EFFICIENT HOUSING

MORE ENERGY-EFFICIENT, LOW-CARBON AND HEALTHIER HOUSING

In order to offer its individual clients resource-efficient buildings, Nexity is working on improving the intrinsic performance of its buildings (including thermal performance, carbon emissions and health-friendliness) and focuses its work on:

  • reducing the greenhouse gas emissions of its property developments (in the design and operations phases)
  • managing their energy dependency and associated costs;
  • designing a range of sustainable homes with lower energy consumption;
  • selecting materials and equipment that help ensure better indoor air quality;
  • developing less carbon-intensive mobility solutions associated with the residency.
 

Energy-efficient and low-carbon buildings

Nexity is taking-part in national E+C- (Energy+ Carbone-) accreditation experiments to anticipate the future environmental regulations governing new construction projects, which will replace the current RT 2012 regulations in 2020. Nexity wants to make an active contribution to combating climate change by means of two main initiatives:

  1. Improvements in building energy performance and supporting the move towards positive energy buildings;
  2. Rollout of buildings with a low carbon footprint throughout their life cycle, from design to demolition.

GHG emissions assessment expanded to all new residential developments contributes to achieve these objectives.

This commitment is also translated by solutions development:

  • Access Design product is based on a construction method that uses both wood and concrete;
  • Energy renovation of condominium properties. In 2018, some 15 condominium properties have already been renovated and some 100 buildings stated their interest, of which around 30 have requested project management assistance or are under renovation. 

Moreover, our operations are carried out within a framework of certification and labelling voluntary process. In 2018, 42 development operations (2.357 plots) obtained NF Habitat HQETM certification from Cerqual.

 

Healthier buildings

To improve the comfort of building occupants, Nexity has launched an experimental approach “Healthier Buildings”, including a design guide and a feedback programme. The approach is structured around three key priorities:

  1. Indoor air quality (choice of materials, analysis of the ventilation system);
  2. Living in comfort (interior space design, acoustics, natural light, temperature and humidity); and
  3. Water quality (amenities, supply, etc.).

In addition, the Group has continued its work on integrating health criteria into the specifications given to suppliers, such as by requiring certified materials, environmental certifications, the absence of CMR (carcinogenic, mutagenic and reprotoxic) substances, formaldehyde-free status and natural wood treatments. Thanks to this commitment, the average rating of certified materials for these products is A+.

 

Use of energy from renewable sources

For eco-design buildings, Nexity always considers the use of renewable energies such as solar panels and connections to urban utility grids consisting of a significant proportion of renewable energy (over 60%) to produce domestic hot water, electricity and so on. In 2018, 31% of developments delivered included solar energy for heating or solar panel systems for electricity.
