What the work has covered

Practical energy work across varied building types

Energy work is rarely one-size-fits-all. Different buildings have different operating patterns, constraints, risks and opportunities.

Museums and cultural buildings

Energy management training and consultancy support for cultural organisations, including practical guidance on energy use, building services, environmental conditions and action planning.

Theatres and performance venues

Energy audit and carbon support for venues with complex usage patterns, public-facing operations and demanding building services.

Heritage buildings and estates

Practical energy and carbon work in buildings where conservation, fabric, use patterns and environmental requirements create additional constraints.

Factories and specialist facilities

Energy analysis and practical support for manufacturing, specialist facilities and operational buildings where process, plant and controls matter.

Offices and commercial buildings

Building energy audits, data analysis, controls review, lighting review and energy-saving recommendations for commercial premises.

Board and management reporting

Energy action plans, board-level reporting, SECR support and annual summaries to help decision-makers understand what matters.

Selected examples

Examples of the type of work behind Oxford Energy Services

These examples show the range of experience behind the current OES offer.

Cultural and heritage buildings

Museums and cultural organisations

Energy management training and consultancy support for museums and cultural organisations, including practical guidance on reducing energy use, using energy data and developing realistic action plans.

  • Managing environmental conditions
  • Understanding building services
  • Identifying operational improvements
  • Developing realistic action plans

Commercial sustainability support

Lush

Specialist consultancy support included work on energy and carbon issues across manufacturing and organisational activity.

This included practical analysis of energy use and broader sustainability considerations.

Compliance and reporting

ESOS and SECR

Experience includes ESOS assessments, Lead Assessor work and SECR support for a range of organisations.

The focus remains on practical energy improvement, not compliance for its own sake.

Software and tools

Pilio

Russell co-founded Pilio, which developed energy and carbon management software later sold to an Italian sustainability company.

This background informs the current OES approach: using data, tools and structured analysis to make energy management easier for building teams.

Building energy audits

Finding practical savings in real buildings

Previous building energy audit work has typically focused on identifying practical energy savings through data analysis, site inspections, plant and controls review, lighting review, heating optimisation, operational improvements and capital project prioritisation.

Why this experience matters

Practical judgement comes from seeing many buildings, many constraints and many failed assumptions

The value of the work is not only in calculations. It is in knowing what is likely to matter, what is probably being overstated, what needs checking first and what a facilities or management team can realistically do next.
