General Motors has a culture of environmental responsibility that enables creative thinking, innovation and business efficiency. The organisation is aware that sustainability can unlock business value and has identified three main drivers:
- Brand, reputation and corporate social responsibility
- Risk management and compliance with legislation
- Financial savings
Carbon Credentials has been helping General Motors to meet its carbon compliance and reporting requirements since 2011. Through this work, Carbon Credentials has developed a strong understanding of the opportunity to optimise energy performance in General Motors’ buildings, and the environmental, financial and reputational benefits this could deliver.
In recognition of the opportunity that exists at the non-manufacturing and dealership level to improve energy efficiency, General Motors asked Carbon Credentials for its support to develop a Retailer Energy Efficiency programme. Go Vauxhall, the largest Vauxhall retail group in London and the South East, was selected for the programme.
Stage 1: Energy audits to identify and quantify the opportunity
Carbon Credentials carried out a programme of energy audits across six dealerships of the Go Vauxhall retail group to identify technical and staff engagement opportunities to reduce energy usage. A number of specific opportunities for reducing consumption were identified, combined with a range of strategic areas for energy performance improvement.
Stage 2: Implementing the Pilot Engagement Programme: Driving for Efficiency
The audit programme confirmed that energy waste was high across the dealerships and that significant savings could be realised from engaging with staff at all levels. In order to demonstrate the direct financial benefits that could be achieved through staff engagement, a pilot engagement programme was initiated at Go Vauxhall Chislehurst.
Carbon Credentials worked collaboratively with key staff at the dealership, focusing on the following key activities:
- Site coordinators to help implement the programme
- Engaging with staff to improve end of day switch-off
- Branding & communications
- Analytics & reporting to monitor trends and enable a robust quantification of savings
- Tools for staff to help monitor consumption and rectify unexpected changes quickly
During the month-long pilot programme in June 2015, significant reductions were achieved in energy consumption.
- Overall a 23% reduction was achieved
- 36% reduction in electricity consumption in the Showroom building
- 11% reduction in electricity consumption in the Aftersales building
- 45% reduction in gas consumption in the Aftersales building
- If this was maintained for a year, cost savings of £8,600 would be achieved
75% of savings were achieved in the Showroom building, where overnight consumption was historically very high. The charts below present pilot and pre-pilot electricity profiles, illustrating the 63% reduction achieved overnight and 23% reduction during the day.
