Al Abdali Medical Centre is a multi-specialty hospital in Amman, Jordan. The building is powered by an 8.2 MW photovoltaic power plant, the largest solar plant in the world powering a single healthcare facility according to its developer. Luceco with partners MEMCO supplied an energy efficient LED lighting solution for this state of the art hospital.
The medical centre has a 200 bed facility and provides best practice patient-centred care as well as promoting research and education. It was considered that the lighting played a pivotal role in relation to wellbeing for both patients and staff and that as costs play a key role in the healthcare environment, estate maintenance and operating expenditure could be substantially reduced by introducing a highly efficient LED lighting design.
Hoval goes the extra few hundred miles
Hoval boilers are well known for their ease of installaon and commissioning but there are mes when the boiler design can do nothing to migate external factors.
Such was the case when Hoval engineer Phil James went to commission two Hoval UltraOil boilers at an energy centre serving a radar station on St Kilda – and what should have been a two-day journey took over a week. St Kilda is a UNESCO World Heritage site in the northernmost part of the Outer Hebrides. It was evacuated in 1930 and is now home to a few contractors maintaining the radar station, as well as occasional visiting naturalists. Travel facilities to and from the islands are limited at the best of times but when the regular boat breaks down things get really challenging.
Rising to the challenge, Phil was able to hitch a lift to the island of Harris, with a passing diving boat, and then onwards to Skye in the same boat – journeys that took a few days in themselves. From Skye it was then a matter of using public transport and hitch-hiking for a further two days to get back to his car.
In all the journey took over a week but the radar station on St Kilda now has an energy-efficient boiler installation that will help to keep the cold out for the few people residing there.

Viega provides me saving pipe connecon system for University of Essex student accommodaon Viega’s Megapress and Profipress piping
systems have been used on the refurbishment of the Bertrand Russell Tower at the University of Essex’s Colchester Campus.
The 16 storey Bertrand Russell Tower is one of six student accommodation towers built in the 1960s on the Colchester Campus. The renovation included the complete replacement of all interior elements and building services to modernise and improve the tower for better building performance and student experience. The timeline of the project required all the work to be completed between autumn 2018 and September 2019, including the removal of the existing fixtures and fittings. This meant that the installation of the building services had to be completed in a compressed timeframe. Thick-walled steel tube was specified for the new heating pipework in the tower to help ensure a longer life for the system. Specialist plumbing and heating contractor, F.G Fennell was selected to carry out the work and its plan

Offering an efficacy up to 129 Llm/cW, Platinum LED Downlights were installed in communal areas, circulation spaces and corridors, offer running cost savings of up to 80% when compared with traditionally lamped fittings. Other luminaires in this downlighter family include the Platinum Surface Mount providing opportunity for creative lighting design where a recessed ceiling void is not available and the popular Platinum Mini. The other principle luminaire installed was the IP65 rated Edgelit Framed LuxPanel installed in the medical procedure rooms. The 600x600 Edgelit panel features a TpB polycarbonate diffuser and is suitable for use in 15 or 24mm standard exposed grid ceilings delivering up to 115Llm/cW. Variations include fixed output and dimmable drivers as well as being Luceco Wireless Lighting Controls compatible.

was to use a press connection system for the domestic hot, cold and potable water pipework. For the thick-walled heating pipework the intention was to use a combination of threaded and welded tube.
Megapress, allows thick-walled steel tube, with diameters between inch and 4 inches, to be cold press connected. When compared with alternatives such as welding, grooving or threading tube, Megapress provides between a 60% and 80% time saving, depending on the tube diameter. The full range of sizes were required for the refurbishment of the Bertrand Russell Tower.
Viega’s patented SC-Contur technology delivers a 100% positive leak if the fitting is inadvertently unpressed and is clearly discernible during leakage testing or when the system is filled for the first time.

Wiltshire County Council Chooses Carrier Chillers in Air Condioning Upgrade
Carrier watercooled screw chillers, with a combined cooling capacity of more than 1.4MW, are providing high eciency, reliable cooling at Wiltshire County Council’s headquarters.
Two Carrier high performance AquaForce® 30XW-V variable speed chillers were selected for installation at the Council’s headquarters in Trowbridge, Wilts. AquaForce chillers are based on proven inverter-driven twin-rotor screw compressors, which allow the cooling capacity to be precisely matched to the changing building load, significantly reducing power input. Automatically adjusting the capacity results in Eurovent-certified industry leading values for European Seasonal Energy Efficiency Rating (ESEER) of up to 8.
Continuity of cooling had to be maintained throughout the project to enable the building to continue operating. To ensure this, K4 Service located a temporary chiller in the Council carpark and connected it to the building’s chilled water system, maintaining supply to the air conditioning during the changeover.

The basement plant room housing the chillers had very restricted access, requiring a carefully planned and executed lift-and-shift operation. The previous units were disconnected and extracted using a crane through a deep well above the plant room, and the new Carrier units were lowered into position. Due to the compact design and configuration of the Carrier chillers, it was possible to deliver the units into the tight plant room without the need to modify the structure, saving time and money on the installation. With a width of approximately 1.25 meters for units up to 1,000kW, the chillers can pass through standard-size door openings and require minimum floor space.
