Enhancing building performance has become a focal point in reducing the environmental impacts of the built environment to address climate change. Considering the highest share of comfort-related energy use in buildings, and the importance of indoor environmental quality (IEQ), a balance between energy conservation and IEQ provision is required. Building façades are the primary boundary that control mass and energy flow in buildings. Dynamic façades are potential alternatives to existing high-performance façades to improve IEQ in buildings, as they change their functionality with time, in response to changing environmental loads. This study aims to design and develop a multifunctional climate-responsive façade (CRF) in a continental climate. First, the literature review presents CRF theories and technologies. To design the CRF conceptually, a performance-based design framework was developed. This tool can be used in the initial decision-making stage of CRFs to conceptualize them based on case-specific performance metrics. The design of the conceptual CRF was optimized using CFD simulations in the climate of Toronto, Canada. The façade is a multifunctional, integrated, climate-responsive, opaque and ventilated (MICRO-V) façade, which regulates heat, air, and moisture flow into buildings. MICRO-V comprises a pre-conditioned cavity with phase change materials, and an adjustable insulation system integrated with a bi-directional ventilation module with heat recovery. The design of the MICRO-V was finalized by selecting the best-performing configuration of geometry, material properties, and operation. The results showed a 77% pre-conditioning efficiency of air in the ventilation module. Also, the thermal transmittance of the insulation could change from 0.05 to 0.5 W/m2.K with airflow variation. The simulations showed the interactions between the MICRO-V components, leading to the façade prototype. The performance of this prototype was evaluated using experimental tests in the BETOP test cell in Toronto. The results demonstrated the performance of the façade under different operation scenarios, and its ability to pre-condition fresh air while controlling thermal exchanges in the room. The experimental tests confirmed an agreeable compatibility with the simulation results. In this study, a design process from concept generation to prototype development of CRFs was presented that could be expanded and used in future research. MICRO-V is a CRF with decentralized ventilation that could be adjusted to different building contexts and climates.

“…De forma geral, o potencial bioclimático pode ser considerado como a interação do edifício com o lugar em que se insere, bem como as estratégias para a adaptação da arquitetura ao clima. Assim, de acordo com Olgyay (1963), Almusaed (2011 e Kosir (2019), o conceito de potencial bioclimático é frequentemente utilizado para adaptar um edifício às condições climáticas relevantes, utilizando de estratégias bioclimáticas passivas.…”

“…Nesse contexto, para que o projeto bioclimático de edifícios seja eficaz, a adaptação dos edifícios às futuras condições climáticas deve ser considerada, bem como a utilização de estratégias bioclimáticas passivas. Em geral, as estratégias passivas de projeto podem ser divididas em quatro grupos principais de estratégias: retenção de calor, admissão de calor, exclusão de calor e dissipação de calor (KOSIR, 2019). Portanto, a seleção das estratégias deve ser apropriada às características climáticas e localização (SZOKOLAY, 2014;KOSIR, 2019;PAJEK e KOSIR, 2018).…”

As preocupações globais com as condições de conforto térmico devido às mudanças climáticas têm se tornando pauta prioritária do século XXI. Esta pesquisa tem como objetivo a investigação da evolução climática, das estratégias bioclimáticas passivas de projeto, e das horas de conforto e desconforto, utilizando como base a série histórica climática da cidade de São Paulo. A metodologia consiste em elaboração do perfil climático da região de estudo utilizando a série histórica, e análise do potencial bioclimático por meio de estratégias bioclimáticas de projeto, utilizando o software AnalysisBIO. Os resultados apresentam tendências de variações nas amplitudes térmicas, podendo induzir ao estresse térmico por calor dos ocupantes, e as porcentagens de desconforto foram mais frequentes nos anos recentes. A estratégia de sombreamento apresenta maiores valores de horas requeridas em anos mais recentes, apresentando aumento em 3,1 pontos percentual em 2018 em relação a 1989. A investigação das estratégias bioclimáticas de forma evolutiva, apresenta recomendações que deveriam ser aplicadas hoje nos projetos para que as edificações garantam condições de conforto térmico em São Paulo nos próximos anos.

“…Nowadays, the implementation of passive design principles is constantly evolving owing to the development of the related software technology (e.g., orientation, form, openings) [40,41]. Passive design methodology contributes to energy efficiency, the preservation of natural resources, the reduction of environmental pollution, as well as to the improvement of the health of the building' users, hence to all three key aspects of sustainable development: ecological, social and economic, which is the reason behind its implementation worldwide [42][43][44][45][46][47].…”

The fact that people spend a major part of their lifetime indoors, together with the lethal COVID-19 pandemic which caused people to spend even more time inside buildings, has drawn attention to the significance of achieving Agenda 2030 SD goal number three: good health and well-being, in reference to the indoor environment. The research subject is the health and well-being of building users explored through the sustainable (passive) design principles having an impact on the comfort and quality of the indoor environment. It is set within a regenerative sustainability framework encompassing the physiological, biophilic, psychological and social aspects of comfort. The Comfort Assessment Model’s categories, to some extent, rely on the first author’s doctoral thesis, with further modifications regarding the passive design criteria and indicators. A comparative analysis of the model with international sustainability certification (rating) systems has been performed, proving the significance of introducing more passive design comfort (health) related criteria into sustainability assessment models. In addition, a focus group of expert architects contributed to the research conclusions by responding to a questionnaire addressing the issues of sustainability, comfort and passive design, in terms of the health and well-being of building users, which confirmed the relevance of applied passive design measures for providing comfort indoors and fulfilling sustainable development goals.
