‘SMART Building’ sustainable and hightech

ZENBER Architecten has created a modern, comfortable and inspiring work environment in the MM25. The work environment has an open and transparent character and flexible interior design, which complements the working methods and needs of the organisations. The new head office for Croonwolter & Dros, Mobilis and Servicis is equipped with various work environments, project team rooms, various meeting areas and a multifunctional (work) restaurant.

“Sustainable and high-tech work environment”

intelligent and tech-ready

The office building is tech-ready, meaning it uses localisation sensors and intelligent data infrastructure to collect information from the building’s users, with which the devices in the building can be adjusted to the users’ needs and energy consumption reduced. The technology will also ensure that the rooms in the office building are used more efficiently. In addition, LED lighting, a new energy-efficient heating and air-conditioning system and heat-reflective glass will contribute to a great reduction of energy consumption.
