LoginOne sixth of the total energy consumed in Taiwan is for building operation, mainly for summer cooling. The energy consumed for summer cooling can be greatly reduced if naturalventilation can be exerted in Taiwanese urban apartments.

The combined wind and stack effects on the induced air flow volume in a two-story building through the investigation of wind velocity, solar insulation, and roof design. | 1999 | English
Air handling units do not always function as planned: airflow rates are often larger than required, the recirculation rate is not at its set-point value and parasitic shortcuts sometimes decrease dramatically the ventilation efficiency.
Performance of an advanced air conditioning system during extreme weather conditions in a generator plant. | 1999 | English
This technical note considers the performance evaluation of an advanced air-conditioningsystem in a plant manufacturing electrical generators.
Computer simulation of building airtightness measurements shows the effect of changes inpressure distribution across the building envelope due to wind force and temperature differenceon measurement accuracy.
Air exchange rates of ten residential buildings were measured according to ASTM-E741-83 using SF6 as a decaying tracer.
This field study was organised to track differential pressure relationships in critical care units of a metropolitan hospital. Maintaining design pressure balances is essential to control risk of airborne disease transmission within these units.
Individual air distribution control panel on partition panel at personal task area. | 1999 | English
A general trend in intelligent buildings is the decentralization of environmental controlsystems. Decentralized environmental control systems have many advantages over centralizedsystems.
Emissions from dust collected in air filters have been investigated using in situ and chambermeasurements.
The influence of an architectural design alternative (transoms) on indoor air environment in conventional kitchens in Taiwan. | 1999 | English
This study investigates indoor air environment via the flow fields, temperature fields and air contaminants (carbon monoxide) distributions in conventional residential kitchens, and looks for effective methods to solve those problems through natur
Air cleaners are unitary devices that contain filtration media and fans. They are marketed for cleaning air in rooms.
The effect of loading dust type on the filtration efficiency of electrostatically-charged filters. | 1999 | English
Ventilation filters composed of electrostatically-charged fibers, also referred to as electret filters,are know to have the potential to decrease in filtration efficiency with use.
Pressurisation tests of selected apartments as a base for analysis of natural ventilation in multifamily building. | 1999 | English
The paper presents a study on application of pressurisation tests of selected apartments as a base for analysis of natural ventilation in multi-family building. The analysis has been performed for 5-floor building constructed in late sixties.
Air recirculation in the new office and laboratory building of the Norwegian Institute for AirResearch was discovered and characterised from a leaking sulphur hexafluoride cylinderstored in the garage.
Particle concentrations in an air conditioned office building with normal and high efficiency filtration. | 1999 | English
Indoor and outdoor particle concentrations and ventilation rates were measured versus time ina large office building without tobacco smoking. Periodically, high efficiency filters replacedthe normal filters in air handling systems.
The design of natural ventilation systems - the configuration and sizing of system components - assumes one of two generic forms: the nasty form based on thermal comfort criteria or the nice form based on specified airflow rates.
Airborne fungi in indoor air has the possibility to cause the air pollution problems of the fungally infection syndrome and the allergy syndrome, etc. in residence environments.
The cabin air filter performance is of prime importance for the air quality in vehicles. New clean filters were tested but also filters loaded with actual traffic contaminants. Both laboratory and field measurements were included in the study.
A measurement of the thermal performance and air distribution of indoor sports ground using swirling flow type natural ventilation system. | 1999 | English
This report describe the thermal performance and air distribution of a Kumamoto prefecturalindoor sports ground in Japan.
A field experiment on indoor consistency distribution of combustion gas by ventilation performance of range hood. | 1999 | English
In apartments of Korea, exhaust-only hood system is commonly installed for kitchen ventilation.
The role of indoor plants as a source of microorganisms was studied in six office rooms.Concentrations of microorganisms (both fungi and actinomycetes) were determined fromindoor air and settled dust before the plants were placed in the office roo
