Context

Managing the energy renovation of a public heritage dispersed across several sites requires rigorous coordination: diversity of buildings, annual budget constraints, obligations of transparency and reporting to elected officials.

The system put in place includes an audit of the entire portfolio, the design and execution of work according to priority, and structured performance reporting. A multi-year partnership that transforms a regulatory constraint into a lever for asset management.

Mapping and prioritizing heritage

Multi-site audit — assessment of the potential of each building, prioritization according to ROI and budget constraints.

Manage the implementation site by site

Multi-year coordinated program — planning, site monitoring, performance validation at each delivery.

Reporting to elected officials

Structured reporting — dashboards, savings indicators, alignment with the Tertiary Decree, summaries for management and elected officials.

Managing a program of this scale—multiple sites, several years, and requirements for public transparency—demands a partner who understands the challenges facing a community. The support provided demonstrated this understanding at every stage.
