In the upcoming online event of the Gesundheitstechnische Gesellschaft (GG) on January 21, Prof. Dr.-Ing. Martin Kriegel talks about supply air volume flow and ventilation effectiveness to avoid infections. Furthermore Anne Hartmann will talk about the leakage of masks found in measurements at HRI.

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

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.

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.

You can find the underlying study in our blog.

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:

As part of the EnEff: HCBC Project, a multilevel DHC system prototype is being designed for the TU Berlin's eastern campus. The goal of the new system is to use waste heat and renewable energy sources to save CO2-emissions.

Prospectively starting with end of july, we will offer two project courses (PGET: System Simulation and Flow Simulation) on an online basis. You’ll find more information here soon.
