Thermal comfort evaluation: a study in workplaces at the clothing industry in Brazil

Then main objective of this work is to create subsidies for an analysis of Predicted MeanVote (PMV) from ISO 7730 (1994), for thermal comfort evaluation in Brazilianworkplaces. The clothing industry in the city of Amparo, So Paulo State, was chosen forthe study. A survey among the workers was carried out through questionnaires, collectingdata about thermal sensation, clothing and workers activities. Dry and wet bulbtemperatures, globe temperatures and air speed were also measured, simultaneously to thequestionnaires.

Do People Like to Feel ‘Neutral’? Systematic Variation of the Desired Sensation on the ASHRAE Scale of Subjective Warmth.

This analysis explores the pattern of variation of the desired thermal sensation on theASHRAE scale, applying for the first time the method of direct enquiry. Data are fromstudies of thermal comfort at university lectures and in dwellings. Respondents reportedboth their thermal sensation and the sensation they would have desired at that time. Thedata contain 868 comparisons of the actual and the desired sensation. On 48% ofoccasions the desired sensation was other than neutral.

New Life – Old Structure

Two thermal comfort surveys of people living in two types of naturally ventilatedhousing: traditional courtyard housing and apartment flats performed in Yazd Ilam arepresented in this article. The first study took place in the Iranian city of Yazd, whichexperiences a hot, dry climate. Over 420 subjects in 32 courtyard housing and 39 flatsresponded to thermal comfort questionnaires. At the same time physical and individualmeasurements were taken.

Residential Thermal Comfort, Weather- Tightness and Ventilation: Links With Health in a European Study (Lares)

The LARES Housing and Health survey conducted in representative samples of eightEuropean towns provides substantial data from 3,373 households about housingconditions and the health of 8,519 residents. We assessed the relation between residentialthermal comfort, weather-tightness, ventilation, mould or dampness and some commondiseases and symptoms. We observed that reporting bad health was significantlyassociated with temperature, weather-tightness and mould or dampness problems.Asthma was significantly linked with mould or dampness, temperature, and ventilationproblems.

The architectural design of obstetrical suites, A thermal comfort contribution

The fundamental proposition in this work is to introduce alternatives and technicalrecommendations to improve thermal comfort and low energy through architecturaldesign in healthcare spaces of obstetrical suites. It analyzes lighting and air conditioningplanning issues and the specific circumstances of the women and the newborn'shealthcare components to high quality birth care.

How adaptive comfort theories might influence future low energy office refurbishment strategies

With the UK commercial sector only replacing buildings at 1-1.5% per year adaptationsto existing buildings are needed to maintain comfort levels, while reducing energy useand carbon emissions. In this study, occupants of a refurbished office recorded theirthermal sensations, assessment of lighting and air movement, perceptions of comfort andtheir reactions to adaptive opportunities. The observed mean thermal sensation votes andthe overall comfort votes correlated best with mean diurnal internal and externaltemperatures, respectively.

Thermal comfort in buildings located in regions of hot and humid climate of Brazil

The present work was developed in 2005 in a Brazilian region of hot and humid climatewith volunteers performing sedentary activity. The predicted mean votes (PMV) , thethermal sensation votes (TSV) and the thermal preference votes (TPV) were acquired andcalculated according to the standards ISO7726 ISO7730 and ISO10551. PMV and TSVdid not show good correlation in naturally ventilated buildings. Differences were alsofound in those environments with the application of the methodologies proposed byHumphreys and Nicol and Fanger and Toftum.

Getting it (Almost) Right: Some Studies of Comfort in Recent Australian Buildings

This paper reviews the results of a series of studies carried out since the early 1990’s to assess the performance of approximately 50 naturally ventilated, hybrid ventilated or air conditioned buildings in Sydney, Australia. A number of significant case
