The GENHEPI Concept: a New Methodology for Low Energy Consumption Building RenovationDemonstration Program | 2006 | English
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
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
