R3 is about scaling the modernization of America's buildings;

Renovate: Change the perspective on buildings by treating them as assets that can be modernized, optimized, and aligned with a building owner’s priorities and goals—partnering with experts and keeping the focus on the organization’s core mission.  

Retrofit: Replace outdated equipment with modern technologies and integrate building systems for peak performance, reliability, and operational efficiency. 

Reduce: Lower the cost of operating facilities while improving performance, comfort, resilience, and the overall building environment. 

Energy Service Companies

As an industry, it is increasingly important to come together to discuss the current state of the energy services industry and where it is headed. R3 provides a forum for critical conversations focused specifically on infrastructure modernization and project delivery—from financing mechanisms and project economics to customer needs and evolving technologies. ESCOs will take back critical information about the market that can guide their strategy development.

Public Sector Agencies

Local and state governments, K–12 schools, higher education, and federal agencies:

  • Facility and operations leaders
  • Energy and sustainability managers
  • Capital planning and project leaders
  • State and local energy officials
  • Procurement and ESPC program managers

R3 provides an opportunity to gain a deeper understanding of the energy services industry, energy savings performance contracting (ESPC), and partnering with Energy Service Companies to modernize aging facilities. Attendees will take back practical knowledge and resources to help their organizations develop and implement successful projects and programs.

Industry Partners

  • Subcontractors
  • Manufacturers
  • Technology providers
