Heat and Moisture in Wooden Bearings of Monuments

H. L. Schellen [1], M. Spierenburg [2], A. W. M. van Schijndel [1],
[1] Eindhoven University of Technology, Eindhoven, The Netherlands
[2] 2DPA Cauberg-Huygen, Amsterdam, The Netherlands

Nowadays, thermal insulation is applied to most buildings. However, this proves to be a challenge for most monumental buildings. When insulation needs to be applied at the interior side of a building, thermal bridges are inevitable. Wooden beam ends beared in an external wall are an ... En savoir plus

Vibro-acoustic modeling, analysis and optimization using COMSOL Multiphysics

Yu Xiang [1],
[1] Agency for Science, Technology and Research (Institute of High Performance Computing), Singapore

Vibro-acoustics encompasses the study of interaction between sound and vibration. For example, sound transmission analysis is important to design vehicle bodies and building partitions, advanced noise control technologies can ease the increasing noise pollution problem in densely ...

HAMSTAD Benchmarks Using the COMSOL Multiphysics® Software Revisited

J. v. Schijndel [1], S. Goesten [1], H. Schellen [1],
[1] Eindhoven University of Technology, Eindhoven, Netherlands

Benchmarks are important tools to verify computational models. In the research area of building physics, the so-called HAMSTAD (Heat, Air and Moisture STAnDardization) project is a very well known benchmark for the testing of simulation tools. In this paper we revisit this benchmark by ... En savoir plus

Assessing the risk of cracking for wooden sculptures due to dynamic relative humidity changes

M. Sobon¹, L. Bratasz¹
¹Jerzy Haber Institute of Catalysis and Surface Chemistry, Poland

Wooden sculptures are an important part of European cultural heritage, but they are also among the most vulnerable objects to variations of temperature and relative humidity (RH). Fluctuations in the ambient environment can lead to irreversible structural and aesthetical damage. The ... En savoir plus

PIR Sensor Modeling and Simulation Using COMSOL Multiphysics® and its Ray Optics Module

M. Maaspuro [1],
[1] School of Electrical Engineering, Aalto University, Finland

PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection in building automation applications. Normally, only the binary information indicating presence or absence is used. However, an advanced analysis of the PIR sensor analog signal can results in more ... En savoir plus

The APP as a Tool, A First Principles Approach

R. W. Pryor[1],
[1] Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The app discussed in this paper is based on a COMSOL Multiphysics® 1D heat transfer model that analyses the heat flow through a double pane window, with a gas chamber between the two panes, as would normally be mounted in the wall of a building, a container or a refrigerated chamber. The ... En savoir plus

Surface to Surface Radiation Benchmarks

J. v. Schijndel [1], R. v. Eck [1], M. Klep [1],
[1] Eindhoven University of Technology, Eindhoven, Netherlands

The paper presents a student guide on how to implement surface to surface radiation within COMSOL Multiphysics® software for case studies found within the built environment. We included four benchmarks: (1) Radiation in a triangular cavity with infinite length; (2) Radiation between two ... En savoir plus

Assessing the Potential of Ventilated Facades on Reducing a Buildings’ Thermal Load Using Decoupled COMSOL Simulations

J. van Schijndel[1], C. van Dronkelaar[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Solar radiation is a prominent contributor of energy in buildings, and can be transmitted directly into a building through opaque surfaces, but it can also be absorbed by building components (i.e. walls, roofs etc.). This study discusses the use and effect of ventilated facades, with an ... En savoir plus

Simulation of IR-Heating and IR-Scanning for the Prediction of Internal Structures of Walls

M. Penzel[1], F. Müller[1], M. Zinecker[1], A. Schubert[1], O. Wuttke[2], M. Gläser[3]
[1]Technische Universität Chemnitz, Germany
[2]Wuttke Ingenieure GmbH, Germany
[3]IFU GmbH Privates Institut für Umweltanalysen, Germany

3D-scanning of rooms and entire buildings is state of the art and commonly used to obtain and save the digital building structure. This information simplifies appropriate planning for modifications, to equip rooms, for interior design, etc. With a new approach of IR-heating and IR ... En savoir plus

A Prediction of Energy Piles’ Long-Term Operation Using a Coupled Thermo-Hydro-Geomechanical Model

T. Vu [1], L. Medina [1], D. de la Cruz [1], J. Ramirez [1], B. Xu [1]
[1] University of Texas - Rio Grande Valley, Edinburg, TX, USA

An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... En savoir plus
