House in Cisnadioara / natural slate floor
Natural slate floor in the living room. The living room is oriented towards the south and has large glazed surfaces which allow the incidence of solar radiation, thus providing suplimentary thermal energy (greenhouse effect) during the winter months when the sun is lower in the sky, heating the entire dark coloured slate floor.
The slate floor, together with the gypsum screed with floor heating, becomes a thermal buffer. During the summer month, with the sun higher in the sky, the windows are shadowed by a large roof overhang, thus preventing the over-heating of the room.
