“…Regarding "more complex design and construction", authors such as Rodrigues et al [28], Yang et al [54], Gobbo Jr. et al [33], and Balta-Ozkan et al [63] found that smart buildings, compared to traditional buildings, imply more complex design and construction procedures. These are factors that increase complexity, the need for more changes in the design [28,44,61], the incorporation of a large number of systems in the building [31], the need for systems optimization [36], the lack of understanding of the needs of smart building users [33,56,68], and the need to satisfy specific requirements of both the users and owners of these buildings [28,30,31,57]. Furthermore, the design of privacy solutions for IoT [60] and the absence of a common framework that efficiently integrates IoT aspects with operational-level construction practices increases complexity [39,49]; Apanavičien ė and Shahrabani [13] highlight that the need for scalable and cost-effective solutions adds a challenging component to the overall complexity faced in creating smart buildings.…”
