With views across the River Mersey and the city’s UNESCO world heritage site, Exhibition Centre Liverpool is the newest addition to the existing Arena and Convention Centre (ACC) Liverpool, already home to the BT Convention Centre and Echo Arena.
With an ElitePLUS 4 acoustic roof system, the recently-built venue has already been earmarked for a range of exhibitions, from medical wound care to cruise holidays and wedding shows. Acoustic and thermal performance were key aspects of the building’s performance so it is not surprising that the overall roof construction provides 45dB sound reduction and thermal transmittance of just 0.15W/m2K.
The Euroseam® outer profile used on this system is mechanically fixed by folding the seams on each edge of the sheet over a stainless steel halter. This is attached to the building structure via the Quattro spacer, which is fixed through the liner sheet into purlins attached to the main structure of the building. Euroseam® forms the outer layer of the ElitePLUS roof, combining with insulation, the MW5 Liner and Quattro as the main constituent parts.
The MW5 liner profile was supplied in black; not a typical liner colour. Bright white or High Reflective colours are usually employed on the inside of metal roof and wall systems to maximise natural daylight and reduce energy consumption from artificial lighting. But in this case a black finish is understandable, providing an influential element in the control of ambient and spot lighting at such a venue; all but eliminating unwanted reflections during performance and theatre events. It also matches the design of the colour scheme, which runs from outside the building to the interior, with a striking monochrome palette that contributes to the clean, modern aesthetics.
To top it all off the Euroseam® profile on the outside of the roof was an ideal substrate for an expanse of photovoltaic (PV) systems. The 250KW PV system featured PV panels attached to a pitched framework to provide the optimal angle for solar energy capture. The framework was anchored to the roof using a special Euroclad clamp, which avoids sheet penetrations, whilst providing a secure anchor. This ‘energy from envelope’ ethos combines with excellent thermal insulation to help minimise the environmental impact of the building.
