Analysis and improvement of stack effect for the staircase of apartments in fire accidents in Taiwan

Fires in buildings account for 60% of fires in Taiwan. Since establishment of the National Fire Agency in  1995, many fire codes have been promulgated resulting in a gradual decline in the number of casualties of fire. However, for old apartments in urban areas, although regulations aimed at improving fire-prevention refuge facilities and fire-fighting equipment of existing building have been announced, they cannot be implemented efficiently due to the lack of public acceptance. This investigation has found that hundreds of thousands people live in such buildings.

Effect of Intermittent Operation of Ventilation System on Indoor Air Quality in Apartments

This study analyzed the effect of intermittent operation of ventilation system on changes of indoor air pollutants' levels through field measurements. The changes of indoor air pollutants' levels, such as, CO2, PM10, TVOCs, and HCHO were monitored during 24 hours at each ventilation condition. One group was the operation time: 2 hours, 8hours, and 24 hours. The other group was the changes of start time of ventilation, before noon, after noon, and night, while the ventilation was operated only two hours.

Effect of Party Wall Permeability on Estimations of Infiltration from Air Leakage

The importance of reducing adventitious infiltration in order to save energy is highlighted by the relevant building standards of many countries.  This operational infiltration is often inferred via the measurement of the air leakage rate at a pressure differential of 50 Pascals.  Some building codes, such as the UK’s Standard Assessment Procedure, assume a simple relationship between the air leakage rate and mean infiltration rate during the heating season, the so-called leakage-infiltration ratio, which is scaled to account for the physical and environmental properties of a dwelling.  The

A study of window location and furniture layout to maximise the cooling effect for an urban Taiwanese apartment by night ventilation.

The year-round climate of Taiwan is warm and humid. Apart from the hottest months in summer, there are four months suitable for nocturnal ventilation to acquire indoor cooling. The urban Taiwanese apartments are small due to the limited usable land.
