Bioclimatic constructions

Comfort inside the house winter, summer

Our long-term experience in the bioclimatic constructions of houses, the right choice of materials and the cooperation with specialized architects-engineers, ensure the excellent result.

Ergomasif, with its perfect organization and years of experience, guarantees an impeccable end result. Always with an emphasis on quality, innovation and aesthetics.

The passive solar design of houses is something that was implemented in ancient Greece. The solar house of Socrates is well known, with the aim of exploiting solar radiation to create comfortable conditions inside the house in winter and summer.

What are passive solar systems?

Passive solar systems are structures or configurations on the south face of buildings. Their purpose is to optimize the utilization of solar radiation for saving energy.

Passive solar heating systems collect solar energy and store it as heat. Then they distribute it in the area. All buildings receive solar radiation. The one that passes through the openings (windows) in the interior spaces and heats them.

The collection of solar energy is based on the greenhouse effect. Especially in the entry of solar radiation through the glass.

By living inside the buildings, we can make our life more comfortable. To protect our environment and our health and to improve our quality of living. So we can use them rationally for this purpose.

Categories of passive solar systems

Windows and doors that meet this high performance criteria must have a heat loss / gain of less than 0.8 W / m2K for the entire the unit, while the heat loss/gain through the glazing must be at least Ug = 0.7 W / m2K.

One of the most common passive solar systems is the greenhouse and the solar patio.

  • Greenhouses (solar spaces): They are closed spaces integrated into south parts of the building shell. They are surrounded by glass windows. The solar heat from the greenhouse is transferred to the main areas of the building through openings. It can also penetrate the wall.

  • Solar patios: They are interior areas of the building, which have glass on their roofs. They work like greenhouses. Solar energy is collected by the glass element of the roof. Then it accumulates in the inner space of the atrium. Part of it is transferred to the interior of the building or buildings through their openings. Another part of it is stored in the building blocks.

  • The percentage of solar radiation that penetrates, reflects or is absorbed by the glazing depends on its photometric characteristics.

    g + p + a = 1
    where g : transmittance, p : reflectance and a : absorptivity
