Data Centre Savings

Data centres need practical ways to reduce cooling energy, improve efficiency, and cut carbon without major plant replacement or unnecessary project risk. DLH is an OPEX-led retrofit solution that reduces avoidable cooling energy waste through remote optimisation of existing systems.

There is no major hardware programme, no widespread site disruption, and all installation and configuration work can be carried out remotely. That makes DLH well suited to operators looking to lower non-IT energy overhead, support better PUE performance, and deliver measurable savings fast.

Illustrative savings by data centre size

Small edge or colocated site

100-250 kW IT load Annual savings with DLH: £18,000-£55,000 CO2 reduction: 35-90 tonnes

Medium enterprise site 

250 kW-1 MW IT load Annual savings with DLH: £55,000-£220,000 CO2 reduction: 90-350 tonnes

Large colocation or regional site 

1-5 MW IT load Annual savings with DLH: £220,000-£1.1m CO2 reduction: 350-1,750 tonnes

Hyperscale facility

 5-20 MW+ IT load Annual savings with DLH: £1.1m-£4.4m+ CO2 reduction: 1,750-7,000+ tonnes

Illustrative assumption: cooling is a major share of total data-centre energy demand, and DLH delivers a conservative reduction in avoidable cooling-related energy waste depending on load, cooling design, operating conditions, and electricity tariff.

DLH helps data centres reduce cooling energy, operating cost, and carbon through a low-disruption retrofit solution delivered remotely and funded through OPEX rather than CAPEX.
