Skolfastigheter i Stockholm

What Skolfastigheter i Stockholm does

SISAB (Skolfastigheter i Stockholm AB) is a municipally-owned property company established January 1, 1991, as a wholly-owned subsidiary of Stockholms Stadshus AB within the City of Stockholm corporate group. The company owns, manages, and develops approximately 600 school and preschool properties in Stockholm County, serving roughly 200,000 children, youth, and adults daily through its approximately 260 employees headquartered at Palmfeltsvägen 5 in Johanneshov near Globen. SISAB's portfolio spans approximately 400 preschools (representing nearly two-thirds of property count but only about 12% by area) and roughly 200 primary and secondary schools, including culturally significant standardized "Typförskola" buildings from the 1960s-80s that have received blue classification from Stadsmuseet Stockholm.

The company's operations span the full property lifecycle—from new construction and major renovation to facility management, energy optimization, and security services. Its proprietary SOLIDA AI control system manages heating, ventilation, and indoor climate across 150+ properties covering one million square meters, processing real-time data from thousands of temperature, CO2, and radon sensors using digital twin technology. Supporting systems include GEOFASIT (geographic visualization integrating city geographic data with internal asset data), Antura (project management with two-factor authentication and Masterlistan functionality), SKOL digital key cabinets restricted to ID06-verified contractors, the Driftcentralen real-time climate dashboard, and the Mina sidor tenant portal launched in February 2025. The Energiagenterna program has trained over 16,359 five-year-old preschool children in energy conservation since 2014.

SISAB operates under a single-customer revenue model, generating income through long-term municipal rental agreements with Stockholm's education administration rather than commercial procurement. The company restructured in September 2023, merging its facilities and property management departments into two business areas (preschools and pavilions; primary and secondary schools) to improve coordinated operational delivery. Quantified operational outcomes include a 23% reduction in error reports following SOLIDA deployment, 10% electricity reduction since 2012, and customer satisfaction scores (NKI 84.1% in 2025; service index 83.9% in 2024) running more than 7% above industry averages for community properties.

Scale indicators16 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Skanska: One of the largest construction and project development companies in the Nordics, and an active construction contractor partner for SISAB (collaborating on safety initiatives). Comparable in Swedish scale and overlap with SISAB's construction activities but operates as a private-sector general contractor.
• Castellum: Major Swedish commercial property company with a diversified portfolio across offices, logistics, and public properties. Comparable scale and Swedish footprint but serves private-sector tenants rather than municipal users.
• Vasakronan: Sweden's largest commercial property company, focused on office and retail real estate in major Swedish cities including Stockholm. Comparable in scale and Stockholm real estate footprint but operates in commercial (not public-use) segments.
• NCC: Major Swedish construction and property development company with significant Nordic operations. Overlaps with SISAB's construction and renovation work, though NCC is a private-sector competitor/partner rather than a municipal property operator.

Direct peers

• Specialfastigheter: Swedish state-owned property company that owns and develops special-purpose properties (defense, corrections, cultural heritage). Directly comparable to SISAB as a state-owned single-purpose property manager with a public-sector mandate and long-lease customer base.
• Locum AB: Region Stockholm's municipal property company for healthcare facilities, sister entity to SISAB within the broader Stockholm public-sector portfolio. Operates the same ownership/governance model and facility-management mission but for hospitals and clinics rather than schools.
• Akademiska Hus: Swedish state-owned property company that owns and manages university and higher education properties nationwide. Directly comparable to SISAB in mandate (educational facility ownership) and ownership structure (state-owned), differing only by educational segment (tertiary vs K-12).
• Hemsö: Swedish public-use property company (owned by AP3 pension fund) that owns and develops public properties including schools, healthcare facilities, and municipal buildings across Sweden. Closest structural peer to SISAB, with similar long-lease public-tenant model and portfolio scale.

Regional players

• Stockholmshem: Municipal housing company owned by the City of Stockholm, part of the same Stockholms Stadshus AB group as SISAB. Comparable governance and ownership model, but focused on residential rather than educational properties.

Emerging players

• BrainBox AI: Canadian AI-driven building management company offering autonomous HVAC optimization for commercial real estate. Most relevant emerging peer for SISAB's SOLIDA technology platform — both leverage AI for building energy optimization, though BrainBox AI operates as a SaaS product serving private-sector clients globally.
