While developing design and estimation documentation, an important factor is consideration of the so-called insolation, this means the calculation of heat mechanics of engineering systems based on geographical location of the object. At different times of the year, the building is illuminated in different ways by a stream of sunlight, which also heats the building and rooms. The calculation also takes into account the weather for the selected region. Natural lighting should be considered when designing the interior lighting of the building. Experienced electrical engineers work at SHYNDAU LLP to calculate the optimal lighting for your building.
