In that study, induced ventilation is experimentally explored in a small well-insulated manufactured home, located in the northern edge of the Negev desert in Israel. Temperature monitoring was performed inside and outside the building in summer along with velocity measurements inside the building. The results show that with induced ventilation the air temperature inside the home is like the ambient temperature, whereas, when no openings, the temperature inside the manufactured home is higher than the ambient.
It is not easy to provide simultaneously thermal comfort, proper air quality, efficient energy consumption to building occupants. In this paper an alternative methodology of real-time determination of optimal indoor air condition for HVAC system to achieve those 3 requirements is presented. A 24 hours operating HVAC system of a single-story building was chosen as a case study.The experiment results obtained with the proposed methodology were better than those from a conventional approach.
The use of a combined methodology of wind tunnel experiments and CFD simulations in order to study the potential of using active stack to enhance natural ventilation in residential apartments in Singapore is demonstrated in this paper. Comparison between the results obtained from the experiments and those from the simulations has been made.
This paper presents an extensive field survey conducted in residential naturally ventilated buildings in Indonesia. The data gathered has been analyzed and revealed that the Predicted Mean Vote equation predicted a warmer thermal perception compared to what people really felt. Under hot and humid tropical climate, people in free-running buildings had a preference for cooler environment and for higher wind speed.
For that study, 12 office rooms of a "Solar Optimised Building" in Germany have been monitored. The data have been evaluated by a new method for analysis that deals with short and long term measurements and with building simulation. A comparison between monitored data and simulation of a building with passive cooling by night ventilation is made on a long period.
In this paper the authors present the results of the European AIRLESS programme whose aim was to identify the pollution sources in air-handling units, and then avoid or eliminate this pollution. The authors propose several energy efficient ways to provide good indoor air and efficient indoor environment conditioning.
For that study , three german buildings with double facades have been monitored for at least one year in order to evaluate their energetic performance. The first building had no air conditioning facilities, the second one had cooling equipment without mechanical ventilation, and the third one had cooling equipment combined with mechanical ventilation.
The method of exposure prediction using the scales of accessibility of supplied air (ASA) and the scales of accessibility of contaminant source (ACS) is presented in this paper. The spreading performance of supplied air and indoor pollutants can be figured out by CFD simulation and then used for the prediction of contaminant dispersion. For the validation of the model, a traver gas measurement was conducted.
The aim of the study is to evaluate the possibility of ensuring an indoor climate within an acceptable range thanks to the use of large exposed massive wood surfaces. The description of the experimental study performed in four occupied flats of a multi-storey residential building in Sweden is made in this paper along .The analysis of the in-situ recordings is presented too.
