Thermal and Air Quality Environment in Elementary SchoolClassrooms Equipped with Air-Conditioning System for Cooling | 2008 | English
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.
Energy-efficient building design often makes use of night-time ventilation or thermal slab activation. The quality of the design tools used depends on the quality of the empirical valuesused within them such as heat transfer coefficients.
The aim of this paper is to have a generaldiscussion of the status regarding energybuilding codes in relation to TAQ concerns.First, there is a brief discussion of the trends inenergy regulations and in IAQ concerns.
According to the definition, passive houses inEurope meet a target energy demand for heatingof less than 15 kWh per square meter and peryear.
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.
In the desiccant dehumidifier using adsorbentsuch as silica gel and zeolite, outdoor moist airis dehumidified in adsorbent.
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.
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.

Impact of the Change of Gross Building-to-Land Ratio upon the ResidentialVentilation Usage and Energy Consumption for Air-Conditioning andLighting | 2008 | English
Tn this paper, using thc "SCTENCE vent"method for estimating the energy consumptionfor air conditioning in rcsidcntial buildings, wcevaluated the wind environment and theradiative conditions with respect to the targetbuildings in the case where th
Subjective experiments on the suitable illuminance in a living room daylitby Mirror Duct System | 2008 | English
The objective of this study is to identify theeffects of mirror duct system on energy savingsfor luminaries.
Today lots of research and application of solarheating are focused on continuously occupiedbuildings, such as residential buildings.
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.
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.
Recently, natural ventilation, which istraditional cooling method in Japan, hasbecome considered as the key method forcooling energy conservation.
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.
In the recent years in Latvia is rapidlydeveloping construction sector of residentialbuildings. Engineers have to give moreattention to heating and cooling system'stechnology in the buildings to stay competitivein the realty's market.
