Erratum – NCV7 – Ene 08 Installed controls - KBCN1812

There is a printing error in the following: UKNC V7 Ene 08 Table 6.18 INC V7 Ene 08 Table 43 The correct options for Installed controls for space heating are:

Control type	Control functionality	Points awarded
Heat generator output – heat pumps	Multi-stage control (e.g. several on/off compressors)	1
	Variable control (e.g. hot gas bypass, inverter frequency control)	2

GN49 International Ene 01 calculation methodology guidance - KBCN1749

Latest version: v0.0, July 2025 Guidance Note 49 (GN49) gives background information on the methodology for determining the number of credits achieved for energy performance under the Ene 01 assessment issue for BREEAM International NC V7. The Ene 01 methodology uses a triple metric approach that addresses energy demand for heating and cooling, primary energy consumption, and carbon dioxide emissions. The aim of using this approach is to minimise the energy consumption and carbon emissions from regulated energy uses and to maximise the use of low carbon energy sources. Guidance Note 49 also includes the adjustment factors that are applied to uplift the reference metrics in Ene 01 for BREEAM International NC V7. It describes the methodology for determining the factors and the application process to have a country’s adjustment factor added or updated.

Independent third party – clarification on the definition - KBCN1805

For the purposes of BREEAM, sister companies or parent companies cannot be considered as third parties.  To be classed as an independent third party, there must be no professional connection or relationship between the LCA consultant/energy assessor, or their company, and the verification body. The third-party verifier must be independent of the LCA or energy assessor and demonstrate impartiality (for general principles, see ISO 17029). To qualify as a third party, the verifier must belong to an organisation not involved in the project and must not provide advice to the project, as this could compromise their impartiality during verification.
