After signing up, every developer is assigned a personal API access key, a unique combination of letters and digits provided to access to our API endpoint. To authenticate with the Energy Audit Automation API simply include your bearer token in the Authorization header.

No long-term commitment. Upgrade, downgrade, or cancel anytime. Free Trial includes up to 50 requests.
Commercial building energy screening: EUI vs EPA national median, carbon emissions, dollar penalty exposure across NYC LL97, Boston BERDO, Denver Energize Denver and Washington DC BEPS, rooftop solar offset, and ranked upgrade roadmap. Every figure traces to a cited regulatory source.
Each endpoint returns specific data related to energy audits for commercial buildings. For example, the Quick Audit endpoint provides estimated EUI, EPA benchmarks, and solar offset summaries, while the Full Audit endpoint delivers detailed EUI, carbon emissions, BPS penalty exposure, and a ranked upgrade roadmap.
Key fields vary by endpoint. For the Quick Audit, important fields include "eui," "benchmark," and "input." The Full Audit includes "eui," "carbon emissions," and "upgrade roadmap." Each field provides insights into energy performance and compliance metrics.
Response data is structured in JSON format, with nested objects for clarity. For instance, the Full Audit response includes "input" for user data, "eui" for energy use metrics, and "benchmark" for comparison against EPA medians, making it easy to parse and utilize.
Parameters vary by endpoint. The Quick Audit requires "property_type," "sq_ft," and "monthly_cost_usd." The Full Audit needs "annual_kwh," "annual_therms," "city," and "grid_region." Users can customize requests by providing relevant values for these parameters.
Data is sourced from reputable references, including the EPA ENERGY STAR Portfolio Manager, NYC LL97 regulations, and municipal codes from Boston and Denver. This ensures the data's reliability and compliance with local laws.
Typical use cases include assessing energy efficiency, compliance with local regulations, and identifying potential upgrades for cost savings. Users can leverage the data to make informed decisions about energy management and sustainability initiatives.
Users can analyze the returned data to benchmark their building's energy performance against national medians. For example, comparing the "your_eui" value to the "national_median" helps identify areas for improvement and potential compliance risks.
Data accuracy is maintained through regular updates from authoritative sources and adherence to regulatory standards. Each figure is traced to a cited source, ensuring transparency and reliability in the information provided.
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process.
