NABERS UK Design for Performance Fact Sheet
The UK has a design-for-compliance culture which has led to the well-known ‘performance gap’ that exists between original design intent and how a building truly performs in-use. Design for Performance is a process that overcomes this, where a developer or owner commits to design, build and commission a building to achieve a targeted NABERS Energy rating.
If you are a developer or owner, you can register any new office development or major refurbishment by signing a Design for Performance Agreement. Your target NABERS Energy rating must be 4.0 stars or above.
Example Simulation Report
This report is an example simulation report that demonstrates the key features of a simulation report compliant with the requirements of a Design for Performance Agreement. A Simulation Report should provide a realistic estimate of the operational energy performance of the project. As a part of the Independent Design Review process, it is a requirement to provide a Simulation Report to the selected Independent Design Reviewer for evaluation. More information on the sections that a simulation report should contain, and its format can be found in the Guide to Design for Performance

NABERS UK The Rules - Energy for Offices v1.2 (previous version - Base Building only)
NABERS UK currently offers one type of rating, NABERS Energy for Offices, which measures and rates the Base Building energy efficiency of an office. An accredited NABERS Energy for Offices rating is awarded when the Scheme Administrator certifies a rating completed by an Assessor.
The purpose of this document is to give clear requirements for Assessors when they are evaluating offices for their energy usage with the goal of providing a NABERS rating. It is intended that this document, be read and used alongside NABERS UK The Rules – Metering and Consumption.
Any ratings performed using the previous versions of the Rules:
- NABERS UK The Rules – Energy for Offices v1.2 (base building only)
- NABERS UK The Rules – Metering and Consumption v1.1 (base building only)
must apply for certification by 31st July 2023. Any Ratings using these Rules documents that are submitted after this date will be rejected.

trigeneration system (“a system”). It provides guidance for Assessors where such systems are present either onsite or offsite relative to the rated premise and the metering and measurements of all scenarios.
The methodology presented in this document outlines how to use the calculator to determine the energy inputs to be entered in the NABERS rating input form, based on the apportioning of energy and the allocation of greenhouse gas emissions as determined by the calculator.
This Ruling will supersede the Interim Methodology for the treatment of Cogeneration and Trigeneration Systems in NABERS ratings (version 1.1).
Code of measuring practice
The purpose of the Code is to provide succinct, precise definitions to permit the accurate measurement of buildings and land, the calculation of the sizes (areas and volumes) and the description or specification of land and buildings on a common and consistent basis. This may be required for valuation, management, conveyancing, planning, taxation, sale, letting, or acquisition purposes.
