The integration of Information and Communication Technology (ICT) inbuildings aligns with the vision of smart buildings, offering opportunities toenhance operational, energy, and resource efficiencies. However, theenvironmental impacts of ICT in buildings are often overlooked, with variousbarriers limiting their effectiveness and an incomplete understanding of theirpositive and negative effects. This study examines the perspectives ofprofessionals and decision-makers on the environmental implications of ICT inbuildings through semi-structured interviews with eight decision-makers indevelopment and implementation of ICT in buildings. The motivations foradopting ICT systems and the challenges posed by existing technological andmanagement constraints are investigated. The findings indicate thatenvironmental considerations and energy efficiency are usually not primarydrivers for ICT adoption. Instead, property managers prioritize operationalreliability and streamlined management practices. Decisions on technologychoices, such as selecting between wireless and wired systems and determiningdata management strategies, are influenced by functionality, neglectingenvironmental sustainability. Furthermore, lifecycle environmental impacts of ICTsolutions are overlooked, even when these systems are implemented withsustainability purposes. Nevertheless, there is a growing environmentalawareness among stakeholders, fostering an interest in assessing these impacts.Current business models that aim to control the digital ecosystem often limitinteroperability and impede integration with other ICT systems. This studysuggests that developing open system architectures to facilitate interoperabilitycould encourage broader ICT adoption, resulting in both cost savings andenvironmental benefits. Incorporating lifecycle assessment in the decisionmaking process for ICT system configurations would allow for a balancedconsideration of environmental and technical performance, supporting a moresustainable approach to ICT adoption in buildings.
