Clean Urban Energy

Clean Urban Energy, Inc. was a Chicago, Illinois cleantech company that turned large commercial office buildings into grid-scale thermal energy storage assets. Its technology harnessed the existing thermal mass of a building — concrete, drywall, furnishings — by pre-cooling during off-peak hours and coasting through peak demand, effectively operating the building as a multi-megawatt battery for demand response and load shifting without installing dedicated storage hardware. The company raised a reported $7 million venture round and appears in the Battery Ventures list of all portfolio companies. As of a July 2026 review the company has no live corporate web presence: the cleanurbanenergy.com domain no longer serves company content, and no developer portal, API, documentation, or GitHub organization could be located. It is catalogued here as an inactive, non-API-provider company record.

Clean Urban Energy is profiled on the APIs.io network. Tagged areas include Company, Energy, Cleantech, Energy Storage, and Thermal Energy Storage.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/clean-urban-energy: open an issue to ask a question, or submit a pull request to add artifacts.
