pyViewFactor

Dans la continuité des stages de Marc ALECIAN (2021), puis Mina CHAPON (2021), un outil Python a été développé pour calculer les facteurs de formes de rayonnement entre « facettes » planes.

Incontournables dans la détermination de la température moyenne radiante, les facteurs de formes sont un paramètre de première importance dans la détermination du confort thermique, notamment pour le rayonnement CLO & GLO (plus d’explications sur la page dédiée : Calcul de la MRT).

Après avoir été présenté à la conférence IBPSA France 2022, le code est désormais disponible sur Gitlab : https://gitlab.com/arep-dev/pyViewFactor et sur PyPi avec un simple pip install pyviewfactor !

IBPSA France 2022

AREP L'hypercube attended the IBPSA France 2022 conference (at Châlons-en-Champagne, may 19th-20th), to present a paper entitled " Computation of View Factors between polygons - Application to urban thermal and comfort studies« .

Work is underway to make these codes open-source, as a Python library - Stay tuned! Stay tuned!

IBPSA 2021 Conference

We will be participating to theInternational Building Performance Simulation Association conference in Bruges in September this year.

Three paper will be presented, exposing part of the research done last year:

  • Urban Heat Island modeling with: Simulation of outdoor thermal comfort: A tweak with EnergyPlus
  • Spatialised computation of indoor comfort levels in semi-open spaces: Spatial distribution of thermal comfort: A case study in Paris’ station
  • Infrared radiation and polymer materials such as ETFE: A Spectral Model for Longwave Radiant Heat Transfer: Influence of New generation Polymers in BES

"Building Physics" publication

This post promotes a non-commercial announcement!

The result of a year's work is an open-source book published by a member of the team, dealing with problems in building physics and soberly entitled:

« Building Physics – Applications in Python »

The main features of the book are the following:
