Triemli Spital

Health Care

The Triemli Spital is a municipal company as well as the service department of the health and environment office in Zurich. This hospital has a central status with nationalwide sphere and an extensive medical and therapeutic service range. The dimension of this hospital also seems ideal nowadays: small enough in order to be efficient and manageable, big and extensiv enough in order to offer interdisciplinary services with high quality level. There are different kinds of rooms such as x-ray room, intensive care unit, emergency room, pathology, laboratory, nuclear medicine room and so on. It was opened in 1970 and contains 557 beds at the present time.

What were the challenges in fulfilling the wishes of the customer?

The components had to be fail-safe and this was the most important challenge (access control, security). Easy operation (maintenance by the technial service must be possible anytime) was also needed.    

Why was the decision for a KNX solution made?

When this project began, in 1997, the KNX system was the only well known and well proven multisupplier bus system. It is also able to control every demanded function such as blinding, lighting, and central supervision very well.
