The employment of electrochromic glazing can be a solution to balance circadian lighting and avoid glare. This can be achieved by controlling daylight entering the room and may be useful within the context of highly glazed facades in buildings in hot climates. Nevertheless, the use of this technology is rarely discussed in this context. In this regard, the aim of this study is to investigate the electrochromic glazing for the lighting conditions, including visual and non-visual effects within the luminous context of Brasilia, Brazil. The method consisted of computer simulations of a representative highly glazed non-residential room with the comparison of electrochromic glazing and conventional clear glass. Climate Studio was used to evaluate the visual effects of light for the entire year, and ALFA for the evaluation of melanopic daylight illuminance, vertical illuminance, and melanopic daylight efficacy ratio (mel-DER) in four days, including two solstices and two equinoxes encompassing the beginning of the four seasons. Results for the electrochromic glazing showed a better balance between a minimum threshold of 250 lux of mel-EDI without exceeding 1,500 lux of vertical illuminance in comparison with the clear glass. This was achieved in 33.33% of the hours for the north, against 27.78% of the hours for the east, 29.17% for the west, and 24.72% for the south. For the clear glass, this balance was achieved in only 9.17% of the hours for north, 10.28% for east, 12.22% for west, and 15% for south. Regarding the spectrum, higher results of melanopic daylight efficacy ratio were observed for the clear glass over the four simulated days. The main conclusion was that the electrochromic glazing was capable of providing a better balance between visual and non-visual requirements and can be a suitable solution for highly glazed facades in Brasilia. Nevertheless, particularly for the north orientation, the supply of circadian lighting can be jeopardized when the electrochromic glazing remained at the dark state.

“…To achieve this, a description of the buildings to be targeted by energy policy is required. Previous studies have emphasised the importance of using adequate archetypes to describe the stock [43][44][45][46][47][48][49], therefore a base case building described in a highly cited study was chosen to represent Brazilian dwellings [50,51]. This base case building, shown in Fig.…”

“…Nos galpões industriais brasileiros há pouco ou nenhum planejamento arquitetônico para o condicionamento térmico natural, resultando em temperaturas elevadas que proporcionam condições ambientais acima do limite recomendado para os ocupantes deste tipo de espaço (Tinôco, 2001;Mazon;Silva;Souza, 2006;Geraldi et al, 2022).…”

As avaliações ocupacionais em ambientes laborais se mostram relevantes para a saúde, bem-estar e produtividade dos operários. Neste trabalho, analisa-se por meio de modelagem numérica no EnergyPlus, as condições de exposição ao calor em galpões industriais com fonte interna liberadora de calor para Belo Horizonte/MG, equipados ou não com lanternim (12 modelos: variando-se áreas das aberturas, potência da fonte interna e altura desse dispositivo), a fim de averiguar a conformidade das condições térmicas internas em relação ao limite do Índice de Bulbo Úmido Termômetro de Globo (IBUTG) previsto na NR-15/2021. Os resultados realçaram a relevância do lanternim e dos aparatos de proteção das aberturas na vazão de ar em relação ao aumento das horas em conformidade com o limite de IBUTG. Além disso, constata-se que a fonte interna de calor intensifica o efeito chaminé culminando, portanto, no auxílio da vazão natural do ar interno através do lanternim. Deste modo, obtém-se uma diminuição da temperatura interna em até 5,1°C. Com a correção da altura do lanternim, reduz-se até 3,3°C de IBUTG, resultando, neste caso no valor máximo de 28,5°C para o dia extremo do verão belo-horizontino em apenas 36% das horas do ano acima do IBUTG recomendado. Ressalta-se, como principal contribuição, que se tratando de galpões com fonte de calor, quanto maior a área de saída do ar melhor é a condição térmica interna. Em conclusão, casos semelhantes podem aproveitar as estratégias recomendadas neste estudo para projetar novos galpões ou tomar decisões de intervenção em edifícios existentes.
