Climate responsive design. General climatology. Outdoor and indoor climate, weather and comfort theory. Building in different international context. Meteorological and climate laws, cause and effects mechanisms. Cultural elements. Traditional architecture. Influence of actual trends in technique and society. Implementation of climate aspects in early design stages. These factors must be integrated into early planning phases, since in sketch planning the highest potential on efficiency and comfort incensement is possible. Building related climate elements, climate factors, macro, meso and micro climates. Local conditions’ site-specific potential. Interdependency of climate elements. Geographical location factors (latitude, distance from the sea, height of location, city and land site). Climate analysis provides survey of local conditions’ site-specific potential. Interdependency of solar radiation, natural lighting, air and soil temperature, absolute humidity, precipitation, and atmospheric flow. Climate-responsivity emerges in passive design aspects, e.g. orientation, building body form finding, climate zoning in horizontal and vertical space organisation, building envelope structures and in active design aspects, like room conditioning and energy supply solutions.
