SAP Energy Software 

Our investment in our SAP energy software goes beyond incorporating new regulations and conventions in a smooth and timely manner. New Build Dwellings are probably the most complex when it comes to energy assessment procedures, particularly when you are working on large housing developments.

We believe that quality SAP EPC software should constantly challenge and resolve that complexity to help you achieve the highest assessment standards whilst freeing up your time to focus on income generating activity. 


About Standard Assessment Procedure (SAP)

SAP is the government's national calculation methodology for the energy efficiency assessment of newly constructed (new build) dwellings. Elmhurst Energy has developed Design SAP 2012, a further evolution of our Design SAP 2009 and 2005 software products, which are used for building energy calculations throughout the On Construction industry. Our SAP EPC Software is used by many leading industry professionals including the likes of consultants, manufacturers, house builders, Building Control/Standards Bodies, Universities/Colleges etc.

About Design SAP

All versions of Elmhurst's Design SAP Software are fully BRE tested and Government approved; they calculate the necessary building regulations/standards for England (Part L), Wales (Part L) and Scotland (Section 6).

Design SAP 2012 calculates the SAP rating, the environmental impact rating (EIR), the dwelling emission rate (DER), the target emission rate (TER), the dwelling fabric energy efficiency (DFEE) and the target fabric energy efficiency (TFEE) as well as incorporating Elmhurst's renowned U-Value calculator.

Elmhurst's Design SAP Energy Software differs to other SAP EPC software as it can be used by either accredited On Construction energy assessors (OCDEAs) who can produce new build PEAs and EPCs as well as Building Regulation/Standards calculations, or by individuals that aren't accredited, to produce basic Building Regulation/Standards calculations.
