A sustainable approach

GSH uses a unique integration platform that closes the loop between energy management, building controls and engineering service provision, keeping energy waste to a minimum

Sustainable consumption reduction is the ability to monitor and effect change promptly. Energy-led engineering can ensure occupant thermal comfort while delivering energy efficiency and maximising the useful life of assets.

The approach focuses its operational delivery on a technical and cultural approach, engaging both enhancements in technological systems but also embedding this approach both across GSH and the wider client base.

To deliver this, GSH employs a unique integration platform which closes the loop between energy management, building controls and engineering service provision. It enables the live streaming of energy data so that we can identify energy wastage at asset level and resolve unpredicted usage.

Alerts and job details are sent out via SMS and email, and fixes are carried out in the GSH energy controls centre via a remote dial in function.

It is not only remote dial-in facilities that are performing as part of the GSH service – alerts can be sent to building managers and energy managers assigned to the specific sites.

Site knowledge and energy management controls expertise provide a seamless process to carbon reduction and asset management. The synergy created by energy-led engineering services galvanises a trusted partnership between GSH and its clients.

This pioneering product has been developed by our internal team and is the only one of its kind in the industry.

It is an innovative and forward-thinking solution that has been developed to provide our clients with a way to automate and remotely manage a range of services in an efficient, cost-effective and environmentally friendly way.

Energy-led engineering solutions benefits include:

  • Intelligent real-time monitoring and targeting at asset level;
  • Reduce site visits through remote diagnostics and first-time fixes;
  • Prioritisation of focus areas;
  • Proactive energy management;
  • Reduce energy consumption;
  • Maximise asset performance;
  • Life-cycle investment analysis.

A case study

Working alongside managing agent Cushman & Wakefield, GSH agreed a full M&E and energy performance contract in 2007, which has now been extended to 2020. The contract covers all technical service provision and energy management services across the UK portfolio. This also includes a guaranteed 17 per cent energy saving.

GSH are responsible for more than 380 high street branches, head office properties and business-critical data centres located throughout the UK. GSH was chosen to develop, manage and implement the UK energy efficiency strategy and assist in becoming a UK industry leader in terms of energy management.

Service delivery

Multiskilled forensic audits and building energy modelling is used to assess projects and forecast savings.

Projects delivered include energy efficient AC, lighting and boilers across the portfolio, BMS upgrades and optimisation, a retail BMS control solution, AHU optimisation and lighting control solutions.

A key part of the strategic energy management partnership embedded into the GSH delivery model is EMAP. This is the GSH energy monitoring and targeting application that links energy and M&E in a combined energy-led maintenance.

GSH runs a full bureau service, which ensures cost management and avoidance through bill validation, invoice, data and tariff cross-referencing and utility procurement.

Variation and reporting is delivered through the GSH Energy and controls centre. Our portal and dashboard offerings allow the customer to view progress to date and any specific reporting requirements. 

GSH have also managed and assisted NAG with carbon reduction commitment, carbon disclosure project and BS EN 16001 reporting, and a portfolio-wide AMR strategy. GSH continue to bring innovative ideas to the customer, including our Advanced Building Energy Management System (ABEMS) solution for retail and small office environments.

Through the delivery of an innovative integrated energy-led engineering service for NAG’s critical sites, offices, data centres and the entire retail network across the UK, GSH has driven consumption savings beyond the 17 per cent target. Commenting on the alliance with GSH, Dan Moore, head of property at NAG, said: “We have a strong and evolving CSR programme. Over the past five years we have worked closely with GSH and it has played a vital role in helping us to achieve our targets.”

Results to date:

  • Electricity cost saving £5,092,680 (28,492 tonnes of CO2 saved);
  • Gas cost saving £1,735,368 (12,640 tonnes of CO2 saved);
  • Total cost saving £6,828,048 (41,132 tonnes of CO2 saved);


  • Energy Led Maintenance – Combined Energy & M&E service delivery;
  • Risk minimisation against volatile energy prices and reliance on fossil fuels;
  • Reduction of carbon emissions and their related effect on the environment; 
  • Good corporate social responsibility.
