Carry out Building Regulations compliance checks of as-designed and as-built new-build non-dwellings using the Simplified Building Energy Model SBEM
This element equips learners with the ability to perform statutory compliance checks for new non-domestic buildings using the Simplified Building Energy Model (SBEM), ensuring adherence to Part L of the Building Regulations and EU directives. It covers interpreting as-designed and as-built specifications, identifying factors that influence energy performance, and verifying that the building meets the required Target Emission Rate (TER). Proficiency is essential for energy assessors to certify compliance and issue Energy Performance Certificates.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The ABBE Level 4 Diploma in Non Domestic Green Deal Advice covers the principles and practices of providing Green Deal advice for non-domestic buildings, including energy efficiency assessments, recommendations, and compliance with UK regulations. It equips students with skills to advise clients on reducing carbon emissions and energy costs in commercial properties.
Topic Overview
The ABBE Level 4 Diploma in Non Domestic Green Deal Advice is a specialised qualification for professionals aiming to provide energy efficiency advice to commercial and industrial building owners. It covers the legal framework, energy assessment methodologies, and the process of recommending cost-effective improvements. This diploma is essential for those working in the built environment sector, as it aligns with UK government targets for net-zero carbon emissions by 2050.
Students learn to conduct energy audits using approved software like SBEM, interpret results, and produce Green Deal Advice Reports (GDARs). The course also emphasises the 'Golden Rule'—ensuring that energy savings outweigh the cost of improvements—and the importance of tailoring advice to non-domestic buildings' unique characteristics, such as multiple tenancies, complex HVAC systems, and variable occupancy.
This qualification fits within the broader context of building energy performance regulations, including Part L of the Building Regulations and the Minimum Energy Efficiency Standards (MEES). It prepares students to advise clients on compliance, funding options, and long-term sustainability strategies, making it a valuable credential for energy consultants, surveyors, and facilities managers.
Key Concepts
Core ideas you must understand for this topic
- →Green Deal Golden Rule: The cost of energy efficiency measures must be covered by energy savings over the plan's lifetime.
- →SBEM and DSM: Software tools for non-domestic energy assessment, with SBEM for simpler buildings and DSM for complex ones.
- →Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs): Required documentation for non-domestic buildings, with DECs for public buildings over 250 m².
- →Energy Efficiency Measures (ECMs): Improvements such as lighting, HVAC, insulation, and renewables, each with specific payback periods and carbon savings.
- →Part L Compliance: Building Regulations requirements for energy performance in new and existing non-domestic buildings.
Learning Objectives
What you need to know and understand
- Understand the requirement for new Buildings other than dwellings to be compliant with the energy efficiency requirements of EU and national legislation, Understand the role of the energy assessor in checking compliance of new buildings other than dwellings with the energy efficiency requirements of the Building Regulations, Understand the factors that affect the compliance of new buildings other than dwellings with the energy efficiency requirements of the Building Regulations, Be able to carry out a compliance check of new buildings other than dwellings with the energy efficiency requirements of the Building Regulations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate selection and application of SBEM methodology, including correct zoning and input of building fabric, services, and lighting data.
- Expect evidence that the learner can differentiate between as-designed and as-built compliance checks, adjusting inputs accordingly for materials, systems, and construction variations.
- Credit clear justification of compliance by comparing the Building Emission Rate (BER) with Target Emission Rate (TER) and explaining any shortfalls or improvements.
- Require demonstration of understanding how to incorporate low and zero carbon (LZC) technologies and their impact on compliance, including renewable energy systems.
- Assess ability to identify and apply relevant notional building specifications and NCM Activity Database entries for the specific building type.
Assessment Guidance
Guidance for achieving higher grades
- 💡When performing a compliance check, always cross-reference the client’s design and construction documents with the actual building specifications to ensure accurate inputs.
- 💡Practice using SBEM with various building types to become familiar with the software’s nuances, such as handling complex geometry or mixed-mode ventilation systems.
- 💡In the assessment, clearly document your decision-making process, including assumptions and data sources, to demonstrate thoroughness and adherence to conventions.
- 💡Stay updated with amendments to Part L and approved documents, as regulatory changes directly affect compliance criteria and may be tested.
- 💡Always use correct terminology: 'Green Deal Advice Report' not 'energy report', and 'energy efficiency measure' not 'improvement'.
- 💡For calculation questions, show all steps and include units. Partial marks are awarded for correct method even if arithmetic is wrong.
- 💡When evaluating, give balanced arguments with evidence from the scenario. Conclude with a justified recommendation.
Common Mistakes
Common errors to avoid in your coursework
- Confusing as-designed and as-built stages, leading to incorrect input assumptions such as using design U-values for constructed elements without verification.
- Misinterpreting SBEM zoning rules, resulting in incorrect area measurements and inaccurate energy calculations.
- Failing to account for thermal bridging, air permeability, or solar gain in the model, which can significantly skew results.
- Overlooking the need to use the appropriate version of SBEM software and its associated databases, causing non-compliance with current regulations.
- Misconception: The Green Deal is a grant. Correction: It is a loan repaid through energy bills, not a grant. The Golden Rule ensures savings cover repayments.
- Misconception: Non-domestic energy assessment is the same as domestic. Correction: Non-domestic uses different software (SBEM/DSM) and considers complex factors like zoning and variable occupancy.
- Misconception: An EPC and a DEC are interchangeable. Correction: An EPC rates the building's fabric and services, while a DEC shows actual energy consumption. DECs are required annually for certain public buildings.
Revision Plan
How to revise this topic in 1–2 weeks

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A non-domestic building has a total floor area of 2,500 m². The annual energy consumption is 450,000 kWh for gas and 120,000 kWh for electricity. Calculate the Energy Use Intensity (EUI) in kWh/m²/year and state whether this is typical for an office building (typical EUI 150-250 kWh/m²/year).
- 1.Step 1: Convert electricity consumption to primary energy if needed (not required here, use delivered energy). Total energy = 450,000 + 120,000 = 570,000 kWh.
- 2.Step 2: Divide total energy by floor area: EUI = 570,000 / 2,500 = 228 kWh/m²/year.
- 3.Step 3: Compare to typical range: 228 kWh/m²/year falls within the typical office range of 150-250, so it is typical.
Question: Describe the key steps in conducting a Green Deal Advice assessment for a non-domestic building, including the role of the Green Deal Advice Report (GDAR).
- 1.Step 1: Conduct an energy assessment using approved software (e.g., SBEM) to determine current energy performance.
- 2.Step 2: Identify cost-effective energy efficiency measures (ECMs) such as LED lighting, HVAC upgrades, or insulation.
- 3.Step 3: Prepare a Green Deal Advice Report (GDAR) detailing the assessment, recommended ECMs, estimated savings, and payback periods.
- 4.Step 4: Provide the GDAR to the client and explain the Green Deal financing options, including the Golden Rule (savings must exceed costs).
