ABSTRACT
Building Applied Photovoltaics (BAPV) such as Roof-top Solar PV has gained significant attention in recent years for harnessing the untapped potential of renewable energy sources. However, rooftop PV poses hurdles of space restriction and shadowing in densely packed urban residential neighborhoods. This study aims to design and assess the feasibility of an integrated grid-connected Rooftop and Façade Building Integrated Photovoltaic (BIPV) for meeting the energy demand of residential buildings on an academic campus. Three distinctive groups of residential typologies have been investigated in this study, categorized based on built area and occupants' past energy usage. Additionally, the variation in the measured Energy Performance index of the three different residential groups is illustrated to pave the path for the development of a typology-based residential energy benchmarking and labelling system. The Solar PV system has been designed for the maximum household energy demand recorded in CoVID-affected years due to high residential electricity usage in this period. The study showcases that integration of façade BIPV for low-rise residential buildings increases the system energy production to up to 62.5 % based on the utilized surface area for active PV. Furthermore, the Net Zero Energy Building (ZEB) potential for each typology has been achieved by integration of the proposed Solar PV, evaluated as a function of the Energy Performance Index (EPI) and Energy Generation Index (EGI). The designed nominal PV power of the proposed grid-connected plant is 5.6 MW, producing 7182 MWh annually, meeting the maximum residential energy demand in the studied academic campus in CoVID affected year. © 2022 Elsevier B.V.
ABSTRACT
Ongoing global architectural agendas span climate change, energy, a carbon-neutral society, human comfort, COVID-19, social justice, and sustainability. An architecture studio allows architecture students to learn how to solve complicated environmental issues through integrated thinking and a design process. The U.S. Department of Energy’s Solar Decathlon Design Challenge enables them to broaden their analytic perspectives on numerous subjects and strengthen their integrated thinking of environmental impacts, resilience, sustainability, and well-being. However, the unprecedented impact of the global COVID-19 pandemic transformed the physical studio-based design education system into an online-based learning environ-ment. Mandatory social distancing by the global COVID-19 pandemic restricted interactive discussions and face-to-face collaborations for the integrated zero-energy building design process, which requires features of architecture, engineering, market analysis, durability and resilience, embodied environmental quality, integrated per-formance, occupant experience, comfort and environmental quality, energy perfor-mance, and presentation. This study emphasizes the educational effectiveness of virtual design studios as a part of the discourse on architectural pedagogy of zero-energy building (ZEB) design through integrated designs, technological theories, and analytic skills. The survey results of ten contests show educational achievement with over 90% of the highest positive tendency in the categories of embodied environmental quality and comfort and environmental quality, whereas the positive tendency of educational achievement in the categories of integrated performance, energy performance, and presentation were lower than 70%. The reason for the low percentage of simulation utilization and integrated performance was the lack of a proper understanding of and experience with ZEB simulations and evaluations for undergraduate students. Although VDS is not an ideal pedagogical system for the iterative design critique process, it can support the learning of the value of architectural education, including integrative design thinking, problem-solving skills, numerical simulation techniques, and communicable identities through online discussions and feedback during the COVID-19 pandemic. © 2021, College Publishing.
