The use of daylight is one of the priority targets of The Optimum House. Daylight controls human life processes, it affects blood circulation and improves work efficiency. Daylight in the Optimum House is provided by transparent components, but translucent materials can also be used in specific situations. One of the important guidelines here is situating the windows and transparent doors to achieve daylight penetration of living spaces at least from two sides.
Both the direct and indirect (diffuse) components of the daylight are key factors for pleasant interior conditions. In each particular case (local circumstances), the allocation and size of windows and transparent doors, which, from the point of view of daylight transportation, should be as large as possible, and harmonised with other functions of the building’s outer components, i.e. internal heat trapping and protection against heat loss. This planning is done by adjusting the energy concept to a specific location.
