Calibration of hourly energy simulations using hourly monitored data and monthly utility records for two case study buildings | 1997 | English
Dynamic link of light- and thermal simulation: on the way to integrated planning tools | 1997 | English
A method to evaluate the energy demand for lighting on an hourly basis is presented. The method is based on a raytracer and a dynamic modelling of the sky’s luminance distribution.
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.
A case study is used to introduce a two-step thermal demand calculation for buildings in order to take thermal bridges into consideration.
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.
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.
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.
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
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.
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.
The design of monitoring system for distnbuted energy and heat supply is presented in the paper.
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.
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.
In this paper, a new method of direct run - time coupling between building energy simulation and global illuminance simulation is outlined and discussed.
