Our company, Ergomasif, with its impeccable structure and experience can guarantee the final result with respect to quality, innovation, and aesthetics.

Passive solar house design is something that was used in ancient Greece. Let’s not forget Socrates solar house. Which was built to take advantage of the solar radiation in order to make comfortable living conditions all year long.

What are Passive solar systems

Passive solar systems are constructions or configurations in the south part of the buildings that maximize the use of solar radiation. A significant contribution to saving heating energy in a building is the ability to utilize effectively solar energy.

Passive solar heating systems collect solar radiation, store it in the form of heat and distribute it in the room. Every building accepts solar radiation which comes in through the openings (windows) and warms the room.

Collecting solar energy is based on the greenhouse effect and more specifically on the entry of solar radiation through glass. By living in such buildings, we can make our lives more comfortable. Protect the environment and our health thus improving our quality of life. We can, in other words, use this information in the right way.

Two of the most commonly used passive solar systems are the greenhouse and the sunroom.

Greenhouse: These are closed spaces incorporated in the southern parts of a building and are surrounded by glass. Solar heat from the greenhouse is transferred in the main building through openings or even passes through the walls.

Sunrooms: These are spaces inside the building that have a glass roof and work the same as a greenhouse. Solar energy is collected through the roof, stored in the interior, and then transferred internally through openings, while some of the energy is stored in the building components.

The percentage of the energy that perfuses, reflects or is absorbed by the glass depends on its photometric characteristics
