I moderne tekniske bygninger er installationer, CTS og tekniske systemer tæt integrerede og afhængige af hinanden for at fungere stabilt i praksis.
Det stiller høje krav til commissioning, koordinering og teknisk idriftsættelse, hvor grænseflader mellem fag, systemer og entrepriser skal fungere samlet – ikke hver for sig.
Hos Sirius Energy arbejder vi med funktionsafprøvning, systemintegration og kvalitetssikring af komplekse bygninger, hvor selv mindre afvigelser kan få stor betydning for drift, stabilitet og bygningens samlede performance.
Modern buildings depend on increasingly complex technical systems working together reliably in practice. HVAC, electrical systems, controls and other MEP installations must function as one integrated solution — not as isolated components.
This increases the need for strong commissioning management, coordination, documentation and functional verification throughout the project. Sirius Energy supports this transition from construction to operation through hands-on building commissioning and technical quality assurance.

FAQ - BUILDING COMMISSIONING SERVICES
What is building commissioning, and why does it matter?
Building commissioning is the process of verifying that technical building systems - including HVAC, electrical, controls and other MEP installations - are installed, tested and operating as intended before handover.
Effective commissioning helps identify integration issues, functional deviations and performance problems early in the project, reducing operational risk and improving long-term reliability.
At Sirius Energy, commissioning is a hands-on process focused on ensuring systems function reliably in real operation - not only on paper.
What does pre-commissioning involve, and when should it start?
Pre-commissioning includes the planning, inspections, documentation reviews and system checks performed before technical systems are energized or brought into operation. The process typically begins during the design or procurement phase and establishes the commissioning strategy, testing procedures and coordination framework for the project. Early involvement helps identify integration risks, align technical documentation and reduce delays during testing, verification and final handover.
How does commissioning management work across a large or complex project?
Commissioning management coordinates commissioning activities across technical disciplines, contractors and building systems throughout the project lifecycle. This includes maintaining the commissioning plan, tracking testing and verification activities, managing deviations and supporting coordination between contractors, consultants and project management teams. As an independent commissioning partner, Sirius Energy provides transparent technical oversight focused on ensuring systems are fully tested, documented and operational before handover.
What types of buildings does the FACILITY department work with?
The FACILITY department at Sirius Energy works with technically complex buildings where reliable operation of mechanical, electrical and building automation systems is critical. Our experience includes laboratories, cleanrooms, pharmaceutical facilities, advanced production environments, universities and other buildings with high MEP coordination and commissioning requirements. We specialize in projects where functional testing, system integration and operational reliability are essential before handover.
How does commissioning contribute to quality assurance on construction projects?
Commissioning strengthens quality assurance by verifying that technical systems not only comply with project specifications, but also function reliably under real operating conditions. The process includes structured functional testing, system verification, deviation tracking and documented performance validation throughout the project lifecycle. This creates a transparent and auditable foundation that supports both the building owner and project team during handover and operation.
What is re-commissioning, and when is it relevant?
Re-commissioning is the process of re-evaluating and optimizing existing building systems to restore performance, improve reliability and verify that systems continue to operate as intended over time. It is often relevant after renovations, operational changes, system upgrades or when buildings experience recurring alarms, comfort issues or increasing energy consumption. Sirius Energy supports re-commissioning through functional testing, system verification and hands-on troubleshooting of technical building and MEP systems.
Does Sirius Energy work according to DS 3090?
Yes. Sirius Energy applies the principles of DS 3090 as part of our commissioning approach for complex buildings and technical installations. We use the standard as a structured framework for planning, coordination, functional testing and system verification throughout the project lifecycle. At the same time, we combine DS 3090 with practical on-site experience and modern commissioning practices to support today’s highly integrated building and MEP systems.
Hvad er re-commissioning, og hvornår er det relevant?
Re-commissioning er processen, hvor eksisterende bygningers tekniske systemer bliver genvurderet, testet og optimeret for at genskabe funktion, driftssikkerhed og stabil performance over tid. Re-commissioning er ofte relevant efter ombygninger, ændringer i drift, opgraderinger af tekniske systemer eller ved tilbagevendende alarmer, komfort problemer og stigende energiforbrug. Sirius Energy arbejder med re-commissioning gennem systemtest, funktionsverificering og praktisk fejlsøgning på tekniske installationer, CTS og MEP-systemer.
Arbejder Sirius Energy efter DS 3090?
Ja, Sirius Energy kan arbejde efter principperne i DS 3090 i forbindelse med commissioning af komplekse bygninger og tekniske installationer. I mange projekter anvender vi DS 3090 som udgangspunkt for planlægning, koordinering, funktionsafprøvning og systemverificering gennem projektets forskellige faser. Samtidig tilpasser vi altid commissioning processen til det konkrete projekt, bygningens kompleksitet og kundens behov. Vores tilgang kombinerer struktureret commissioning med praktisk erfaring fra on-site commissioning, teknisk idriftsættelse og moderne integrerede bygninger og systemer.
