4.1. Effect of the buildings’ orientation

The results in the isolated building scenarios demonstrated that the highest annual global solar radiation on the building envelope is achieved for 45 North/East (NE)/South/West (SW) and 67.5 NE/ SW orientation for the high-rise apartment block (annual global radiation 2085 MW h/a) and the row house (annual global radiation 1352 MW h/a) respectively. At high latitudes, these orientations guarantee the highest values of solar radiation on the two contiguous façades of buildings facing South/West (SW) and South/East (SE) (Chwieduk and Bogdanska, 2004; Compagnon, 2004; Yun and Steemers, 2009). The differences between the annual global solar radiations obtained for the other orientations were consistently below 2% for both the high-rise apartment block and the row houses. Therefore, it can be stated that in ro new Paper b yfor Ganew b r ielbuildings e Lo ba cca eturban a l . Bodevelopo st in g so l a r a ccesib il it y ments, their orientation does not significantly affect the annual global solar radiation incident at the buildings’ envelope. The situation is different if the building is inserted into an existing urban environment that is characterized by building shapes and functionalities that are already planned and distributed in it, which can eviTable 7 Limits of energy performance defined by the energy label for residential buildings in Norway (Standard Norge, 2014).

Energy analyses were carried out to assess the relationship between the solar potential and the energy need for space heating and cooling in the simple urban district scenarios for row houses and high-rise apartment blocks. Since the energy performance of a building depends on the quality of its building envelope coupled to its energy systems, three quality levels were established in order 37 to assess the energy implication of the enhancement of the solar potential. The three quality levels were established according to
