NDEA-accredited SBEM and BRUKL Report delivery for non-domestic schemes in Warwickshire.

SBEM Calculations Warwickshire commercial non-domestic

Warwickshire represents a growing commercial sector — logistics warehouses along the M1/M6/A5 corridors near Rugby, business parks around Warwick and Leamington, hotels and visitor accommodation across the Stratford district, and rural commercial conversions in the heritage settings. 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 Warwick District Local Plan, Stratford-on-Avon Core Strategy, and Rugby Borough Local Plan 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.

Part L Vol 2 compliance

BER ≤ TER
Building Emissions Rate must be lower or equal to the Target Emissions Rate — Part L 2021 Vol 2, England
Commercial EPC matters for MEES. Minimum Energy Efficiency Standards already require an E rating to let. The bar is rising to C (2027) and B (2030). Schemes assessed now should target C or above to protect lettability and investment value.
Levels 4 & 5 accreditation. Most standard commercial buildings need NDEA Level 4. Complex buildings — district heating, CHP, high-rise mixed-use — need Level 5. We hold both, so we can assess any building type.

How a SAP calculation runs from drawings to EPC.

SAP is desk-based, so location within Warwickshire makes no difference to delivery. We typically issue Design Stage in 3-5 working days from a complete information pack, with urgent turnarounds available on request.

01
Information gathering
We send a project information pack — geometry, glazing schedule, HVAC system spec, lighting design, controls, renewables. Accurate inputs = accurate result.
02
iSBEM modelling
We model the building in iSBEM software against Part L 2021 Vol 2. If the spec doesn't pass, we identify the most cost-effective changes to get BER ≤ TER.
03
Spec optimisation
Where the design margin is tight we model alternative spec options — fabric, glazing, HVAC efficiency, controls, renewables — so you can pick the lowest-cost compliant route.
04
BRUKL & EPC issued
Final iSBEM run produces the BRUKL Report for Building Control and the commercial EPC. We lodge the EPC and provide all documentation needed for sign-off.

What we need from you to start your Warwickshire SAP.

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 Warwickshire frequently require Design Stage SBEM at submission. Get in touch early and we will work back from your submission date.

SBEM information checklist

Architectural drawings Plans, sections, elevations, site plan — PDF or CAD. Need to extract geometry, zones and orientations.
Construction U-values Wall, floor, roof and party-wall build-ups. Manufacturer data sheets are ideal — or send construction notes and we'll calculate.
HVAC strategy Heat source, cooling, ventilation system, DHW, controls. Mechanical schematics or designer's specification.
Lighting design Lamp type, luminous efficacy, controls (occupancy / daylight dimming) per zone.
Glazing schedule U-value, g-value, frame factor for each window / curtain wall / rooflight.
Renewables (PV / heat pumps / etc.) kWp, orientation, overshading for any photovoltaic, solar thermal, ASHP or GSHP systems.

Common questions about SBEM Calculations in Warwickshire.

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 Warwickshire makes no difference to delivery time.

Yes. We deliver SBEM across all 5 local planning authorities in Warwickshire, 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.
