The growing incorporation of technology in the construction industry and pressure to reduce energy wastage has led to increasing numbers of buildings utilising smart technology. Smart buildings include analytical tools which can predict the needs of those using the building and monitor parts and systems, flagging them for repair or maintenance. Sensors in a smart building's infrastructure can have a positive effect in terms of reducing energy usage and carbon emissions. However, smart buildings are challenging to design and build, often requiring sophisticated construction techniques and complex mechanical and electrical infrastructure which can lead to claims against the contractor and professional team if they do not meet requirements. Smart buildings are also more at risk from cyberattacks than legacy buildings: a hacker who gains access to a building's system can cause chaos.
