A Major Energy and Economic Challenge on Both Sides of the Atlantic

Building energy efficiency has become a strategic priority in both Québec and France, where the
real estate sector represents one of the largest sources of energy consumption and a critical lever
for decarbonization. In this context, organizations face increasing regulatory, financial and
operational pressures that make the management and optimization of real estate assets more
complex than ever.

This integrated approach transforms energy efficiency into a tangible driver of performance. It
helps reduce operating costs, improve building resilience and enhance the long-term value of real
estate assets.

In a rapidly evolving market, it also enables organizations to better navigate the risks associated
with inaction, particularly those related to costs, regulatory requirements and asset valuation.
