Revisiting Internal Pressure Dynamics in a Single Opening Enclosure Ventilated by Wind | 2011 | English
Investigation of Ventilation Effectiveness for Wind-Driven Single-Sided Ventilated Buildings Located in an Urban Environment | 2011 | English
This study employed large-eddy simulation (LES) to investigate wind-driven single-sided natural ventilation for an idealized building model located in an urban environment.
A model tunnel (approximately ten hydraulic diameters) with different designs of the tunnel mouth has been placed in a wind tunnel and has been subjected to the effects of external wind by varying the wind direction at the mouth of the tunnel.
Although it has been used for many years in commercial buildings, the application of demand controlled ventilation in residences is limited.
Ventilation Strategies in School Buildings for Optimization of Air Quality, Energy Consumption and Environmental Comfort in Mediterranean Climates | 2011 | English
This study copes with the problem of ventilation in existing educational environments in terms of indoor air quality (AIQ), comfort and energy consumption.
The ‘Wind-Rain’ House, was designed by the New Zealand architect, Nigel Cook. First built in New Zealand in 1985 its design concept for indoor thermal comfort is quite different from local conventional houses.

A Study on the Convective Heat Transfer Coefficient and Thermal Resistance of Clothing under Cross Ventilation | 2011 | English
The convective heat transfer coefficient around the human body is important for evaluating the effects that airflows exert on thermal comfort. However measuring it is generally difficult.
The issue of evaluating possible strategies for improving the building stock's energy and environmental performance is crucial. This applies to all buildings including residential and non-residential.
Old buildings represent, in many countries, a great part of the existing building stock. In France this amounts to more than 30%. It is important that they are retrofitted to improve energy performance.
