How Europe could slash its cooling footprint with chilled water

As climate change warms the world, we increasingly need to find ways to efficiently cool our buildings—whilst also lowering our emissions to attempt to halt the temperature rise as much as possible. Traditional air conditioners ...

Using heating systems to provide effective cooling

Climate change is causing a persistent increase in the number of hot summer days. Offices and homes are getting hotter, and the nights bring little respite from the heat. Against this backdrop, a significant increase in new ...

Calculating the rising energy demand for cooling

Due to climate change, the average global temperature will rise in the coming decades. This should also significantly increase the number of so-called cooling degree days. These measure the number of hours above a certain ...

Longer range for electric cars

If electric vehicles are to achieve greater distances, it's not only a matter of optimizing their batteries. Instead, the entire power train has to be improved. A Fraunhofer team is therefore developing electronic control ...
