Simulation of daylight performance of buildings by the daylight source model based on geostational meteorological satellite images | 1999 | English
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).
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.
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.
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.
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.
Study into optimized control for air-conditioning system with floor thermal storage | 1999 | English
Air-conditioning systems with floor thermal storage can be used for cutting peak load and utilizing nighttime electric power.
In the present work, human thermal comfort is investigated within the built environment. The analysis is based on two building thermal simulation models.
The paper discusses the development of a computational thermal simulation engine as an object. The simulation engine utilizes Transfer Function (TF) Algorithms where all TF procedures have been implemented.

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 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
