Why Organizations Choose ATEK Over Siemens Desigo
Siemens Desigo has built a reputation as the world’s leading building management system for medium to large facilities. However, organizations in regulated industries—pharmaceuticals, biotech, hospitals, and research—face a fundamental mismatch: Desigo is optimized for building operations (HVAC, lighting, energy), not compliance monitoring. For organizations that need both, ATEK provides a complementary solution that deepens compliance capabilities without replacing the BMS.
Understanding Siemens Desigo
Founded in 1847 and headquartered in Zug, Switzerland (Siemens Smart Infrastructure) and Munich, Germany (Siemens AG overall), Siemens brings global scale to building technologies. Siemens AG operates with $100B+ in annual revenue across industrial automation, building technologies, and infrastructure.
Desigo CC is their flagship building management system for medium to large facilities. It delivers:
- Integrated HVAC, lighting, security, fire safety, and power control
- Energy optimization algorithms and facility-wide automation
- BACnet native support with next-gen PXC4/PXC5 controllers and BACnet Secure Connect
- Multi-discipline dashboard for facilities managers
- OPC, Modbus, SNMP protocol support meeting B-AWS BACnet profile
Desigo CC Compact Validated Monitoring is an optional pharma/cleanroom module that adds:
- 21 CFR Part 11 and GMP Annex 11 validation features
- Room pressurization and fume hood control for labs/cleanrooms (BACnet/IP)
- Validated objects, audit trail, and access security
- Compliance-ready for small-medium pharma facilities
However, this module requires integration partners (e.g., KeyPlants with Safety PLC) for comprehensive compliance, and compliance remains subordinate to Desigo’s core BMS purpose.
Siemens Desigo’s recognized strengths include:
- Global Scale and Integration — Siemens’ worldwide presence ensures broad integration capabilities with building infrastructure and multiple vendor ecosystems.
- Advanced Building Automation — Comprehensive HVAC, lighting, security, and facility control with sophisticated algorithms for energy optimization across enterprise facilities.
- Desigo CC Compact Validated Monitoring — Optional module adds validated monitoring with 21 CFR Part 11 and GMP Annex 11 support for pharma cleanrooms and labs.
- BACnet Protocol Leadership — Native BACnet, BACnet Secure Connect, OPC support via next-generation PXC4/PXC5 controllers.
Common Challenges with Siemens Desigo
Organizations evaluating or currently using Siemens Desigo frequently encounter these considerations:
Design Mismatch: Desigo CC is a building operations tool. Compliance monitoring is an optional add-on. This creates architectural and operational friction—your BMS vendor becomes responsible for regulatory monitoring without it being their core competency.
Compliance Limitations: Desigo CC Compact requires external integrators to achieve deep compliance. You’re coordinating multiple vendors for a single regulatory requirement.
Support Timing: Siemens Smart Infrastructure HQ is in Switzerland. When a critical excursion occurs at 2 AM Eastern Time, their support team is asleep. You’re waiting 6-9 hours for initial response.
Implementation Complexity: Desigo deployments are enterprise BMS projects spanning months. You need certified integrators, on-site IT infrastructure, specialized training, and extensive configuration. Simple compliance monitoring doesn’t require this overhead.
Total Cost of Ownership: Significant upfront hardware (controllers, servers, site work), integrator professional services, software licensing, annual maintenance, and separate compliance modules add up to $250K–$2M+ for typical deployments.
Data Residency: Siemens infrastructure is primarily European. Canadian facilities may face data residency and PIPEDA compliance questions.
How ATEK Addresses These Needs
ATEK’s approach centers on compliance-first architecture, validation without extra work, BACnet integration ready, and rapid pharma/biotech deployment, delivering measurable improvements across critical operational areas:
Compliance-First Design: Unlike a BMS adapted for monitoring, ATEK was built from day one for regulated environments. FDA 21 CFR Part 11, ALCOA+ data integrity, and automatic compliance workflows are core features—not bolt-on modules.
BACnet Integration with Desigo: ATEK doesn’t replace your Siemens BMS. Instead, ATEK deploys alongside Desigo via standard BACnet protocol. Desigo continues managing building operations (HVAC, lighting, energy). ATEK handles compliance monitoring (temperature, humidity, pressure, audit trails). One platform for operations, one for compliance. No vendor confusion, no architectural mismatch.
24/7 Live Support with 5-Minute Response: When a critical excursion occurs at 2 AM, ATEK’s Montreal-based compliance team answers the phone—guaranteed. No automated phone systems, no ticket queues, no next-business-day callbacks.
Real-Time Monitoring: 30-second data updates provide continuous visibility into your environment. Six months of local data storage ensures zero data loss during network outages.
A2LA-Accredited Calibration Lab: ATEK’s in-house A2LA-accredited calibration lab handles calibration, certificates, and traceability documentation in one place. No third-party calibration costs or customs delays for Canadian facilities.
All-Inclusive Pricing: Per-monitoring-point pricing with unlimited users, sites, training, and 24/7 support included. No surprise compliance module fees, no integrator add-ons, no annual escalations.
The BMS + Compliance Monitoring Strategy
Many organizations operate their most critical environments with a two-platform approach:
- Platform 1 (Desigo CC): Building operations—HVAC, lighting, energy, security, fire safety
- Platform 2 (ATEK): Compliance monitoring—environmental data, audit trails, regulated reports, 21 CFR Part 11
This separation of concerns has distinct advantages:
- Operational Clarity: Your facilities team manages building systems independently from your compliance team’s monitoring needs
- Technology Specialization: Desigo experts don’t need to become compliance specialists, and vice versa
- Regulatory Independence: Your compliance system doesn’t depend on building automation changes; your BMS doesn’t require compliance certification
- Cost Efficiency: You scale each platform independently—add more sensors without re-licensing the entire BMS
- Risk Mitigation: Compliance monitoring remains separate from operational systems that control building safety

Frequently Asked Questions
Does ATEK replace Siemens Desigo?
No. ATEK and Desigo serve different purposes:
- Desigo: Controls building systems (HVAC, lighting, energy, security)
- ATEK: Monitors compliance-critical environments (temperature, humidity, pressure, audit trails)
Many organizations operate both platforms in parallel. Desigo manages operations, ATEK ensures regulatory compliance. They communicate via BACnet.
Can ATEK integrate with Desigo via BACnet?
Yes. ATEK supports BACnet protocol and can be configured to:
- Read sensor data from Desigo controllers
- Trigger BACnet events for critical alerts
- Share validated monitoring data with your BMS
- Maintain separate compliance-specific audit trails
Your Siemens integrator can configure the BACnet mapping during deployment.
Do we need to replace Desigo to use ATEK?
Absolutely not. ATEK is designed to work alongside Desigo. Many customers keep Desigo unchanged and add ATEK purely for compliance monitoring. There’s no conflict between the systems.
What if we’re currently using Desigo CC Compact Validated Monitoring?
Desigo CC Compact adds some compliance features, but compliance remains an add-on to a building operations platform. Many organizations find that purpose-built compliance monitoring (ATEK) provides:
- Better audit trails and regulatory alignment
- Faster validation and documentation
- 24/7 compliance-specific support (not general BMS support)
- Lower cost per monitoring point
- Easier scaling to multiple facilities
You can run both during a transition period, then evaluate whether Desigo’s compliance module is still needed.
Is ATEK data stored in Canada?
Yes. ATEK cloud infrastructure is hosted in Canada with PIPEDA, FIPPA, and provincial privacy compliance built-in. Your monitoring data never leaves Canadian jurisdiction unless you explicitly configure it otherwise.
How long does it take to deploy ATEK if we have Desigo?
Typically 1–2 weeks:
- Week 1: Hardware deployment, sensor placement, BACnet integration testing
- Week 2: IQ/OQ/PQ validation, compliance workflow testing, team training
- Day 1 of Week 3: Go-live with 24/7 support
Compare this to months for new Desigo BMS implementations.
Do I need to hire a systems integrator to set up ATEK?
For simple deployments (single facility, fewer than 10 monitoring points), no. ATEK’s cloud platform is self-service.
For BACnet integration with Desigo, we can either:
- Provide integration documentation and assist your existing Siemens integrator
- Engage our own integration partners who specialize in BACnet configurations
- Provide direct support (ATEK team has BACnet expertise)
Most deployments don’t require a separate integrator.
What’s the cost difference between Desigo Compact and ATEK?
Desigo CC Compact: Quote-based pricing (typically $15K–$50K+ per facility for the compliance module, plus controllers, licensing, integrator services)
ATEK: Per-monitoring-point SaaS pricing (typically $200–$500/point/month all-inclusive, depending on scale and features)
For a facility with 20 monitoring points:
- Desigo Compact: $300K–$500K+ upfront, $50K+/year ongoing
- ATEK: $4K–$10K/month all-in, no integrator costs, no surprise fees
Can ATEK handle room pressurization monitoring like Desigo?
Yes. ATEK monitors differential pressure for cleanrooms, classified areas, and fume hoods. Data can be:
- Logged independently in ATEK (native compliance monitoring)
- Received from Desigo via BACnet (leveraging existing Desigo sensors and controllers)
- Combined with other compliance data (temperature, humidity, alerts) in one audit trail
What support can I expect from ATEK?
- 24/7 monitoring — ATEK systems monitor your environment continuously
