Thus, the objective of this research is to evaluate the thermal comfort conditions of classrooms and administrative rooms, naturally ventilated, in a building of higher education, in the city of Campina Grande, Northeast Region of Brazil, where the weather is predominantly hot and humid. In order to obtain the results, two methods traditionally used in this type of research were applied. The analytical method, included in International Standards ISO 7730 (2005) and ASHRAE 55 (2010), provides results on 4 environmental and 2 personal variables, collected from the studied environments. The second method consists in the application of questionnaires to the ordinary users of the environments aiming to obtain personal answers about the real thermal sensations. The analysis of the results showed that the comfort zones, verified in the building, were distinct for each season of the year in which the research was developed. By personal votes, the comfort temperature ranges in the fall were broader than those provided by the technical standards. However, in the winter, the normalized method overestimated the ranges of comfort temperatures obtained by direct votes. The results of the thermal comfort zones were compared with those of other studies done in regions with climatological features similar to those of this work, as well as with those obtained in regions of colder climates, verifying the coherence between the data. This research concluded that, in the autumn season, the environments of the building provided its occupants with thermal discomfort for the heat most of the time, however, in the winter season, thermal comfort situations were predominant. / A importância do estudo do conforto térmico em edificações de ensino está associada ao vínculo que essa condição tem com o desempenho de atividades humanas, para as quais um ambiente termicamente confortável proporciona melhores níveis de concentração e atenção. Assim, o objetivo desta pesquisa é avaliar as condições de conforto térmico de salas de aula e salas administrativas, naturalmente ventiladas, de uma edificação de ensino superior, na cidade de Campina Grande, na Região Nordeste do Brasil, onde o clima é predominantemente quente e úmido. Para obtenção dos resultados, foram seguidos dois métodos tradicionalmente utilizados nesse tipo de pesquisa. O método analítico, constante nas Normas Internacionais ISO 7730 (2005) e ASHRAE 55 (2010), fornece resultados a partir de 4 variáveis ambientais e 2 pessoais, coletadas no interior dos ambientes estudados. O segundo método consiste na aplicação de questionários aos usuários dos ambientes, para a obtenção de respostas pessoais sobre as sensações térmicas reais. A análise dos resultados mostrou que as zonas de conforto, verificadas na edificação, foram distintas para cada estação do ano em que a pesquisa foi desenvolvida. Pelos votos pessoais, os intervalos de temperaturas de conforto, no outono, foram mais amplos do que os previstos pelas Normas. Entretanto, no inverno, o método normatizado superestimou as faixas de temperaturas de conforto obtidas pelos votos diretos. Os resultados das zonas de conforto térmico foram confrontados com os de outras pesquisas feitas tanto em regiões de clima semelhante ao deste trabalho, quanto em locais de clima mais frio, verificando-se coerência entre os dados. A pesquisa concluiu que, na estação do outono, os ambientes da edificação proporcionaram a seus ocupantes situações de desconforto térmico para o calor na maior parte do tempo, todavia, na estação do inverno, as situações de conforto térmico foram predominantes.

This study try to understand which aspects were fundamental to indoor climate and how to obtain them in order to provide the best possible experience in the thermal comfort of individuals. Thus, arose the studies of Fanger, which was the seed for a new era of discoveries in the area and founded the knowledge our society have today in this globally used standards and norms. Referring to these fundamental aspects of the indoor comfort, data collection was taken in situ to show in details what was happening. This study was executed in order to demonstrate the differences between the data previous and after a process of retrofitting in dwellings built in the 60s and 70s of the century past, in the district of Tjärna Ängar, Borlänge, Sweden. The comparative results using criteria such as Predicted Mean Vote (PMV), Predicted Percentage Dissatisfied (PPD), Draft Rate (DR), air velocity, Mean Radiant Temperature (MRT), Relative Humidity (RH) and air temperature, showed an improvement in 6 of the 8 parameters analyzed. Confirming the expectation that through the retrofitting the residents will be more satisfied, obtain better quality of indoor climate comfort and also increase occupied area in these dwellings.

<p>The research is aimed in order to increase the efficiency and improve the<br />energy performance of multi-level administrative buildings in temperate<br />climate conditions. Special emphasis is on achieving and maintaining<br />acceptable indoor environmental standards and thermal comfort of<br />occupants. The investigation is based on a complex multi-criteria optimization<br />utilizing the most contemporary technology of dynamic energy simulations.<br />The developed methodology for energy performance evaluation and<br />improvement in the function of occupant comfort will have the possibility of<br />application on similar and newly designed buildings. The formulated model<br />also possesses flexibility and adaptability for further improvement and<br />application in different climatic conditions.</p> / <p>Истраживање је усмерено на повећање ефикасности и унапређење енергетских перформанси вишеспратних административних зграда у умереним климатским условима.
