In which project is the concept of 'intelligent city' mentioned?

The concept of an 'intelligent city' is primarily associated with Filinvest Corporate City. This project embodies the principles of smart urban planning and development by integrating advanced technology and sustainable practices into its design and operations. Filinvest Corporate City aims to create a vibrant mixed-use development that incorporates features such as smart infrastructure, efficient energy use, and enhanced connectivity. This aligns with the notion of an intelligent city, where data and technology are used to improve the quality of life for residents and businesses.

In contrast, the other projects listed do not emphasize the intelligent city concept to the same extent. Philamlife Homes is more focused on residential development without the broader smart city considerations. Bagong Lipunan Sites and Services was designed primarily within the context of socialized housing, and Bonifacio Global City, while modern and developed, does not specifically highlight its identity as an intelligent city in the way that Filinvest Corporate City does. Hence, Filinvest Corporate City stands out as the correct answer due to its alignment with innovative urban development principles that define intelligent cities.
