A room with a view. The commission started with a collection of rooms, which were scattered around the site looking for good views.
Radiation. Radiation is a process of energy transfer by which energy is transmitted through electromagnetic waves, not needing a material medium to transfer heat.
Radiant rooms. Sun radiation penetrates the room through the window which, through direct radiation and greenhouse effect, heats-up the concrete floor and walls, storing energy. Insulation, through external wood cladding, prevents stored heat from dissipating. Combining window radiation collection with interior thermal storage and outdoor thermal insulation, the thermal performance of the room is enhanced.
Concrete wooden-clad rooms. Reinforced-Concrete, has a high thermal effusivity (2036 s1/2 W/m2 0C) and therefore has a high thermal storage capacity. On the other hand wood and projected cork have a low thermal effusivity (500 s1/2 W/m2 0C) and therefore are good insulator. The combination of both maximize energy storage, minimizing winter losses.
Negotiate between solar radiation and views. The project negotiates between the forest views and the sun orientation. According to Edward Mazria, a solar window with “variations to the east or west of south, up to 300, will reduce performance only slightly”.
Summertime. Solar rooms, in summertime, cast a pattern of shadows which, in combination with the pine trees, offer comfortable ambient for summer activities.
Active systems. The use of active radiant surfaces seeks to champion same thermodynamic strategies for active and passive systems, looking for a synergy between form, material systems, environmental systems and user performance.
