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

An alternative white paint for buildings containing barium sulphate could be more effective at reflecting the solar radiation than traditional gypsum paint

We are always interested in new innovations. Andrew Parnell, Research Fellow in Physics and Astronomy at the University of Sheffield discusses the impact of using an alternative white paint containing barium sulphate (BaSO₄) that could be even more effective at reflecting the solar radiation hitting buildings back into space. The article is on The Conversation … Continue reading An alternative white paint for buildings containing barium sulphate could be more effective at reflecting the solar radiation than traditional gypsum paint

Many Canadian condominiums opting for geothermal heating and cooling

While most geothermal systems in the past 40 years have been installed in single-family homes, those in the industry say growth in the market is now driven by condominiums. Emily Chung writes on the CBC website about the increasing interest in this technology. What are your views?   Why geothermal is a hot trend in … Continue reading Many Canadian condominiums opting for geothermal heating and cooling

Generations after people learned to make ice in the desert, the same technique under development to provide us with radiative cooling

Sarah Kaplan writes on the Washington Post website about the innovation from one scientist at the University of California at Los Angeles to use ancient techniques to demonstrate  electricity-free electricity. It will be interesting to follow these developments in the future.   Bringing the chill of the cosmos to a warming planet Long ago, in … Continue reading Generations after people learned to make ice in the desert, the same technique under development to provide us with radiative cooling

A new type of air conditioning that uses much less energy

Chilled panels use less energy than conventional A/C and work in open spaces. The new technology is described in a news item on the University of British Columbia website. This ‘Cold Tube’ can beat the summer heat without relying on air conditioning Many people beat the summer heat by cranking the air conditioning. However, air … Continue reading A new type of air conditioning that uses much less energy

Air conditioning: definite benefits but at a cost

More and more we are having to address cooling, particularly as high temperatures are plaguing many countries, as we have seen this summer in Europe. Carine Sebi, Assistant Professor – Economics at the Grenoble École de Management (GEM) provides a good review of the current situation and future possibilities in an article on The Conversation … Continue reading Air conditioning: definite benefits but at a cost
