A roof is one of the most importantcharacteristics of Thai architecture especiallyin a house, traditionally. Also, the roof is apart of the house that mainly effects energysaving due to heat allowance pass through andrelease from indoor space. The study, basedon model experiments, targets to find out theeffects of roof forms on indoor air temperature.The purpose is to give information for roofform types selection in Thai Houses. Models,lxlxl meter boxes, are used for theexperiments by changing their roof forms forcomparison.

This study aims to derive design data of thesupply chilled water temperature and water flowrate for the radiant floor cooling system inKorean residential buildings. At first,prEN- 1264 standard and ASHRAE method forthe radiant floor cooling system design werereviewed. Secondly, to verify application of thestandard, moclc-up tests were performed. Theresults show that prEN-1264 method isappropriate in case supply chilled watertemperature is low.

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 responses andenvironniental quantities obtained from twoexperimental small wooden buildings: one has aradiative cooling system on the ceiling and theother has a conventional convective coolingsystem.

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. Thus, an experimental facility for investigationof room ventilation and indoor heattransfer has been built at Biberach University ofApplied Sciences in Germany. lnitial tests havebeen conducted investigating natural convectionheat transfer with an electrical heating elementon the floor.

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. First, weset up two rooms in an experimental apartmentbuilding: one has radiative cooling panels andexternal shading; and the other internal shadingalone. The panel surface temperature of theradiative cooling was controlled atapproximately 24 C and the water to besupplied in the panel was produced by a heatpump system.

The effect of downdraft spoilers is questioned.CFD results are presented for a large atriumequipped with downdraft spoilers ("obstacles")to counteract downdraft from glazed faqades.Simulations are in addition presented for oneandtwo-story test rooms, where aspects of theefficiency of downdraft spoilers are investigated.Among conclusions are that the spatial thermalbalance of rooms, e.g. stratification or otherbuoyancy driven flows, are essential to thedowndraft, more so, than downdraft spoilers.

This field work was conducted in Wuhan in2007 summer to investigate local residents'thermal adaptation. A total of 367 residentsanswered questionnaires and 69 familiesprovided 348 data sets including residents'demographics information, thermal sensation,corresponding indoor and outdoor climaticcondition, housing characteristic and residents'adaptive behavior. The investigation has shownthat local residents can tolerant more rigorousthermal environments comparing with theranges defined by ASHRAE.

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. Thisstudy analyses mold rislzs based on a mixedsimulation approach. This approach requires areliable aggregation method to arrive atquantified mold growth risk and extension ofstandard simulation capacity to account for additional mechanisms of the moldphenomenon.

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. To address a comprehensive assessment, an exergy assessment methodology is put forward in this paper. Furthermore, in existing China's statistical yearbook, there is no specific item for building energy use. This paper processes analysis for statistical yearbook and acquires relevant rough data of building energy use.

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. by switching on anair-conditioning unit or opening a window,influences significantly on the exergy balance ofthe building systems.
