In the upcoming online event of the Gesundheitstechnische Gesellschaft (GG) on april 22, microbes in the building context is the theme. Beginning with COVID and a discussion about it, Dr. med. Hugentobler will talk about research deficits at the interface between building technology and people, explaining a new understanding of hygiene, which understands buildings as ecosystems.

The participation is free of charge. A registration is required: https://www.ggberlin.de/veranstaltungen.htm [43]

In the upcoming online event of the Gesundheitstechnische Gesellschaft (GG) on march 18, selected aspects when inspecting evaporative cooling systems according to 42nd BImSchV is the theme.

In the upcoming online event of the Gesundheitstechnische Gesellschaft (GG) on december 10, Dr.-Ing. Valeria Hofer talks about the interaction between heat sources and the low-turbulence unidirectional flow in cleanrooms. A new design aid called "contaminated volume" for the selection of the supply air velocity is presented and the energy saving potential is considered.  

The participation is free of charge. A registration is required: https://www.ggberlin.de/veranstaltungen.htm [53].

The language of presentation is german.

Our area of expertise is now called "Energy, Comfort & Health in Buildings".

An Exemplary risk assessment for different everyday situations will be published soon in the current edition in HL [56].

You can find the underlying study in our blog [57].

A new article is available about the number of particles loaded with SARS-CoV-2 in the room air and its inhaled quantity, and the evaluation of the risk of infection to infect yourself with Covid-19 through them. You will find it here:

Usually,  displacement  ventilation  is  characterized  by  a  higher  ventilation  effectiveness  than  mixing  ventilation.  Is  it  therefore  a  better  prevention  of  airborne  infection? More information on our blog:
