Total control produces energy savings
A new Building Management System (BMS) from Distech Controls is making a major contribution towards improving indoor climate quality at a refurbished office block in Oslo. Provided by system integrator SD-Consult from Norway, the new control system is also helping to dramatically reduce energy consumption and carbon emissions for the building’s tenants.
The building is undergoing a total retrofit with eight new air handling units installed, as well as an upgrade of the Building Management System (BMS) to include an energy management programme. The Hydro-owned office building, featuring a complete meeting centre with 22 meetings rooms, required a control system that could be quickly installed to meet demanding project timescales. The system also needed to be easy to use, incorporating optimiser functions and smartphone capabilities.
“There were tight deadlines we had to meet on this project as everything needed to be done before the customer moved in” comments Erik Nordli of SD-Consult. “Thanks to Distech Controls, the installation process was incredibly simple and swift. It just worked perfectly first time and, with no time to test or check for errors, that was extremely important.”
SD-Consult selected the Distech EC-NetAX web-based, integrated building management platform for the project allowing seamless integration between heating and cooling within the HVAC plant. EC-NetAX offers multi-protocol, multi-function capabilities to provide seamless and intelligent integration of different building services sub-systems using a web browser. On this project, it offers a common platform for key BMS functions, such as, network control, energy monitoring, alarming, data logging management, and audit trails; communicating with building services equipment using the BACnet protocol. In the event of plant failure, the BMS automatically triggers an email to SD-Consult with historical trend logging and reporting also activated via email.
Distech Controls’ EC-BOS network controller was also installed by SD-Consult and connected to 20 ECB-600 BACnet field controllers, which provide the real-time control functions. The EC-BOS combines integrated control, supervision, data logging, alarming, scheduling and network management functions with Internet connectivity and web serving capabilities in a small, compact platform. The ECB-600 controllers’ capacity was expanded by use of 12 ECx-400 expansion modules connected via a sub-network. The installation included six BACnet IP Routers and 66 ECB-VAV controllers, which are perfect for applications from single duct to fan powered VAV with reheat and radiation heating.
The project incorporated 66 of Distech Controls’ new Allure EC-Smart-Vue sensors, which can measure four different parameters in one sensor; temperature, humidity, CO2 and motion. The integrated sensors interface with the BACnet ECB Series controllers via the controller sub network. For complete ease-of-use, the DGLux has been used so operations can be managed on every platform and on apps through the internet.
