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
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.
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.
Technical Evaluation of Solar Desiccant Evaporative Cooling with Solar Absorption and TraditionalCompression Systems | 2006 | English
The use of heat produced by solar thermal collectors is an interesting option for thermal driven airconditioning process. Three technologies are commercially available: absorption, adsorption anddesiccant cooling systems.
The joint IEA research project of ECBCS Annex 43 / SHC Task 34 “Testing and Validation of Building Energy Simulation Tools” contributes to evaluation, diagnosis and improvement of building energy simulation tools.
Conservation Heating to Control Relative Humidity and Create Museum Indoor Conditionsin a Monumental Building | 2006 | English
For the conservation of an important museum collection in a historic building a better controlled indoor climate may be necessary. One of the most important factors is controlling relative humidity.
Improvement of Indoor Air Environment in a Large Welding Factory by Displacement Ventilation | 2006 | English
The design of ventilation equipment is important because it affects the ventilation performancedirectly. To improve the ventilation efficiency of the displacement ventilation, a new ventilation system was proposed in this study.
The Real Life Efficiency of Gas Phase Filters Used in General Ventilation and their Influence on the Indoor Air Quality of an Office Building | 2006 | English
Gas phase filters have been installed within the air handling unit of an HVAC system feeding 100 %fresh (outdoor) air to an office building.
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).
