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
