VIECON expands greening and energy-efficiency measures

Environmental and energy-efficiency initiatives at VIECON

Sustainability is gaining importance across the event industry. At VIECON, it is not just an aspiration but an ongoing development process that is visible across the grounds. Numerous initiatives ensure that the venue remains supported by ongoing environmental improvement initiatives while offering a pleasant environment for guests, partners, and employees.

Green courtyards: New spaces for well‑being in an urban setting

The courtyards at VIECON have undergone extensive revitalization at the end of 2025. Overgrown areas have been transformed into structured, low‑maintenance green spaces with shrubs and perennials. These redesigned courtyards can contribute to improving the local microclimate, create natural shade, and offer inviting areas for visitors and employees — part of the venue's environmental improvement programme.

Vertical greening: Hall A grows upward

The new green façade on Hall A is another visible milestone. Twenty‑six planters with a total of 78 climbing plants will gradually transform the hall’s exterior wall into a vertical green space. This can contribute to cooling through shading effects, plants absorb CO₂ during growth, and enhances VIECON as an attractive, venue with additional greening initiatives.

Green electricity & modern lighting: Energy efficiency in focus

VIECON is also taking decisive steps in its energy strategy. The entire site is now powered 100% by green electricity from hydropower (according to the energy supplier's supply contract). This shift changes the calculated electricity-related emissions compared with the previous supply mix (according to the 2023 energy balance) and ensures that all events take place on a electricity supplied from documented hydropower sources.

At the same time, the entire venue — except for Hall D — has been converted to energy‑efficient LED lighting. LED lighting typically requires less electricity than comparable conventional systems, have a longer lifespan, and notably reduce energy demand during daily operations.

Commitment to global climate targets: Net Zero Carbon Event Pledge

Beyond construction and implementation of environmental initiatives, VIECON is also demonstrating strategic responsibility. By signing the Net Zero Carbon Event Pledge, the venue commits to transparently measuring emissions, actively reducing them, and reporting progress regularly. VIECON has signed the Net Zero Carbon Event Pledge and reports on emission-reduction measures.

Sustainability in detail: From recycling mats to the Christmas tree

Many smaller steps further support the environmental and energy-efficiency initiatives. The new GreenMats in the entrance areas are made from recycled PET bottles, reduce water consumption during cleaning, and lower CO₂ emissions.

Seasonal decisions are also made consciously: In 2025, a regional potted Christmas tree was placed in the reception area. The tree is cared for after the season, reducing waste and enabling multiple years of use.

Conclusion: A venue that takes responsibility

VIECON shows how diverse sustainability can be — from green façades and biodiversity projects to strategic climate commitments. Step by step, a venue is emerging that combines ecological responsibility with urban quality of life, making a contribution to the further development of environmental measures at the venue.
