Policies similar to BERDO exist in other major cities, including Chicago, New York, San Francisco, and Seattle, each tailored to their unique environmental, economic, and urban landscapes. This project aims to leverage data from these cities to analyze the effectiveness of building emissions policies, uncover trends in energy and carbon use, and identify opportunities for acceleration toward net-zero goals. Key areas of focus include: • Policy Comparison: How do emissions reduction policies in Boston, Chicago, New York, San Francisco, and Seattle differ, and what lessons can be learned from their successes and challenges? • Performance Evaluation: Which cities, building types, or sectors are leading or lagging in emissions reductions, and why? • Trends and Insights: What patterns emerge in building performance, and how do factors like size, age, or function influence emissions levels? • Predictive Analysis: What interventions or strategies could help accelerate progress in cities or building categories falling behind?
