Real-Time Energy Monitoring at Nile St with McLaren Construction Ltd

In 2014-16 Greengage acted as Energy Savings Opportunity Scheme Lead Assessors for several organisations, providing energy efficiency advice to identify prospects for investment in energy efficiency projects.

One of those organisations was McLaren Construction Ltd who have been leading voices in the industry seeking to minimise the environmental impact of construction activities.

When the business was initially assessed in 2015/16 we focussed on identifying the energy use of the dozens of construction sites, offices and transport activities to articulate the extent of the challenge for the group. Head and regional offices were easy enough to monitor through half-hourly energy meters installed by energy companies as part of their responsibilities set out by Ofgem. Construction sites, however, with limited infrastructure, located around the country and often using energy through a temporary builders’ supply posed a different challenge.

Considering that the initial energy footprinting works identified that construction site activities cost the business almost £200,000 annually, Greengage identified that opportunities existed at site to save energy and costs.

Greengage carried out a review of technologies that could be used to gather better data and recommended that Energy Deck be tasked with becoming the energy metering & software provider for a demonstration project.

In winter 2016/2017 the Nile Street project was nominated as the testbed for the technology trial and the project team were briefed about the metering equipment and its aims for the business prior to installation.

In June 2016 the utility supplies to site were installed with the Energy Deck equipment monitoring water and electricity use. The information accessible remotely will be used in future months to monitor, report and target energy use reductions for the project.
