The Standard Energy Efficiency Data (SEED) Platform was developed to help state and local governments address the challenge of implement building performance reporting regulations for private and/or public buildings. SEED provides a flexible, free, secure, and private data platform for managing large datasets. The SEED source code is open source and extensible so that other parties can access the data, and offer add-on tools and services in a replicable way. This paper details the varying processes that had started to emerge in New York City, Seattle, Washington DC, San Francisco, and Austin, and then summarize the features of SEED that were developed to address key challenges. SEED has the potential to significantly decrease the administrative effort required to implement performance-tracking programs and increase the quality of analysis. By aligning data formats and data management processes across jurisdictions, SEED can also help to ease reporting burdens for owners and contractors, facilitate parallel analysis and comparisons between jurisdictions, and increase the availability of products and services that utilize this data. This paper also explores SEED’s potential at scale in the market and the ongoing role for interested users and software developers to contribute resources and provide input on ongoing development.
