A performance-based international initiative revealing the buildings achieving the largest real energy savings and shaping tomorrow's standards.
The World Championship for Energy Savings (WCES) is a global initiative launched with UNEP's Global Alliance for Buildings and Construction.
It identifies and showcases buildings delivering the highest reductions in real energy consumption based on measured data.
No pledges. No simulations. Only results.
Buildings submit real energy data and demonstrate performance improvements over time.
Performance is calculated using a standardized performance methodology. Buildings compete within national leagues or directly at the international level.
Top-performing buildings are showcased globally and awarded at COP.
Benchmark your assets, gain international visibility and position your portfolio among global leaders.
Identify national champions and leverage real-world performance to inform policy.
Access a curated pipeline of high-performing assets and market-leading practices.
Countries endorse the initiative and establish national energy leagues. These leagues identify top-performing buildings domestically and form national delegations competing on the global stage.
Each year, the best-performing buildings worldwide are revealed and recognized at COP, in front of governments, industry leaders and international institutions.
