Indoor Environmental Criteria for Design and Calculation of Energy Performance of Buildings -EN15251 - | 2006 | English
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.
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.
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.
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.
The paper discusses a methodology for thermal analysis applied to buildings in which the stochasticnature of the external forces is concerned. The considered forces are ambient temperature and solarradiation.
The actions to limit the energy consumption and the electricity demand lead in Europe and inFrance to think about the energy labelling of the consumption of the fans used in ventilationsystems.
In this study the question whether or not and to what extend ventilation and air cleaning can contribute to the reduction of exposure to environmental tobacco smoke in the hospitality industry is answered.
Utilization of Solar Energy Systems for Retrofit Design of School Buildings and an Example Application | 2006 | English
As a large part of the education year occurs during the cold weather season, the proportionally largeglass areas permit excessive heat loss in the classrooms.
Ventilation Performances of Mixing, Displacement, and Impinging Jet System under Different HVAC Scenarios : Part II | 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 idea proposed in this paper is to control the HVAC equipment with predicting the heating/cooling loads and indoor conditions by computational simulation according to the target, such as energy consumption, energy cost, CO2 generation and indoo
