The beneficial effects are guaranteed if the sunscreen is engineered according to the latitude of the project, the local climate, the analysis of the site location, the project orientation, and the effect obtained by the sunscreen during different periods over the year depending on the building’s use.
Moreover, the aesthetic advantage of a sunscreen is appreciated both from inside and outside the building.
The use of a sunscreen results in a limited temperature increase inside the building and a reduction of the use of air-conditioning.
An external screen is indeed a more effective instrument of solar control compared to an internal screen, as solar radiation is, during summer months, intercepted prior to reaching the glass surfaces, avoiding the greenhouse effect and the ensuing overheating of the environments. Internal screens, on the contrary, allow the light to pass through the glass, requiring finally the removal of the heat accumulated inside the building by means of mechanical ventilation or air-conditioning.
Sunscreens protect objects located close to the windows against harmful ultraviolet rays and persons against glare.
Without a sunscreen the luminosity is concentrated and fierce. Without a sunscreen the glazed unit trasmits almost all the solar energy inside, overheating the interior.
Sunscreens filter and diffuse the light thowards the interior of the building. Most of the energy carried by solar rays is stopped by the sunscreen.
Without a sunscreen the glazed unit trasmits most of the solar energy inside.
The determination of the daylight factor is a key parameter to define the quality of the light in domestic or working surroundings. During engineering, the quantity of natural light and the level of illumination in the project environment need to be established through specific analysis.
The sunscreen allows regulating the light flow transmitted by the open spaces, making the premises more comfortable for those using them.
The use of sunscreens reduces heat dispersions from the openings during winter and limits the “cooling” effect caused by wind action. At the same time, If engineered correctly, it allows sunrays to reach the interior of a building during the day, creating a natural heating.
