In the recent past, residential buildings in temperate climates were ventilated by the daily opening of windows and by exaggerated window and door permeability.
Pinto M., Peixoto de Freitas V., Viegas J.C.
Application of ventilation techniques, as well as the use of any passive environmental solution in a rehabilitation, requires knowledge of the particularities of the climate and the specific characteristics of the building stock.
Ganem C., Coch H., Esteves A.
In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building.
Emmerich S.T., Persily A.K.
Natural 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.
Seemi A., Siraj A.
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.
Novosel D., Stetzenbach L.D.
Direct and indirect measuring techniques are available for determination of ventilation rate in naturally ventilated buildings.
Ozcan S.E., Vranken E., Berckmans D.
This paper presents the results of a field study conducted on 31 houses owned by a French social housing management body.
Guillot K., Limoges D., Carrié F.R.
An on-line mathematical approach was used to model the spatio-temporal temperature distribution in an imperfectly mixed forced ventilated room.
Van Brecht A., Quanten S., Zerihundesta T., Berckmans D.
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
Kalagasidis A.S., Mattsson B.
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
Jae-Hun J., Sung-Han K., Jong-In L., Hoi-Soo S., Myoung-Souk Y., Kwang-Woo K.
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.
Emmerich S.T., Persily A.K., McDowell T.P.
The present paper presents the results of the energy and environmental evaluation of ten school buildings in the Greater Athens Area.
Gaitani N., Santamouris M., Mihalakakou G., Papaglatra M., Assimakopoulos M.N, Sfakianaki K., Pavlou K., Paris D., Dimitrios K.
A hybrid ventilation system controlled by a pressure difference sensor was installed on a detached test house.
Yoshino H., Yun S., Nomura A.
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.
Koinakis C.J.
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.
Woloszyn M., Peuhkuri R., Mortensen L., Rode C.
This study considers the link between tertiary buildings design and equipments known as natural and hybrid ventilation or cooling.
Van Moeseke G., Bruyère I., De Herde A.
Industry-wide methods of assessing duct leakage are based on duct pressurization tests, and focus on highpressure ducts.
Wray C.P., Diamond R.C., Sherman M.H.
In these last years, a great deal of interest has been devoted to double-skin façades due to the advantages claimed by this technology (in terms of energy saving in the cold season, high-tech image, protection from external noise and wind loads).
Gratia E., De Herde A.
At the conceptual design stage, one needs to pay considerable attention to both the energy as well as indoor air quality (IAQ) requirements.
Sekhar S.C., Tham K.W, Cheong K.W.
According to the R&D Project on Low Energy Housing with Validated Efficiency, the CO2 emissions due to operation of ventilation systems are estimated to be 7 to 12% of total CO2 emissions of a unit of multi-family buildings in mild climate reg
