The Energy Conservation for Buildings andCommunities Systems (ECBCS) is anImplementing Agreement among 23 countriesof the IEA (International Energy Agency) forenergy research and development in buildingsand communities.
Study on evaluation of ventilation effectiveness of occupied space in smokingroom with the highly-efficient ventilation system | 2008 | English
An investigation to understand the actual conditionsof smoking spaces was conducted, and itbecame clear that the introduction of a highlyefficientventilation system is necessary, in additionto the securing of a sufficient ventilationvolume.
Recently, supplying glass space like atrium isbeing extended widely for introducing naturallight into a building, improving rest roomfunctions and having a pleasant workenvironment.
Energy Consumption Pattern in Commercial Buildings to Be Used for Assessing Various Community Energy Systems | 2008 | English
It is believed that one method of maltingeffective use of energy is the sharing ofhydrogen energy or heat and electricityproduced by cogeneration systems at multiplefacilities in the community.
Energy consumed in the Canadian residential sector for space cooling has more than doubled from 1990 to 2002. Cooling requirements, expressed by cooling degree-days have also increased.
A push-pull fume cupboard is a device to capture chemical vapors in a laboratory or a factory.
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.
Thermal mass activation (TMA) can assure, incertain cases, thermal comfort conditionswithout the need of air conditioning systems.Even if other cooling systems have to be used,night ventilation significantly reduces theduration of the working time
There are many technologies aimed at reducing energy demand of ventilation systems, but thefocus in these designs has remained on the airheating system and exhaust losses.
Activated carbon filters have been used forpurification of air and water in industrialapplications.
Considering density of housing in residentialarea of large cities in Japan, it is very difficultto secure sufficient daylight and lead daylightto whole space in the house. High side lightingis one of solutions for such situation.
Parameter Estimation of Dynamic Multi-zone Models for LivestockIndoor Climate Control | 2008 | English
In this paper, a multi-zone modeling concept isproposed based on a simplified energy balanceformulation to provide a better prediction of theindoor horizontal temperature variation insidethe livestock building.
