Performance assessment of an indoor LED illumination incorporated withthe building environment control system | 2008 | English
The target of this study is to investigate aninnovative indoor LED illumination that usesheat pipes as the heat transfer channels toconduct the released heat of the LED to theheat-sink fins on the two sides.
Measurement on Energy Conservation of Heat Pump Air ConditioningSystem Employing Energy Recovery Ventilation in an Office Building | 2008 | English
It is known that there are some methods ofenergy conservation for building facilities.Energy recovery ventilator (ERV),which canrecover sensible heat and latent heat, is one ofthe solution to reduce heatinglcooling loads,which are related to the p
Outdoor airflow rates and convection airflow in a model house with the passiveventilation design | 2008 | English
Recently most houses in northern Japan have becomehighly insulatedand airtight, whichhave caused seriousproblems such as indoor air pollution.
Integrating active thermal mass strategies with HVAC systems in officebuildings: development of a concept design tool | 2008 | English
Thermal mass can be used in buildings toreduce the need for and dependence onmechanical heating and cooling systems whilstmaintaining environmental comfort.
This paper describes thermal characteristics of a hydronic floor heating system using heat pumps. An experimental system is constructed in a climate chamber. It has a test room with a floor area of 1 1.6 m2 and an air volume of 23.15 m3.

The quality of a hydronic energy system isinfluenced by supply and return temperatures.Instead of using the exergy term, a TEA(Temperature and Energy Accumulated) curveis introduced for evaluating an examplifiedplanned 100 GWh district heating sys
The productivity of occupants in classroomsdepends strongly on the indoor air quality andthe thermal comfort. Three ventilation conceptswith different arrangements of supplyand exhaust openings are presented as solutionsin this study.
Evaluation of effect of the wind pressure fluctuation for cross ventilation in the residential district | 2008 | English
In residential district, it is difficult to setappropriate wind pressure coefficient for crossventilation design, because there are various andcomplex parameters that influence the windpressure.
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
