BNP Paribas Real Estate – HVAC Upgrade

Energy & Technical Services was appointed by BNP PRE to improve the comfort conditions and reduce the capital expenditure at 100 Hagley Road, Birmginham. Large parts of the building were not being heated/cooled correctly resulting in the central boilers and chillers being left in operation 24/7. Despite multiple engineer call outs, BNP continued to receive complaints from tenants and were quoted £500,000 to repair the existing HVAC system.

We quickly identified the flow of heat exchange fluids could be improved from within the installed pipework. The hot and cold water circuits were flushed out over a period of eight weeks with the tenants still in occupation and new flexible hoses were fitted to all fan coil units. Energy & Technical Services successfully recommissioned the existing HVAC system for £70,000 instead of £500,000, as originally quoted.


BNP required the building to remain fully operational whilst the works where carried out. Early stakeholder engagement with client representatives and tenants helped identified troublesome areas in the building and ensured works did not disrupt the existing tenants.

Added Value / Achievements

As impartial consultants, we were able select the most appropriate course of action for our client avoiding unnecessary/costly repairs. After works were completed, comfort conditions were met resulting in a massive reduction in tenant complaints. In addition to the money saved from endless call outs, energy consumption was also reduced.

Wokingham Borough Council – 49% Proven energy savings

The existing BeMS controls for the site were poorly controlling the LTHW boilers across various plant rooms at the site, some plant areas were found to be running 24hrs a day. The existing building controls were removed and replaced with RDM controls utilising improved optimum start/stop algorithms, alongside demand-based temperature control and vastly improved zone control.
