There’s a website called Carbon Culture which shows the energy use of a building, and they have a page for Portcullis House which uses the same chimney method.

Although I doubt cooling in London is as much of an issue as Harare. https://platform.carbonculture.net/places/portcullis-house/51/ https://platform.carbonculture.net/places/portcullis-house/5... Portcullis House Wikipedia entry, though doesn’t seem interested in its energy use: https://en.wikipedia.org/wiki/Portcullis_House https://en.wikipedia.org/wiki/Portcullis_House

> Although I doubt cooling in London is as much of an issue as Harare. The climate is similar in both cities. Harare's average January (summer) daily mean is 21°C, London's (July) is 19°C. The average highs are 26°C and 24°C. The high-low range, which looks to be important so the building can cool at night, is 10°C in both.

  Harare is 15 degrees south and London is 50 degrees north of the equator. The sun is much more intense in Harare and occupies less of the day, allowing more time for the vents to cool the building. That said, this principle can be applied in London as well.

    Also London’s day lengths vary far more between summer and winter.

    Does London even need cooling on 99% of days? 25 degrees is the temperatures air-conditioners are often set to in the tropical country I live in.

      In america the standard airco setting is 18c to accommodate people in business suits. Given that London has a pretty big financial sector (with a lot of suits) they might have something similar. The same could hold for parliament.

      If your AC is producing 25-degree air, it'll be quite dry, which London is not. (But Harare is, I believe.) That said 25 should still be fine, but there are days which are 30 & humid, which are pretty uncomfortable. Not so many, but more than 1% I think. Most buildings there are also designed much more for winter. The windows seal well but often don't open that wide, and there will be a fire door making sure you can't get cross-ventilation, etc.
