LoginThe air conditioning of large non-domestic buildings is becoming an increasing trend, even in moderately mild climatic zones. This is often needed to avoid overheating that results from high internal heat gains and solar radiation.

Natural ventilation and low energy cooling of large, non domestic buildings - Four case studies - | 2005 | English
The work described in this paper formed part of the European UrbVent project on urban ventilation.Measurements of wind speed, wind direction, and air temperature were made at four different heights, inside a pedestrian street canyon in the centre
This paper introduces a concept of robustness of an air distribution method, which is defined as being capable of meeting the ventilation requirements during varying operational conditions.
Roof-Mounted Ventilation Towers – Design Criteria for Enhanced Buoyancy-Driven Ventilation | 2004 | English
Ventilation towers are often incorporated into the design of naturally-ventilated buildings. These towers increase the physical height of the building and thereby potentially enhance the buoyancy-induced air velocity.
This research grows out of a desire to find a Solar-Wind Generated Roof Ventilation System for low-cost dwellings located in high building density urban areas where horizontal air movement is restricted.
This paper reviews the current literature on discharge coefficients (CD) of openings and compares different studies for wind-driven cross-ventilation.
Wind Tunnel Study for Estimating Outdoor Ventilation in a Dense Low-Rise Building Area | 2004 | English
To accurately estimate the natural ventilation of outdoor spaces surrounded by low-rise buildings using a wind tunnel requires correct representation of the natural wind regime combined with appropriately scaled building models and testing method.
Top down natural ventilation systems, usually referred to as ‘windcatchers’, have been used recently in modern non-domestic buildings in the UK.
ZAER: A Zonal Model for Heat Transfer and Air Flow in Unconditioned Buildings - An Experimental Validation | 2004 | English
This paper presents a three-dimensional zonal model, ZAER, for heat transfer and air flow calculations. It is based on an intermediate approach between single-air-node and CFD models.
A zonal model is an intermediate approach between computational fluid dynamics (CFD) and single-room models. It can give results faster than CFD and be more accurate than single-zone models.
