A new building or regulated building work
Use SBEM and BRUKL assessments for relevant non-domestic Part L work. The model connects architecture, activity zones, fabric, lighting and M&E systems; complex cases may need an approved dynamic route.
For non-domestic projects
The right assessment for the commercial building
SBEM, BRUKL, EPCs, overheating modelling and planning evidence scoped around the building, systems and purpose.
Begin with the purpose
The reason for the assessment matters as much as the building type. Start with the output required and the project’s design or occupancy stage.
An EPC, a Building Regulations report and a planning energy statement answer different questions. Geometry, use, services complexity, property boundaries and the approval brief determine the assessment route. Briary reviews those facts before confirming the modelling or survey scope.
Four common assessment routes
A certificate for the property
A commercial EPC records the building’s energy rating through the appropriate accredited assessment and lodgement process. Existing properties normally require survey access and evidence of the fixed services.
An overheating or comfort question
For relevant naturally ventilated spaces, TM52 modelling can examine room-level comfort and design options. Building use, operating strategy and the client or planning brief determine the correct criteria.
Planning or a wider sustainability brief
An energy statement addresses the site’s planning requirements. BREEAM energy evidence follows the appointed assessor’s brief. Neither is automatically replaced by a BRUKL report.
Clear evidence for the agreed purpose
New construction
SBEM modelling, design and as-built BRUKL reports, and related Part L advice.
Certification
Commercial EPC support through the appropriate accredited assessment route.
Planning and assessment support
Energy statements and defined energy evidence for wider project requirements.
Getting started
A useful first information pack
Building and purpose
Address, use, approximate floor area, new or existing status, proposed works, tenancy or certification boundaries and the exact output requested.
Architecture and systems
Current plans and sections, room uses, fabric and window information, heating, cooling, ventilation, hot water, lighting and controls. Identify atria, mixed uses or unusual systems.
Records and access
Existing EPC or BRUKL information, services records, planning conditions and programme. For an existing-building survey, include access arrangements and a site contact.
Frequently asked questions
Can one assessor cover a mixed-use building?
The scope depends on the uses, certification requirements and project boundaries. We review the arrangement before confirming.
Can you model a shell-and-core project?
Yes, where an appropriate methodology and clear landlord or tenant assumptions can be established.
Do you undertake operational energy audits?
Not as a standard service described here. We will be clear if a request needs another specialist.
