FESI - Integrated Sustainable Building
FESI, Integrated Sustainable Building, is the first event in Italy dedicated to all the technologies and solutions for integrated buildings
Organized by Messe Frankfurt Italia, FESI will be held at BolognaFiere, in October 2025. It aims to be the point of reference for smart building, offering a complete overview of technological innovations: from building automation to HVAC systems, lighting, security, IoT solutions and electric mobility. The event shows how these technologies integrate for efficient and sustainable management of the buildings of the future.
With the first edition in 2025, it will be an dedicated to intelligent solutions and technologies for buildings.
The Project

The new FESI trade project was born, in collaboration with the main industry associations, looking at the new market prospects for the construction and redevelopment of buildings that is rapidly evolving following the recent European directive.
This directive imposes new energy and environmental standards for buildings, with the aim of reducing carbon emissions and improving energy efficiency by 2030.
Planning and preparation
The event takes place in BolognaFiere which is easily accessible by car, train or bus. The access is from the West Entrance (Piazza della Costituzione, Bologna).
Dates and times: 14-15 October 2025 / 09.30 - 18.00
Entrance is free for all operators in the sector
Organize the visitThe context: Smart and Sustainable Buildings
In recent years, the construction sector has been undergoing a profound transformation, driven by the growing demand for more efficient, connected and sustainable buildings. The integration of advanced technologies such as IoT, automation, intelligent energy systems and electric mobility solutions has revolutionized the way buildings are designed, built and managed. These changes not only respond to the need to reduce environmental impact, but also improve the quality of life and the safety of living and working spaces.
In this context, FESI was born with the aim of responding to a dual need: on the one hand, to promote the spread of innovative technologies for building management; on the other, to provide a platform for discussion for all professionals in the sector. This event aims to be a point of reference for architects, engineers, builders, facility managers and all those who work in the construction world, highlighting the opportunities offered by the integration of new technologies.
