Was bedeutet #Alarmstufe des #Notfallplan Gas für Museen, Bibliotheken und Archive? Endlich Erkenntnisse von Forschung und Wissenschaft in ihren Betrieb übernehmen! 🧵 1/18 @VDR_Bonn @ICOMDeutschland @museumsbund @BundesKultur @BMWK @Erhard_Grundl @dpwes bundesregierung.de/breg-de/suche/…
Hintergrund: Museen zählen flächenbezogen zu den grössten Energieverbrauchern im urbanen Umfeld. Verbräuche von über 300 kWh/m2a sind normal. Neubauten wie das derzeit im Bau befindliche Museum des 20.Jhdts in Berlin werden deutlich mehr Energie verbrauchen. 2/18
Verantwortlich dafür sind die Feuchte- und Temperaturkorridore der Klimaanlagen, die sich am technisch Möglichen und nicht am konservatorisch Notwendigen ausrichten und seit Jahrzehnten nicht mehr den Stand der Wissenschaft entsprechen 3/18
@prof_nch (1/?) Profs thinking it’s ok to exercise privilege & unmask to teach in indoor classroom of students who must attend or possibly fail class—either have COMPLETELY NO understanding that 1)#aerosol is main transmission route for #COVID19; 2) how aerosol transmission actually works;

(2/22). ¿Qué es la Luz Ultravioleta?
Dentro del espectro electromagnético, en la
zona no visible, encontramos las longitudes de onda
comprendidas entre los 10 y los 400 nanómetros, donde encontramos la luz #UVA,
#UVB y la #UVC

(3/22) ¿Por qué la UVC es tan especial?
La #UVC se sitúa en el rango de longitudes de onda entre 100 nm y 280 nm. Dentro de este rango UVC, la región situada 220 nm–280 nm se considera #germicida o #GUV por sus siglas en inglés (Germicidal UV)

Whole building system metric needs to be done to improve energy efficiency, but comes with some challenges.
