Energy regulation in the UK is entering a period of transition for new homes. The long-established Standard Assessment Procedure (SAP), which assesses residential properties and produces Energy Performance Certificates (EPCs), is planned to be phased out and replaced by the Home Energy Model (HEM), a new methodology that the government intends to provide a more…
Windows and doors do far more than bring light and access to your home, they play a major role in how well it retains heat. Their performance is measured by one key metric: the U-Value. A U-Value shows the rate of heat transfer through a material, measured per square metre for every degree of temperature…
Energy efficiency is at the heart of modern building design. In the UK, every new build, conversion, or extension must meet strict standards under the Building Regulations, and two of the most important metrics in achieving compliance are SAP Calculations and U-Values. While both are used to assess a building’s thermal performance, they measure different…
For over a decade, SAP (Standard Assessment Procedure) 2012 was the standard framework for assessing the energy performance of dwellings across the UK. Every developer, architect, and builder relied on it when working to comply with Building Regulations Part L and to secure a valid Energy Performance Certificate (EPC). The energy landscape, however, underwent significant…
When undertaking a new build construction of properties or an extension on your home, there are a lot of things you need to consider to ensure your building is compliant with all current Building Regulations. One of the most important considerations for your property development is a SAP calculation (Standard Assessment Procedure). If you’re not…
SAP Calculations for New Builds are a mandatory energy assessment used across the UK to measure how energy-efficient a newly constructed property will be. SAP stands for Standard Assessment Procedure and is the government-approved methodology for evaluating a building’s carbon emissions, predicted running costs and overall energy efficiency rating. For developers, architects, and builders, SAP…
