This paper discusses a multi-year (MY) approach to building energy simulation and presents a pilot study in Hong Kong that investigates long-term building energy performance using MY weather data. Building energy simulations in the pilot study wer
Collaborative building engineering is a team effort in which many elements have to be combined into a unified structure. The aims of the architect, the engineer and all the other players have to merge into a seamless design process.
Evaluation of the finite control volume method in simulating thermal fire resistance of building elements | 1997 | English
Application of the finite control volume method on simulating thermal fire resistance of building materials and elements was evaluated. Example was taken on studying the thermal responses of a concrete column under fire.
This paper reports the first results of an ongoing project aimed at generating design information /knowledge for wet central heating (WCH) refurbishment in multi-family houses in Central Europe.
This paper describes the use of daylight coefficients in a computer tool which is based in Monte Carlo backward ray tracing merthod and was developed under the frame of DAYLIGHT- Europe EC Project.
Influence of modeling uncertainties on the simulation of building thermal comfort performance | 1997 | English
In this paper, the parameters in a building thermal simulation model are tracked, which are subject to modeling uncertainty, i.e. uncertainty arising from commonly applied physical assumptions and simplifications.
Moisture permeability data presented as a mathematical function applicable to heat and moisture transport models | 1997 | English
The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process.
CA-SIS software has been developed on PC as a tool for engineering offices in their Heating, Ventilating and Air Conditioning studies.
Energy saving in office buildings: a case study in Rome through the use of DOE-2 and other simulation tools | 1997 | English
A large office building has been the object of a detailed feasibility study in order to select the most effective actions for energy saving in space cooling. Actions concerning the modification of building envelope layout, including materials, sha
This paper briefly reviews recent research into the modelling of complex fenestration systems, before presenting some results obtained by the use of a new (developing) simulation model, utilising Monte Carlo Methods and Geometric Optics (ray traci
A controller for heating systems is normally equipped with many facilities to make it flexible and the heating system more cost-efficient. This results in a number of input parameters to be given by the user.
Combined conduction-convection-radiation heat transfer in concrete block walls with one or two cavities is simulated using the CFD code “FIDAP”.
Methodology for modelling/simulation of an office building equipped with an air-condicioning system | 1997 | English
This article presents a study of a building-equipment coupled system performed at the Gaz de France R & D Division. The commercial building under study is equipped with an air-conditioning installation which includes a gas-fired dual-seJVice a
Calibration of hourly energy simulations using hourly monitored data and monthly utility records for two case study buildings | 1997 | English
This paper presents a calibration methodology using only two to four weeks of hourly monitored and monthly utility records.
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.
A hybrid monitoring-modeling procedure for analyzing the performance of large central chilling plants | 1997 | English
This paper presents a methodology to effectively model the performance of central chilled water plants in campus or multi-building complexes where detailed modeling of every building served by the plant is out of the question, usually due to budge
During the academic year 95-96 an NMF based model library has been developed by the IDA group.
A systematic method for hygrothermal analysis of building constructions using computer models | 1997 | English
The design of a naturally ventilated atrium was assessed using both wind tunnel and CFD methods to appraise and modify the response of the system to wind forces.
