Electrochromic glazings: dynamic simulation of both daylight and thermal performance

Abstract

Electronically tintable glazings have now reached maturity and are part of the options to be considered in the design of energy-efficient dynamic facades, both in renovation and for new buildings. However, to assess concretely the impact of such solutions, it is necessary to carry out dynamic simulations and to consider simultaneously thermal and daylighting performance.This approach, which until now required the use of several distinct specialized tools, is now available with a single software and can be initiated at the earliest stages of design. This paper presents the new simulation possibilities offered in the last release of the DIAL+ software, and show how the tool provides a new effective way to quickly quantify the potential of electrochromic glazings regarding energy, daylight and comfort targets.
