In order to save energy for building cooling during hot days in regions with cool nights, air circulation throughout the interior of the building has been envisaged as a means to lower the temperature of the building structural mass.
This paper describes the results of a collaboration study between ENTPE-LASH and LEPTAB within the framework of the IEA Annex 35 “Hybrid Ventilation in New and Retrofitted Buildings”.
The main objective of our study was to know more about indoor air quality in offices building over a long period. Our study has been carried out in one building located downtown Lyon (France).
An energy balance over an urban area and over a rural one, reveals that the first case is always more complex than the last one. The urban context is able to change all the energy transferences mainly due to its own layout.
This paper is divided into tree main sections, ‘Introduction to natural ventilation’, ‘Examples, strategies and results’ and ‘Energy consumption’.
In this work, experiments were carried out to estimate deposition rate of 5µm particles powder in large cylindrical straight ducts for different diameters. Two types of ducts were compared: rigid ducts and flexible ducts.
Parametric analysis applied to the thermal performance evaluation of low-cost houses : a case-study in Curitiba, Brazil | 2002 | English
The construction of dwellings for people with low incomes in developing countries encompasses a broad range of issues starting from the choice of the building site, to the construction phase and finally to the evaluation of the building itself.
The Solar-Campus Juelich consists of two buildings, as part of the University of Applied Sciences, Aachen, and student dormitories for 136 students (5 row houses), see Figure 1.
Modelling the effect of ventilated air cavities in the solvent prototype : a reversible solar screen glazing system . Preliminar results | 2002 | English
To evaluate the impact of the natural ventilation of the air cavity in the prototype of the glazing system being studied in the frame of the project SOLVENT, funded in part by the Commission of the European Union, a prototype of a reversible natur
Ventilation efficiency under various heating and air-exhausting conditions : an experimental study. | 2002 | English
This work, along with the experimental measurements on which it is based, was carried out in the framework of research undertaken by the French “Groupe de Pilotage sur la Qualité des Ambiances” (GPQA), whose task was to initiate and co-ordinate wo
Measurements of wind speed and wind direction, air temperature inside and outside an urbancanyon also infrared radiation in buildings have been measured on summer 2001 in Athens, in fivedifferent urban canyons, in the frame of Urbvent project.
Design, monitoring and evaluation of a low energy office building with passive cooling by night ventilation | 2002 | English
In moderate climates, one promising feature to reduce the energy demand of office buildings for air conditioning without reducing comfort is passive cooling by night ventilation.
Optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices. | 2002 | English
The aim of this paper is to explain the results of a research project run in Yildiz Technical University which focuses on the optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices placed in Istanbul
In conventional construction, the ventilation air enters a building through a combination of ‘desired’ pathways, via opened apertures, such as a window, vents, and ‘undesired’ pathways, via cracks such as around external openings, joints between b
The combination of an open wet cooling tower with chilled ceilings is a CFC free, cheap and low energy cooling solution. The efficiency of this alternative to mechanical cooling is very dependent on climate.
This paper presents the results of a series of specially designed experiments to study moisture transport across bonded or natural contact interfaces between building materials.
About 100 office buildings in the Flanders and Brussels regions have been subject to a surveyof energy aspects and indoor climate parameters.
Nowadays the awareness concerning the environmental pollution and the demand of transparent facades in architecture, lead research in finding new solutions to increase the energy performances of the building and the installations as well.
This study investigates the behavior of vapor in a ventilated room in which vapor is being produced.
