SUSTAINABLE FEATURES:

BREEAM, estimated rating: very good.
Energy consumption: approx 50 kw/m2/year

PROJECT DESCRIPTION:

It all started with a vision from the founding family of the wholesale distribution company Magnusson & Freij, to have an office, store and warehouse that would be a state of the art sustainable building and at the same time reduce the energy consumption by 50%. The project Cleen Green was on its way.

The building that previously was an old office and warehouse is now a state of the art sustainable office, store and warehouse.


REFURBISHED BUILDING

When the existing building was purchased it was in a bad shape. Different renovations had been made since the sixties, from the former company Schenker, and needed a total refurbishment to make it possible for M&F to move in. It was early on in the building and design process the project team decided to use the BREEAM tools for the project. The reason was to have a mutual work method for all the different disciplines to share. The building consists of one office of 1000m2, three warehouse halls of 2500m2 and a store of 500m2.
