Bristol & the South West represents a thriving commercial market — Aztec West offices, life sciences in the harbourside, hotels and leisure across the city centre, and major industrial schemes around Avonmouth. Non-domestic schemes in this area need to demonstrate compliance with Part L Volume 2 of the Building Regulations — the part covering commercial, retail, hospitality, industrial and education buildings. Build Envelope is NDEA Level 4 and Level 5 accredited (EES/030713) and based in Worcester.
SBEM (Simplified Building Energy Model) is the government-approved BRE methodology for calculating the energy performance of non-domestic buildings. It produces the BRUKL Report (Building Regulations UK Part L) required by Building Control, plus the commercial EPC for marketing and MEES compliance.
The Bristol One City Plan and the Climate Emergency commitments set particularly clear expectations for non-domestic schemes — we model your specification against both Part L and the locally adopted policy thresholds so your scheme passes both Building Control and planning. Most of our work in this area is delivered in 5 working days from receipt of a complete information pack.
Whether you are at outline planning, detailed design, or pre-completion stage, we deliver a fully accredited SBEM and BRUKL package ready for Building Control submission and EPC lodgement.
SAP is desk-based, so we can work in parallel with your design team from anywhere. Most projects are turned around in 3-5 working days from receipt of drawings.
The fastest SBEM turnarounds happen when we receive the full information pack up front: building geometry, construction U-values, glazing schedule, HVAC spec (heating / cooling / ventilation / DHW), lighting design and controls, plus any renewables. Inputs that match the as-built reality reduce revisions late in the project.
If the design isn't complete yet, send what you have. We can run an early-stage SBEM using sensible assumptions and refine when the missing information lands — this is often the right approach when a planning deadline is tighter than the design programme.
Major commercial planning conditions in the South West frequently require Design Stage SBEM at submission. Get in touch early and we will work back from your submission date.
Local knowledge of each the South West LPA's Local Plan policies and planning condition templates for non-domestic schemes.

BRUKL stands for Building Regulations UK Part L. It is the formal output of an SBEM assessment that demonstrates a non-domestic building's compliance with Part L Volume 2.
Building Control will not sign off without the BRUKL Report, and a commercial EPC cannot be issued without it.
Yes for any new non-domestic building, significant extension (typically >100m² or >25% of existing floor area), major refurbishment, or change of use to a non-domestic class.
If you are unsure whether your project needs it, send us the planning description and we will confirm.
5 working days from receipt of a complete information pack is standard. For urgent submissions we routinely accommodate faster turnarounds.
SBEM is desk-based, so location within the South West makes no difference to delivery time.
Yes. We deliver SBEM across all 4 local planning authorities in the South West, working to each LPA's submission templates and planning condition wording.
Yes. Our dual NDEA Level 4 and Level 5 accreditation covers complex commercial buildings including district heating, CHP, high-rise mixed-use, and buildings with multiple zones and control strategies.
We identify the lowest-cost specification changes to bring BER ≤ TER — typically improvements to fabric U-values, glazing performance, HVAC efficiency, lighting controls, or addition of renewables.
We re-run the SBEM at no extra cost during the same project.
The commercial EPC is produced directly from the SBEM result. MEES currently requires E to let; the bar rises to C by 2027 and B by 2030.
Buildings assessed now that hit C or above are better positioned for future lettability and value.
5 day turnaround across the South West. Send us your drawings, HVAC schedule and lighting design — we'll quote within one working day and deliver a Building Control-ready BRUKL plus your commercial EPC.
