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
Buildings are a man-made environment built innature.
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.
A push-pull fume cupboard is a device to capture chemical vapors in a laboratory or a factory.
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.
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.
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.

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.
This paper presents a design method to definethe settings of HVAC systems in order toprovide thermal comfort in high MRTenvironment in hot climates.
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.
Recently, natural ventilation, which istraditional cooling method in Japan, hasbecome considered as the key method forcooling energy conservation.
