Surface transfer coefficients estimation for heat conduction problem using the Bayesian framework
Julien Berger, Clemence Legros
This work deals with an inverse two-dimensional nonlinear heat conduction problem to determine the top and lateral surface transfer coefficients. For this, the \textsc{B}ayesian fr…
Searching an optimal experiment observation sequence to estimate the thermal properties of a multilayer wall under real climate conditions
Ainagul Jumabekova, Julien Berger, Aurélie Foucquier +1
The \emph{in situ} estimation of the thermal properties of existing building wall materials is a computationally expensive procedure. Its cost is highly proportional to the duratio…
An efficient sensitivity analysis for energy performance of a building envelope: a continuous derivative based approach
Ainagul Jumabekova, Julien Berger, Aurélie Foucquier
Within the framework of building energy assessment, this article proposes to use a derivative based sensitivity analysis of heat transfer models in a building envelope. Two, global…
An efficient two-dimensional heat transfer model for building envelopes
Julien Berger, Suelen Gasparin, Walter Mazuroski +1
A two-dimensional model is proposed for energy efficiency assessment through the simulation of heat transfer in building envelopes, considering the influence of the surrounding env…
Dimensionless formulation and similarity to assess the main phenomena of heat and mass transfer in building porous material
Julien Berger, Clemence Legros, Madina Abdykarim
Within the environmental context, several tools based on simulations have been proposed to analyze the physical phenomena of heat and mass transfer in porous materials. However, it…
Average reduced model to simulate solutions for heat and mass transfer through porous material
Julien Berger, Madina Abdykarim
The design of numerical tools to model the behavior of building materials is a challenging task. The crucial point is to save computational cost and maintain high accuracy of predi…
