There is a strong demand for accurate moisture modelling since moisture poses a risk for both the constructions and the indoor climate. Thus, in this investigation there is special focus on moisture modelling.
An efficient urban energy system could be a highly diverse and well-integrated structure of buildings and systems.
This paper presents first steps of a methodology for calibration of building simulation models through definition of the parameters that most affect the main electric end-uses of a building.
This paper presents the results of a comparison between measurements of a co-heating test in a passive house and the simulated response of the building to the same outdoor conditions calculated with the building simulation program Trnsys. Special
This paper describes the design and simulation of a hybrid ventilation system for a recently constructed circus building in Montreal. The HVAC system draws fresh air through two underground ducts which are used for preheating or precooling.
Energy and financial performance of micro-chp in connection with high-performance buildings | 2005 | English
This paper deals with the issue of using micro- Combined Heating and Power plants (mCHP) in high-performance houses in terms of energy conservation and cost savings.
This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force.
Development of archetypes of building characteristc slibraries for simplified energy use evaluation of houses | 2005 | English
For a quick and reliable energy evaluation of houses, one needs simple energy analysis software.
Building effectiveness communication ratios for improved building life cycle management | 2005 | English
Many existing building energy performance assessment frameworks, quantifying and categorising buildings post occupancy, offer limited feedback on design decisions.
Comparison of candidate materials for seasonal storage of solar heat through dynamic simulation of building and renewable energy system | 2005 | English
In a survey recently conducted by ECN and the University of Utrecht in The Netherlands [Visscher, Oonk et al, 2004]), several potential thermo chemical materials (TCM's) for seasonal storage of solar heat were determined.
A model-based method for the integration of naturalventilation in indoor climate systems operation | 2005 | English
This paper presents an in-situ calibrated model-based approach to treat natural ventilation as an integral element of the operation of the buildings' thermal systems.
An overview of an integrated building simulation tool -designer’s simulation toolkit (dest) | 2005 | English
In early 1980s, Tsinghua University has started to develop a new building simulation tool with the aims to benefit for teaching, research and practical use of HVAC related applications in China.
A simple method to incorporate thermal bridge effectsinto dynamic heat load calculation programs | 2005 | English
The aim of this study is to develop a simple method to predict heat flows and minimum surface temperatures in dynamic heat load calculation programs.
A method to verify calculation of transient heat conduction through multilayer building constructions | 2005 | English
Validation and verification of building simulation programs and load calculation programs is of continuing interest.
An evaluation of the hygrothermal performance of‘standard’ and ‘as built’ construction details using steady state and transient modelling | 2005 | English
Accurate assessment of both surface and interstitial condensation risk at the design stage of buildings is of great importance - not just to minimise the damaging effects moisture can cause to building envelopes, but also to contribute to the prov
A proposed method for generating,storing and managing large amounts of modelling data using scripts and on-line databases | 2005 | English
With computational analysis and simulation becoming an increasingly important part of the building design process, the complexities of dealing with the huge amount of data that this can produce can be overwhelming for many designers.
Tile coated wood fired appliances are designed to store heat from the intermittently burning fire in their massive structure and release it slowly to the room. The design of these systems should assure thermal comfort during the whole process and
Airflow modeling and fire smoke propagation in the new ecole polytechnique building | 2005 | English
This paper addresses the application of fire and smoke simulation and computational fluid dynamics tools to events taking place in the new engineering building on the campus of the University of Montreal.
A preliminary model of user behaviour regarding the manual control of windows in office buildings | 2005 | English
This paper presents the results of a field study of manual control of windows which has been carried out in 21 individual offices within the Fraunhofer Institute’s building in Freiburg, Germany, from July 2002 to July 2003.
