In Cuba the climate is tropical, with average solar radiation of 5.5 kW-h/m2and an annual average temperature of 25 °C. The relative humidity is high all of the time, with an annual average between 75 % and 85%.
The paper presents the evaluation of the current HVAC components and indoor climate of a high tech Naval Depot in case of failure events.
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.
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.
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.
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.
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.
The thermal exchanges between the buildings and its surroundings may be easily evaluated from balance equations.
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 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.
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.
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.
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

In most conditioned spaces, the Mixing Jet Ventilation (MJV) systems are commonly installed. Relying on turbulent mixing, MJV homogeneously controls the room environment.
Effect of Cleaning of Residential Ventilation System on Fan Energy Use and Ventilation Performance | 2006 | English
Regular maintenance, such as the cleaning of filters, is important for the efficient operation ofresidential ventilation systems.
