Zürich Kreis 4
Air conditioning and refrigeration for Kreis 4 – Werd, Langstrasse, Hard
Restaurants, bars, small shops and many apartments in a confined space: in Kreis 4, air conditioning technology must be powerful while also showing consideration for the neighbourhood.

Kreis 4: Aussersihl
Kreis 4 (Aussersihl) comprises the statistical neighbourhoods of Werd, Langstrasse and Hard. It is one of the most densely built-up parts of the city; perimeter block development with courtyards is typical.
For restaurant and shop premises, a reliable system is what counts most – in summer, a fault is noticed immediately. Maintenance during quiet periods and a contact person for repairs are therefore just as important as the installation.

Permits and noise protection in Kreis 4
In courtyards with many windows, noise protection is the central issue. We calculate the location in advance and suggest sound insulation measures if necessary.
In the Canton of Zurich, many air/water heat pumps can be installed under the notification procedure (placed indoors or outdoors up to 2 m³); in core zones and in areas with townscape or monument protection, outdoor units still require a permit. A noise protection certificate is always required for air/water heat pumps (Canton of Zurich). The City of Zurich accepts projects subject to notification via eBaugesucheZH; we compile the documents for you.
