An integrated computational procedure to predict natural ventilation in buildings.

A computational procedure to predict expected rates of natural ventilation for buildings at the design stage is investigated. This procedure integrates three computational methods, namely one to predict temperature induced pressures, another to compute wind generated pressure distributions around buildings, and the third to analyse the networks of resulting air flows in buildings. Experiments show that these methods are valid. The three methods can be used not only for the prediction of natural ventilation, but also for many other environmental engineering applications, e.g.

The Aylesbury experiment. Comparison of model and full-scale tests.

Describes experiments carried out by the Danish Maritime Institute using data from the Aylesbury experiments of the UK Building Research Establishment. The simulation of the standard rural terrain and the Aylesbury terrain was achieved by mea

Effects of surrounding buildings on wind pressure distributions and ventilation losses for single family houses. Part 1: 1 1/2-storey detached houses.

This wind tunnel investigation studies the effects of surrounding buildings on the wind pressure distribution over a 1 1/2-storey single-family house. Pressure coefficients obtained in the tests have been used for the calculation of air change rates and associated heat losses from the house for a range of wind speeds and internal-external temperature differences. For these calculations leakage areas in the building envelope have been assumed to be uniformly distributed.

Wind loads on low-rise buildings: a review of the state of art.

This paper reviews the most recent research on wind loads on low-rise buildings. Novel measurement techniques and methodologies are reviewed, and selected experimental results from various studies are presented. Particular emphasis is given to works aimed at the formulation of codified data, ie,results appropriate for incorporation into design standards and codes of practice. Only either full-scale studies or those done under conditions simulating the earth's atmospheric boundary layer have been considered. Comparisons between full-scale and laboratory results are discussed.

Determination of reference wind for the calculation of heat losses associated with change of air in buildings. Determination du vent de reference pour le calcul des deperditions thermiques liees au renouvellement d'air des locaux.

Describes a method to estimate differences in external pressure values between walls from known mean pressure coefficients on the facades and roof of the building in question and from the determination of wind values on the site and at the same height as the building.

Wind-Tunnel Studies of Pressure Distribution on Elementary Building Forms

A systematic series of tests measuring probable distribution of wind pressure on buildings over a practically useful range of building proportions was undertaken using a three dimensional tunnel on a wide assortment of simply gabled block type structures. These tests were then extended to thinwalls, hangar type structures, and simple building groups. The possible effects on building codes and construction techniques are discussed.

The Application of Statistical Concepts to the Wind Loading of Structures

In this paper, the statistical concepts of the stationary time series are used to determine the response of a simple structure to a turbulent, gusty wind. 

Aerodynamic interference between tall buildings - wind tunnel investigations. Aerodynamische interferenz zwischen hochhausern - untersuchungen im windkanal.

Describes wind tunnel experiments on 3-dimensional flow around whole building formations. The pressure distribution on an isolated building with flow over the whole angular range was investigated. This was followed by examination of interference between high buildings of unequal height.

Wind flows and induced pressure on buildings. Application to solar collectors. Ecoulements et charges induits par le vent sur les batiments. Application aux capteurs solaires.

The study, carried out in an atmospheric wind tunnel (reproduction of natural wind conditions, particularly turbulence), quantifies wind flows around built-up obstacles in their realistic location context, and the associated pressure fields. For various types of buildings (detached house, block of flats), the article presents in illustrated form the chart of these flows and pressures in general (mean values, standard deviations, extreme values), but deals more specifically with the wind resistance of solar collectors.
