The aim of the study was to investigate the association between ventilation and the worker’s nonspecific building-related symptoms (BRS) in one office. The study office took place in the sixth floor of one semiconductor company with a floor area of 1452 m

An individually controlled system (ICS) at room air temperatures of 20, 22 and 26°C has been tested by forty-eight subjects . Human response to a reference condition without the ICS at a room air temperature of 22°C was also collected. The results reveal

The aim of this study is to investigate the distribution of different body parts’ surface temperatures in the space served by displacement ventilation (DV) system. The experiment was conducted in a Field Environmental Chamber in the tropics. The manikin

This paper provides on the one hand data for the improvement of indoor environment in existing high-rise residential buildings in hot summer and cold winter region of China, and on the other hand helps for the designing of HVAC system of such buildings.

For that study an aircraft cabin with realistic pollution sources was built inside a climate chamber to determine the extent to which passengers’ perception of cabin air quality is affected by air temperature. The temperature inside the cabin was set at

This paper, after a general presentation of what indoor air quality is, discusses the development of new methods for the improvements of IAQ in maintaining or decreasing ventilation and energy use.

This paper investigates the effectiveness of a Purging System in a high-rise office building in Singapore with the aim of improving indoor air quality. The study initially adopts a continuous monitoring concept to investigate the impact of a daily purging operation on pollutant concentration levels at the low, middle and high floors of the office building. Pollutants investigated include formaldehyde, carbon dioxide, carbon monoxide and total volatile organic compounds (TVOC).

It is very important to estimate the stack pressure difference across exterior walls for understanding the energy impacts of infiltration and ventilation in high-rise buildings, because stack pressure is likely to significantly affect energy load and is sustained over a long period. This paper presents a simple prediction strategy for estimating the pressure distribution in high-rise residential buildings, using key parameters that affect the magnitude and distribution of stack pressure.

This paper presents simulation results of the performance of ventilation systems with self-regulating inlets in different types of typical Flemish dwellings. Normal free air inlet vents have one major disadvantage: the complete dependence on the variable outside weather conditions (wind and temperature). The use of selfregulating inlets should minimize this impact, optimize the indoor comfort (no draught) and reduce the waste of energy by ventilation.

This study considers the link between tertiary buildings design and equipments known as natural and hybrid ventilation or cooling. It focuses on the case of cross ventilated buildings and the envelope choices able to ensure comfort along with energy savings. This link is studied by simulating with TRNSYS various cross ventilation systems: by night, day or both. These are applied to typical situations as individual office, open-plan office, or meeting rooms. Studied rooms are chosen south oriented and subjected to medium internal gains.
