# Hammarby Sjöstad, Stockholm — SCD v0.2.3 district research assessment **Date:** October 11, 2026 **Jurisdiction:** Hammarby Sjöstad *district within Stockholm municipality*. It is NOT an incorporated separate municipality. **Result:** **NOT APPLICABLE as a standalone municipal city Type/Autonomy classification**. Not 0A, and not Stockholm 2C. District capabilities reported below. **Status:** Provisional editorial research; no Sites import/publication authorized. ## Core conclusion This is a **material deployed sustainable urban neighborhood** with sizeable automated pneumatic waste collection, waste-heat reuse, district heating/cooling, and wastewater-to-energy coupling. However, **fixed-rule physical automation, resource reuse, and environmental design do not demonstrate Type 2 intelligence or Level C autonomy without specific production evidence**. It is wrong to treat the seller's plans to add AI to waste optimization as already operational, or to apply the entire district's service penetration to the whole City of Stockholm. ## Confirmed district operating deployments - **ENV / automated pneumatic waste:** The Envac operator states approximately **12,700 apartments connected**, **770 waste inlets**, a *designed* throughput of **20 tons/day**, and operating stationary/mobile vacuum waste systems distributed across Hammarby. Those are vendor-reported scale figures, not independently audited current tonnage; the neighborhood service is nevertheless not just a single small pilot. Source SRC-001. - **ENG / district heating and cooling:** Thermal networks receive heat from energy recovery and treated wastewater; solar energy is deployed at selected buildings. This is operating regional/district utility infrastructure, but no N/W municipality-specific adaptive dispatch proven by current sources. SRC-005. - **WAT / wastewater and biogas:** Henriksdal treatment/energy infrastructure is connected to the area's circular resource flows but serves a larger region; whole-facility throughput must not be treated as neighborhood-only deployment. SRC-005,010. - **BLD / building efficiency:** Retrofit efforts are underway with 2030 goals. Local program leaders specifically acknowledge many original building energy-performance goals were missed and maintenance underperformed. Distinguish future aspirational performance from measured operation. SRC-006,007. ## Excluded or unresolved advanced autonomy and intelligence - **Envac ReFlow:** Evidence describes a resident feedback/sorting experiment in a specific housing cooperative, not a deployed district-scale independent operational optimizer. SRC-001,002. - **AI waste collection and data:** The green innovation district describes *development* of the next generation of AI-supported waste optimisation. No documented district-wide production rollout, algorithmic independently selected operations or feedback-loop actuation logs in inspected sources. SRC-003. - **Local microgrid:** Consortium marketing describes a local energy community but lacks active microgrid dispatch/automatic islanding details and a validated asset denominator. Do not presume autonomy C or advanced Type3. SRC-008; PDF SRC-011 not examined. - **Public transport:** District is served by integrated Stockholm transport, but this does not imply whole-municipality autonomous transit or prove Hammarby-exclusive intelligent mobility operation; source gap remains. SRC-004. ## Type and autonomy table interpretation The eight SCD weighted service domains are a **municipality-scale tool**. Hammarby is one district. Its physical local network may be assigned P/D in a Stockholm proper city assessment unless a network actually operates as a materially municipality-serving service at N/W inside Stockholm. Here, `municipal_g=NOT_APPLICABLE` and numeric totals are null — **do not display 0.00 or 0A**. At the **district system capability** level, pneumatic conveyance is a qualifying connected, automated physical service with local Type1-style characteristics; decision authority is **conventional fixed operation, A0 absent stronger evidence**. District heating/wastewater processing is physical infrastructure, not intrinsically higher autonomous intelligence. Additional input/output telemetry, condition-dependent action selection, operator logs, measured feedback, site counts and local user denominators would be required for district-level Type2/C proof. A separate district-specific ranking method, if desired, requires editorial approval, distinct from the 0–100 municipality formula. ## Source audit Twelve candidate URLs; ten source originals examined, two not yet examined, zero blocked in this pass, and six organizational publisher-family labels (some linked affiliates). Several vendor pages are translations or closely related and are **not independent corroboration**. See `source_register.csv` for original URLs, publishers and per-source states. Annual tonnage, current intelligent operational strategy controls, full building-stock retrofits, and district energy autonomy remain source gaps. ## Critical import control If this is included later in a Sites import, **upsert as a district/project of Stockholm**, not a separate city row. Preserve all Stockholm current Type/Autonomy scores and original first-batch assessments; never apply a district's 12,700 serviced apartments as Stockholm municipality coverage or assert that AI-development pilots are production actions.
