SBEM Calculations for Commercial Buildings

Fast, Compliant & Nationwide Service

Are you planning a commercial building project and need to meet Part L of the Building Regulations? At Assessment Hive, we specialise in delivering accurate, compliant, and fast SBEM Calculations to keep your development moving forward — on time and on budget.

Whether it’s a new build, extension, or refurbishment, we make energy compliance simple from start to finish.

✅ What Are SBEM Calculations?

Let’s start with the basics.

SBEM stands for Simplified Building Energy Model. It’s a government-approved method used to measure the energy efficiency of non-domestic buildings. This assessment is a mandatory requirement under Part L of the Building Regulations.

To comply, you must complete SBEM assessments at both:

• The Design Stage – before any work begins

• The As-Built Stage – once construction is completed

These calculations are used to generate:

• A BRUKL Report (Building Regulations UK Part L)

• A Non-Domestic EPC (Energy Performance Certificate)

Together, these documents prove that your building meets legal energy performance standards.

🕒 When Are SBEM Calculations Needed?

Understanding when you need SBEM Calculations is crucial.

Generally, they are required in the following situations:

1. New Commercial Builds

All new non-domestic buildings over 50m² must undergo SBEM assessments at both the design and completion stages.

2. Large Extensions to Commercial Buildings

If the extension is larger than 50m², or if the existing building exceeds 1000m² and energy systems are being updated, you’ll need a full SBEM assessment.

3. Conversions & Major Refurbishments

When a building changes use — for example, converting a warehouse into a gym — or undergoes substantial alterations, SBEM is typically required.

4. HVAC or Lighting Upgrades

If you’re replacing fixed systems like heating, cooling, ventilation, or lighting, SBEM Calculations help confirm compliance with updated efficiency standards.

🔍 Quick Tip: Not working on a commercial property? For residential projects, you’ll likely need SAP Calculations instead.

❓Frequently Asked Questions

What is the difference between SBEM and SAP Calculations?

SBEM is used for commercial buildings, while SAP is used for residential. Both assess energy efficiency to ensure compliance with Building Regulations.

How quickly can I get my SBEM report?

We usually complete reports within 2–4 working days, depending on the complexity of your project. Urgent? Contact us — we may be able to fast-track it.

What do you need from me?

We’ll need your:

• Floor plans, elevations, and sections

• Site orientation and address

• Construction specifications

• Details of heating, cooling, lighting & ventilation systems

We’ll guide you through it step by step.

What happens if my building fails the SBEM assessment?

If your initial calculation shows non-compliance, we’ll suggest clear, cost-effective improvements — such as insulation upgrades, more efficient lighting or HVAC systems — to help you meet the requirements.
