Blaue Lagune, AT
Together with ATP sustain, ATP Vienna prepared a study for a unique European exhibition and consultancy platform for construction and real estate. In the process, an existing prefabricated house center will be extended by a building center, hotel competence center and information center. The Blue Lagoon is Europe’s largest center for prefabricated houses and calls itself the “Smart Expo”. On the 74,000 m² site in Wiener Neudorf, approx. 100 suppliers from the fields of construction, renovation/restoration and modern living will be exhibiting throughout the year. The aim of the Blue Lagoon is to present the optimal exhibition, information, consulting and service offer for all those who want to “live more beautifully faster”.
The energy concept is based on the use of solar energy, geothermal energy and waste heat generated during operation (ventilation, waste water), and thus uses renewable energies to a large extent for the operation of the new building center, hotel and information center. Hybrid collectors (PVT), which are a combination of PV modules and solar collectors and produce both electricity and heat, are used in the construction center in conjunction with an ice storage system that enables the use of very low temperatures.
The energy distribution and supply of the stores is done via a ring-shaped underground energy rail, which represents a further optimization of energy efficiency. The energy rail provides an internal energy exchange of the heating and cooling systems, energy sources and energy sinks are connected with each other and thus lead to an increase in energy efficiency and reduced operating costs. The principle of the energy rail is also implemented in the hotel and information center via energy rails inside the building.
The hotel has a waste water heat recovery system and a mechanical ventilation system with highly efficient heat recovery. Furthermore, façade-integrated PV modules and geothermal energy are used. The information center will be equipped with hybrid collectors for heat and electricity, and will be supplied by collectors in the lake and geothermal energy. In addition, the hotel and the information center have a gas boiler to cover peak loads.
To optimize the energy concept, it is possible to merge the energy lines of the building center, hotel, info center and integrate the existing heat pump into an energy network system, which allows the synergies of the energy systems to be used more extensively and further operating costs to be saved.
For the irrigation of the green areas and the cleaning of the outside areas a rainwater utilization is considered to minimize the consumption of drinking water. In summary, the project is characterized by an optimization of the building life cycle and the resulting utilization costs (operating costs, repair, maintenance, inspection, renewal).
