Influence of turbulent wind on air change rates an application with Clim2000 software program | 1999 | English
This research is aimed to improve indoor air quality (IAQ) in the building by using the expert system (ES) based on the artificial intelligence (AI). The diagnosis tool of IAQ and ventilation design tool corresponding to 9 kinds of pollutants were
Evalution of distribution system performance in district heating and cooling system | 1999 | English
In this study, energy simulation program of heat distribution network in a district heating and cooling system was developed. Research on actual condition of heat distribution system of DHC plant was also executed.
Currently used design tools for kitchen design are often complicated, have poor interfaces and limited capabilities to exchange data between different applications.
Addressing the complexity underlying design questions does not appear to be sufficient reason for simulation to be widely deployed in design practice.
Empirical validation of building energy analysis tools by using tests carried out in small cells | 1999 | English
A large empirical validation exercise was recently completed in the framework of International Energy Agency (IEA) Solar Heating And Cooling (SHAC) Task 22 (Building Energy Analysis Tools) (Sub-task A3 « Empirical validation »).
Improving simulation accuracy through the use of short-term electrical end-use monitoring | 1999 | English
Hourly simulation programs such as DOE-2, HAP and BLAST can effectively simulate the performance of HVAC systems in response to seasonal weather patterns.
Development of optimal operation of thermal storage tank and the validation by simulation tool | 1999 | English
Optimization of thermal storage tank operation is one of the major areas for energy conservation in HVAC systems.
Three indices are introduced in order to evaluate cost saving operation of chillers using nighttime low electric power rates for thermal storage systems with water tanks.
Eight mechanically ventilated flow patterns have been conducted in a test chamber. The air age in test chamber is measured with tracer gas technique. A CFD program named as STACH-3 is developed with the transport equation of air age in it.
Data-stream driven distribuited virtual environments: distribuited virtual environments: air quality management district visualization | 1999 | English
The physical space we experience and live in on a daily basis is controlled by the physical laws of nature, which are identified through science.
This paper deals about the presentation of a new software RUNEOLE used to provide weather data in buildings physics. RUNEOLE associates three modules leading to the description, the modelling and the generation of weather data.
In this paper, we describe the characteristics of “Luminous Planner” as a general-purpose lighting design tool, and of “LSR(Lighting Simulation Radiosity)”, which is capable of high-precision lighting simulation by taking space reflection i
Development of an optiml operational planning system using an object-oriented framework for energy supply plants | 1999 | English
An optimal operational planning system with a userfriendly interface using an object-oriented framework is developed for the purpose of determining operational strategies of energy supply plants in a simple and rational manner on personal computer
Estimate for optimum volume of rock bed and air flow rate for an air-based solar heating system | 1999 | English
In this paper, an approach to the optimum volume of rock bed, its charged thermal energy and the optimum air flow rate for an air-based solar heating system in charging mode is presented.
For improving feedback about thermal simulation results from engineers to architects, it is desirable to present them in the three-dimensional context of the building.
The ISE (Intelligent Simulation Environment) concept, developed by CSTB since the early nineties, has been applied to the development of various Simulation Environments (such as IISiBat III for TRNSYS or IISiBat II for COMIS).
The cooling effect caused by long wave radiation between the roof surface and the sky is studied here. The external surfaces may cool down below the dew point of the air and the condensation may form [1]. Typically, the covering of cold roofs has
The convective heat transfer coefficient at an outer ambient wall with a window exposed to natural climate was measured in a room with and without furniture.
Determination method of coefficients and its problems in the simulation of urban air temperature based on one dimensional heat budget model | 1999 | English
It is required that the urban air temperature is estimated on the average and macroscopically for studying the urban thermal environmental problems in summer.
