on-time and in a cost-effective manner as well as identifying potential carbon savings of just over 1,173 tCO2
annually with an annual financial benefit of over £270,000. The potential energy savings identified amounted to 3,840,113kWh, or just over 20% of the group’s annual energy consumption.
The Stewart Milne Group is a leading national construction company, with a particular focus on home building. The group has offices in Aberdeen, Edinburgh, Glasgow, Oxford and Manchester with building sites spread over the country. The group also manufactures timber systems and specializes in off-site construction for affordable housing, accommodation blocks, hotels and schools. The timber systems are manufactured in factories in Aberdeen and Oxford. The group has designed, developed and built its own five-star carbon neutral home, The Sigma Home.
Since its establishment in 1975, the group has grown to employ over 800 people, achieving a turnover of over £200m.
The Energy Savings Opportunity Scheme (ESOS) regulations were introduced to make it mandatory for large organisations to undertake energy audits of 90% of their energy consumption every 4 years. The first phase of these regulations had a qualification date of the 31st December 2014 and a compliance date of the 5th December 2015.
Due to the number of employees in the group and the turnover of the group, Stewart Milne Group met the qualification criteria and were required to undertake an audit of 90% of their total energy consumption before the compliance date.
How did esave help them?
Inverness based consultancy esave were appointed by the Stewart Milne Group to assist them in undertaking their ESOS compliance duties, providing support and assistance in;
- the gathering of energy consumption data and in determining what the 90% of their energy consumption consisted of,
- carrying out the required energy audits,
- completing the compliance submission and
- providing ESOS Lead Assessor sign off
The whole process was overseen by esave’s fully qualified ESOS Lead Assessor to ensure all activities carried out were compliant with the regulations.
The Stewart Milne Group’s total energy consumption in the qualification year was determined to be just over 18,500,000kWh and comprised of approximately:
- 40% used on construction sites,
- 26% by company vehicles and grey fleet and
- roughly 24% at the Aberdeen and Oxford sites
A sampling approach is allowed under ESOS regulations where sites with similar activities, operations and types can be sampled to reduce the audit burden. For this reason, a sample of the building sites was undertaken and it was determined that the Oxford and Aberdeen sites could be sampled due to the similarities in operations.
esave carried out audits at the Aberdeen facility as well as the building site in Westhill. In addition, a Business Transport Energy Assessment was carried out by the energy saving trust and this was used as part of the compliance pack.
What was the outcome
With esave’s support the Stewart Milne Group achieved compliance on-time and in a cost-effective manner as well as identifying potential carbon savings of just over 1,173 tCO2 annually with an annual financial benefit of over £270,000. The potential energy savings identified amounted to 3,840,113kWh, or just over 20% of the group’s annual energy consumption.
'“I would like to thank the esave team for their help and support in both the understanding and pulling together of our energy consumption data.
They were helpful and proactive, collaborating with our team and ensuring we got all the necessary information validated and submitted on time.”
