“…Generally, the optimal glazing share shifts towards smaller AGAWs when we tilt the house toward the east or the west. Similar results were obtained by Leskovar and Premrov [4], [6], who were studying the main cardinal directions. This study also confirms that the south orientation of the main façade is the most favourable.…”

Windows are an important part of the building envelope. They are important for the energy performance of a building, since they enable passive solar gains, reduce the need for artificial lighting and enable natural ventilation. Passive design strategies are important to enhance the performance of buildings without active systems. The passive solar gains of buildings depend on the orientation of the glazing, the glazing type, the micro location and the form of the building. A study of a single family house with different deviations from the main glazing façade, that differ from the main cardinal orientation, is presented. For each case, the optimal glazing point and the optimal glazing area were examined. A southern orientation remains the most optimal for the chosen climate of Ljubljana. Buildings create an artificial environment with restricted access to daylight. To compensate natural light, artificial lighting sources are installed in the building. To illustrate the influence of windows on the energy performance in an office, the needs for artificial lighting were observed. The energy demand caused by the electricity consumption of artificial lighting is substantial, so the positioning of windows and the visual transmittance are of great importance. Beside the size of the window, its form and height plays an important role. Windows also affect the well-being of the occupants. Most of these effects are connected with providing light, natural ventilation and communication with the outside world. These aspects are also present in sustainable building certification schemes. An overview of the health-related topics presented in different certification schemes connected to windows has been made. We have compared different certification schemes in how they deal with issues of light.

“…The infl uence of the AGAW value on the energy need is analysed in details using the climate conditions for Ljubljana in Žegarac Leskovar and Premrov [20]. The presented calculations demonstrated that the glazing size of AGAW = 35% placed in the south façade of passive timber-glass houses leads to minimum values of the total annual energy need for heating and cooling (Q h +Q c ).…”

“…In the early design stage, when determining the building geometry which can be either compact (square, rectangular) or dynamic (L, U, T-shape), it is important to consider direct solar penetration through the glazing in the south façade which signifi cantly depends also on the so-called self-shading, parametrically analysed in [17]. In the presented research the study from [20] was extended and upgraded in [17] where it was concluded that the value of AGAW = 35% is the optimal size of glazing placed in the south façade of the passive type of timber-glass buildings in basically every climate condition considered (Ljubljana, Munich and Helsinki) and any shape of the building.…”

“…In general the most significant important factors that impact on energy consumption are: location and climate data of the building, orientation of the building, installed materials, building design and the selecting of the technical systems (Leskovar, & Premrov, 2011).…”
