Thermal comfort and pollutant transport prediction in the object oriented environment spark | 1999 | English
Building dynamic simulation has been available to building design engineers for some time.
Construction and operation of buildings is internationally a major cause of resource depletion and environmental pollution.
This paper referrer to the existence of the variety modes and the 'chaos' in building ventilation system, and provides some instances of such varieties and the chaos in forced ceiling chamber smoke exhaust system in building fire. The numer
Thermal analysis of 3-dimensional heat brigdes included in steel framed houses: method of making models and analysis examples | 1999 | English
In this report, recently developed computer program named TB3D/FDM(Thermal Bridge Computa- tion by 2- or 3-Dimensional Finite Difference Method) is introduced.
The control of the thermal environment of perimeter spaces in buildings to prevent cold drafts | 1999 | English
This paper is focused on the evaluation of simulation system using the experiment result and the con- figuration of peri-counter which is the part of counter unit setting at bottom of window side with heat panel to avoid the influence of cold draf
UMIDUS: A PC program for the prediction of heat and moisture transfer in porous buildings elements | 1999 | English
This paper presents the Umidus program which has been developed to model coupled heat and moisture transfer within porous media, in order to analyze higrothemal performance of building elements when subjected to any kind of climate conditions. Bo
The use of simulation software to evaluate the thermal performance of buildings in Brazil | 1999 | English
The traditional methods for the evaluation of the thermal performance of buildings are appropriate to winter conditions and are often used in standards that regulate energy consumption.
Thermal storage with concrete slab of pressurized plenum in underfloor air distribution system | 1999 | English
In calculating the heat flows around the floor plenum of underfloor air distribution system, the convective heat transfer coefficient is an influential factor, but it is not clearly known which value should be taken.
The application of computer simulation techniques to the design and preservation of a national monument | 1999 | English
The paper outlines a two-year research program where Radiance was used in the conversion of Empress Place, a national monument in Singapore, into an Asian Civilisation Museum.
The simulation of photovoltaic power generation and wind power generation on the hydrid electricity supply system of a building | 1999 | English
Solar energy and wind energy are one of renewable energies, and they are inexhaustible energy source which are available anywhere.
Thermal enviroment of the house with a moisture-absorbent typt dehumidifier in summer | 1999 | English
If an insulated and airtight house is cooled by passive ventilation using buoyant convection, the indoor air temperature can be kept lower than the outdoor air temperature, but there is a tendency for the indoor humidity to remain at a high level.
The analysis of the convenctive-conductive heat transfer in the building constructions | 1999 | English
The numerical model for the analysis of the combined convective-conductive heat transfer in the building components has been developed.
The effects of indoor conditions on the reduction of energy consumption in commercial buildings in rio de Janeiro | 1999 | English
Most of the Brazilian population is concentrated in the shore region in cities like Rio de Janeiro.
There are two kind of supply fan rotation speed control methods, one is the static pressure control method, the other is the float pressure control method. Simulation shows that they have different working point along the whole year.
Based on the thermal and airflow network model with simple but perfect generic formulations and stable solving methods, a computer program NETS for the practical simulation of coupled building heat, gas and air transfer system has been deve
An evaluation method for life cycle energy (LCE) and CO2 (LCCO2) of houses by the system dynamics (SD), a method for understanding how all the objects in a system interact with one another, was presented.
The diffusion process of kitchen gas exhausted to the outdoor air surrounding a multi-unit housing facility | 1999 | English
This paper examines the process by which the kitchen exhaust from a dwelling unit diffuses throughout the other dwelling units in a seven-story housing facility.
Up to now, within the framework of validation of the global building energy simulation software programme CLIM2000, we have not focused on analytical verification.
THERM 2.0: a building component model for seady-satate two-dimensional heat transfer | 1999 | English
THERM 2.0 is a state-of-the-art software program, available without cost, that uses the finite-element method to model steady-state, two-dimensional heat- transfer problems.
