“It’s impossible to solve our affordable housing crisis, our climate emergency, and people’s desire for improved quality of life against racism and disinvestment into separate silos.”

Adam Mahoney writes on the National Observer website (although article originally published on Grist) that the main problem driving the so-called “heat-island effect” is tall buildings.  But there are solutions as the author explains.   Tall buildings: A boon for housing, a bane for the climate crisis In the summer of 1995, Chicago experienced one … Continue reading “It’s impossible to solve our affordable housing crisis, our climate emergency, and people’s desire for improved quality of life against racism and disinvestment into separate silos.”

Making buildings greener — both in their construction and their running — could significantly affect the impact cities have on climate change

Cities are needing more buildings than ever. But buildings produce a third of global carbon emissions and the climate emergency demands a swift transition to green buildings. Energy-saving green tech and design can help a building run efficiently, but upfront emissions from construction must be considered too. Teh Shi Ning discusses the developments in Singapore … Continue reading Making buildings greener — both in their construction and their running — could significantly affect the impact cities have on climate change

With heat being an emergency for cities globally, Athens becomes the second city to appoint a chief heat officer to find ways to cool the city, beyond the obvious air conditioning in buildings

Heat is a particular problem for people in cities because built-up areas and concrete store heat from the sun, while energy use and transport create its own excess heat that adds to the natural warming effect, and there is less of the natural cooling effect of trees, vegetation and water. Athens has followed Miami-Date county … Continue reading With heat being an emergency for cities globally, Athens becomes the second city to appoint a chief heat officer to find ways to cool the city, beyond the obvious air conditioning in buildings
