Knoll Logistics

The Salzburg company Knoll Logistik GmbH & Co. KG, founded in 1933, bought the property in Puch near Hallein in 2019 in order to build a new company headquarters there with more space and better Autobahn connections. Since the company specializes in heavy and special transport from Salzburg throughout Europe, this was an important improvement for business development. The Knoll company offers heavy transport, crane rental, assembly and warehouse logistics. The latter now has a hall area of 8,000 m² and an open-air warehouse of 3,000 m². The area is energy self-sufficient, the buildings are heated using concrete core activation and surface collectors. In addition, two photovoltaic systems with 200 kWp each were built. The new 15,000 m² site now houses the above-mentioned storage areas, inside and outside, as well as parking spaces/storage spaces and the company's offices.

The energy supply for heating is provided exclusively via a heat pump system with a surface collector under the floor slab and partly outside on undeveloped areas. In the office area, the respective concrete ceilings with heating direction from top to bottom serve as heat-emitting surfaces. In the hall areas, the floor slab in contact with the ground and thermally insulated towards the bottom is used. Hot water is prepared centrally for the office wing using a hot water boiler. In general, small hot water consumers further away in the hall areas are provided with electrical under-table storage.

The thermally activated concrete masses are also used to control the temperature of buildings in the warm season. This is done using passive cooling via the surface collector in the ground. In the spirit of the economical use of energy, especially cold energy, no further building technology systems were built to cool the building (with the exception of server room cooling, etc.). The heat is provided by two heat pumps connected in a cascade, each with a heating output of 90 kW. These are located in the technical room in the basement of the office building.

In summer operation, passive cooling takes place via a separate cooling module. In this operating mode, the heat pumps are not active and energy is only exchanged via the cooling module. The electrical energy required here is limited to the power consumption of the circulation pumps. Adapted to the foundation situation, the surface collector is arranged in six zones, partly under the building and partly under the parking area. The shafts are waterproof and designed for truck access.
