Caja Madrid Tower

The purchase of the new Caja Madrid headquarters represents a milestone in the Group's commitment to sustainability and the environment.

The new offices were designed with energy efficiency as a priority and feature a number of improvements to reduce their environmental footprint.

Energy efficiency in cooling, heating, lighting and lifts

Climate control

  • The headquarters was built with the best orientation to reduce the intensity of its solar exposure, with the consequent reduction in the energy consumed by air conditioning systems.
  • The AC and heating installations and equipment and their distribution in the building are designed to help optimise variations in the energy demand by services, subsystems and zones.
  • The windows of the facade in office zones are double-paned, so that the temperature of the inner facing of the facade is brought down naturally, optimising the building's cooling system.
  • The tower is equipped with an energy recovery system that captures condensation heat generated on the building's southern facade on sunny winter days and uses it in the heating system for the northern zone.

Lighting

  • The lighting system for the office floors has an integrated control system that permits illuminating only the zones in use.
  • To maximise use of natural sunlight, the lights closest to the facade are fitted with mechanisms that regulate their luminosity according to the availability of sunlight.

Vertical transport (lifts)

  • The building's vertical transport system uses state-of-the-art lift-control technology to maximise efficiency and optimise movements inside the tower. The system records and controls the destination of users in the lift call vestibules and assigns a specific lift to the passenger.

Efficient water management

  • The air conditioning system selected optimises water consumption by switching between using air or water as coolant, depending on the weather conditions.
  • The building's installations are equipped with water economisers.
  • A grease filtering system will be installed to improve the quality of the building's wastewater.

Minimising noise

  • Measures have been taken to minimise the acoustic impact of the building's installations, including soundproofing of machine rooms, installation of silencers and noise abatement facilities.

In 2008 the building underwent an environmental diagnosis.
