How to achieve better SAP assessment results?

1. Title: How to achieve better SAP assessment results? Content: SAP assessment is a method to determine the energy and environmental efficiency of new buildings to ensure that the new developments are designed and constructed in accordance with the building regulations. This government approved method evaluates the energy ratings and CO2 emissions of residential properties. This method, also known as SAP calculations, SAP ratings or SAP certificates are used to give an estimation of energy performance (EPC) which is required when selling the property or completing a new build or conversion. And for getting a better SAP calculation result, certain points need to be considered, such as: •Use an accredited assessor Make sure you use an assessor who is a qualified OCDEA (On Construction Domestic Energy Assessor). These can be found using www.theepcregister.co.uk or will display their scheme details and membership number on their website. As a part of their ongoing continuing professional development, an accredited assessor will

Building Control require both parts of these to be completed. If the design stage is not completed, there is the risk that the project will not pass once you get to completion. Trying to retrofit insulation or add renewables at a late stage is more expensive and can delay your project so it’s always best to get the SAP Calculations done at the beginning of the projet. •Include methods that help lower the thermal mass Passing the SAP assessment becomes quite easy if you choose a low thermal mass such as a timber frame. Low thermal mass will mean less load on the heating system for heating the building and hence less consumption of energy. •Insulate walls Insulted party walls are among the top contributors for better SAP results. Not just the uninsulated party walls are a big ‘No’, but even partially insulated party walls are punishable. •Energy saving light bulbs Installing energy saving bulbs is like killing two birds with one stone. On one hand where you save big amounts on your energy bills, on the other you can make significant improvements on the SAP by using LEDs or fluorescent tubes. While these were just a few tips that help in achieving better SAP calculation results, there is no fixed formula for getting a SAP Pass. Furthermore, since SAP assessments are a legal requirement for all properties under Part L of the building regulations, you can’t ignore it, so it is best to try to get your assessment done early.
