Thermal adaptation in residential buildings in the Hot Summer and WinterCold Zone of China, case study of Wuhan in summer | 2008 | English
This field work was conducted in Wuhan in2007 summer to investigate local residents'thermal adaptation.
Translucent thermal insulation walls forJapanese houses have been designed to allowsolar radiation and daylight to pass through thewalls into the house (Fig.
A com~nonp ractice, adopted by several buildingenergy simulation (BES) tools, is the use ofsurface averaged wind pressure coefficients (Cp)instead of local Cp values with high resolutionin space.
Buildings are a man-made environment built innature.
A survey of air conditioner temperaturesettings and clothing insulation was carried outfor university student rooms in June-Octoberduring daytime on weekdays in Osaka, Japan.The results are as follows.
Experimental Study on Thermal Cognition Developed through DailyExperience in the Built Environment during Summer Seasons | 2008 | English
This paper discusses whether there is thermalcognition acquired through daily experience inthe built environment during summer seasons.For this purpose, we analysed the results of asubjective experiment to reveal the relationshipbetween subjective
Conventional air-conditioning control in a roomassumes perfect diffusion of temperature in theroom, and relies on a temperature sensorinstalled on the wall or ceiling of the room, or inthe return duct.
Exergy assessment of building energy use in China's hot summer and cold winter climate zone | 2008 | English
BEU accounting and assessment is a fundamental task for development of energy efficiency in buildings. The traditional methodology is based on caloric value of energy carriers, which is only relates to energy quantity.
Sales data shows that the use of air-to-air heatpumps in New Zealand houses is rapidlyincreasing. This rapid uptake will lead to newenergy and peak power demands on theelectricity supply system.
Thermal building simulations (TRNSYS) werelinked to nodal airflow network simulations(COMIS) for a detailed ventilated double-skinfacade calculation of performance.
Efficiency of Energy Conservation Methods on Space Conditioning Loadof Residential Buildings | 2008 | English
As a matter of national policy, we have tochallenge to save energy in residential sectorthat contribute to C02 emission because theKyoto protocol has talten effect in 2005.
BEMS and HVAC Control System Utilizing Simulation andthe Data Platform on the Internet | 2008 | English
This paper describes the optimum HVACcontrol system that the simulation is executedusing the data of BEMS and the weatherforecasting, etc.
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.
Tokyo Electric Power Company R&D Center wascompleted in September 1994.
