Le Chéile Secondary School

Kieran Callaghan Electrical Ltd played an integral role in the hugely impressive Le Chéile Secondary School – the first Catholic secondary school to be opened in Ireland in 30 years.

The extensive new educational facility at Tyrellstown, Co Dublin, which caters for 1,000 pupils, is the embodiment of modern schools, utilising advanced teaching technologies and built to the latest energy saving standards.

Kieran Callaghan Electrical Ltd was responsible for the complete electrical installation contract that including the state-of-the-art new school building as well as the sporting facilities and public lighting for the new car park and access roads. The school incorporates over 30 classrooms plus specialist rooms such as dedicated science laboratories; metal work, wood work, computer, engineering and technical rooms; and a canteen with a full-size industrial kitchen and staffing office facilities. Also included is a multi-use, sub-divisible sports hall/theatre with associated changing areas and toilet facilities.

The wider site includes purpose-built access roads and car-parking facilities with associated public lighting in addition to the new flood-lit sports playing fields.

The scope of works included full electrical installation of the main switchboard and sub- distribution boards, conduit, trunking and wiring, internal and external lighting services (low energy lighting), and emergency lighting services. Kieran Callaghan Electrical Ltd was also responsible for the fire and security systems ( re alarm, intruder alarm, CCTV and access control) as well as the audio-visual solutions; surge protection equipment, rainwater harvesting control panel and lightning protection. The team worked closely with the main contractor throughout and, specifically, co-ordinated closely on the KNX system, the BMS and the construction of the special needs unit.

For the special needs unit, Kieran Callaghan Electrical Ltd worked closely with the company constructed the precast concrete panels which had the conduit, socket boxes and switch boxes already embedded in them. The panels were assembled on site and, thanks to the team’s involvement in their design, were completed without any issues or adjustments. A high level of co-ordination was also required for the BMS and KNX systems – the latter of which was particularly complex.

Kieran Callaghan Electrical believes the company is the first Irish electrical contractor to install the KNX intelligent lighting system, sockets and power outlets without the need to engage a specialised contractor.

While the main contractor installed the BMS. Kieran Callaghan Electrical provide the necessary wiring for the likes of the heating valves, thermostats, circulating pumps, boilers, and both remote heating control panels.

All testing and commissioning of the entire installation was also carried out by Kieran Callaghan Electrical with the talented team helping to meet a strict handover plan to have the facility completed on schedule.

The intricate nature of this project showcases the ability of Kieran Callaghan Electrical to meet the needs of the education sector, with this project being shortlisted at Ireland’s Electrical Awards 2018 in the Commercial Project of the Year category. Established in June 1996, the company was worked on a wide range of projects in the commercial, education, residential, healthcare, industrial and lighting sectors – all with the same attention to detail and high quality.

Energy efficiency is an integral element of the impressive new Le Chéile Secondary School in Tyrellstown and Hager was central to the overall solution.

The new school was completed using Hager’s Quadro floor standing panel boards, sub- distribution boards, protection devices, Klik lighting distribution equipment and Sollysta wiring accessories.

Scott Wright, General Manager, Hager Ireland, explained, “We were originally approached by the consultant for this project, Matt O’Mahoney & Associates, to advise them on how the lighting control could be shared between the school and the adjoining community centre.

“Our proposal was based on a KNX solution and, subsequently, that was taken on, with the whole job designed as a KNX project. The contractor, Kieran Callaghan Electrical, is a KNX partner and we assisted them in the KNX design of the school. “It all ran really smoothly and we are pleased to be associated with this state-of- the-art school which makes the most of our products.”

The tebis KNX system played a central role in the energy efficiency of the new Le Chéile Secondary School. In this environment, lights can be left on, radiators turned too high or windows left open overnight. With intelligent KNX building automation, the building takes the initiative when employees forget. This not only increases the level of comfort and safety but saves up to 50% in total energy costs. At Le Chéile Secondary School, tebis KNX from Hager connects up a range of electrical functions such as the internal and external lighting systems, heating and ventilation and re and security with the school’s main Building Management System.

This is particularly important for ensuring effective yet energy efficient lighting, with the lighting management system from tebis KNX creating a consistent mix of natural daylight and artificial light to provide a permanent, constant level of light and a fatigue-free working atmosphere. In comparison with normal lighting, this saves up to 50% in energy costs – and valuable work time, as employees no longer have to regulate the light themselves. Hager products installed at Le Chéile Secondary School include the Quadro IP55 boards and enclosures and wiring products from the Sollysta range.

The Quadro boards and enclosures in IP55 are ideal for commercial applications. The Quadro enclosures are designed for enclosed distribution up to 630A and have been designed for ease of installation. Delivered with a pre-mounted plinth and without sides, they can be joined horizontally and vertically to create multiple assemblies.

The Sollysta range of wiring accessories were also used in his project. The range includes, White Moulded, Decorative (available in four finishes; brushed steel, polished brass, polished steel and black nickel), Metalclad and IP66. All terminals on the back face in the same direction, removing the need to rotate the product during installation while a unique patented neutral loop terminal provides easy neutral conductor termination at a workable height for installers.

Troy Panels provided all panels in the project, From Main Distribution board right through to the KNX lighting control boards at the impressive new Le Chéile Secondary School.

This was the first time the company had worked on a KNX project of this kind and it marks one of the larger commercial projects that Troy Panels has been involved in. Martin McKenna, Design and Estimation at Troy Panels, said, “This was a sizeable project and while we have experience of KNX, this was the biggest project that we’ve used it on.

We have a strong working relationship with the electrical contractor, Kieran Callaghan Electrical Ltd, and that proved important in the planning stages which, in turn, meant that the project ran smoothly on site.”

This is reflective of Troy Panels’ philosophy of working with companies to improve process ow, save time and costs. Troy Panels supplies a range of control panels to various sectors in Ireland and the UK. Manufactured and tested to the highest specification, products include Form 2 and 4 distribution panels, MCC boards, PLC controls, bespoke combination unit systems, panels for biomass burners and custom-built panels for the food and beverage sector.

The firm also supplies bespoke poultry controllers, electrical panels for custom-built grain drying facilities, panels for a range of ventilation systems, panels to control feeding systems and heating control systems.

All panels are designed, built and programmed within the firm’s workshop. The company also acts as a manufacturer for other control system requirements, a process which is carried out in-house.

The team at Troy has found over the past few years that, with profit margins getting smaller, they’ve been approached by companies from almost every sector to help them improve a process or control system. The firm has been fulfilling this request through the use of PLCs (Programmable Logic Controllers).
