How the mountains of The High Tatras define the scale of the built environment, is extreme: the building as well as human seems pointlike. This phenomenon forces us to act humble, to avoid every unnecessary architectural motion.
The impressive environment leads the human viewpoint back to its contemplative attitude.
The built environment is formed essentially by the elements of the nature. The sun, the wind, the temperature of the air together shape the form, these elements define from outside the elemental geometry of the building shell. This basic volume will only be refined by the logics of the inner construction, and results a living functional unit.
Analysing the path of the sun and the shading effect of the mountains, it can be defined, that on 21st of December the plot is directly lighted from 8:00 to 12:40, in a maximum of 17,28° angle of incidence. On the 21st of June, direct sunlight comes in a maximum of 64° angle of incidence from 4:55 to 18:20. The best intensity is provided during the noontime, which is only slightly effected by the mountains in the afternoons. That is why the southern building orientation is self-evident, if we would like to maximize the incoming sun radiation. Considering the annual light incoming and the heating needs, the optimum angle of a solar roof is 49,36°, which is the perpendicular value to the average angle between the two above mentioned marginal values.
A streamlined, curved building mass is ideal because of the strong northwestern, north-northwestern wind. The surfaces which sustain increased cooling down and the directions which are exposed to snowdrifts together specify the functional disposition of the building. These define the access points to the building as well. The structure as a whole resists to the forces of wind-pressure and wind-suction.
In order to minimize the surfaces which are exposed to cooling down, the shape of the building has an almost circle-formed layout. The way how the solar roof is split from the cylindrical building mass, is made by a simple section plane, therefore it is easy to construct and also minimize the geometrical heat loss and thermal bridge effects at structural joints. The 17° of roof pitch angle on the smaller roof surface was defined by combining two considerations: the optimalization of the surface area of the solar roof and the good disposition of inner spatial functions.
