SAV’s Low Carbon Technology Centre – open to all
With a highly successful Open Day on the 4th November 2011, SAV has officially launched its Low Carbon Technology Centre. During the day around 80 delegates from the building services industry had the opportunity to learn more about energy-saving initiatives from overseas, participate in interactive workshops and attend CPD-accredited seminars.
“We were delighted with the success of the day and the very positive feedback we have received since,” commented SAV Managing Director Lars Fabricius. “The mix of information and activities, along with the networking opportunities, ensured that everyone had a productive and thoroughly enjoyable time. I would also like to thank all those who took part, as their interest and enthusiasm were essential ingredients in what was a very satisfactory day for all.”
Learning from experience
Since the 1970s oil crisis, Denmark has invested heavily in energy efficiency and has an enviable track record in reducing energy consumption and exploiting the potential of renewable energy sources. Delegates to the SAV Open Day were able to hear at first-hand how they went about it, and how the lessons learned can be applied in the UK.
Speakers included Ebsen Mortensen of the Danish Energy Industries Federation and Bjarne Bogner of EC Power, who outlined key elements of the Danish strategy and, in particular, the vital role that CHP and district heating have played in the country’s achievements. Delegates were also able to hear more about some of the latest initiatives from Danfoss – for which SAV is the sole UK distributor of district heating products.
Getting to grips with Code W
Following the changes that were made to both the CIBSE Commissioning Code W (Water Distribution Systems) and the BSRIA Commissioning Guide in 2010, there has been some confusion over acceptable commissioning practices. To clarify the situation, Chris Parsloe of Parsloe Consulting (and formerly of BSRIA) gave a detailed presentation on the new requirements.
His address included how to make best use of Differential Pressure Control Valves and Pressure Independent Control Valves, neither of which had been included in the previous Code. He also provided advice on taking meaningful measurement in systems with ultra-low flows.
Hands on with SAV
The SAV Low Carbon Technology Centre incorporates all of the company’s products in its HVAC systems and a series of hands-on workshops enabled delegates to fully understand how the systems interact. Live demonstrations of CHP, heat exchangers and commissioning systems gave a real ‘feel’ for the inherent flexibility of the systems and the benefits they offer for a wide range of systems.
Of particular interest was the ‘miniature district heating system’ running through the Centre, with heat generated from the LoadTracker CHP distributed to deliver both heating and domestic hot water. Visitors were also able to see SAV’s commissioning module test rig, simulating a cluster of four fan coil units with the ability to demonstrate different methods of pressure control.
Earning CPD points
The Open Day concluded with a series of well-attended CPD-accredited seminars covering the key topics that had been addressed in other ways during the day. These included applications and implementation of CHP, the use of heat exchangers to generate instantaneous DHW in district heating systems and innovative commissioning solutions for ultra-low flows and other systems.
