Measurements of indoor air pollutants covering the concentrations of CO2, CO, TVOC’s, PM2.5, and PM10 were performed in 50 residences in Athens.
There is a wide range of factors that influence natural ventilation. The uncertainties arising from theunpredictable nature of wind lead to the need to account for periods of time when winds are unable to provide indoor summer comfort.
Infiltration of outdoor air in two newly constructed high rise residential buildings | 2006 | English
The transmission of SARS in high rise residential buildings in Hong Kong has highlighted the importance of indoor environmental quality. One of the important parameters that requires investigation is natural ventilation.
Levels of Indoor Airborne Microbes Associated with Ventilation Efficiency in Naturally-Ventilated Residences | 2006 | English
Indoor microbial exposure has been implicated in various adverse health effects.
Measurement and Prediction of Aerodynamic Stability of an Axial-Flow Ventilation Fan near the Stall Condition | 2007 | English
This paper attempts to look at the unsteady flow pressure on the blade tip in order to quantify the inception of instability of an axial-flow ventilation fan.
Minimum Outdoor Air Supply for Radon in High Rise Residential Buildings - Natural Ventilation v Air-Conditioning Unit | 2007 | English
Natural ventilation, as a medium for air exchange between the indoor and outdoor environment, is known for its functions of providing outdoor ‘fresh’ air and removing indoor air pollutants.
Mixing Property and the Heat Exhaust Effect under Cross Ventilation in a Full-Scale Experimental Model | 2006 | English
Cross ventilation is one of the most important techniques for achieving energy conservation and for
Numerical simulations and computational fluid dynamics can be usefully integrated with architecturalmodelling to provide designers with a powerful single CFD based architectural modelling and designframework.
Natural, Wind-Forced Ventilation caused by Turbulence in a Room with a Single Opening | 2006 | English
Even if there is only one opening within a room and there is no temperature difference between the inside outside, the room will be ventilated by the external natural wind.
Passive Tracer Gas Measurement of the Long Term Variation of Ventilation in Three Swedish Dwellings | 2006 | English
The objective of this study is to investigate how measured ventilation rates in dwellings vary over the heating season in a Nordic climate.
Underfloor air distribution (UFAD) is a new method of supplying heated or cooled air throughout a building. Reported advantages of UFAD include energy savings and improved indoor air quality (IAQ).
Thermal mass, including the building envelope, the interior partition, the furnishing, or even the air inside building, is defined as the mass that can store thermal energy (heat or cooling energy).
This paper presents results of CFD simulations of flow around and through a cubic building with symmetric openings on two opposite sides.
In this paper experimental results are used to verify and validate a computational fluid dynamics (CFD) model based on a commercial package. The validation is used to ensure that the CFD model is able to simulate stratum ventilation.
Variable Air Volume-Flow Systems - A Possible Way to Reduce Energy Use in the Swedish Dairy Industry | 2007 | English
Growing concern about negative effects on the environment and increasing energy prices stress theimportance of energy efficiency.
Macroscopic methods of building ventilation analysis developed in the past fifty years have proven to be accurate and thus useful for purposes of single- and multi-zone building infiltration, air quality, smoke spread, thermal comfort, and integra
The amount of outdoor air ventilation in buildings is one of the most important determinants of indoor air quality, but many critical questions and misunderstandings exist.
Wind Pressure Coefficients for Different Building Configurations with and without an Adjacent Building | 2006 | English
The design protocol for wind-driven cross ventilation in buildings should include two processes, namely the determination of required ventilation rate to reduce the room temperature and the prediction of the ventilation rate resulting from the arr
Windows and HVAC Operation to Reduce Cooling Requirement by Means of Cross-Ventilation | 2006 | English
Passive cooling by cross-ventilation has been considered to be a key technology for reducing cooling requirements.
