Our Services

We offer a broad range of services, including Energy Performance Certificates (EPCs), SAP calculations, SBEM calculations, U-Value assessments, and water efficiency calculations. Our team has in-depth knowledge of various building regulations, including Part L1A (New Build), Part L1B (Extension or Conversion), Part L2, Part F, Part O, and Part S. This expertise ensures that your project is fully compliant with the latest standards and regulations.

SAP Calculations

The Standard Assessment Procedure (SAP) is a government-approved system for measuring the energy efficiency and environmental impact of residential buildings. SAP calculations are critical for generating EPCs, which provide detailed information about energy consumption, carbon emissions, and overall efficiency. These calculations are required for new builds, conversions, and certain extensions to comply with Part L of the Building Regulations. Specifically, SAP assessments focus on two primary benchmarks: Dwelling Emission Rate (DER) and Dwelling Fabric Energy Efficiency (DFEE). Both must meet or fall below the Target Emission Rate (TER) and Target Fabric Energy Efficiency (TFEE) to pass.

SAP ratings range from 1 to over 100, with higher scores indicating better energy efficiency. Properties scoring above 100 are considered energy self-sustaining, making them both environmentally friendly and cost-efficient. These ratings help developers and homeowners pinpoint areas for improvement, reduce environmental impact, and lower energy costs. Therefore, conducting assessments early is key to ensuring compliance and guiding sustainable building practices.

SBEM Calculations

SBEM (Simplified Building Energy Model) calculations are essential for evaluating the energy performance of both new and existing commercial buildings. These calculations ensure compliance with Part L2 of the UK Building Regulations. By estimating the energy required for heating, lighting, and ventilation, SBEM calculations enable developers to make informed decisions that improve energy efficiency and reduce carbon emissions. Notably, SBEM assessments are conducted in two stages: the design stage, which is necessary for planning approval, and the “as-built” stage, which is required for final certification and Energy Performance Certificate (EPC).

With extensive experience in providing SBEM calculations for a wide range of commercial projects—from small retail units to large developments—we work closely with clients to balance energy-saving opportunities with regulatory compliance. As a result, our approach ensures that each project meets energy standards while optimizing building performance.

Water Calculations

Water calculations are crucial for determining a building’s water usage and ensuring compliance with Part G of the Building Regulations. These calculations help design systems that reduce water consumption and promote sustainability, particularly in new residential buildings. Specifically, a water efficiency calculation, required by Part G, ensures that water use does not exceed 125 liters per person per day. In certain areas, such as those following the London Plan, stricter targets of 110 liters per person per day may apply. These calculations assess the efficiency of fixtures and systems, including toilets, showers, taps, and appliances, by considering flow rates, fixture capacity, and water-saving technologies.

By conducting water calculations early in the project, builders can optimize water usage, reduce costs, and ensure compliance with regulatory standards. This proactive approach not only supports sustainability but also helps minimize environmental impact, contributing to a more water-efficient future.

U-Value Calculations

U-Value calculations measure heat loss through a building’s fabric, such as walls, roofs, floors, windows, and doors. A lower U-Value indicates better insulation, which reduces heat transfer and improves energy efficiency. Consequently, this helps lower heating and cooling costs while maintaining a stable indoor temperature. U-Value calculations are essential for both new builds and retrofitting older buildings to meet energy efficiency standards and support the UK’s net-zero carbon target by 2050. By addressing U-Values early in the design phase, you can prevent costly retrofitting and maximize long-term energy savings.
