Due to global warming, energy saving has become an ethical and economic obligation, for this reason new buildings are designed and built taking into account appropriate internal solar shading systems (see Legislative Decree 192 e Legislative Decree 311 Directive EU 2018/844) and Solaris suggests in this case blinds to save energy by responding to fundamental requirements.
Modern solar shading systems must be dynamic to maximize the use of solar energy during cold periods and minimize its transmission in the hottest months and during the hours when the sun discharges its energy on the building facade. Dynamic solar shading is able to control internal and/or external devices for solar protection - curtains, blinds, etc. - using technologies for the intelligent construction system that send an input in real time from different sensors such as sun, wind, temperature. The application of the correct solar shading allows to lower the internal temperature from 5 to 8 degrees C consequently reducing the energy consumption by thousands of kilowatts per year considering the single environment.
Energy-saving blinds are designed using appropriate simulation software to calculate the actual savings in kilowatts in the different periods of the year based on the type and fabrics (and glass) chosen. It is also possible to calibrate the room temperature according to the distance of the curtain from the window.
For each fabric and color Solaris Tende provides the various values of Light Transmission (TL) of Solar Transmission and Absorption of Solar Energy (TS and AS). Emissivity values are also available for more advanced materials.
But what are these values?
Shown on the right is the temperature diagram of a room, with or without an energy-saving curtain, for a simulated environment in a given city on June 30th at 3.00 pm.
