The paper evaluates the potential work performance benefits of increased ventilation. We analysed the literature relating work performance with ventilation rate and employed statistical analyses.
Ventilation Performances of Mixing, Displacement, and Impinging Jet System under Different HVAC Scenarios : Part I | 2006 | English
In most conditioned spaces, the Mixing Jet Ventilation (MJV) systems are commonly installed. Relying on turbulent mixing, MJV homogeneously controls the room environment.
The paper presents the evaluation of the current HVAC components and indoor climate of a high tech Naval Depot in case of failure events.
Indoor Environmental Criteria for Design and Calculation of Energy Performance of Buildings -EN15251 - | 2006 | English
European Directive for Energy Performance of Buildings (EPBD) was approved in the beginning of2003. The transition period is 3-6 years depending of the article.
The GENHEPI Concept: a New Methodology for Low Energy Consumption Building RenovationDemonstration Program | 2006 | English
French buildings highly contribute to the total national energy consumption.
Indoor Air Pollution with Fungus inside Well Insulated Houses - Biological Aspects - | 2006 | English
Since the energy-crisis of the 70’ies, the trend goes to energy-saving constructions, that have strongly changed our way of building.
Influence of Air Leakage in Building’s Walls on Heat Transmission Loss through its Envelope | 2006 | English
The energy consumption of a building is evaluated by neglecting the heat loss which can occur when the air passes through the envelope.
Consequences of Increasing Insulation on the Annual Energy Consumption of Air-Conditioned Office Buildings | 2006 | English
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.
CFD Modeling of Heat Convection in a Large Cross-section Earth-to-Air Heat Exchanger | 2006 | English
An Earth-to-Air Heat Exchanger (ETAHE) is a low energy cooling and heating technology for buildings.
In this study the COwZ model (COMIS with sub-zones) was modified to allow dynamic simulations ofindoor thermal conditions, humidity and pollutant transport and concentrations throughout wholebuildings.
A TRNSYS Component to Calculate Natural Ventilation and Indoor Air Quality in Multizone Buildings | 2006 | English
The prediction of air infiltration is very important when simulating a building, due to the couplingaspects of the thermal and ventilation problem.
The thermal exchanges between the buildings and its surroundings may be easily evaluated from balance equations.
