  "raw_analysis": "The High Performance Building Database is a public, government-operated platform developed jointly by the U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL). It serves as a central shared resource for the building industry, aggregating high-performance building case studies. Target users are architects, engineers, building scientists, researchers, and policy makers in the sustainable/green building space. The platform is mature given its institutional backing by DOE/NREL, though its public-facing API surface is not evident from the provided information — it appears to be primarily a web-based database rather than a developer-facing API service. No public REST API, authentication scheme, or documented rate limits are disclosed. Access is presumably free and open given its government origin and public-good mission. Integrations likely exist within the broader DOE/NREL ecosystem (e.g., OpenStudio, EnergyPlus, Building America), but this is not confirmed here. The URL 'https://nrel.gov:building-case-studies' appears to be a pseudo-URL rather than a standard path, suggesting the entry may have been recorded as a service descriptor rather than a programmatically accessible API endpoint."

    "DNS resolution failed for all three checks (website_uptime, robots_txt, llms_txt) — domain could not be reached, so live behavior could not be verified.",
