EQWATER and the High Environmental Quality Approach (HQE)

Some of the Eqwater programme's HQE targets:
The quest for highly efficient, easily maintained building systems is a source of future savings.

The building's relationship with its immediate environment:

  • Optimised orientation of spaces according to external constraints (climatic, acoustic)


Energy management:

  • Implementation of highly efficient energy solutions
    • Adjustment of lighting near the façades according to the amount of natural light
    • Use of solar energy to produce domestic hot water

Water management:

  • Implementation of water-saving solutions
    • Recovery of rainwater to water green areas.

Maintenance, sustainability of environmental performance:

  • Building management systems help to simplify maintenance operations, especially for:
    • heating and cooling systems
    • ventilation systems
    • lighting systems

Acoustic comfort:
Ensuring that future users enjoy optimum conditions of hearing and intelligibility, thus improving living and working conditions on the premises.

Visual comfort:
Maintaining satisfactory lighting

  • Window blind systems to guarantee the best compromise between light and heat
  • Optimised proportion of glass surfaces according to the orientation of the façades
