Stimulating better envelope and ductwork airtightness with the EnergyPerformance of Buildings Directive | 2008 | English
Subtask B of the IEA-ECBS Annex 44"Integrating Environmentally ResponsiveElements in Buildings" deals with thedevelopment and the optimisation of integratedbuilding elements.
Mean and turbulent characteristics of the boundary layer under neutral andunstable conditions | 2008 | English
Prediction and visualisation of wind flow andpollutant dispersion in urban, densely built areasis necessary for city planners and engineers inorder to regulate and monitor successfully thelocal air quality.
The present research was aimed at the definitionof a design hypothesis for the construction of apharmaceutical warehouse in a hot humid areaof southern Sudan.
A wide experimental campaign on transparent advancedintegrated fa~ades with a mechanically, naturally andhybrid ventilated air gap has been carried out both at theDepartment of Energetics at Politecnico di Torino and atLaboratorio Nacional de Enge
Capture Efficiency and Indoor Thermal Environment inside Commercial Kitchen using Low Radiation Cooking Equipment with Concentrated Exhaust | 2008 | English
In commercial ltitchen, a large amount ofheat and moisture as the effluence need to beremoved. Therefore, a large ventilation rate isneeded and energy consumption can be large incommercial kitchen.
Wind speed correction based on the terraincharacteristics is commonly found in severalwind related applications in the builtenvironment.
Energy performance assessment of one DSF active buildings sample in Europe based on clustering analysis. | 2008 | English
A sample of existing double-skin faqade (DSF)buildings distributed across Europe were analysedby means of data clustering.
Building services create customised, user-oriented and controlled conditions for thevarious activities taking place on real estatesand related premises.This paper presents an outlool< of buildingservices trends in Finland.
Laboratory and on-site measurements of natural ventilation rate with solarchimney system | 2008 | English
Development of a unique measuring unit for airflow volume within the vertical shaft of naturalventilation system with solar chimney with theresults of laboratory test and on-sitemeasurement is presented.
Domain decomposition technique is a methodfor CFD simulation, which can handle internalairflow of cross-ventilation of dwellingsseparately from extemal domain.
We are building a particle tracking systemfor the measurement of convective heat transfersand pollutants displacements in full scale rooms.To increase the depth of the zone of interest, thesystem is non stereoscopic and do not use laserlight.
It is often pointed out that when evaluating the energy-saving performance of equipment, it isimportant to take into consideration how theequipment under consideration is actually used.In evaluating heat transfer by contact duringfloor heating, it
CFD Analysis of Airflow Characteristics inside Office Room with Hybrid Air Conditioning-System | 2008 | English
The hybrid air-conditioning system is consistsof natural ventilation and mechanicalair-conditioning system in this paper.
Performance of Whole-building Pressurization as Countermeasureagainst Stack Effect in High-rise Office Building | 2008 | English
This paper deals with pressurization usingHVAC systems on each floor as acountermeasure against stack effect generated inthe winter in high-rise office buildings that donot use revolving doors at the entrance.
Hybrid ventilation free-cooling simulation in Energy Plus. Application on ashopping center retrofitting, in Portugal. | 2008 | English
Buildings take a great share on the total energyconsumption and C02 emissions in Portugal.Poorly thought buildings pollute the urbanspace, and contribute to the increasing buildingssector energy demand.
Simulation on evaluation of Indoor air pollutant difhsed in the crawlspace of detached house | 2008 | English
As the technology in building materialsadvances, the room air pollution caused bychemical compounds, and also by preservativesand insecticides for termite control, has becomea serious problem.
Distribution of contaminants in the occupied zone of a room served by a novel enhanced displacement ventilation system | 2008 | English
The aim of this study is to examine contaminantdistribution in the occupied zone of a room servedby a novel enhanced displacement ventilationsystem which brings cooler air near the floorupward around human body via 4 fans mounted ateach corner of
The concentration in the convection flows ofresuspended particles from the floor area wasexperimentally investigated under laboratoryconditions with different ventilation strategies.It was concluded that the number of smallparticles transported in
In building design the requirements for energyconsumption for ventilation, heating and coolingand the requirements for increasingly betterindoor climate are two opposing factors.This paper presents the schematic layout andsimulation results of an
