New Civic Center in London takes control with Danfoss NovoCon
Approximately 500 Danfoss NovoCon digital actuators and AB-QM PICVs are installed in the civic center. Providing this advanced level of control cuts energy consumption and carbon emissions, reduces running costs and creates a comfortable and more productive working environment. Read how Danfoss makes it possible to balance hundreds of valves with one single mouse click.
Danfoss NovoCon, the first multi-tasking digital
actuator to connect a hydronic HVAC system with the Building Management System
(BMS), is part of the energy-efficient design of a new civic centre
for the London Borough of Lambeth. Combined with Danfoss AB-QM Pressure
Independent Control Valves (PICV) and utilising remote fieldbus communication, NovoCon
maintains correct hydronic balance within the building’s Active Chilled Beam
system at all loads. Providing this advanced level of control cuts energy
consumption and carbon emissions, reduces running costs and creates a
comfortable and more productive working environment.

are connected to the BMS via a BACnet communications protocol. This brings many
benefits, including remote commissioning of
the system via the BMS, making it possible to balance hundreds of valves with a
single mouse click. As a result, valuable time is saved on site and much
greater accuracy is achieved compared with using manual techniques.
Being a digital device, NovoCon also has
the ability to collect and store performance data on individual terminal valves.
This is a major advantage during installation and ongoing maintenance. Faults,
such as a jammed valve due to particle build-up, can be identified remotely and
resolved more quickly, reducing disruption for occupants.
The BMS system for the project was designed and installed by
Electracom Projects, specialists in building control systems. The company’s
Director, Bob Gilbert, says having proved highly successful on another large commercial
project in the capital, Danfoss NovoCon was the obvious choice for the new
civic centre. “From our experience, NovoCon does everything it says in the brochure,”
he says. “It is a robust, cost-effective solution that provides a completely automated process
for controlling, monitoring, optimising, and maintaining heating or cooling in a
building. And with NovoCon all this can
be done remotely via the bus communication, which saves significant time and
cost during installation, commissioning and ongoing maintenance.”
fieldbus cables with pre-fabricated plugs for daisy-chain connection, and with
all setting and control via fieldbus, it requires only minimal data points and
fewer wires and cables than standard on/off actuators. “This all means faster, simpler installation
and offers excellent future flexibility,” adds Bob Gilbert.
up, Greg Tracy, a Danfoss Business Development Manager specialising in HVAC/BMS
Projects, says hydronic balance is the only way to ensure a HVAC installation delivers
the intended indoor comfort at optimum efficiency and operating cost. He
comments: “NovoCon takes balancing and control of commercial
heating and cooling installations to new levels of ease, efficiency and
accuracy. Our expert team can work with clients to ensure each system meets the
required design criteria. In addition, Danfoss has developed a NovoCon
BMS CPD Presentation, featuring a live product demonstration, which has
assisted the specification and installation of the NovoCon digital actuator in
a number of prestigious UK projects.”
