Bahnhofpark, Sargans, Sargans, Switzerland
A sustainable quality of life in Sargans
The new development is also intended to offer a sustainable quality of life. Some of the buildings opposite the train and bus station in the Bahnhofpark development are designed to screen the residential blocks that face onto the square. There is a green recreation area in the nearby nature park. The plans include around 8,000 m² of office and retail space in three buildings, while seven further buildings will include 40 rental apartments and 40 exclusive owner-occupier homes.
Close to surface ground energy technology
The Bahnhofpark development is currently the largest project in Switzerland to use close to surface ground energy technology (2010). Construction commenced in April 2010 and the development should be complete by April/May 2012. The general contractor is Bauengineering.com AG from Chur, while the project was developed by Swissbuilding Concept AG from St. Gallen, with Lippuner-EMT from Grabs acting as fitters and Chur-based Giubbini, ETH SIA AG providing special architectural services.
Uponor provides site services
The entire train station project is based on an ingenious building automation concept involving the environmentally friendly use of ground energy. In order to ensure long-term sustainability, the client and planner have focused particular attention on the choice of high-quality system solutions. Uponor was chosen as partners for ground energy technology. Hans Jörg Schwarz, CEO of Uponor AG, acted as consultant on behalf of Uponor.
Thermo-active piles used
The client decided to use close to surface ground energy technology, involving thermo-active piles. Approx. 38,000 m of Uponor PE-Xa pipes were used to harvest the ground energy. The thermo-active piles have already been installed on site and the foundations will then be excavated. Not only do heavy concrete components make suitable supporting elements, but can also be used effectively to store heat. Foundation piles can be used for this purpose. Each concrete surface can be designed with this in mind. The heat exchangers can only be installed while the building is under construction.
Effective and efficient use of heat
The economic benefits mainly derive from the fact that it is only necessary to use components that would have been necessary for structural engineering purposes in any case. This means that there is no need for additional drilling or installation work for ground energy collectors or probes. Close to surface ground energy technology uses the energy stored in the topmost layers of the soil to a depth of up to 400 m or in the groundwater. The temperatures of 8 to 12 degrees that apply here can be used in a variety of ways and can provide warmth and cold in order to heat and cool the building. This is an ideal solution for the design of the Bahnhofpark complex in Sargans.

La dalle active Uponor est intégrée depuis 2017 dans l’immeuble Delta Green, bâtiment tertiaire de 4600m2 comprenant 4 niveaux. Celui-ci est le premier bâtiment de la région tout à fait autonome en énergie.
Uponor were nominated as the sole supplier for radiant heating systems for the Sunesis Schools schemes, with Main Contractor Willmott Dixon. Sunesis is a Joint Venture between Scape and Willmott Dixon, built on the combined experience of public sector know-how and private expertise. They are the market leader in delivering pre-designed buildings across a range of market sectors. Every design has a defined layout, specification, fixed cost and timescale to construct. The full benefits of a full BIM model are also utilised.
Le bâtiment d’enseignement supérieur et de recherche pour l’Institut Mines-Télécom intègre un système de dalle active sur une surface de 40 000 m2. Le bâtiment économe en énergie accueillera une gamme variée d’activités propres à l’Institut Mines - Télécom : formations, recherches, transfert et innovation.
