Rational operation of a thermal storage tank with load prediction scheme by arx model approach | 1997 | English
The control strategy of the thermal storage HVAC system gives a large effect to the storage efficiency which dominates the tank volume to a great extent. Authors introduce how the temperature distribution of the tank varies and gives a considerabl
This paper describes a recent extension to the ESPr system concerned with the simulation of facade and roof-integrated photovoltaic modules.
Numerical simulation of air flows: an essential tool of comfort optimization of modern buildings and HVAC systems | 1997 | English
The paper deals with the CFD (computational fluid dynamics) application to the comfort optimization of some complex architectural projects in which the physical interaction effects between the building and its environment affect strongly the build
The XCEED™ software tool allows engineers to create textual, mathematical and graphical descriptions of compressed air systems including, but not limited to, compressors, filters, dryers, storage vessels, cooling equipment, piping and utilization
Validation of a building thermal model in Clim2000 simulation software using full-scale experimental data, sensitivity analysis and uncertainty analysis | 1997 | English
Within the framework of full-scale experimental validation of the global building energy simulation software programme CLIM2000, an experimentation has been carried out in a 100 m² real house from Oct 95 to May 96.
Predicting natural ventilation air velocity using deterministic and nom-deterministic methodologies | 1997 | English
An extensive experimental program on single sided natural ventilation was carried out within the frame of PASCOOL EC research project.
A case study is used to introduce a two-step thermal demand calculation for buildings in order to take thermal bridges into consideration.
Training new users of simulation programs typically focuses on a single tool–specific techniques for interacting with, creating models, and assessing performance.
New generation of software? modeling of energy demands for residential ventilation with HTML interface | 1997 | English
The paper presents an interactive on-line package for calculation of energy and cost demands for residential infiltration and ventilation, with input and output data entry through a web browser. This is a unique tool.
Passport Plus is a new design tool for building thermal analysis which was developed within the European research project PASCOOL of the European Commission.
Design of air conditioning systems for efficient life-cycle operation using the ZEBRA software package | 1997 | English
Life-cycle design of air conditioning systems requires that plant should be capable of maintaining zone comfort conditions within specified limits, while minimising capital and operating costs.
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.
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.
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.
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
