Abstract [en]

As industries seek to reduce their environmental footprint and improve operational efficiency, the ability to monitor and manage energy consumption has become increasingly critical. In energy-intensive sectors such as manufacturing, especially foundries, achieving meaningful energy savings is often constrained by limited data granularity and fragmented system integration. This thesis investigates how industrial energy data collection systems can be improved without expanding existing metering infrastructure, using Scania’s new foundry as a case study. Through a combination of literature review, interviews with leading Swedish industrial firms, and an assessment of Scania’s current practices, the study identifies common barriers such as poor traceability between meters and energy consumers, and a lack of integration between energy and production infrastructure. A practical methodology was developed to contextualize aggregate energy metering by mapping existing meters to specific machines and equipment through facility documentation. This inventory was integrated with Scania’s maintenance system and tested in the foundry environment. The implementation enabled a more actionable understanding of energy consumption and revealed quantifiable energy waste during non-production periods when analyzing historical aggregated energy consumption. The results demonstrate that enhanced energy transparency and operational insight can be achieved by combining aggregate metering infrastructure with data from facility documentation. Despite the integration barriers encountered, this thesis offers a scalable approach for Scania. For the industry, further validation is needed, but a framework aligned with Lean-principles is provided for others to build upon.

Abstract [sv]

I takt med att industrin strävar efter att minska sitt klimatavtryck och förbättra den operativa effektiviteten blir förmågan att övervaka och hantera energianvändning allt viktigare. Inom energiintensiva sektorer som tillverkning, särskilt gjuterier, begränsas möjligheterna till meningsfulla energibesparingar ofta av bristande datagranularitet och fragmenterad systemintegration. Denna studie undersöker hur insamlingen av energidata i industrin kan förbättras utan att utöka den befintliga mätinfrastrukturen, med Scanias nya gjuteri som fallstudie. Genom en kombination av en litteraturstudie, intervjuer med ledande svenska industriföretag och en analys av Scanias nuvarande arbetssätt identifieras vanliga hinder såsom bristande spårbarhet mellan mätare och energiförbrukare samt avsaknad av integration mellan energioch produktionsinfrastruktur. En praktisk metodologi utvecklades för att kontextualisera aggregerad energidata genom att kartlägga befintliga mätare till specifika maskiner, utrustning och processer genom fastighetens dokumentation. Denna inventering integrerades med Scanias underhållssystem och testades i gjuteriets industriella miljö. Implementeringen möjliggjorde en bättre förståelse av energianvändningen och synliggjorde kvantifierbara energislöserier utanför ordinarie produktionstider vid analysering av historisk aggregerad energikonsumtion. Resultaten visar att förbättrad transparens och operativ insikt kan uppnås genom att kombinera aggregerad mätinfrastruktur med data från fastighetsdokumentation. Trots de integrationshinder som identifierades erbjuder detta examensarbete en skalbar metod för Scania. För industrin i stort krävs vidare validering, men ett ramverk i linje med Lean-principer tillhandahålls som andra kan bygga vidare på.
