Building Energy Audits & Energy Management Support

Energy Efficiency.
Engineered by Science.

Practical building energy audits for lower bills, less waste and better control of your building.

Oxford Energy Services is an independent building energy consultancy helping building managers, facilities teams and operations managers understand where energy is being wasted — and what to do about it.

If you manage a building and have been asked to reduce energy costs, improve energy performance or report progress to senior management, OES can help you get a clear, practical plan.

No jargon. No generic net zero waffle.

Clear energy diagnosis for real buildings

The focus is simple: less energy waste, lower bills and better control of your building.

OES audits are designed for organisations that need useful recommendations, not a long report that sits on a shelf.

For organisations comparing energy audit companies or consultancies, the important question is not simply who can produce a report. It is who can investigate how the building is actually operating, interpret the energy data and turn the findings into practical priorities.

Russell’s combination of scientific research, software development and practical building experience means he can understand the physics, interrogate the data, inspect the systems and decide which actions are genuinely worth pursuing.

Services

Start with an audit. Continue with practical support.

Building Energy Audit

One building. Practical diagnosis. Clear next steps.

A building energy audit is the best starting point if you are unsure where energy is being used or wasted.

  • Electricity and gas use
  • Half-hourly electricity data, where available
  • Night load and out-of-hours consumption
  • Heating, lighting and controls
  • Plant and operational issues
  • Quick wins and capital measures worth investigating

You receive a concise summary of what is happening in the building, where the main opportunities are and what should be done next.

Energy Management Support (Retainer)

Practical support without employing a full-time energy manager.

Many organisations do not need a full-time energy manager, but they do need someone experienced who can look at the data, sense-check proposals and help keep energy actions moving.

  • Energy data review
  • Night-load checks
  • Quote and proposal review
  • Advice on heating, lighting, controls and solar PV
  • Energy action plans
  • Board-level energy updates
