System Simulation in Buildings 2006 - Proceedings of the Seventh International Conference, Liege, Belgium

In 2004, the Belgian government commissioned the International Polar Foundation to design and construct a new research base in Antarctica, to become operational during the International Polar Year at the end of 2007. From the early start, there was an ambition to create a highly selfsupporting research base.
The first step in the design was to determine the basic shape of the building. Numerous wind tunnel tests were carried out to define the impact of the shape on snow built-up and aerodynamic forces. A second step was a parametric study of the building properties. Quick and basic simulations were carried out with the software <Virtual Environment>. On the basis of the result of these simulations it was concluded that the base could be kept comfortable during the local summer season by sole use of passive solar energy.
A detailed inventory of possible energy production and storage technologies led to a solar/wind energy concept. The active use of solar energy for snow melting and water heating substantially lowers the electricity demand. The recuperation of wastewater for toilets after a bio-treatment reduces the overall water consumption. Wind turbines (48 kWp installed power) and a 10 kWp photovoltaic system will be combined with a battery or hydrogen storage in order to supply all the electricity needed.
A TRNSYS model has been built up, taking into account all components such as the building, water consumption, research facilities, wind turbines, photovoltaic arrays and storage. The advantage of one integrated model is to be able to carry out a detailed sensitivity study for climatic and occupancy influences and emergency situations. This paper describes the modelling of different components and the design consequences of the harsh conditions in the Antarctic region.
