Design of air conditioning systems for efficient life-cycle operation using the ZEBRA software package | 1997 | English
Integration of computer based modelling and an inter-disciplinary based approach to building design in post-graduate education | 1997 | English
Computer based design aids have much potential to improve the productivity of the design process and provide more confidence in the performance of a building.
Reliable sky luminance models are considered to be conditio sine qua non for accurate computational simulation of daylight distribution in architectural spaces. Toward this end, the paper compares six sky models specifically with regard to their a
Examination of the concept of using 'typical-week' weather data for simulation of annualized energy use in buildings | 1997 | English
This paper investigates the feasibility of using short segments of weather data to simulate annual energy use in buildings.
A numerical and experimental study is performed to analyze the influence of natural convection on heat transfer in a composite system comprising a porous material heated from below and an air space situated above this.
Many building simulation computer programs, originally developed on mainframe computers for research purposes, can now run on the powerful workstation and personal computers that are available to most architectural and engineering firms.
A new integrated simulation system for the building services design and facilities management purposes is being developed by Insinööritoimisto Olof Granlund Oy.
BASESIMP: a residential-foundation heat-loss algorithm for incorporating into whole-building energy-analysis programs | 1997 | English
Heat losses from foundations are poorly considered in many whole-building energy programs which are used to model houses.
COMIS 3.0: a new simulation environment for multizone air flow and pollutant transport modelling | 1997 | English
COMIS 3.0 is a new simulation environment developed in the framework of IEA/ECB Annex 23. To our knowledge this is the first time that one of the Annexes of IEA/ECB produces as its main result a validated software not only designed for research la
A major barrier to using energy simulation tools during the design process of a building has been the difficulty of using the available programs.
The design of monitoring system for distnbuted energy and heat supply is presented in the paper.
In this paper, a new method of direct run - time coupling between building energy simulation and global illuminance simulation is outlined and discussed.
If a map of a city is encoded as a Digital Elevation Model, it becomes amenable to image-processing software, such as the public-domain NIH Image application.
Application of simulation in design and operation of refurbished buildings and heating systems | 1997 | English
This paper gives an introduction into the simulation of the thermic behaviour of a modernized building including the calculation of both single and two pipe heating by a new TYPE57 for simulation of heating pipe systems within the program TRNSYS.
Computation of sound propagation in enclosed spaces is needed for a variety of purposes such as noise exposure in industrial spaces, acoustic privacy conditions in open-plan office settings, and speech intelligibility in auditoriums.
This paper describes the simulation of electric storage heaters and their controls. A method for modelling manual control, inferred from transformer readings, is described.
This paper presents the theoretical modelling work of an elementary urban units (street), thermal behaviour.
A simulation software focused on HVAC energy consumption in large supermarkets, called Clim Top, has been recently developed in France.
A new method aimed at the selection of the best reduction technique for each given invariant linear system, such as those obtained when modelling the thermal behaviour of building envelopes, is presented here.
Numerical and experimetal assessment of a flow field in a ventilated industrial hall | 1997 | English
The paper presents the results from a numerical and experimental investigation of the velocity distribution in a ventilated industrial hall in the nuclear power plant in Bulgaria.
