LoginNatural ventilation reduces energy consumption for fans and mechanical cooling and in mostcases gives occupants control over their office space. Further benefits include no fan noise and insome cases elimination of the mechanical cooling system.

Indoor environmental quality, energy usage and occupant perception in commercial office buildings | 2005 | English
A multi-disciplinary study to comprehensively measure and analyze operational performance and indoor environmental conditions in a sample of typical, commercial office buildings in the United States is described.
This paper presents the results of a field study conducted on 31 houses owned by a French social housing management body.
An on-line mathematical approach was used to model the spatio-temporal temperature distribution in an imperfectly mixed forced ventilated room.
This study investigates numerically the occurrence and duration of higher relative humidities in a cold attic space, which are a consequence of excessive moisture supply from ventilating the attic and from air infiltration from inside the dwelling
Prediction of buoyancy-induced pressure difference across exterior walls of high rise residential buildings | 2005 | English
It is very important to estimate the stack pressure difference across exterior walls for understanding the energy impacts of infiltration and ventilation in high-rise buildings, because stack pressure is likely to significantly affect energy load
Impact of commercial building infiltration on heating and coolin loads in US office buildings | 2005 | English
With the exception of a few analyses of the impacts of ASHRAE Standard 62-89 and energy use in specific buildings, the energy use in commercial building due to infiltration and ventilation flows has received little attention.
The present paper presents the results of the energy and environmental evaluation of ten school buildings in the Greater Athens Area.
Performance evaluation of the hybrid ventilation system controlled by a pressure difference sensor | 2005 | English
A hybrid ventilation system controlled by a pressure difference sensor was installed on a detached test house.
In this paper the effects of atrium and other similar architectural design features (e.g. shafts) on ventilation efficiency are examined in a multi-storey office building.
The paper gives an outline of existing modelling capabilities as well as an overview of current developments in integral modelling of hygrothermal conditions for whole buildings as presented within IEA Annex 41.
Development of design guidelines for tertiary sector buildings equipped with natural ventilation systems | 2005 | English
This study considers the link between tertiary buildings design and equipments known as natural and hybrid ventilation or cooling.
Industry-wide methods of assessing duct leakage are based on duct pressurization tests, and focus on highpressure ducts.
