Determination of the Chilled Water Temperature and Flow Rate of theRadiant Floor Cooling System in Residential Buildings | 2008 | English
A new innovative design concept for the indoorair conditioning systems is proposed. Thisconcept uses passive control and modularly airdiffusion devices and aims complying with boththernial conifort and energy efficiencyobjectives.
In this work the problem of the estimation of achange in the dynamics and time-varyingthermal parameters for a wall from experimentaldata is solved in several ways.
A Study on Thermal environment of the Raised-Floor Ondol with aVentilation System at an Apartrnent | 2008 | English
A radiant heating applied to floor, so called'Ondol', is a traditional heating method in Koreaand has been widely used.
The aim of this paper is to have a generaldiscussion of the status regarding energybuilding codes in relation to TAQ concerns.First, there is a brief discussion of the trends inenergy regulations and in IAQ concerns.
Honda Wako Building(hereinafter called HWB)" is ahigh efficiency saving energyoffice building with six floorshaving 52,138-m2 of total floorarea.
Energy-efficient building design often makes use of night-time ventilation or thermal slab activation. The quality of the design tools used depends on the quality of the empirical valuesused within them such as heat transfer coefficients.
Development of behavioural algorithms for thermal simulation of buildings- evaluating constraints on the operation of windows and fans | 2008 | English
Realistic knowledge of window-opening andfans use behaviour is needed, for the thermalsimulation of naturally ventilated buildings. Ifcontrols such us windows and fans wereefective and easy to use, thermal discomfortcould be largely avoided.
Experimental and numerical study of air temperature distribution of anunderfloor air distribution system | 2008 | English
A numerical model of an underfloor air distribution system was created to aid future research on the system's environmental performance. A validated numerical model can serve to minimize the need for costly experimental setups.
In the desiccant dehumidifier using adsorbentsuch as silica gel and zeolite, outdoor moist airis dehumidified in adsorbent.
A Study on the Filtering Impact of Plants and Soil on the Reduction ofVolatile Organic Compounds | 2008 | English
The research regarding the importance of indoorair quality is recently becoming issue fromKorea and various methods are being used toimprove interior air quality.
Cross ventilation analyzed by recording pressure distributionon the floor of wind tunnel models | 2008 | English
Cross-ventilation is difficult to predict andcontrol because wind exhibits a large degree ofvariation in both speed and direction.Consequently, the design of a well functioningcross-ventilation system presently demandsthorough and often expensive
The building sector is the first responsible ofenergy consumption in France (about 43%).Improving procedures, simulation tools anddesign methods should go in parallel withefforts to enhance the energy efficiency and tofind optimal design solutions
Computer model and simulation of a traditional passive cooling ventilationsystem in a modem building in Mazara Del Vallo (Italy) | 2008 | English
Traditional and modem natural ventilationtechniques have been integrated in a hybridsystem for a retrofitting of a public building inthe city of Mazara del Vallo (Ttaly).
DX A/C systems are widely used insmall to medium size building and generallyrely on On-Off control as a low-cost approachto maintain only indoor dry-bulb temperature.Continuously running the supply fan in a DXA/C system has a significant influence
Impact of building morphology, thermal inertia and glazed area on theenergy consumption of residential houses | 2008 | English
This paper presents the energy savings thatcould be obtained by the appropriate design ofthe building in terms of morphology, thermalinertia and glazed area.
Reinforcement of air-tightness and thermalinsulation in the indoors leads to the declinein air-change rate.
Study on energy conservation effects of wind-induced ventilation indetached house using coupled simulation of semi-empirical ventilationmodel and network models | 2008 | English
A semi-empirical ventilation model was proposed for cross-ventilation. This model isbased on local dynamic similarity theory andwas coupled with COMIS and TRNSYS, whichare widely used for energy conservationsimulation.
Nowadays, due to the energy saving purposes inthe building sector, at new buildings and atrefurbishments, modem closing elements arebuilt-in, with very good thermal insulation andair tightness properties.
designed "air-curtain chemical fume hood" arediagnosed by using the tracer gas concentrationdetection method.
