BREEAM Ene 01 — Reduction of Energy Use and Carbon Emissions
How BREEAM Ene 01 (reduction of energy use and carbon emissions) is assessed, the evidence your assessor needs and how to secure the credits early. Fixed-fee UK
BREEAM Ene 01: reduction of energy use and carbon emissions
Ene 01 is usually the single most valuable BREEAM credit. It compares modelled energy demand, consumption and carbon emissions with a notional building, so early energy modelling decides how many credits you can reach.

What Ene 01 assesses and the evidence needed
| Requirement | Typical evidence |
|---|---|
| Fabric and services performance | Energy model output (SBEM or dynamic modelling) |
| Low and zero carbon technologies | Feasibility study at concept stage |
| Operational energy prediction where targeted | Prediction report and design workshop record |
Exact criteria and credit numbers depend on the scheme and manual version your project is registered under. Your assessor confirms them at pre-assessment.
How to secure Ene 01 without extra cost
- Agree the target at pre-assessment, before RIBA Stage 2.
- Give the responsible designer or contractor a clear evidence list.
- Check the evidence at design stage so nothing is lost at post-construction review.
