Oct 3, 2024 · "Sustainable cooling technologies are accessible, affordable and scalable and minimize environmental impact, aiming for near-zero emissions cooling by 2050 through increasing the use of passive strategies for cooling, raising energy efficiency standards and rules for cooling equipment, and accelerating the phasing down of highly polluting ...
Climate change: 7 ways the world can cope with heatwaves | World ...
Aug 4, 2023 · Passive cooling A US study found strategies like shading and natural ventilation could reduce pressure on air conditioning by up to 80% . Simulations using weather data from 2021 found these techniques kept temperatures in apartments out of the ‘danger zone’, even without using aircon.
Passive houses are sustainable – but are they affordable? | World ...
Jan 26, 2021 · To be certified as meeting passive house standards, buildings must undergo rigorous tests set by the Passive House Institute in Germany. Passive houses consume about 90% less heating energy than older buildings and 75% less energy than the average newly-constructed building, the Institute says.
Climate change: Is air conditioning bad for the environment?
Oct 21, 2020 · Urban infrastructures with energy efficient passive cooling, such as increasing vegetation through street trees, green façades and green roofs, hold much potential for reducing cooling demand. For example, in Xiamen Island in China, the integration of green roofs reduced average land surface temperature by 0.91C.
Decarbonizing heating and cooling tech for a net-zero world
Feb 21, 2022 · In its Future of Cooling report, the IEA predicts that “without action to address energy efficiency, energy demand for space cooling will more than triple by 2050”. The good news is that innovation already exists to increase energy efficiency and decarbonize heating, cooling and ventilation, while creating comfortable, healthy indoor spaces.
