Translucent thermal insulation walls forJapanese houses have been designed to allowsolar radiation and daylight to pass through thewalls into the house (Fig.
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.
In recent years, the insulation and air-tightnesslevels of newly constructed houses in Japanhave been improved for purpose of energysaving. However, a reduced design of airpermeability (i.e.
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.
This paper discusses the possibility of asimple solar hot water pre-heating system fordomestic hot water supply. In Japan, the fossilfuel use for hot water supply amounts to about30% of the total in residential buildings.
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.
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.
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.
This paper describes the history and background of the ventilation requirements. Thepaper starts with an overview of existinginternational requirements.
Thermal building simulations (TRNSYS) werelinked to nodal airflow network simulations(COMIS) for a detailed ventilated double-skinfacade calculation of performance.
