Frequently Asked Questions
Dac vs Nectar Energy: which should you choose?
For commercial real estate owners and facility managers targeting carbon reduction and automated HVAC/lighting control, Nectar Energy is the clear choice with its BMS integration and new ESG reporting. But if your team is data engineering-focused and needs code-reviewed, version-controlled dashboards with AI agent compatibility, DAC offers a unique, developer-first approach at a freemium price point. Your decision hinges on whether your problem is physical building optimization or dashboard creation from SQL data.
Does Nectar Energy work with my existing building management system?
Nectar integrates with BACnet, Modbus, and BMS from Honeywell, Siemens, and Johnson Controls. If your system supports these protocols, it likely works.
Can DAC be used by non-technical users?
DAC requires defining dashboards in YAML or TSX, so it is not suitable for non-technical users who need a GUI builder. It is designed for data engineers and analysts comfortable with code.
Is there a free tier for DAC?
Yes, DAC is freemium. The free tier includes core features like dashboard definition and rendering. Details on paid limits are available on their pricing page.
Does Nectar Energy help with ESG reporting?
Yes, Nectar launched an enhanced ESG reporting module in May 2026 that automates compliance with GRESB, CDP, and other frameworks.
What databases does DAC support?
DAC supports Postgres, MySQL, Snowflake, BigQuery, Redshift, Databricks, ClickHouse, DuckDB, Amazon S3, MongoDB, Elasticsearch, and CrateDB.
Can Nectar Energy control lighting and HVAC separately?
Yes, Nectar offers automated HVAC control based on occupancy and weather, and separate automated lighting control scheduling.
Is DAC suitable for real-time streaming dashboards?
No, DAC is not designed for real-time streaming. It executes queries against static data sources and supports live reload on file save, but not streaming.
Does Nectar Energy require specific IoT sensors?
Nectar integrates with IoT sensors from Honeywell, Siemens, and Johnson Controls, but does not require proprietary sensors if your BMS already collects the necessary data.
