They are all those systems capable of controlling and optimising the entry of sunlight. It is used to reduce the energy consumption required for cooling and heating the building or home, as well as to make the most of natural lighting, among other benefits.
The sun control and protection systems are integrated into the façade together with the building’s structure, thus allowing it to adapt to the climate and the environment of the area. The sun control also works together with the rest of the systems to achieve global management of the building: lighting, air conditioning, etc.
What does it provide?
- Energy Savings. The energy consumption is reduced because of the lower consumption of lighting, heating and air conditioning. They contribute to energy savings and help to improve the energy rating of the building. This improvement in energy certification represents an increase in the property value of the building.
- Thermal comfort. The indoor temperature is regulated by keeping it between 22 and 26ºC. This increases thermal comfort and reduces the use of air conditioning systems since the façade acts as the building’s first source of energy control. In workplaces, thermal control means an increase in productivity and comfort for the workers.
- Lighting comfort. It improves visibility by taking advantage of natural sunlight. By optimising the contribution of natural light, the use of artificial lighting systems is reduced and, therefore, so is the consumption of electricity. The use of natural light improves the quality of life.
- Sustainability. Sun control provides a significant reduction in energy consumption and therefore reduces CO2 emissions. The sun control systems can be integrated into energy harvesting systems to reduce the dependence on fossil fuels. It contributes to the commitment of respect for the environment, improving sustainability and helping to achieve Nearly Zero-Energy Consumption Buildings.
But besides, the correct design of buildings and their sun protection systems affects the health, well-being and productivity of their occupants.
