Smart system
saves energy

British Land has installed a new energy management system at Broadgate Tower, 10 and 20 Triton Street and Ropemaker Place, following a successful pilot at our Head Office, York House.

The new energy system at York House saved £28,000 over an eight month period

We are working with our occupiers to install it in a further four buildings over the next few months, with all of our multi-let managed offices and three of our shopping centres installing it by March 2011.

The new smart metering and energy management system, provided by EP&T Global, uploads electricity and gas data automatically to a central system every 15 minutes. EP&T’s remote monitoring service highlights opportunities for the Building Engineer to optimise the central heating and cooling plant, financially quantifying the impact of each action. A monthly report highlights the financial impact of actions completed, and provides an ongoing report of outstanding actions.

Head of the Business Group at British Land, Justin Snoxall, comments: “Where appropriate, we provide the initial capital investment, recovering this through utility cost savings generated through energy use reductions.”

Impacts of the energy management system at York House:

  • 38% reduction in base-building energy use
  • £28,000 savings over an eight-month period
  • Prompt identification of broken sensor that had been causing constant gas use for heating
  • Reprogramming Building Management System to fix constant gas use for cooling
  • Introduction of economy cycles and new set points
  • Better use of external air to provide free cooling.

In Australia, EP&T equipment is installed at over 500 sites, reducing greenhouse gas emissions by more than 60,000 tonnes over the last year and saving businesses more than AU$14 million in electricity, gas and water costs. EP&T is so confident of the effectiveness of its system, that it offers guarantees for the savings in common parts and central heating and cooling plant.
