“…Studies dealing with both the digital and physical models are categorized into two types. They deal with complementarity as an "alternative" aspect [42] or a "synergy" aspect [43,44]. Studies on complementarity as an "alternative" aspect emphasize the fact that the roles of digital models increasingly replace the roles of physical models.…”

In this study, a design methodology based on prototyping is proposed. This design methodology is intended to enhance the functionality of the test, differentiating it from the prototyping that is being conducted in conventional architectural design projects. The objective of this study is to explore reference cases that enable designers to maximize the utilization of both digital models and physical models that have been currently used in architectural designs. Also, it is to explore the complementary roles and effects of digital models and physical models. Smart Building Envelopes (SBEs) are one of challenging topics in architectural design and requires innovative design process included tests and risk management. A conceptual prototyping-based model considering the topic is applied to the design studio (education environment in university). Designing SBEs is not difficult to conceive ideas, but it is impossible to “implement” using the conventional design method. Implementing SBEs requires to strengthen validities and improve responsibilities of ideas in the stages of architectural designs, with cutting-edge technologies and smart materials. The design methodology enables designers (represented by students) to apply materials and manufacturing methods using digital models (parametric design, simulation, BIM) and physical models, rather than representing vanity images that are considered simple science fiction.

“…The data reported from the IEA showed that the total installed production capacity of photovoltaic systems (PV) has grown with an average rate of 49% per year during the last ten years [19], and, similarly, an increment of 12% per year has been registered for solar thermal (ST) plants [20]. Furthermore, the growing interest toward bioclimatic and solar houses is demonstrated by numerous studies on the exploitation of solar irradiation for passive strategies [21][22][23][24][25][26]. The concept of a zero-emission solar house (ZESH) was proposed by Oliveira et al, 2017 [27], who developed the Ekó House ZEB concept, starting from the aforementioned classification proposed by Torcellini et al [8].…”

This work presents a validated workflow based on an algorithm developed in Grasshopper to parametrically control the building’s shape, by maximizing the solar irradiation incident on the building envelope and minimizing the embodied emissions. The algorithm is applied to a zero-emission building concept in Nordic and Mediterranean climate zones. The algorithm enables conducting both energy and environmental assessments through Ladybug tools. The emissions embodied in materials and the solar irradiation incident on the building envelope were estimated in the early design stage. A three-steps optimization process through evolutionary solvers, such as Galapagos (one-objective) and Octopus (multi-objective), has been conducted to shape the most environmentally responsive ZEB model in both climates. The results demonstrated the replicability of the algorithm to optimize the solar irradiation by producing an increment of solar incident irradiation equal to 35% in the Mediterranean area, and to 20% in the Nordic climate. This could contribute to compensate the additional 15% of emissions due to the higher quantities of employed materials in the optimized design. The developed approach, which is based on the parametric design principles for ZEBs, represents a support instrument for designers to develop highly efficient energy solutions in the early design stages.

“…Verification and validation are processes whose subject changes depending on the lifecycle stage they are applied to. It includes methods aimed to capture the customer's voice such as QFD or TRIZ, which aim at designing the ideal product (Pignataro, Lobaccaro and Zani, 2014), as well as the technical and lifecycle requirements arising from understanding and interpreting market needs (Maropoulos and Ceglarek, 2010). Researchers have identified that Requirements Validation proves that the requirements (and hence the system design) should satisfy the customer's need or purpose before the system is actually built (Duren, 2006).…”

“…The key parameter that alters the focus of the method used is the scope of its implementation, whether it's verification of characteristics or validation of the design. As an example some papers used Testing for validation of the product , other papers for Verification of the characteristics (Lan, Arteau and Sirard, 2004;Santini-Bell et al, 2008) and some with a general focus on V&V (Bucca et al, 2009;Pignataro, Lobaccaro and Zani, 2014).…”

This work sets out to provide clarity on the current use of Verification and Validation (V&V) practices across the product's lifecycle and proposes a novel product lifecycle managementbased V&V approach. By systematically analysing the literature, stages, scope, methods and techniques used for V&V were investigated, leading to classification and clustering of the V&V methods or techniques from the product's lifecycle perspective. The analysis revealed that V&V are not currently addressed as lifecycle processes, they are largely absent from the post-production phases and provided insights on how V&V can be applied across the product's lifecycle by proposing a novel Product Lifecycle Management-based (PLM) approach for V&V. This paper is the first to map the 'as is' V&V practices across the product's lifecycle and supports the engineers and academics on how V&V processes can be applied beyond the internal organizational boundaries by developing a PLM based approach for V&V.
