Subnet: BMS engineering, commissioning and HVAC control for critical buildings

Subnet designs and commissions Siemens Desigo and Distech Controls systems for pharmaceutical, data-centre and commercial buildings.

Summary

Best for
Irish building projects requiring controls engineering, commissioning and documented handover.
Less suited to
Purchasing a Subnet-manufactured controller or a generic self-service cloud platform.
Deployment
Engineered on-site BMS with integration, commissioning and ongoing support.
Data in
Building controls, HVAC equipment and energy measurements through specified project interfaces.
Pricing
Project and service pricing requires a quotation.

Overview

Subnet is an Irish building-controls engineering business with a particular focus on pharmaceutical and data-centre environments. Its company description covers design, build, integration and commissioning of BMS and HVAC systems. The work includes the engineering detail and documentation needed for complex projects, rather than only installing sensors or providing remote charts. Its public material distinguishes qualified and non-qualified building-management contexts. For an owner comparing suppliers, Subnet’s role is that of a specialist implementation and support provider around established control platforms, with project delivery and operating requirements shaping the chosen system.

Offering

The Siemens offering covers the Desigo building-automation portfolio and its management platform. Subnet describes engineering and integration that brings equipment information, events and operation into a common environment. Desigo CC provides the supervisory context while the wider controls portfolio serves plant and room-level functions. This is an integration practice rather than a claim that Subnet manufactures the Siemens hardware. The choice of controller, field interface and application software remains specific to the project. The same engineering responsibility extends to configuring useful operator views and ensuring the delivered system can be maintained after handover.

Technology

The Distech ECLYPSE offering adds another control-platform route. Subnet describes engineering and commissioning for ECLYPSE APEX, including its fieldbus interfaces and connections between operational and IT systems. The material names RESTful integration and an Azure IoT Hub connector alongside the controller environment. These are model-specific capabilities within the Distech portfolio, not proof that any arbitrary cloud application has already been integrated. Subnet’s role is to apply and commission that hardware in the building. The result combines controller programming, point mapping, communications and operator functions rather than treating protocol support as the whole project.

Markets

The quality-management description identifies an NSAI-certified system covering design, build and execution of building-management projects under ISO9001:2015. It links that system to project reviews, test procedures, validation, corrective action and documentation. Those practices are particularly relevant in pharmaceutical and other critical environments where an undocumented operating change can create more than an energy issue. The Exergio partnership adds a separate route for building-performance analysis and optimisation. The partnership complements the controls work; it should not be confused with an in-house Subnet analytics product or an automatic saving guarantee for every building.

Company

The company trades as Subnet Automation Support Limited and gives its office at the Port Tunnel Business and Technology Park in Dublin in its contact information. Its current website highlights Siemens and Distech Controls relationships and ongoing work on data centres, pharmaceutical facilities and commercial buildings. Energy-related projects sit alongside commissioning and control-system support rather than replacing those services. The company’s focus on building automation also distinguishes it from unrelated businesses using the Subnet name in electrical substation software or networking. The precise Irish identity and control-platform expertise are central to understanding the services described here. Its official company profile dates the business to 2017 and identifies Dublin, Ireland as headquarters.
