- | Some engineers and architects are worried about this trend toward active cooling. But, it actually is not a big problem, IF we manage to improve building insulation (which we have to do anyway to reduce the heating demand, which will still remain to be the dominant issue with regard to the building’s energy related climate impact). | + | 2.

- | Without active cooling summer indoor temperatures will rise well above comfort levels (like in Napoli, New York and Beijing right now) because the nights will not cool down enough to initiate night cooling using opened windows. The only option left will be active cooling during large parts of the summer. | ||
- | Now let us have a look into “Southern Climates” (i.e. locations closer to the equator where active cooling is already needed under today’s climate conditions): | + | // |
- | The energy demand for cooling will naturally increase under warmer climate conditions. The future demands will be somewhat in between 50 and 150 kWh/(m²a) useful cooling including dehumidification in a Passive House (around 50% less than in not energy efficient buildings!), | + | ---- |
- | This is why it is so important to start building energy efficient buildings in new construction right now. Buildings have quite long lifespans - and modernising a mediocre building is not going to happen within 15 to 20 years after construction (it’s simply too expensive without a need for refurbishment). And it shows that it is important to introduce renewable (PV-based) electricity generation especially in the hot/dry and hot/humid areas of the planet. | + | ==== See also ==== |
