What is the International Passive House Conference?

The International Passive House Conference, initiated by the Passive House Institute in Darmstadt, communicates new findings and ideas about the Passive House every year and is considered to be the networking event for the energy-efficient building scene. This year's 24th International Passive House Conference, which was to take place in Berlin in September this year, is offered as a comprehensive online conference due to the current situation.

Passive House - Building the future sustainably! - We remain with this focus and will show with a comprehensive conference programme from 20 September to 8 October 2020 how the building sector contributes to a sustainable future. Despite the Corona crisis, climate protection must continue in earnest and we are convinced that energy-efficient building is indispensable for this! This year's online programme also includes scientific lectures, virtual building tours, the ONLINE Passive House exhibition and a wide range of networking opportunities. Here you can find out about the latest findings in passive house construction and make contact with speakers, exhibitors and conference participants from all over the world!

What technology do I need?

In order to participate in the online offers of the 24th International Passive House Conference, you need an Internet-capable device (computer, laptop, tablet or smartphone), which is equipped with a microphone and loudspeaker, possibly also a camera (most pluggable webcams already have a microphone integrated). We recommend that you use a headset or headphones to participate in the online offerings, as this will ensure good sound quality for yourself and other participants.

Do you only want to watch the event and not have active conversations? Then all you need is a computer, laptop or similar with a good Internet connection and functioning loudspeakers.


Which plattform is used for the trans­mis­sion of the ses­sions?

The programme of the 24th International Conference on Passive Houses will take place in the form of interactive online webinars and online meetings.

Smaller meetings or the guided tours of the ONLINE passive house exhibition will be offered with the online meeting solution GoToMeeting. However, it is not necessary to install any software to follow the programme.

Please note: For all solutions used by us, please make sure that you allow the browser or app to access the microphone and, if necessary, the camera of your device when the corresponding query window appears. This query appears automatically the first time you use a new (webinar) platform.


technical problems? - possible solutions!

The most common problems and their causes:

No sound

You can also correct a wrong selection in the audio options of the webinar. You can usually access these via a context menu on the audio button, via a cogwheel symbol or the "Settings" menu.

  • Is your sound on or your computer sound set on "silent"?
  • Did you plug in the speakers or headphones?
  • Have you defined the correct output device for audio signals? You can usually do this in the sound settings of your computer, for example in Windows programs on the right side of the taskbar on the audio icon.
  • Many webinar platforms require you to "use the computer audio" or similar features with one click when joining the webinar. You may have clicked here? Leave the webinar for a short time and start it again.

Nobody can hear me

  • Trivial, but the most common cause: you forgot to click on the microphone icon before speaking, thus cancelling your muting.
  • No? Then maybe you have a microphone with a hardware mute, e.g. a switch on the wire?
  • No? Then you may have selected the wrong input for audio signals and must configure the microphone correctly either in the system settings of your operating system or in the webinar software. In Windows, for example, you will find the audio settings on the right hand side of the task bar behind the speaker icon.
  • You may have prohibited the webinar platform from accessing your microphone when you first installed it or when you first entered the webinar room in your web browser. You can adjust this in the browser or app settings. Due to the large number of apps or browsers, you should briefly try a search engine here: "Browser name" or "Webinar provider" plus "Allow microphone".

My camera does not film
The causes are usually the same as a lack of microphone function, see above under "Nobody can hear me".

How do I act with­in the on­line event?

Some guidelines

In general, a conference in online format is a very regular event, therefore similar rules of conduct apply here as in the "real world": discuss objectively, remain polite and please do not disturb.

To ensure that all participants have a pleasant conference experience online, we ask you to note the following information:

  • In order to avoid unintentional background noise, please always switch off your microphone during live presentations. During the scheduled discussion, you can switch your microphone on again with a simple click when you are prompted to do so and wish to contribute a contribution.
  •  If you have a question during a presentation, you can ask it directly in the chat.
  •  Of course you do not have to switch on your camera. However, turning on your camera is a nice gesture at the latest when you have feedback or questions. Do not underestimate how valuable visual feedback is for those people speaking in front of you.
  •  Experience shows that live streams are shorter than you might be used to from face-to-face events. Therefore, please make sure to keep your speeches as short as possible.
How do I give my virtual response?

During the online offers of the conference you have various possibilities to actively participate and contribute.

During the live sessions a chat will run in parallel, where you can ask general questions visible to everyone or only to the speakers. As the individual lectures have been recorded in advance, these questions can already be answered in writing by the speakers during the lecture or can be taken up in the subsequent discussion. Following the lecture sessions, further questions can also be discussed directly with the speakers.

In addition, you can use our integrated participants platform to make contact with speakers, exhibitors and conference participants from all over the world in individual or group chat. You can also arrange individual video chats.

Are private recordings allowed during the events?

Own screenshots and video recordings of all offers of the conference are not permitted due to copyright reasons.

You can view all lectures again on our on-demand platform while the conference is running and after the conference from 10 October to 1 November.

If you are interested in presentations or video material of individual lectures, please contact the speakers personally.
