In this article the concept of a new energy-efficient office building and results of a 3-year monitoringare described.
Kleber M., Wagner A.
Important oversizing factors are observed for room air-conditioners leading to important energy wastes and costly summer peak demands for utilities.
Bory D., Dupont M., Rivière P.
Analytic models and static approaches as the case of Fanger, Deval, Sherman, Gagge, and Stolwijkmodels cannot completely predict indoor thermal comfort.
Harijaona Z., Moujalled B., Cantin R., Guarracino G.
Ventilation is essential for health and comfort of building occupants. It is particularly required to diluteand/or remove pollutants emitted by occupants metabolism.
Richieri F., Michel P., El Mankibi M.
This work lies within the concept of positive energy buildings.
Faure X., Joussellin F., Pierson P., Quenard D.
A method for controlling the temperature of the occupancy zone in a room equipped with a fan coil ispresented. The heterogeneity of the air velocity field and the temperature distribution is considered.
Sempey A., Allery C., Inard C.
Portugal has technical recommendations and standards regarding ventilation rates in naturalventilation systems.
Pinto M. , de Freitas V.P.,Stymne H., Boman C.A.
The use of variable speed pump allows to save energy. Therefore, the impact of these technologieson the heating system and thermal comfort in buildings is rarely highlighted.
Couillaud N.,Riederer P., Diab Y.
The use of electricity in buildings constitutes around 16% of Singapore’s energy demand. To incorporate energy efficiency measures is one of the key mission to ensure that the economy is sustainable.
Lee S.E., Priyadarsini R.
Although the concept of ventilation has been around for several thousand years, the application of ventilation to overcome low productivity in warm to hot climates has been neglected over the last few decades.
Harmsworth B.
Although unanimously acknowledged by the experts for its performances as regards energyeffectiveness and indoor air quality optimisation, humidity sensitive ventilation still too often suffersfrom a lack of knowledge inherent in its singularities.
Savin J.L., Jardinier M.
Air leakages can cause a significant energy penalty, inability of the heating system, and failure of the ventilation system – especially in passive houses. However, they can be avoided if given serious consideration in the design phase.
Dorschky S., Rolfsmeier S.
The cooling loads of an office building vary with the desired indoor thermal climate.
Heikkilä K., Lindholm T.
Available time for building construction is getting shorter, therefore the number of buildings which are built with lightweight building elements (LBE) is increasing.
Cerne B, Medved S.
Demand-controlled ventilation (DCV) has largely been documented in the literature through fielddemonstration projects and computer simulation studies.
Tissot A., Archenault M.
The passive cooling techniques such as night time cross ventilation is potentially an interesting strategy to provide substantial cooling energy savings in warm climates.
Salmerón Lissen J.M., Sánchez de la Flor F.J. , Álvarez Domínguez S.A., Ruiz Pardo A.
The purpose of this study is to determine how levels of ventilation rates and indoor air quality vary in elementary schools in southern Japan. This study is based on field monitoring carried out as intermittent monitoring from summer to winter.
Iwashita G.
The potential for passive cooling of roof slabs incorporating an air cavity is important with respect tothermal comfort.
Borg R.P.
The aim of this work is to study the influence of global heat transfer coefficient (Utot en W/m2.K) of the opaque walls (walls and roofs) and of the glazed walls (bays) on the annual consumption of heating, cooling and overall consumption energy.
Filfli S., Marchio D.
The energy consumption of a building is evaluated by neglecting the heat loss which can occur when the air passes through the envelope.
Barhoun H., Guarracino G.
