On 11 January, the Swiss Federal Office of Energy recognized outstanding energy projects with the Watt d’Or prize. The SEK Mättmi project, featuring the Hybridbox energy center, was a winner. The project, supported by the Umwelt Arena Foundation, has been praised for its innovative approach in energy efficiency.

Since 2006, the Watt d’Or prize has been given annually to highlight exceptional energy solutions. This year, the SEK Mättmi project in Zurich, with its Hybridbox energy center, gained attention. The project, located at the Knonau-Maschwanden-Mettmenstetten secondary school, integrates photovoltaic systems, heat pumps, and a combined heat and power plant. This setup efficiently heats five buildings and an indoor swimming pool in an environmentally friendly manner. The Hybridbox, developed in Eschlikon, Thurgau, controls the system, which can also run on a small amount of biogas or natural gas.

This project achieves significant self-sufficiency, with 54% in heating and 70% in electricity generation over a year. Notably, the Hybridbox technology is also applied in residential buildings and in renovating older buildings.

Roger Balmer, CEO of Hybridbox AG, expressed gratitude for the support from the Umwelt Arena Foundation. Simon Härdi, Managing Director of the Foundation, emphasized their role as a sustainability and energy competence center. He hopes the Watt d’Or will increase public awareness of energy-efficient innovations. Congratulations were extended to Hybridbox AG for their achievement.
