Siemens Navigator Alternative | Nectar
Nectar provides deeper utility data management than Siemens Navigator (SiGREEN / Sustainability Navigator) with specialized parsing, broader provider coverage, and faster time-to-value. While Siemens focuses on supply chain carbon footprinting and product lifecycle sustainability, Nectar delivers the granular utility data foundation of automated collection, 99.2% accuracy, and operational analytics that enterprises need for facility-level sustainability management.

Siemens Navigator is closely tied to Siemens’ building automation and metering estate, and that is both its strength and its shape. Where Siemens equipment is installed, the operational analytics are grounded in real-time building data that no bill-based system can see. Global enterprise delivery and support come with it.
Coverage therefore follows the hardware. Sites without Siemens infrastructure (leased offices, small facilities, recent acquisitions, third-party managed buildings) are served by whatever manual or import process fills the gap, which in a global portfolio produces a two-tier dataset.
Nectar starts from the utility account instead: more than 7,000 providers globally, no hardware, no building system dependency, line-item parsing at 99.2% accuracy, and completeness visible across every site whether or not anything is installed there.
Challenge
Supply chain sustainability platforms lack depth in facility-level utility data collection and management.
Solution
Nectar specializes in facility-level utility data: automated collection from 7,000+ providers, line-item parsing, and site-by-site analytics that supply chain tools cannot replicate.
Challenge
Large enterprise sustainability suites require extensive implementation timelines and consulting engagements.
Solution
Nectar deploys in days with automated account discovery. Connect utility portals, verify data completeness, and start analyzing, no multi-month implementation required.
Challenge
Industrial conglomerate tools are designed for manufacturing supply chains, not for managing commercial utility portfolios.
Solution
Nectar is built for commercial and industrial utility portfolio management, serving manufacturing, healthcare, food & beverage, real estate, higher education, and every other industry with utility accounts.
Facility-level collection is a different problem from building telemetry
Building automation answers what equipment did. Utility billing answers what the site was charged, under which tariff, for which metered consumption, with a document behind it. Disclosure, benchmarking, and cost recovery all need the second, and it is not derivable from the first.
That is why the two layers coexist well. Telemetry adds depth on instrumented assets; a bill-based data layer provides the uniform baseline across the whole reporting boundary, including the sites no rollout will reach.
Where Nectar fits
Choose Siemens Navigator where Siemens building automation is installed and operational analytics on that estate is the requirement. Choose Nectar for uniform utility data across the entire reporting boundary: collected from the bill, so no site is left to a manual process.
Frequently asked questions
Does Nectar need building automation or meters installed?
No. Collection works from utility provider accounts, so coverage begins immediately across every site that receives a bill.
Can Nectar feed Siemens Navigator or a similar platform?
Yes, through the API or exports, so the platform reports on complete portfolio data rather than only the instrumented estate.
Is Nectar suitable for industrial and manufacturing sites?
Yes, including steam and process fuel where they appear on utility or supplier billing, alongside electricity, gas, water, and waste.
How long does deployment take?
Weeks for most portfolios, with no implementation project or consulting engagement: the main dependency is obtaining utility account credentials.
