INSTALLATION NEWS SPONSORED BY Cung edge venlaon technology provides quality airfiow
Gilberts, one of Britain’s leading independent air movement specialists, has employed cutting edge ventilation technology for main contractor Kier Construction for the new Don Valley Academy & Performing Arts College in Scawthorpe, Doncaster. The school is part of the Delta Trust, which aims to establish a Northern Alliance to transform educational outcomes in the region, with a core value of promoting environmental awareness and protection locally, regionally and globally. To meet the requirements of the Facilities Output Specification (FOS), and Department for Education school building guidelines (BB101 and BB93), Gilberts has supplied its state-of-the-art Mistral Fusion System (MFS) stand-alone, ductless, dynamic hybrid ventilation solution for multi- occupancy rooms.
The modular design of MFS has meant one core product has been used to address design configurations of ventilation through the wall or through the roof in all teaching spaces. Thus, 130
MFS 128 units paired with Gilberts’ WMZ glazed in façade louvres have been utilised to deliver appropriate airflow and quality into the classrooms with minimal heat loss throughout the three-storey building. A further four MFS units were then configured to create two natural ventilation roof terminals (MFS-VN), delivering fresh air intake and stale air extract for the main hall, in conjunction with four WHC high performance façade louvres.
Separately Gilberts’ Mistrale 75 natural ventilation façade louvre cassettes with VN75 dampers have been used to allow fresh air into non-teaching areas.
Kier contracts manager for the project Mike Gorman, explains: “Gilberts’ breadth of product and expertise meant we could, from one source, obtain the key elements we needed to ensure compliance with the ventilation criteria, knowing that the few component types required would all integrate as required, regardless of different
subcontractors installing the façade and building services. The stand-alone, duct-free format of the MFS meant the whole installation was less complex than alternative solutions.”

Sennel Commercial’s KalGUARD delivers superior protecon compared with other water condioners and soeners
Meeting the needs of resident students and staff for a seamless supply of hot water is of paramount importance to prestigious independent boarding school, Canford School, yet the area’s hard mains water (at 260ppm) can compromise this requirement. To promote plant protection and efficiency, the school’s maintenance team has historically installed different types of water conditioners and softeners
across its 14 plant rooms, with varying, but generally unsatisfactory, results. For example, softeners, did not meet the school’s targets of waste water and maintenance reduction, while other products failed to adequately control limescale.
In a recent trial, the school organised a site test to compare KalGUARD, a uniquely-driven electrolytic device from Sentinel Commercial, against a well- known alternative technology device. The products were installed in two separate plant rooms, each with a brand new Hamworthy DR-FC EVO condensing water heater, both servicing different halls of residence of almost exact occupancy levels.
The systems were set to run in early 2017 and were subsequently inspected in February 2018 (the leading alternative device) and March 2018 (KalGUARD).
“After a year in service, it was evident that the water heater protected by KalGUARD was much cleaner than that paired with the alternative
device. In addition, KalGUARD is more compact, whereas size is a negative with the other device. On that basis, we decided to use KalGUARD for all of our plant rooms going forward. KalGUARD units are price compatible and the results are very encouraging. Also, the personal service we receive from Sentinel is first class,” explains Martin Pope of Canford School.
KalGUARD’s technology is based upon a methodology that is recommended by ICOM and the UK Building Services Compliance Guide to Part L. KalGUARD is non-LSI dependent, sized according to demand, and just one unit is needed to treat an entire system when installed on the rising main before the tank and booster sets. KalGUARD doesn’t waste water or require consumables and is extremely low maintenance.

Luceco and Ensigna Construcon shine at Harris Academy Merton
LED lighng technology has enabled Harris Academy Merton to beer ulise indoor spaces
Harris Academy Merton is a member of the Harris Federation, a group of 44 primary and secondary academies in and around London educating some 30,000- young people. The federation is a not-for-profit charity created by Lord Harris of Peckham who takes active interest in the success of the academies. LED lighting technology enabled the academy to be optimised to accommodate assembly areas and the range of different indoor sports activities, as well as a multitude of additional functions within the school calendar. A notable cost effective and energy saving lighting solution provided by Luceco and Ensigna Construction at Harris Academy Merton was the installation of LED LuxPanels in a double height multifunctional hall with high ceilings. Glare control and adequate luminance on the vertical combined with good uniformity are necessities in this application. A 4,200-lumen variant of LuxPanel was used to provide lighting levels suitable for many functions including assembly, examination facilities and sports activities.
High efficiency LuxPanels from Luceco are quick and easy to install into exposed grid ceilings, with remote 'plug and play' drivers. Available in standard fixed output, dimmable and emergency options with no maintenance or re-lamping requirements over their lifetime, LuxPanel eliminates the need for high access equipment normally required for lamp maintenance, as well as benefitting the environment in terms of energy efficiency and lamp disposal. Choosing the right lighting in these spaces can be particularly challenging as a main hall is required to serve a variety of different uses. High efficiency backlit panels provide a solution, have a completely frameless appearance in the ceiling plane and boasting a market leading efficacy of 152Llm/cW.

Polypipe Terrain, the UK’s leading manufacturer of waste and water management systems, is to help to complete the UK’s tallest residenal complex
Polypipe will supply ventilation, drainage, soil and waste systems to the colossal £385 million Deansgate Square development in Manchester city centre. The 2.7-acre site will comprise 1,508 luxury apartments and across four high-rise blocks, including the 200m, 65-storey South Tower – the UK’s tallest residential building, surpassing the 50-storey St George Wharf Tower in Vauxhall, London, which stands at 181m.
Main contractor Renaker selected Terrain to design the vent piping. Polypipe devised a system that incorporated its exclusive P.A.P.A. (positive air pressure attenuator) and Pleura Vent system, which work in harmony to regulate air pressures within pipework and eliminate the need for a secondary vent.
Jonathan Greenwood, technical sales manager at Polypipe Terrrain, says: “The height of the development posed a unique challenge for the designers. The drainage stacks throughout the building had to manage huge amounts of pressure so

a robust solution was required. Polypipe Terrain was able to supply a system that limited the pressures placed on the base of the stacks.
“By installing P.A.P.A. valves we were also able provide the developer with significantly more space in each individual apartment within the tower.” Terrain also provided FUZE HDPE drainage stacks to minimise cost, installation times and resources, and a tailored PVC piping system. The stacks also have fewer joints to reduce the risk of leaks. Andy Moss, director at MWA Ecosystems, which installed the system, said: “Polypipe Terrain was not only able to provide superior products and services, it also offered greater design freedom. We were able to reduce the amount of space, time and labour needed to deliver a drainage system suitable for such a prestigious development.”
