Improving simulation accuracy through the use of short-term electrical end-use monitoring | 1999 | English
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.
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.
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
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.
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.
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.
Many of the popular building energy simulation programs around the world are reaching maturity– some use simulation methods (and even code) that originated in the 1960s. For more than two decades, the U. S.
One central idea of building simulation is to visualize calculated datavalues embedded in an in herently three dimensional building shape.
The high thermal insulation of housing construction has been spreading all over Japan, for the improvement of indoor environment and the efficiency of energy consumption.
Energy Conservation Buildings are very effective for restraint of global warming, because they can reduce CO2 emissions in building operation, which account for 70% of Life Cycle emissions.
Fault detection and diagnosis on HVAC variable air volume system using artificial neural networks | 1999 | English
Abrupt faults on HVAC components as blocked dampers or broken fan belt can be successfully detected by methods based on logic rules.
A building simulation program has been developed and a model of a standard Swedish single family house has been built up. The model uses an explicit finite-difference method to calculate the temperatures of the next time step.
