SAP Calculations in London Aim for Lower Carbon Emissions

The SAP calculation has been around since the mid-nineties, providing a way of measuring the energy usage of new builds. Over the past twenty years global warming has placed an increased focus upon harmful carbon emissions which has had the knock-on effect of an increased stringency when it comes to SAP assessments. Our team of SAP assessors in London report that builders and developers are now being required to work to ever higher standards of energy efficiency in order to achieve compliance under building regulations Part L1 along with enhanced levels of performance required to satisfy the London Plan.


How Are SAP Calculations Arrived At?

SAP cals in LondonThe SAP calculation is a government approved system for assessing the amount of energy used by a new build. The calculation itself utilises a comparative methodology across different homes, whilst also taking into account the design and fabric of the build. The rating is represented as a figure between 1-100. If you were to hit the magical 100 it would mean that your regulated fuel costs and carbon emissions were zero; the aim of any new build, therefore, is to achieve a high SAP rating representing low carbon emissions and reduced fuel costs.


SAP Calculations in London – How to Achieve a Successful SAP Rating

Our team of dedicated SAP Assessors in London are asked this question again and again – and our answer is always the same: Design for low energy usage. SAP calculations require architects and planners to work with SAP assessors from the early stages of a build project in order to ensure that energy conservation has been a key determinant from the very start. Our highly qualified team of SAP assessors has worked across London onbrand new homes, renovations, extensions and refurbishments and in each case we focus on the areas where there is maximum potential for energy loss whilst ensuring the proposals are practicable and cost-effective:

  • Insulation – passive enhancement to the thermal envelope – walls, floors and ceilings – are vital.
  • Doors and Windows – high-performance products minimise energy loss in these key areas.
  • Responsive Controls – heating systems and controls are key for minimising heating & hot water emissions (& costs!).
  • Air Permeability Testing –aiming for a low target air permeability figure greatly assists the SAP performance.
  • Heat Loss – minimising incidental, uncontrolled losses such as thermal bridging at junctions is increasingly important for a dwelling’s performance.
