HVAC in the healthcare industry has changed quite a bit since 1889
Not an artist's studio per se, but in his 1889 "Ward in the Hospital at Arles," Vincent van Gogh depicted the interior of the hospital where he stayed immediately after his notorious ear incident, which shows numerous figures warming themselves around a stove in the foreground

German word of the day is Citymaut, a very short word for “congestion relief zone pricing.”
Eine Reduzierung des Autoverkehrs schafft mehr Lebensqualität für alle: bessere Luft, mehr Platz für Menschen, weniger Lärm und Unfälle. Eine Citymaut bringt zusätzlich noch Einnahmen für leere Stadtkassen. 👏

At Germany’s equivalent of Home Depot you can get a 445 W solar panel for €69. Nice.
Die Preise für Solarkomponenten bei #Bauhaus gehen echt.
Klar man bekommt es online billiger, aber spart sich so die Lieferung.
