摘要:

A proposed smoke ventilation system, in case of fire, is investigated for its effectiveness by computational fluid dynamics. Two building fire situations are modelled and the smoke concentrations throughout the building are predicted. The specified criterion is that visibility at eye height remains sufficient for the building to be evacuated. The predictions show that the proposed system is effective and that the higher of two modelled fan capacities is required.

摘要:

The Typical Meteorological Years (TMY) for Hong Kong is generated by using the weather data recorded by the Royal Observatory of Hong Kong from year 1979 to 1988. Data used in the analysis included the hourly dry bulb temperature, dew point temperature, wind velocity, total global solar radiation, etc. The monthly Cumulative Distribution Function (CDF) of those selected data was compared with the long term values of the CDF for each month of a year. The persistence structure was studied by Finkelstein-Schafer (FS) statistics. The deviations of CDF of the mean dry bulb temperature and total global solar radiation was examined. The weather data of the chosen typical year is compiled in TMY format. With this TMY, the building energy loads in a higher education institute in Hong Kong were simulated using the energy simulation program BLAST. The results were compared with the building energy loads of all the years from 1979 to 1988.

摘要:

The analysis and evaluation of light-shelves design are complex and involve numerous parameters. These features require the development of various methods and tools to help the designer analyse and evaluate the many possible configurations. Conventional statistical tools for generating performance algorithms are not easily adaptable to this problem due to the very large number of independent design variables involved in the equation. In this article Neural Networks (NNs) are introduced as a promising computation method for the analysis and evaluation of daylight illumination due to the light shelf. NNs are shown to have powerful capabilities for generalising a solution by learning a few examples, by associative and adaptive processing, and tolerating the fault inherited from incomplete data.

摘要:

There are numerous ways of presenting the relationship of apparent solar time, day of year, solar azimuth angle, solar altitude for a defined latitude, as observed from a fixed point contained within a horizontal plane at that latitude.
