Adding rows to the Energy Reporting tool - KBCN1441

After entering the first product, fill out the row beneath it with the details of another product and a row will automatically be added.

batch upload of HQM SAP XMLS - KBCN1428

There is a bulk HQM SAP xml upload feature at the start of an HQM assessment within the BREEAM Projects tool within the 'Homes' section.

Building assessed as part of a larger development - KBCN1313

Where the building under assessment forms part of a larger development and either a new or existing low or zero Carbon technology (LZCT) installation is provided for the whole site, then the amount of LZCT energy generation counted for in this issue, and subsequent CO2 emissions saved, should be proportional to the building’s energy consumption compared to the total energy consumption for the site.

Converting energy consumption into kWh/annum from new EU energy labels - KBCN1462

To convert the energy consumption from new EU energy labels into kWh/annum, the following guidance should be followed: Dishwasher: multiply kWh/100 cycles figure on EU energy label by 2.8 to get kWh/annum Washing machines and washer dryers: multiply kWh/100 cycles figure on EU energy label by 2.2 to get kWh/annum Ovens: multiply kWh/cycle figure on EU energy label by 286 to get kWh/annum
25 Aug 2023 - Correction to 'typo error' for dishwasher conversion factor - previously shown as 2.08, now corrected to 2.8

District heating connected after post-construction stage - KBCN1312

For HQM, at design stage, it may be acceptable to assume a network will be implemented and used by the assessed home, at completion if appropriate design-stage evidence demonstrates this, even if the system is not implemented at the time of the design-stage assessment. At post-construction, evidence would need to be revised and re-submitted based on what has happened in practice. In most cases the district heating network would need to have been installed and connected to, in order to use this system as part of the home’s energy calculations for the Energy and Cost issue, and to demonstrate installation of LZCTs in the Decentralised Energy issue. However, there is a possibility that time-frames could be flexible depending on the specific scenario being considered, which are judged on a case by case basis. To be considered, a technical query needs to be raised, with detailed information about the project including: location, size, whether it’s mixed-use or a phased development, type of network being connected to, time-frames of the connection and justifications for these, and the assurances that will be in place to ensure this happens in-practice. If it is not possible to provide this information during the design stage, this can be raised later but please be aware that there is a risk that credits achieved at design stage may be lost at post-construction stage, if the network is not connected to as planned. If this does happen, the ‘infrastructure’ criteria in the Decentralised energy issue may still be applicable if adequate infrastructure is installed by post-construction stage, which can be used to connect the home to LZCTs in the future, in line with any relevant criteria (e.g. feasibility study, CN4 etc.). In terms of how this works for BREEAM, it is possible that connection after post-construction could be acceptable, if the development is part of a larger or mixed-use project where the centralised services provision only becomes viable at a later phase and there are robust, legally enforceable routes to ensuring delivery of them to a set timeline. Evidence would need to be reviewed at post-construction stage on a case by case basis, in line with KBCN0267.

Heated common areas for homes - KBCN1390

A BRUKL is only required for the HQM calculation if it is already required by building control.

If heated common areas are not applicable to the assessment but the assessment tool is requesting inputs for them, please check your inputs for shared common areas in the 'Home details' and 'Energy and cost' parts of the tool.


HQM – Update to Building Regulations & SAP 10 - KBCN1553

We have incorporated the Building Regulations changes into HQM V6. HQM V6 (which has been published and is available for assessors to use) is compatible with SAP 10.  
30/10/23-Updated compliance note to confirm HQM V6 is compatible with SAP 10
