“…The teachers' and students' perceptions of luminous environmental comfort were ascertained using a questionnaire adapted to the needs of each group investigated (GEMELLI, 2009;OCHOA, 2012). The questionnaire administered to the students, according to age, was of the closed type, and the interviews with the teachers were of the open type.…”

The objective of this article was to evaluate the light conditions in classrooms at a school in the northeast of Brazil and their influence on learning. The illuminance of the rooms was evaluated during solstices and equinoxes. We used NBR 15215-04 and measured light a 16 points using a digital lux meter. Also, perceptions of luminous comfort were ascertained through a questionnaire administered to teachers and students. Only 18% of the evaluated points were within the range of luminosity considered adequate according to the NBR, and the perceptions of teachers and students coincided with the technical results, as the light levels were considered unsatisfactory. According to the teachers, poor lighting affects school activities and the behavior of students, and we recorded complaints of visual discomfort and headaches. The lighting in the evaluated rooms was not adequate in terms of the comfort and quality of student learning. Low-cost strategies aimed at improving visual comfort-and, consequently, student learning-are suggested.

“…From the design perspective, every decision has a great influence on a building's thermal and energy performance, which means that the built environment's satisfactory performance may be achieved through an adequate architecture design project. 5 Brazil has some energy performance public standards and regulations for buildings. The NBR 15.220 6 determines the minimum envelope requirements and presents the Brazilian bioclimatic zones (BZ) with specific constructive guidelines for each of the eight regions.…”

The standard Brazilian school projects (EMEIs) were created for the Proinfância [Pro-Childhood] program to respond to the growing national demand for public schools. Unfortunately, the project disregards the Brazilian local climate, leading to an inadequate architectural design, especially in terms of energy performance. Within this context, this research aimed to assess the impact of a new geometric design and envelope proposal on the energy performance of a Brazilian school building. The study object is a standard project (EMEI) of the Proinfância program located in Pelotas, Brazil. Two distinct multi-objective optimizations were performed based on EnergyPlus coupled with the Strength Pareto Evolutionary Algorithm 2 (SPEA2), in which the objective functions were defined to minimize heating and cooling Energy Use Intensity (EUI) for different geometric designs (Base and Linear models). The design variables considered were window-to-wall ratio (WWR); thermal insulation thickness for walls and floor; solar absorptance values for walls and roof; and solar orientation. A total of 74.520 simulations were carried out, and the results indicated that the new geometric design combined with bioclimatic envelope strategies was capable of reducing 52% of the Energy Use Intensity when compared to the standard school project.

A principal função da edificação é propiciar aos seus usuários proteção e conforto para o desenvolvimento de suas atividades e, no espaço de atividades escolares, o desenvolvimento escolar de um aluno pode ser influenciado pelas condições do ambiente em que se insere. Assim, este estudo avaliou o conforto térmico de uma sala de informática da Escola de Arquitetura e Urbanismo e Design da UFMG - Universidade Federal de Minas Gerais. A metodologia para a análise do conforto térmico consistiu em: a) aplicação de questionário para 46 alunos e, b) simulação computacional para a verificação das horas de conforto no ambiente. Os resultados obtidos no estudo indicam insatisfação do usuário quanto ao conforto térmico no verão e satisfação no inverno. Enquanto no inverno esta sensação foi referendada pela simulação, no verão a indicação de que há desconforto apenas 25% do tempo pareceu subestimar a sensação térmica dos usuários do espaço. No entanto, o fato de o questionário ter sido aplicado no inverno pode ter influenciado os resultados .
