THERM 2.0: a building component model for seady-satate two-dimensional heat transfer | 1999 | English
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.
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.
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
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.
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.
Based on K- two equation turbulence model, we used PHOENICS 1.4 and numerically simulated air distribution and contamination field under different conditions in a vector- flow clean room.
A major goal in computer-aided design research has been the development of integrated design for convenient generation and evaluation of evolving designs.

Selection and control of HVAC systems for optimal life-cycle efficiency using simulation techniques | 1999 | English
Design of air conditioning systems for efficient and effective part-load operation poses a considerable challenge, but one which is frequently not appreciated by the designer tied to traditional design practices.
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.
This paper decribes a research project to compare, using simulation, the summertime comfort and energy use of naturally ventilated and mixed-mode (limited cooling) UK office buildings.
The LESCOM program using the Response Factor Method developed by the authors was applied to the direct gain system and calculation of fluctuations in room temperature.
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.
