The famous Royal Liver Building in Liverpool has undergone a major energy efficiency upgrade to preserve its Grade I listing.
The iconic structure on the Liverpool Waterfront was facing the need for additional refrigeration condenser units on the rooftop to deliver cooling to the building, which would have jeopardised its graded status.
The building, which was built between 1908 and 1911, is due to go through a major renovation, with a new office space, gym, restaurant and a visitor attraction planned.
To avoid any changes to the rooftop, Yorkshire-based energy efficiency specialist BG Energy Solutions (BGES) was appointed to install a range of energy efficient upgrades.
A new plant room was created in the building’s basement to house heating and cooling equipment that feeds a 7,500 litre storage tank. Existing low temperature hot water (LTHW) pipework was extended into the new plant room and, via a heating-plate heat exchanger, maintains a minimum temperature of 20°C when the building is occupied.
Meanwhile, a new 600kW dry cooler maintains a temperature of less than 28°C in the buffer vessel during summer months via a cooling-plate exchanger. The system also maximises free cooling from external ambient air.
A new controller for the system has been fitted, along with a ‘web supervisor’ that provides a complete graphical interface that can be accessed on any PC browser, tablet or mobile device.
