Energy & Sustainability Compliance
Overview

SAP (Standard Assessment Procedure) calculations are the foundation of energy efficiency assessments for residential buildings, ensuring compliance with Building Regulations Part L1A and L1B.

• Customised SAP Assessments
  We tailor SAP assessments to align precisely with your building’s requirements, optimising energy efficiency while maintaining UK standards.
• Issuance of Energy Performance Certificates (EPCs)
  As part of our SAP service, we provide Energy Performance Certificates (EPCs), essential for verifying a building’s energy efficiency.
• Integration with SBEM and Energy Management
  Our SAP assessments extend to commercial properties with SBEM calculations. This creates a comprehensive overview of energy needs and identifies areas for improvement.

At Focus 360 Energy, our customer-focused SAP calculations ensure you meet regulatory compliance. We help you maximise energy efficiency and reduce costs.

SBEM (Simplified Building Energy Model) calculations are vital for non-domestic buildings. It helps them meet energy efficiency standards under Building Regulations Part L2.

• Thorough Energy Use Analysis
  We evaluate your building's energy use, identifying inefficiencies and providing recommendations to reduce consumption without compromising performance.
• Collaborative Approach to EPCs and Energy Audits
  Our SBEM assessments are often paired with EPCs and energy audits, offering a holistic view of your building’s energy performance and potential improvements.
• Guidance on Sustainable Design Adjustments
  We collaborate with developers and architects to design sustainable structures, reducing environmental impact and operational costs through energy optimisation.

Our SBEM assessments provide more than compliance support. We help clients improve efficiency and sustainability in their facilities.

Part O overheating assessments are critical in ensuring buildings are resilient against temperature extremes, a growing concern with climate change.

• Advanced Thermal Comfort Solutions
  We analyse overheating risks and implement strategies to maintain comfortable indoor temperatures year-round, minimising the need for artificial cooling.
• Comprehensive Ventilation Testing
  Overheating assessments are often combined with ventilation testing to create a balanced indoor environment that optimises temperature control and air quality.
• Future-Proofing for Climate Change
  Our assessments focus on long-term solutions that anticipate and adapt to changing climate conditions, ensuring lasting comfort and efficiency.

Our Part O assessments deliver effective, sustainable solutions for temperature management and thermal comfort.

Water efficiency is key to sustainable design and Part G compliance. Our Water Consumption Calculations ensure full adherence to Part G (Sanitation, Hot Water Safety and Water Efficiency) of the Building Regulations.

• Design-Stage Consumption Modelling We calculate the predicted water usage per person per day based on the flow rates of all proposed sanitary fittings (toilets, taps, showers, etc.).
• Compliance Documentation for Building Control We produce the necessary reports and documentation to demonstrate that the dwelling meets the maximum water consumption target (typically 125 litres/person/day, or 110 L/p/d for tighter planning requirements).
• Target-Setting Advice We provide expert recommendations on selecting efficient fixtures and fittings to easily meet and surpass required water efficiency standards. Our

PSI (Psi) calculations are essential for understanding thermal bridging, which impacts energy efficiency, building comfort and regulatory compliance.

• Precision Thermal Bridging Analysis
  Our team provides detailed calculations to identify and address thermal bridging, reducing unwanted heat loss and improving energy performance.
• Linked U-Value and Condensation Assessments
  PSI calculations are conducted in conjunction with U-value and condensation assessments, providing a complete thermal profile of the building.
• Energy-Efficient Building Design Recommendations
  We offer targeted suggestions to architects and developers, enabling them to design buildings with improved thermal efficiency and reduced energy costs.

Our PSI calculations help clients meet energy regulations and optimise building comfort and efficiency.

Condensation risk assessments are essential for preventing moisture-related damage and ensuring compliance with building standards.

• Thorough Moisture Control Analysis
  We assess all potential condensation areas, offering solutions that control moisture levels and protect against long-term damage.
• Linkage with U-Value and Ventilation Testing
  By conducting condensation assessments alongside U-value calculations and ventilation tests, we provide a comprehensive approach to moisture management.
• Enhanced Building Comfort and Durability
  Effective condensation management prevents mould and other issues, ensuring a healthy, comfortable indoor environment.

Our condensation risk assessments protect buildings from moisture-related issues. We enhance durability and support occupant well-being.

U-value calculations are crucial for understanding and enhancing a building’s thermal performance, ensuring compliance with Building Regulations Part L.

• Accurate Thermal Efficiency Assessment
  We measure thermal insulation effectiveness, identifying areas where improvements can significantly impact energy efficiency.
• Integration with Condensation Risk and SAP Assessments
  U-value calculations complement condensation and SAP assessments, forming a complete profile of a building’s energy performance.
• Clear Recommendations for Improved Insulation
  Our assessments provide clients with actionable advice on optimising insulation for reduced energy use and enhanced comfort.

Our U-value calculations help clients achieve thermal performance standards, supporting sustainable and compliant building designs.

Embodied and operational carbon transparency is the new frontier of sustainability. Our WLCA services ensure full adherence to emerging planning and regulatory requirements, such as those in the London Plan.

• A1-A5 Embodied Carbon Quantification
  We calculate the carbon emissions associated with the materials, construction, transport, and manufacturing processes of the entire building.
• B1-B7 Operational and In-Use Carbon
  We model the expected carbon emissions from the building’s operation (energy use, maintenance, repair) throughout its lifespan.
• C1-D Carbon Strategies and Benchmarking
  We provide reduction strategies to minimise the carbon footprint and benchmark the development against industry and regulatory targets for full transparency and compliance.
  Our WLCA services provide a detailed environmental footprint, moving beyond operational energy to deliver true whole-life sustainability and emerging compliance.

BREEAM is a leading global framework for assessing building sustainability. Our BREEAM Assessment Consultancy ensures full compliance with BRE standards, supporting the delivery of high-performance, low-impact developments.

• Pre-Assessment and Design Advice
  We undertake early BREEAM pre-assessments to identify realistic targets and guide the design team from the outset, embedding best practice across energy, water, materials, wellbeing, waste, and ecology.
• Evidence Management
  Our assessors manage the full evidence process, advising on compliant methodologies, gathering documentation, and ensuring all credits are met. This includes guidance on low-carbon design, responsible material sourcing, efficient systems, and best-practice site management.
• Certification Support
  We oversee the journey from concept to final certification, coordinating submissions with BRE and helping projects achieve the most appropriate rating to demonstrate verified sustainability performance.
• Future-Ready Outcomes
  A BREEAM rating positions your development ahead of regulatory change and supports enhanced sustainability, occupant wellbeing, and long-term operational efficiency.

Resource efficiency and waste minimisation are increasingly required for planning approval. Our Circular Economy Statements ensure full adherence to local planning policies and resource management best practices.
