Resumo: | The unsatisfactory thermal performance of buildings belonging to higher education institutions in Brazil cause users discomfort in classrooms and affect student performance. To ensure the well- being to the user, the use of mechanical systems for cooling of environments such as the use of air conditioners is necessary to reduce air temperature indoor, by one hand, and increase the energy expenditure of the building by about 50%, by the other side. This study analyses thermal comfort and energy efficiency in the School of Civil Engineering and Environmental UFG through measurements "in loco" and the perception of the users as well as by computer simulation. The methodology consists of: a) analysis of architectural design; b) lifting climatic summer data on air temperature and humidity within the classroom, and the views of users in three different situations - with open windows and doors and on evaporative air conditioner, open windows and doors and natural ventilation, and windows and doors closed and air conditioning on -; c) treatment of climatic data; d) comparison of the collected results and the perception of the users; e) evaluation thermal energy by computer simulation and prescriptive method of RTQ-C. They interviewed 200 users. About 83.3% of respondents were dissatisfied in the situation with natural ventilation, 68.5% in the situation on evaporative air conditioner and 70.2% in the situation with air conditioning on. Although the results suggest that the situation using air conditioners is the most comfortable, the number of users who feel uncomfortable is very high in all situations, not meeting the levels recommended by the ISO 7730 (2005). |

To ensure the well- being to the user, the use of mechanical systems for cooling of environments such as the use of air conditioners is necessary to reduce air temperature indoor, by one hand, and increase the energy expenditure of the building by about 50%, by the other side. This study analyses thermal comfort and energy efficiency in the School of Civil Engineering and Environmental UFG through measurements "in loco" and the perception of the users as well as by computer simulation. The methodology consists of: a) analysis of architectural design; b) lifting climatic summer data on air temperature and humidity within the classroom, and the views of users in three different situations - with open windows and doors and on evaporative air conditioner, open windows and doors and natural ventilation, and windows and doors closed and air conditioning on -; c) treatment of climatic data; d) comparison of the collected results and the perception of the users; e) evaluation thermal energy by computer simulation and prescriptive method of RTQ-C. They interviewed 200 users. About 83.3% of respondents were dissatisfied in the situation with natural ventilation, 68.5% in the situation on evaporative air conditioner and 70.2% in the situation with air conditioning on. Although the results suggest that the situation using air conditioners is the most comfortable, the number of users who feel uncomfortable is very high in all situations, not meeting the levels recommended by the ISO 7730 (2005).O comportamento térmico insatisfatório de edifícios pertencentes às instituições de ensino superior no Brasil provoca o desconforto das salas de aula, afetando o desempenho dos alunos, bem como elevam o gasto energético da edificação, devido à utilização de sistemas mecânicos para arrefecimento dos ambientes, sendo que o consumo de energia pode aumentar cerca de 50% devido ao uso de aparelhos condicionadores de ar. Este estudo avalia o conforto térmico e a eficiência energética na Escola de Engenharia Civil e Ambiental da UFG, através de medições “in loco” e a percepção dos usuários, bem como por simulação computacional. A metodologia consiste em: a) análise do projeto arquitetônico; b) levantamento de dados climáticos de verão, temperatura do ar e umidade relativa, dentro da sala de aula, e a opinião dos usuários em três diferentes situações - com janelas e portas abertas e climatizador evaporativo ligado, janelas e portas abertas e ventilação natural, e janelas e portas fechadas e com ar condicionado ligado -; c) tratamento dos dados climáticos; d) comparação dos resultados coletados e a percepção dos usuários; e) avaliação termo- energética por simulação computacional e método prescritivo do RTQ-C. Foram entrevistados 200 usuários. Cerca de 83,3% dos entrevistados estavam insatisfeitos na situação com ventilação natural, 68,5% na situação com climatizador evaporativo ligado e 70,2% na situação com ar condicionado ligado. Apesar dos resultados apontarem que a situação utilizando climatizadores é a mais confortável, o número de usuários que se sente desconfortável é muito alto em todas as situações, não atendendo os níveis recomendados pela ISO 7730 (2005).Submitted by Franciele Moreira (francielemoreyra@gmail.com) on 2018-03-01T13:07:14Z No. of bitstreams: 2 Dissertação - Victor Leandro Arantes Chaves - 2016.pdf: 35798905 bytes, checksum: aa006b5b27f11381be02b866455b36da (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2018-03-01T13:17:39Z (GMT) No. of bitstreams: 2 Dissertação - Victor Leandro Arantes Chaves - 2016.pdf: 35798905 bytes, checksum: aa006b5b27f11381be02b866455b36da (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2018-03-01T13:17:39Z (GMT).
