About Oxford Energy Services

Dr Russell Layberry

Environmental physicist. Building energy consultant. Practical problem-solver.

I run Oxford Energy Services to help building managers, facilities teams and operations managers understand and reduce energy waste in real buildings.

My work combines energy data analysis, site inspection and practical building-services understanding. The aim is not to produce long reports or generic sustainability language. The aim is to work out what is happening in a building, where energy is being wasted, and what actions are worth taking next.

Why I set up OES

Practical energy advice for buildings that need clear next steps

Many organisations know they need to reduce energy use, but they do not always have the time, in-house expertise or clear data to know where to start.

Oxford Energy Services exists to make that process clearer: looking at how a building is actually being used, what the energy data shows, where waste is happening, and which actions are realistic for the people managing the building.

Background

Energy, buildings and carbon — with a practical focus

01

Environmental physics

I am an environmental physicist with over 20 years’ experience in building energy, carbon and sustainability work.

02

University of Oxford

I spent 15 years as a researcher at the University of Oxford’s Environmental Change Institute, working on energy systems, building monitoring, modelling and demand response.

03

Pilio

I later co-founded Pilio, working on building energy audits, energy management, ESOS, SECR, carbon reporting, training and software tools.

04

Oxford Energy Services

OES now focuses on practical energy support for buildings, especially organisations with one building or a small number of buildings and no in-house energy specialist.

Professional credentials

Certified Energy Manager and AEE Individual Member

Russell combines scientific training, energy management experience and practical building-services understanding.

How I look at a building

Several angles at once

My background is both technical and practical. I am a physicist by training, with hands-on building-services experience including electrical installation training, heat pump training and F-Gas certification.

This means I can look beyond the meter readings and consider how the building is actually being used, how the systems are controlled, and what a busy facilities team can realistically do next.

What the energy data is showing
How the building is being used
Whether controls and plant make sense
Which recommendations are practical
Whether contractor proposals are credible
What the team can do next

What OES focuses on now

Practical energy support for buildings

Oxford Energy Services now focuses on practical energy support for organisations with one building or a small number of buildings, where energy costs matter but there is no in-house energy specialist.
