Numerical modelling of air flows in buildings and design of a data base of experiments | 1995 | English
Teaching building simulation with the help of general purpose dynamical modeling software | 1995 | English
Learning how to model and simulate dynamical systems such as a building does not have to be restricted to specialists who have learned the physics, applied mathematics, and engineering necessary for the task.
Simulation of dynamic moisture transport processes in building structures under varying conditions re- the solution of the partial differential equations of coupled moisture and heat transport. Our research focuses on the moisture transport equati
Thermal bridge (cold bridge) assessment is becoming more important for two reasons: firstly, as legislation and energy awareness lead to increased insulation levels, so losses due to cold bridging form an increasing fraction of building heat losse
The fundamentals of a probabilistic approximation in thermal buildings analysis is here briefly presented.
As introduced in a paper in Building Simulation '93, the training of users; of simulation based thermal performance assessment tools is central to the efficacy of such tools within professional practice.
The implementation of a computational fluid dynamics algorithm within the ESP-r system | 1995 | English
This paper describes the implementation of a computational fluid dynamic algorithm within the ESP-r building energy modelling system.
Three computer programs have been developed for use in assessing solar heat gain through windows in buildings. SUNSPEC calculates the direct beam and diffuse sky solar spectral and broadband irradiances incident on an arbitrarily oriented plane, f
Visualize-ITTM is a visual data analysis tool kit. RLW Analytics has developed a number of specific data visualization tools for the study of the total load and end-use data produced by the DOE 2.1 building simulation package.
In this paper a new procedure of determining the thermal resistance and the thermal capacity of multilayer walls is described. Its feature is the simulation of the thermal behaviour of the wall with subsequent parameter identification.
Previous work has shown that for saturated air/water vapour mixtures, water vapour transfer in cavities can cause very large increases in net energy transfer due to its effect on natural convection.
Simultaneous modelling of heat and moisture transfer and air-conditioning system in buildings | 1995 | English
A simplified building heat and moisture transfer model has been developed and integrated with relevant air-conditioning system component models for simultaneous simulation of heat and moisture transfer at the building envelope, the indoor air-zone
This paper introduces a new approach towards the assessment of thermal building performance. As a specific aspect of overall building performance, thermal comfort performance is examined in detail. Two issues have been addressed.
This paper gives an overview and examples of varíous approaches to system simulation in buildings. Advantages and disadvantages of the different methods with respect to problems commonly encountered in building performance evaluation are described
