The research on provision of computational support for building performance analysis has traditionally concentrated on the building design phase. However, computational modeling can also effectively apply to the building operation phase.
Linking the comis multi-zone airflow model with the energyplus building energy simulation program | 1999 | English
This paper describes an effort to link the COMIS 3.0 multi-zone airflow model with the EnergyPlus building energy simulation program.
Numerical analysis on the production of cool exergy by making use of heat capacity of building envelopes | 1999 | English
This paper describes a method to calculate cool and warm exergies stored by building envelopes and the result of a case study in terms of passive cooling strategy using the building envelope heat capacity.
Research on calculation method of thermal design load in radiant heating and coolind systems | 1999 | English
A new calculation method is proposed for designing space radiant heating/cooling systems by improving conventional methods of steady and unsteady heat transfer calculation theory which has usually been used for designing of buried pipe floor heati
Studyind thermal performance of split-type air-conditioners at building re-entrant via computer simulation | 1999 | English
The use of split-type air-conditioners in new apartment buildings becomes popular in Hong Kong. One requirement for their effective use is satisfactory heat rejection at the outdoor condensing units.
The treatment of convective heat transfer at internal building surfaces has a significant impact on the simulation of heat and air flow.
The optimization of the cogeneration systems (CGS) with the gas engine generator is studied by using the Hamiltonian algorithm (HA).
Simulation of daylight performance of buildings by the daylight source model based on geostational meteorological satellite images | 1999 | English
This paper introduces a method to simulate the day-light performance of buildings using geostational me- teorological satellite images.
Numerical analysis of annual exergy consumption for daylighting, electric-ligthing, and space heating/cooling system | 1999 | English
The purpose of this study is to show explicitly a series of exergy input, output, and consumption for daylighting, electric-lighting, and space heating/cooling system and hence to reveal how daylighting system consumes solar exergy and how electri
RARX algorithm based model development and application to real time data for on-line fault detection in Vav Ahu Units | 1999 | English
Assimilation of cost-effective Fault Detection and Diagnosis (FDD) technique in building management sys- tem can save enormous amount of energy and material.
When some faults take place in a thermal storage HVAC system, changing pattern of the temperature profiles of the thermal storage tank is useful to infer where some faults exist.
Internal melt ice-on-coil tank with built-in horizontal tubes is a kind of ice tank used widely. Its discharge process is effected greatly by density different between ice and water.
A reduction in the emissions arising from urban activities demands a combination of energy efficiency measures and a move away from fossil fuel sources.
The purpose of this study is to develop the technique that mixing energy loss is predicted at the time of the air conditioning system design by the simulation.
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.
