowances for scientific operations and the company's favourable reputation to evade regulatory scrutiny.' The board found OceanGate failed to investigate and address known hull anomalies after its 2022 Titanic expedition. It said data from Titan's real time monitoring system should have been analysed and acted on during the expedition. It also criticised OceanGate for failing to properly store the Titan before the 2023 Titanic expedition. The report faulted the absence of a timely occupational safety and health administration investigation into a 2018 OceanGate whistle-blower's complaint combined with a lack of government co-operation, calling them a missed opportunity and added 'early intervention may have resulted in OceanGate pursuing regulatory compliance or abandoning their plans'.

US Coast Guard says Titan submersible's design a primary factor in implosion
A US Coast Guard investigative board concluded on Tuesday that the 'inadequate design' of the Titan submersible was a primary contributing factor in its implosion in 2023 that left five people dead. The Titan was on a tourist expedition to the wreckage of the Titanic — a British passenger liner that sank in 1912, killing at least 1,500 people on board — when it lost contact with its support vessel during descent. Its remains were found four days later, littering the seabed about 488m from the bow of the Titanic wreck. The implosion was preventable, the chair of the US Coast Guard Marine Board of Investigation Jason Neubauer said as a 300-page report was released after a two-year probe. 'There is a need for stronger oversight and clear options for operators exploring new concepts outside the existing regulatory framework,' he said. A media spokesperson at OceanGate, the US-based company that managed the tourist submersible and suspended operations after the incident, was not immediately available for comment. The board determined the primary contributing factors were OceanGate's 'inadequate design, certification, maintenance and inspection process for the Titan'. It also cited 'a toxic workplace culture at OceanGate', an inadequate regulatory framework for submersibles and other novel vessels, and an ineffective whistle-blower process. The report added 'for several years before the incident OceanGate leveraged intimidation tactics, allowances for scientific operations and the company's favourable reputation to evade regulatory scrutiny'. The board found OceanGate failed to investigate and address known hull anomalies after its 2022 Titanic expedition. It said data from Titan's real-time monitoring system should have been analysed and acted on during that expedition. It also criticised OceanGate for failing to properly store the Titan before the 2023 Titanic expedition.

Community members stitch hope for Edenvale's children in need
Community members stitch hope for Edenvale's children in need Community members and the local business Lavender and Time recently joined forces to spread warmth this winter by crocheting items for two Edenvale charity organisations. Seven blankets were lovingly crocheted for Child Welfare South Africa in Edenvale and Bedfordview, while baby beanies and baby grows were made for children abandoned at Edenvale-based Tree of Hope. The donations were handed over to Michelle dos Santos, Ward 18 committee member responsible for the women and children portfolio, who delivered the items to the respective charities. ALSO READ: Child Welfare Edenvale to hold 74th AGM on August 15 Diane Gomes, who teaches smock making, garment construction and crocheting at Lavender and Time and who was involved in the project, explained that several women who regularly meet at the store wanted to do something special for the community this Mandela Month. Diane said store owner Heather Lawlor selected the charities, and the women began working on the projects in June. Highlighting the many hours and effort involved in handmade blankets and clothing, Diane said the group wanted to give back to reputable organisations.
