THERMAL COMFORT

The premises heat treatment, for heating and air conditioning, is carried out using micro-perforated 4-tube reversible metal ceilings (cooling and heating distributed by convection), installed in a suspended ceiling on each façade grid. Spaces with intermittent occupancy, such as meeting rooms, are equipped with CO2 sensors to adapt ventilation amounts depending on the number of occupants (25 m3/hour/occupant on average).

SECURITY-SAFETY

SECURITY

4 generators, each with 1250 kvA of power, manage, should there be an urban electricity network power cut, the backup and replacement of all the building s electrical equipment and supplies.

MECHANICAL SMOKE EXTRACTION MODE

(regulatory high-rise building)

FIRE PROTECTION

ACCESS CONTROL AND VIDEO SURVEILLANCE

Precautionary measures for badge readers on the main entry door for office floor spaces and access gates on the landing of each floor; Access control gates in each of the 2 concourses (Courbevoie and La Défense);

Intercom and badge readers on outdoor accesses to the tower;

Intercom, badge readers and automatic umber-plate recognition readers in the car park;

Video surveillance: central safety post with digital video surveillance of accesses, outdoor spaces and car park access.

ENERGY SAVING

Double-flow ventilation of the premises is managed by air handling units with energy recovery, this makes it possible to maintain the temperature of the surrounding air at a low cost. The theoretical occupancy of the premises for calculating air renewal (25 m3/hr/occupant) is 1 person per 10 sqm on the office floor space and 1 person for 2 sqm in areas used as meeting rooms.

TECHNICAL MANAGEMENT OF ENERGY PERFORMANCE (TMEP)

The building has a complete power management system, including: A fully equipped supervisor post; set of electrical, refrigeration and heat energy meters; as well as positive displacement meters;

Fieldbus and cable connections to the metered equipment.

The purpose of the system is to meter the tower s energy consumption per area, usage and type (conventional and unconventional). Metering makes it possible to itemise the conventional lighting, hot water, cold water and domestic hot water consumption by section. It is also possible to itemise unconventional electrical socket and cold water consumption by section.
