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

• have to demonstrate how they are keeping up to
  date with the latest changes to the regulations
  so you will be in safe hands.
• Get your SAP calculations done at the design
  stage
• SAP Calculations are done in two stages, design
  stage and as built. 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 its 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 cant ignore it,
  so it is best to try to get your assessment done
  early.
