Commissioning Specialists Association (CSA) chairman Mark Todd offers a thoughtful piece on why we as a sector need to engage more with our local communities - and why CSR is about more than simply looking good.

Building regulations specify that sheet metal ductwork leakage testing “should be carried out in accordance with the procedures set out in B&ES DW/144” for new buildings (ADL2A) and for existing buildings (ADL2B).

It is now more readily understood that correct sizing and careful pump selection can make a significant difference to the overall energy and CO2 output, as well as the need to futureproof these designs.

Hydronic system balancing is one of the more complicated tasks faced by building services engineers and historically heating and chilled water systems were balanced by specialist engineers only.

Speed is of the essence when it comes to pipe fitting in today’s large-scale projects. Scott James offers his advice on making the right choice.

M&E contractors and building services managers looking to maximise space within plant rooms have a checklist of utilities to consider - heating systems are just one of many to juggle. And boilers are just one piece of the plant room jigsaw that needs to slot into place. However, with strict guidance and legislation around the area required for ventilation, access for handling units and clearance in line with manufacturer’s guidelines for maintenance for example, it is a headache for many.

Mark Todd of the Commissioning Specialists Association calls for new ways of working to match the new technologies now available to the construction industry – and to help achieve better buildings for the future

James Townley explains why commissioning is so important for closed heating or cooling systems, and offers advice on the approaches that can help ensure effective long-term operation right from the start.

Dave Lancaster discusses why commissioning of pipework is so important, and shares his insights on the best approaches to this vital process.

Installing and commissioning a water heater is a very different process to the one you would carry out for a boiler. Dan Martindale has put together a guide to the key stages of commissioning a water heater.

The key to the successful commissioning of a project is a commissioning plan. Tony Anderson, a member of the Commissioning Specialists’ Association’s training committee and assessment panel shares his experience of how this simple tool provides clarity to commissioning projects.

Dave Ward of Hamworthy Heating, explains what a commissioning job entails and why it’s worth considering — not just in terms of efficiency, but also customer safety.

Marflow Hydronics has further developed its web site to enable customers to download relevant technical information, including BIM models, via a new product-downloads section. In addition, all product pages can be captured in PDF format and used as a data sheet.

Danfoss ASV automatic balancing valves have been installed in five social-housing tower blocks in south-east London to overcome problems of unevenly distributed heating from central boiler plant. They were installed with minimum inconvenience to tenants.

Everyone appreciates the important role of commissioning the services in a building, but the work of the Commissioning Specialists’ Association (CSA) is less well understood. Andrew Watkin, CSA chairman, explains the role of the association.

The annual awards of the Commissioning Specialists’ Association is open for entries. This is the third year of the awards, which acknowledge the achievements and efforts of companies and engineers. Products, systems and services that are essential for the smooth and efficient operation of any built environment will also be recognised.

Getting the right balance on domestic heating system is a simple task with the help of the Grundfos Alpha3 system. The company says that 86% of domestic heating systems are not balanced and that balancing a system can reduce heating costs by 5 to 17%.

Marflow Hydronics has further developed its web site to enable customers to download relevant technical information, including BIM models, via a new product-downloads section. In addition, all product pages can be captured in PDF format and used as a data sheet.

Self-regulating valves have the potential to achieve cost-effective and optimised control in distribution networks. Paul Wightman of Albion Valves considers how to get the best from them.

Making alterations to a building and its services without making corresponding changes to the controls will quickly lead to poor performance and increased energy consumption. controls are not fit-and-forget technology — as Matt Peasnall of Trend Control Systems, explains.

Andrew Watkin, chairman of the Commissioning Specialists’ Association looks forward to the second year of the association’s awards.

Commissioning is the key to ensuring that every heat interface unit (HIU) in a district-heating system delivers. Neil Parry of Altecnic discusses the issues involved.

As part of major renovation of the heating-distribution and complex ventilation system of the Happyland leisure centre in Klosterneuburg, Austria, 45 Belimo EPIVs (electronic pressure-independent control valves, the orange units in the picture) were installed on eight distribution circuits during operation to avoid loss of revenue.

Giacomini has introduced a balancing-valve set to complement its HIUs (heat interface units) for multi-dwelling properties. These valve sets are designed to optimise the efficiency of communal heating systems by carefully balancing the heating network throughout.

Efficient management of building energy performance requires access to current, meaningful data about the performance of building-services systems. Elio Galluzzi of SAV Systems explains why the solution begins with commissioning.

Belimo’s replacement actuators for globe valves have customisable parameters and are equipped with a universal valve neck and stem adapter. They can be installed quickly and easily on virtually all valves from manufacturers worldwide.

Marflow Hydronics has further developed its web site to enable customers to download relevant technical information, including BIM models, via a new product-downloads section. In addition, all product pages can be captured in PDF format and used as a data sheet.

Eclipse Magnetics offers a universal flush adaptor attachment to enable installers to carry out routine system flushes quickly and easily by attaching flushing equipment to its BoilerMag boiler filter, using the filter as the access point. This adaptor can be attached to the back of the BoilerMag port block in just a few seconds and is compatible with screw-fit or female cam-lock hoses — so that a wide range of flushing equipment can be used.

IMI Hydronics has created a solution to the problems caused by inaccurate control technology in heating or cooling systems. TA-Modulator is a highly precise pressure-independent balancing and control valve. It is used with a range of digitally configurable actuators, TA-Slider, to deliver the exact amount of energy to ensure perfect comfort and reduced energy costs.

The PT40 range of radiator control valves from SAV Systems helps to reduce energy waste in heat networks by ensuring that radiator systems are well balanced. These TRV sets are presettable to a flow-rate limit at each radiator, in line with the CIBSE ‘Heat networks code of practice’, eliminating the need for traditional balancing.
