The world’s biggest Primark store is making the most of its space through to its venlaon

Gilberts Blackpool, the air movement specialist that provided the air distribution outlets for Primark’s first UK store over 20 years ago, has now facilitated a fresh environment for shoppers at the latest Primark to open its doors, the Birmingham megastore, claimed to be the biggest in the world. Gilberts worked with facilities management company Mitie to ensure air supply throughout the public and staff areas of five-storey, 161,000ft2 (14,957m2) new store, on the former Pavilions site in the heart of the UK’s second city.

“The scale of the project

made it complex,” explains Gilberts’ sales manager, Martin Malyon,” We have an established relationship with Mitie and Primark, but this was certainly the biggest we’ve done together.” Gilberts designed and developed a strategy to ensure appropriate air supply throughout the five floors, from basement upwards, addressing air circulation through the sales areas, toilets, staff rooms, training rooms, fitting rooms, cleaners’ stores and even the detention room, taking into account the impact of a two- storey atrium and mezzanines around it, and air flow to the

support plant.

Gilberts had to address the variety of open ceilings to create the perception of space on the main sales floors, and suspended ceilings in fitting rooms, staff rooms and WCs, taking into account people movement through the various areas. A combination of GSFA swirl diffusers, DG4 ceiling diffusers, GX extract valves, GSL linear slot diffusers and transfer grilles provide air supply internally, complimented by smoke louvres within the atrium, and WGF38 external louvres on the façade from first floor upwards servicing the plant rooms. More than 300 diffusers,

linear diffusers up to 2.4m long, and some 20 façade louvres up to 2.5m x 1.5m were manufactured at Gilberts’ Lancashire factory for on-site installation by Mitie.

“Usually with open ceilings we would fit coanda plates to ensure the occupants below did not feel a draught,” elaborated Malyon. “The feeling was that in a shop, people tend to browse rather than be static, so, with the high ceiling clearance, fitting of standard swirl diffusers was deemed acceptable to create a comfortable environment. Carrier delivers efficient heat pump solution for new welcome centre at RHS Garden Wisley

A new mulmillion pound Welcome Centre at the Royal Horcultural Society’s (RHS) flagship garden at Wisley, Surrey, will be heated by high eciency Carrier AquaSnap airto water heat pumps

Carrier, a world leader in high- technology heating, air-conditioning and refrigeration solutions, is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.

The development is part of a major investment by the RHS in the world- renowned garden, adding new visitor facilities designed to celebrate the best in horticulture. The spacious Welcome Centre is designed as a new arrivals space for an anticipated 1.4 million visitors per year, and includes a 100-seater restaurant, shop, and one of the largest plant centres in the UK.

The centre’s heating system includes two Carrier AquaSnap

30RQP air-source heat pumps, with a combined capacity of 600kW. The scroll compressor-based units are highly energy efficient, harvesting ‘free’ energy from outside air and upgrading it for use within the building. The low noise units have a significantly reduced refrigerant charge due to use of Carrier’s innovative compact Brazed Plate Heat Exchangers, further reducing environmental impact.

James Meadows, Carrier applied products sales engineer, says: “AquaSnap’s compact all-in-one packaged design is optimised for part-load applications where high Seasonal Coefficients of

Performance (SCOP) are required. It includes an inbuilt hydronic module that speeds up installation and

commissioning on site and reduces overall project costs.”

The Carrier heat pumps, specified by NG Bailey as part of the design and build project, are located remotely from the building and connected to the centre’s heating system via 80m of insulated underground pipework.

Robert Steed, senior mechanical project engineer with NG Bailey, who headed up the project, says: “We specified the AquaSnap heat pumps at the design stage because we were keen to ensure the best possible energy efficiency, performance and reliability, while minimising impact on the environment. The Carrier units support the building’s strong environmental credentials and accrue points under BREEAM.”

He adds: “The project was highly successful and we worked closely with Carrier throughout the design and installation. The support they provided, in terms of both attendance at planning meetings and technical information, was excellent.” Kershaw Mechanical Services Complete Work on London’s Biggest Cinema

Kershaw Mechanical Services is delighted to have completed works at the newly expanded, stateof theart Cineworld at the O2 entertainment venue

The expansion makes it London’s largest cinema, with over 4500 seats and the introduction of an additional eight screens offering VIP and 4DX experiences. The new additions make it one of the UK’s most technologically advanced cinemas.

Kershaw Mechanical Services provided a full mechanical service installation including a building management system, air conditioning and heating and ventilation for the 19 screen cinema.

The work was undertaken by the Special Projects Division in Kershaw Mechanical Services and follows a long line of previous Cineworld projects. Colin Newstead, Kershaw Mechanical Services, Special Projects Division, says: “We are delighted to have completed works on this ultra-modern cinema

located within the iconic O2 building. We have a long-standing relationship with Cineworld and we are proud to have successfully completed yet another project with them” Following on from competition, the Special Projects team are now excited to be shortly starting work on one of Cineworld's latest additions – a £48million cinema complex in Plymouth. The new development includes a 12- cinema picture house containing the South West’s first IMAX screen.

Paent comfort a priority at Walsall Manor Hospital’s new unit

A new Intensive Care Unit (ICU) has opened at Walsall Manor Hospital, which provides specialist care to crically ill paents. Kingspan Kooltherm Pipe Insulaon has been installed to assist with eecve temperature management

Walsall Manor Hospital, based in the West Midlands, is managed by Walsall Healthcare NHS Trust and provides acute care and multidisciplinary services to around 260,000 people in and around Walsall. The new ICU has merged the hospital’s Intensive Therapy Unit (ITU) and the High Dependency Unit (HDU),

to create an 18-bedded unit. Due to the nature of critical care, it was essential to maintain a safe and comfortable temperature for patients. M&E contractor, Chase Insulations, installed 3000lm of Kingspan Kooltherm Pipe Insulation on the HVAC pipework in conformance with Kingspan’s high standards. The insulation delivered a simple, low maintenance solution for effectively reducing heat transference and ensuring optimal heating and cooling system efficiency.

Samuel Hitch, managing director of Chase Insulations, discusses the specification at the hospital: “It was important for this project that there was minimal disruption to the rest of the site, and that we got the unit

operational as soon as possible. Having worked with Kingspan Industrial Insulation before, we knew that their insulation is easy to handle and lightweight, which enables a quicker installation. Using premium performance phenolic lagging also meant we could help keep the project costs comparatively lower than using other insulation materials.” Midwest Electrical Services carried out all the mechanical installations, including the centralised steam heating system, domestic hot water, cooling and filtered ventilation systems running throughout the ICU’s roof space, walkways and plant room. The heating and cooling systems are also distributed to the Trox Active Chilled Beams. These serve the

heating and cooling needs within each bed bay and communal areas within the ward space. As a result, it was especially important that the insulation used across the pipework was suitable for an environment where a patient’s immune system could be easily compromised. Kingspan Kooltherm Pipe Insulation has been awarded a best-in-class Eurofins Indoor Air Comfort Gold certificate, recognising it as an outstanding material according to the VOC Indoor Air Quality emissions standards. The certification also displays compliance with the relevant requirements within standards such as BREEAM, LEEDv4 and EMICODE. BUILDING SERVICES & ENVIRONMENTAL ENGINEER JULY 2019 35
