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
Up to now, within the framework of validation of the global building energy simulation software programme CLIM2000, we have not focused on analytical verification.
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.
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.
Towards the building as power plant: computacional analysis of building enrgy self-sustenance | 1999 | English
In recent years there have been a number of research and development initiatives directed at integrated energy generation systems which can meet the energy requirements of a building substantially or even completely on-site.
We present in this paper the essential aspects of the S2 system. This is the internet realization of SEMPER: An active, multi-domain, space-based, object oriented design environment for integrated building performance modeling.
The successful application of moisture simulation models to building envelopes requires accurate values of material transport properties. Unfortunately, although the presently-available database is reasonably voluminous, much of the informatio
Thermal evaluation of strategies for an adequate housing in arid zones and their impact on energy saving | 1999 | English
Located in an extreme arid natural environment, the city of Mexicali has confronted maximum temperatures of 54C during summertime.
The applicability of ray-tracing based simulation tools to predict sound pressure levels and reverberation times in 'coupled spaces' | 1999 | English
Nowadays architects commonly use the ‘coupled space concept’. Examples are mezzanines, half-open office spaces and exhibition rooms.
Recent developments in photovoltaic components, small-scale combined heat and power systems and ducted wind turbines have opened up the possibility for an embedded generation approach to building design.
Thermal comfort and pollutant transport prediction in the object oriented environment spark | 1999 | English
A coarse-grid zonal model of room air convection is formulated and written with the SPARK object- oriented simulation environment.
Building dynamic simulation has been available to building design engineers for some time.
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
Construction and operation of buildings is internationally a major cause of resource depletion and environmental pollution.
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.
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 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
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.
