Nursery

The new nursery in the former listed building in the heart of Vilsbiburg, Germany.

Children get to play and the "well-being" technology is hidden away...

Making future-oriented use of a group of listed buildings in the historic heart of a village, directly next to the church, is by no means easy. By the same measure, demolition is also not an option. That's why in Vilsbiburg (near Landshut), Germany, the decision was made to convert the property into a modern nursery. The biggest challenge here was in terms of technical building services resulting from the need to combine a historic structure and the intended use as a nursery. The central problem was the preservation of the brickwork walls and the timber beam ceilings versus usage-aligned room temperature control and state-of-the-art sanitary installations.

Planning the preservation of drinking water hygiene

Three points had to be observed with respect to the drinking water installation: Regular cold water exchange at least every three days, a hot drinking water circulation looped-in directly up to the extraction point and consistent temperature management even in pipes which run parallel to each other: Cold water must always be below 25°C and hot water never below 55°C.

The planning foundations for the regular exchange of water were laid using Viega’s Viptool Engineering software. Calculated on the basis of DIN1988-300, pipelines with significantly smaller DNs were selected throughout. A pipe with a DN of 40 as opposed to 65 is sufficient for the main distribution lines. This reduces the standing volume in this section by around a third. The risk of stagnation and the costs involved in regular water exchange are reduced accordingly. The looped-in pipe connection up to the extraction points prevents water from stagnating.

As such the sufficiently insulated drinking water pipes from the stainless steel Sanpress Inox system together with the thermally controlled Easytop circuit control valves guarantee the high quality of the drinking water at the nursery.

Automatic flushing

Two flushing stations with Viega Hygiene+ function handle the regular water exchange. They are programmed so that flushing takes place automatically either after a defined period of time or once temperature limits have been exceeded until the stagnating water volume has been completely exchanged – a solution which is both economic and safe.
