efa:ON Leipzig

efa:ON is the leading trade fair for electrical, building, and lighting technology in Central Germany. Since its inception in 1990, it has evolved into one of the region’s most important industry gatherings – with influence that extends well beyond its local roots. The event takes place at the modern Leipzig Exhibition Grounds, one of the most advanced trade fair centers in Europe. It impresses with its striking architecture and excellent transport connections. The fair is held every two years in September and is organized by Leipziger Messe GmbH, a seasoned host of international industry events.

efa:ON is laser-focused on current and future challenges in the electrical sector, structured into four themed areas: ON:BUILDING covers intelligent building technology, modern lighting design, automation, and sensor systems; ON:ENERGY focuses on renewable energy, photovoltaics, energy storage, and charging infrastructure for e-mobility; ON:NETWORK addresses issues such as grid stability, data infrastructure, and broadband expansion; ON:DIGITAL showcases digital solutions related to IoT, AI, BIM, and IT security.

Across these themes, manufacturers and service providers present innovative products, system solutions, and applications that not only reflect today’s technological landscape but also offer practical visions for the future of smart construction and energy systems.

A distinctive feature of the fair is its strong connection with the regional economy, professional associations, and educational institutions in Saxony and neighboring federal states. This creates a platform that offers ideal conditions for both mid-sized companies and international market leaders to showcase their innovations to a knowledgeable audience. Visitors range from tradespeople and planners to professionals in energy supply, construction, industry, public administration, and the housing sector.

Another key focus of the event is its comprehensive program of forums, workshops, and special events, which provide hands-on information about new standards, technological trends, and current developments. As such, efa:ON stands not only for innovation, but also for professional exchange, targeted further education, and sustainable knowledge transfer.

The Leipzig Exhibition Grounds offer optimal conditions with their modern infrastructure, spacious halls, and state-of-the-art digital facilities. Thanks to its central location, the venue is easily accessible by car, train, or plane. Set in a city with a vibrant culture of innovation and a rich technical heritage, Leipzig provides an inspiring environment for a trade fair that addresses the present and future of electrical and building technology – practical, forward-looking, and open to dialogue.

On the whole the organisers welcomed on the 3 days of the fair, from 20. September to 22. September 2017, about 213 exhibitors and 12200 visitors on the efa:ON in Leipzig.
