At the beginning of the design of the winter garden it is necessary mainly to solve the problems of overheating and good ventilation. We choose types of glazing and methods of opening and ventilation. We must take into account the orientation of the building site to world parties. Reflective glass is often used on the roof of this building to reflect the greater part of the heat radiation. At the same time there is no overheating of the interior.
Solar radiation and heat in the summer permeates mainly the roof, because the sun is high. In winter the sun is low, so its rays can pleasantly warm the interior through the walls. The walls of the winter garden are therefore mostly not used reflective glass.
A number of ventilation elements must be provided for the Winter Garden. If we want to grow plants, air humidity must be higher.
