Tracking Incremental Energy Efficiency Investments in Certified Green Buildings

The briefing introduces an 'energy efficiency cost premium' method to isolate energy efficiency spending from total construction costs in green-certified buildings. Analyzing over 16,000 certifications from 2019-2020, it finds that incremental energy efficiency investments averaged USD 10.5 billion annually, representing only about 5% of the total cost of those buildings. The report highlights that green certifications are inconsistent indicators of energy performance, with over half of tracked assets achieving less than a 30% efficiency gain. It argues that current certifications often fail to align with 1.5°C or 2°C decarbonization pathways and recommends standardized asset-level reporting and a shift toward certifying retrofits in developed economies.

• Incremental investments in energy efficiency for new certified green buildings averaged USD 10.5 billion annually during 2019-2020, which is approximately 5% of the total construction costs for those specific buildings.
• There is a vast disparity between total building construction spending and specific energy efficiency gains; for every USD 1 invested in energy efficiency, USD 19 was spent on conventional construction.
• Green building certifications are unreliable benchmarks for energy performance, as more than 50% of the certified floor area tracked showed an incremental energy efficiency gain of less than 30%, and only 25% achieved gains exceeding 40%.
• Energy efficiency investments in certified green buildings are heavily concentrated in Europe, North America, and Asia, which together account for 97% of the financial flows.
• Green certifications do not guarantee alignment with low-carbon trajectories because their standards are typically not derived from low-carbon scenarios or local decarbonization strategies.
• The vast majority of green certifications are issued for new constructions rather than retrofits; only 4% of the tracked certified floor area corresponded to retrofitted buildings.
• Current green building rating systems generally fail to include the mitigation of lifecycle emissions, focusing instead on the operating phase where at least 80% of lifecycle energy is consumed.
