ABSTRACT
Climatic forces are important in architecture because a building´s response to climate is directly related to its energy consumption, and because climate is a powerful local context giving designers a means of regional expression and place making. [3] The contribution deals with a method which can be a tool how to fulfil an effort declared in European Directive 2010/31/EU on the energy performance of buildings to build after 2020 only passive houses, zero-energy buildings or active houses. Such buildings for their performance need quite significant portion of solar energy, so access to direct solar radiation is inevitable. The requirement of solar access could significantly influence existing way of urban design. Using the solar envelope method can be an answer how to insure adequate portion of solar energy. The paper contains some display of using this method – students’ projects - from a scale of a building to organizing a space in a small settlement.
