Environmental features

  • Existing structure and facade conservation
  • Thermographic survey to prevent air leakage paths through the existing fabric
  • Control and review of all roof terrace insulation and waterproofing
  • Thermal evaluation and optimisation of the existing building under the national building regulation
  • Replacement of the historical traditional cooling production by a geothermal system
  • Replacement of all luminaries to reduce power installation
  • Implementation of photovoltaic panels, solar thermal panels for hot water production, 2 wind turbines and urban solar lightings.
  • Life cycle cost analysis for design decisions
  • Adaptation of the lighting zones and thermal zoning of the tenant organisation
  • Adaptation of the ventilation rates and the HVAC systems to ensure maximum indoor air quality
  • Choice of low VOC emission finishing and VOC measurements campaign in progress
  • Acoustic survey of the building and review of all acoustic bridges to ensure maximum user comfort
  • Preservation of the gardens during refurbishment works
  • Enhancement of the landscape with an ecologist survey (planting terrace, flower meadows)
  • Implementation of a landscape management plan
  • Implementation of cycle racks and amenities for building users
  • Close commissioning management throughout the three construction works periods
  • Work on the building user guide with the tenant and publication through the building website
  • Implementation of an on-site sustainable water treatment and reuse of the treated water within the toilets
  • Leak detection system and sanitary supply shut off valves implemented on all toilet blocks
  • Replacement of the BMS to a more developed and adapted one for the building
  • Review of the waste storage locations and implementation of a composting device

Michel Janet, Managing Director NV France says: 

“BREEAM certification is a requisite to keep our properties competitive and sustainable whilst ensuring the durability of the tenant in the premises.”

Building services

  • Cooling production is provided through two geothermal heat pumps which dispatch into the building through a cooled water loop.
  • The heating system relies on convector supplied with grid electricity controlled through the BMS.
  • Fresh air rate of over 36m3/h/occ is provided through air conditioning centrals (CTA) into the offices, connected with CO2 detectors.
  • Electricity generated with 400 m² solar panels and 2 urban wind turbines.
  • Solar thermal panels save energy for the hot water system connected to restaurants.

Green strategy

  • Replacement of the two air to air heat installed on terrace by two geothermal heat pumps.
  • Refrigerant detection system on the geothermal heat pumps technical local.
  • Additional thermal isolation on the roof.
  • 400 m² photovoltaic panels.
  • 60 m² solar thermal panels for hot water production.
  • 2 urban wind turbines.
  • Green roofing with sebum helping rainwater run-off and thermal isolation
  • Rainwater recycling system for irrigation and toilets
  • Sink water treatment recycling for toilets

Damien Liot, Techincal Director, Wereldhave NV France says:

“Wereldhave chose BREEAM because of its international exposure and to evaluate our worldwide portfolio on the same basis.”
