Our client has technology to reduce the carbon footprint of buildings through passive, maintenance-free solar protection glazing that takes advantage of the difference in sun elevation between summer and winter.
The objective of this innovation is to obtain a gain in the energy performance of the building by letting the sun pass through in winter and blocking it out in summer. This type of product is intended for companies, shopping centers and communities.
The customer’s need is to have a tool for calculating the light and energy performance of his product, both to optimize the design and the sizing but also to offer estimates of performance in use to design offices and project managers. ‘work. The particularity of this project is the customer’s need to have this calculation tool certified by the Centre Scientifique et Technique du Bâtiment (CSTB). Indeed, this technology does not fit into any already standardized category of sun protection (curtains, blinds, etc.) and requires specific treatment.
Ray-traced generation of glazing characteristic curves, ie. light and energy transmitted, reflected or absorbed depending on the inclination of the incident rays. Coupling of these curves with the environmental conditions (sunshine, temperature) for a given location and façade orientation, via thermal calculations.
