Condensation and mold growth risks on interior surface of a corner wall in anapartment | 2008 | English
The paper presents the results of mold growthrislzs in a corner wall near an entrance door inan apartment house. The corner wall isrecognized as a trouble spot for condensationand mold risk in apartment buildings.
Thermal and Air Quality Environment in Elementary SchoolClassrooms Equipped with Air-Conditioning System for Cooling | 2008 | English
An investigation was performed in a middle-corridor-type elementary school in Tolcyo, Japan, equipped with an air-conditioning system for cooling.Temperatures and C02 concentrations weremeasured in classrooms, corridors and outdoors.Visual inspect
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
Experimental Investigations of the Turbulent Mixing Process and theReynolds-Stress Anisotropy Tensor in Ventilated Rooms | 2008 | English
In the past various experimental investigationsabout room airflows were published.
Buildings are a man-made environment built innature.
According to the definition, passive houses inEurope meet a target energy demand for heatingof less than 15 kWh per square meter and peryear.
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.
Comparison of imagined and real behaviors in relation to active coolingmethods under Japanese summer conditions | 2008 | English
Recently post-occupancy evaluation is oftenused to know the actual performance of socalledenergy saving building components andto compare with simulated performance. Inreality, the occupants choice how to achievecomfortable conditions, e.g.
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.
The holistic aim of this study is to make clearthe possibility of passive cooling systems usingnatural cool sources produced by cyclic weatherchanges. Here in this study, we focused on apossible use of rainwater for cooling.
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.
The IEA ECBCS: Research and Development for Near Zero Energy and Carbon Emissions in Buildings and Communities | 2008 | English
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.
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.
Recently, supplying glass space like atrium isbeing extended widely for introducing naturallight into a building, improving rest roomfunctions and having a pleasant workenvironment.
A push-pull fume cupboard is a device to capture chemical vapors in a laboratory or a factory.
This paper presents a design method to definethe settings of HVAC systems in order toprovide thermal comfort in high MRTenvironment in hot climates.
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.
People who become too warm or too cool willadjust their clothing or reset building controls(windows, blinds, fans, thermostats) with theainz of restoring comfort or reducingdiscomfort, if they are free to do so.
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.
