Numerical study of a naturally cross-ventilated building

Energy and Buildings, 2010
Abstract This paper deals with the numerical three-dimensional prediction of the induced flow patterns around and inside a building, which is cross-ventilated in a natural way. The air change rate is controlled by two opposite openings on the building envelope, as a function of wind velocity and its incidence angle. The numerical methodology is based

Changes in Low Profile Cross Ventilated Dairy Facilities

2009 Reno, Nevada, June 21 - June 24, 2009, 2009
The performance of an evaporative cooling system was evaluated in the High Plains region on a low profile cross ventilated dairy facility housing 4,200 lactating cows. The evaporative pad was 3 m (10 ft) tall and approximately 426 m (1,400 ft) long. Temperature and humidity data were collected every 15 minutes at three locations each baffles in the ...

Natural cross ventilation in buildings on Mediterranean coastal zones

Energy and Buildings, 2014
Abstract Natural ventilation of buildings is a common way to improve indoor air quality, thermal comfort in summer and reduce energy consumption due to air conditioning. However, efficiency of such a system is highly dependent on climatic conditions. This paper investigates the use of thermal breezes, characterized by moderate speeds and well-defined

Cross-ventilation of a room in a courtyard building

Energy and Buildings, 2016
Abstract The influence of courtyard height on the cross-ventilation of a room abating a courtyard building is addressed in this work. While the cross-ventilation performance of isolated buildings has been thoroughly documented in the literature, the phenomenon is still not tackled in the context of a courtyard building, both in isolated as well as ...

CFD modelling of unsteady cross ventilation flows using LES

Journal of Wind Engineering and Industrial Aerodynamics, 2008
Traditional methods using steady-state simulations with RANS models may predict adequate flow characteristics of cross ventilation, provided the selected turbulence model, boundary conditions and level of mesh resolution are appropriate. However, these methods are less satisfactory if we are more interested in the statistical description of fluctuating

Windows design for maximum cross-ventilation in buildings

Advances in Building Energy Research, 2016
ABSTRACTComputational Fluid Dynamics numerical analysis is performed to investigate the ventilation performance and the internal thermal environment of naturally ventilated buildings. Several alternative scenarios are generated by varying the size of openings with different configurations of orientation and solar shading.

Review of Cross-Ventilation Research Papers - from the Working Group for Natural Ventilation and Cross-Ventilation of the Architectural Institute of Japan

International Journal of Ventilation, 2009
AbstractA working group for natural ventilation and cross-ventilation at the Architectural Institute of Japan (AIJ) was established in 2005 by researchers and designers with an interest in this topic. One of the tasks of the working group is to review and classify related research papers.

Air Emissions from a Low-Profile Cross-Ventilated Dairy Barn

International Symposium on Air Quality and Waste Management for Agriculture, 16-19 September 2007, Broomfield, Colorado, 2007
Low-profile cross-ventilated (LPCV) freestall buildings are another option for dairy cattle housing. These facilities allow producers to have greater control over the cow’s environment during all seasons of the year. These buildings are placed closer to the parlor, reducing time cows are away from feed and water, resulting in a smaller overall site ...

Measurement of cross-ventilation rate in urban multi-zone dwellings

Building and Environment, 2019
Abstract Cross ventilation can effectively improve air quality with larger ventilation rate than single-sided natural ventilation. The measurement of ventilation rate is critical for research on indoor environmental maintenance and air quality control.

Full-scale measurements and wind tunnel tests on cross-ventilation

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract This paper describes the full-scale measurements and the wind tunnel model tests on cross-ventilation induced by the natural wind and the similarity between them. The full-scale measurements were conducted in a group of apartment houses under the condition that the direction of the approaching wind to the objective site was almost constant ...
