The main actions implemented to reduce the energy consumption of this building.
Efficiency Investments
- Implementation of an energy sobriety plan starting in June 2022: optimization of HVAC operations (building layout with particularly energy-intensive zoning), shutdown of domestic hot water, standardization of a 19°C setpoint, decommissioning of the event space when not in use, and LED relamping;
- Work on comfort temperatures with tenants (due to strong building inertia and zoning), with supply air set to 21°C to achieve a perceived temperature of 19°C in offices.
Use Sufficiency
- Collaboration between MEL and SEM Métropole teams, with support from CEREMA: building audit conducted by CEREMA (to understand how it operates and identify actions) and assistance with facilitation;
- Implementation of “energy sobriety ambassadors”;
- Organization of events related to energy efficiency (18% participation from startups);
- Involvement of CSR-oriented startups to raise awareness among other employees (2 workshops led by startups);
- Display of energy-saving actions on screens;
- Rollout of the Climate Fresk workshop to startup employees in the building.
