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
A patented, low energy, fresh air fan convector has been developed by a HVAC equipmentmanufacturer in conjunction with a leading controls supplier and a local University.
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.
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.
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.
Air exchange rates of ten residential buildings were measured according to ASTM-E741-83 using SF6 as a decaying tracer.
With a diameter of 320m, and a height of 50m the Millennium Dome is one of the World's largest enclosed spaces, probably the largest among those intended for public use.
This study is part of an investigation of the decontamination capabilities of indoor plants.Three internationally used species, Howea forsteriana Becc. (Kentia Palm), Dracaenaderemensis Eng.
A test room was used to evaluate the impact of airflow parameters on the effectiveness of an air cleaning system. The room’s dimensions were nominally 11.2 m x 5.7 m x 2.7 m.
Measurement of ventilation, air distribution and inter-zonal air flows in a 4-storey historic building using a passive tracer gas technique. | 1999 | English
Air temperature, air humidity and ventilation has been measured in a Swedish baroque castle. Results are presented for a measurement campaign comprising four periods under varying climatic conditions.
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.
