A simulation-based framework for design and control a dynamic facade using Honeybee[+]

I want to share with you two papers for controlling dynamic shading which I presented on BauSIM 2018 and PowerSkin 2019 conferences.

  1. Exploring the potential of the dynamic facade simulating daylight and energy performance of complex fenestration systems (venetian blinds)
  2. A simulation-based framework exploring the controls for a dynamic facade with electrochromic glazing (EC)

In order to find an effective control strategy for dynamic facades such as a complex fenestration system (e.g. venetian blinds) or a switchable window (e.g. EC), these papers proposed a simulation-based framework that explores different scenarios for the most appropriate window states.
By using a weighted penalty function method the multi objective criteria for providing visual comfort, thermal comfort and energy saving have been defined.

For these studies I have used Honeybee[+] to generate day lighting annual results (3 phase method).

This paper also addressed a common error of simulating dynamic facade, “thermal inertia and initialization issue”, and a method to overcome.

Thank you all.



The paper presented by Fazel at PowerSkin 2019 in Munich, was awarded the prize for the best presentation. (cc @mostapha).


Very nice! Congrats @fazel.ganji! Looking forward to read your paper.

Hi @fazel.ganji
Can you explain why you used 3 phase method for the first pepper? Given the complexity of the fenestration and shadings, why not use 5 phase method?
I also wanted to know do you have the BSDF materials that you used in the paper? Does anyone have all the BSDF files related to electrochromic? I unfortunately can not access the LBNL Windows software!
thanks in advance
