Energy Efficiency Improvements through Sunspace Augmented Positive Input Ventilation of Buildings | 2006 | English
Positive input ventilation (PIV) systems were installed in a new build housing development inBallantrae in south west Scotland; utilising a glazed sunspace on the south elevation of each dwelling to augment the energy saving potential of the insta
Energy Efficient Office Buildings with Passive Cooling Results from a Research and Demonstration Programme | 2006 | English
To gain access to information on energy use in office buildings, the German Federal Ministry forEconomy launched an intensive research and demonstration programme in 1995.
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned.
Modelling of Coupled Heat Transfer and Mass Transfer In Unconditioned Buildings :Application to the Winter Thermal Comfort. | 2006 | English
Modelling thermal and aerial behaviour of unconditioned buildings requires an accurate knowledge of the air temperature and velocities fields inside the considered spaces.
Numerical Evaluation of Earth to Air Heat Exchangers and Heat Recovery Ventilation Systems | 2006 | English
Balanced ventilation systems with heat recovery and earth to air heat exchangers are interestingtechniques, which can reduce heating and cooling demand of buildings, and improve internal thermal comfort.
The optimization of building thermal performance has traditionally been based on designers’ experience.
The average air tightness of the ventilation ductwork in France is rather poor, corresponding toa 3A class. This is mainly due to air leakage in the fittings.
Application of scale models along with the use of wind tunnel testing facility have been the primary tool used in building aerodynamic studies by architects and planners.
Why HVAC Certification for Balancing and Commissioning Contractors is Necessary for VentilationMeasurement, Verification, Validation and Decreased Energy Consumption | 2006 | English
This presentation will make the audience aware of the importance of ISO-recognized certificationprograms in the testing adjusting and balancing and commissioning of HVAC systems.
This article presents the application of the zonal approach for modeling airflow and temperaturedistribution in Doube-Skin Facades (DSF).
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.
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 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.
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.
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.
