What’s actually changing, and what it means for your project
BRE has published the summary of changes for BREEAM New Construction V7.1, due to land as the next iteration of the V7 standard. If you’re mid-design, mid-delivery, or about to register a project, the good news is this isn’t a reset. It’s a tidy-up with two genuinely significant rewrites buried inside it – and if you’re running a Man 01 or Man 04 strategy right now, those two are worth your attention immediately.
Here’s what’s changing, organised the way you’ll actually need to use it: by what it means for project teams at each stage, not just by issue number.
The two changes that aren’t just tidying up
Most of V7.1 is refinement. Two issues are not.
Man 01 Project brief and design has been rewritten around Soft Landings principles. The headline addition is a mandatory project delivery workshop at Concept Design, with a defined agenda: shared performance objectives, measurable success criteria, and a performance risk register that gets tracked from that point on. Intermediate workshops at later design stages keep those objectives live rather than letting them quietly drop off the brief, and a structured review at completion checks what was actually delivered against what was promised. If your current process treats the brief as a document you write once and file, this is the bit to flag to your client and design team now – not at Stage 4.
Man 04 Commissioning and handover has had a similar overhaul. There’s now a required commissioning workshop early in design, a full commissioning plan, commissionability reviews, and clearer specification and methodology requirements running right through to testing and handover. The role of commissioning manager has been tightened too – a relevant degree-level qualification plus three years’ experience, or CSA/ASHRAE membership, rather than something looser. One single commissioning manager now needs to lead the process, with manufacturers and specialist subcontractors feeding in rather than running their own parallel commissioning. For teams who’ve treated commissioning as something that gets sorted out on site in the final weeks, this update is effectively asking you to start that conversation at RIBA Stage 2.
Both rewrites point the same direction: BRE wants performance commitments made early and tracked properly, not assumed and discovered to be missing at handover. That’s a principle we’d back regardless of the credit – early technical input is cheaper than late redesign, every time.
Energy: a few changes worth checking against your current model
Several Ene issues have had genuine technical substance added, not just wording fixes.
- Ene 02 changes the rounding convention for credit boundaries (OEPnc × 7 now rounds up rather than down), meaning one credit becomes achievable as soon as performance is any amount above the 2.5× benchmark, rather than needing to clear a higher threshold. Projects sitting just under the old boundary may now qualify.
- The approved energy modelling software list has been dropped from Ene 02 in favour of pointing assessors to GN53 – worth checking that your modelling platform of choice is still clearly covered.
- Ene 04 now requires criterion 3 to be achieved before the two-credit fabric performance optimisation tier is available – a sequencing change that matters if you were planning to claim fabric credits independently.
- Ene 07 has had its battery storage scoring split out from “other systems,” with points recalculated accordingly – if flexible demand response formed part of your strategy, it’s worth re-running the numbers rather than assuming the old split still applies.
- For Northern Ireland projects, the BRUKL calculator and NI scoring path are now built in, removing the previous disclaimer about NI not being assessed.
None of this changes the fundamentals of good low-carbon design. It does change where the credit boundaries sit, which is exactly the kind of detail that’s easy to miss until an assessor flags it at Stage 5.
Health and wellbeing: testing windows and weather files
A few changes here affect what gets specified and when testing happens, rather than the underlying performance ask.
Hea 02 has been renamed from “Artificial light” to “Electric light,” and the flicker requirement at full load has moved out of the prerequisite for UK and EU projects, since compliant products now meet it by default. Outside the EU regulatory area, the prerequisite remains, so international teams should check this carefully before assuming it no longer applies.
Hea 04 now requires indoor air quality testing to be carried out by a defined “suitable IAQ professional,” and post-construction testing can now happen up to two weeks after occupancy rather than needing to be done immediately – a small but useful practical concession for handover scheduling.
Hea 05 brings in CIBSE’s 2025 weather files for UK thermal comfort assessments, with future weather file selection now following a risk-based approach rather than a flat rule. International projects that are mechanically ventilated can now use a 15-year lifespan option instead of defaulting to the full 50-year future weather file – relevant if you’re assessing overheating risk on a shorter-life asset.
Water, transport, materials and waste: mostly clarity, one genuine number change
Wat 01 absorbs a long list of existing Knowledge Base guidance directly into the methodology – flow rates for mixed taps, multi-head showers, urinal flushing frequency, and time-limited showers and taps are now all explicit rather than something you had to dig out of KBCN articles. If your QS or M&E team has previously relied on bookmarked KBCN guidance for these calculations, it’s now in the manual itself.
Tra 02 swaps “EV charging stations” for “EV charging points” throughout, to remove ambiguity about whether the credit is counting plug points or bays – worth a check if your transport statement uses the old terminology.
The one number to flag in Materials: Mat 01’s embodied carbon benchmarks have been uplifted by 10%, in line with the UK Net Zero Carbon Buildings Standard. If you’ve got an LCA in progress using the current benchmarks, this is the change most likely to actually move your score, not just your wording.
Land use, ecology and pollution: sharper definitions, same intent
Lue 02 and Lue 03 add new platform questions around biodiversity-sensitive sites and the role of the Ecological Clerk of Works, alongside new definitions for survey and field sampling techniques. Pol 04 introduces a formal definition of bird collision risk linked to lighting design, tying nighttime lighting assessment more explicitly to ecological outcomes in Lue 03. Pol 05 swaps “noise-sensitive areas” for “noise-sensitive receptors” throughout, with noise level clarified against ISO 1996 and BS 4142:2014 – a useful tightening for anyone who’s had to argue definitions with an assessor before.
What we’d actually do about it
If you’re at brief or concept stage on a New Construction project, build the Man 01 delivery workshop and Man 04 commissioning workshop into your programme now – both are designed to happen early, and holding them later defeats the point.
If you’re mid-design, the changes most likely to bite are the Mat 01 embodied carbon uplift and the Ene 02 rounding change – both are numerical, and both are worth re-running rather than assuming your current figures still clear the bar.
If you’re heading toward testing and handover, check your commissioning manager’s credentials against the new competency requirements, and note the slightly more forgiving two-week window for post-occupancy IAQ testing.
None of this should cause alarm. It’s a standard maturing in the direction it said it would – better-tracked performance commitments, tighter commissioning, and a steady alignment with Refurbishment and Fit Out V7. The detail is what changes outcomes, and that’s exactly where we spend our time.
