Project characteristics

The Défense Plaza tower illustrates the skills we have provided for our clients in over 70 buildings representing more than 1.75 million m² of rented floor space.

Since 2009, Artelia has been assisting Northwood in supervising and continuously improving the environmental performance of this building.

Artelia helped Northwood achieve the very first HQE® Operation V1 certification in February 2011 (CERTIVEA pilot project).

In 2016, Northwood once again demonstrated its confidence in Artelia by asking it to manage the new HQE Operation V2 certification procedure, which was successfully completed in May 2016.

Following an initial energy audit carried out by Artelia, an energy performance contract was deployed in 2012. This was renewed under supervision by Artelia in 2017, with a new and more ambitious target covering energy consumption, installation efficiency and supplier subscriptions, constituting a commitment in terms of the energy and fluid budget. This commitment was enshrined in the new multi-technique contract for which Artelia supervised the call for tenders in 2017.
