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), Northern Ireland (Part F) 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 either by accredited On Construction energy assessors (OCDEAs) who can produce new build EPCs as well as Building Regulation/Standards calculations, or by trained individuals that aren't accredited, to produce solely the Building Regulation/Standards calculations.

Features and Benefits


New/Recently released features

We continue to develop new functionality and make improvements to our leading Design SAP software. This ensures that our software remains the first choice for SAP Calculations. 

BIM Functionality within Design SAP 

The exchange of data from multiple CAD software/energy modelling tools to Design SAP is an important step into Building Information Modelling (BIM), where users can take information from 3D Models and build an accurate energy profile through Elmhurst's Design SAP. 

Elmhurst Members now have access to a gbXML converter within the OCDEA Zone in Access Elmhurst. With this tool members can convert multiple gbXML files exported from leading CAD packages, such as AutoCAD, IES and SketchUp, at the click of a button to speed up, and reduce errors, in your SAP assessments. 
For more information on the gbXML scheme and to view a list of compatible software products, please click here.

Search for an Air Pressure Tester 

Elmhurst Energy Assessors can now search for a registered air tester nearby, when they require an air pressure test for their SAP Calculations.

Design SAP and Home Quality Mark (HQM)

The Home Quality Mark (HQM), which has been created by BRE as a replacement for the Code for Sustainable Homes, allows house builders to demonstrate the high quality of their homes and to differentiate them in the marketplace.

Elmhurst Energy are supporting this new national quality mark, by providing integration between the HQM scheme and our industry leading SAP EPC software; simplyfying and speeding up the time taken to produce Home Quality Mark Assessments.

Energy assessors can now use Elmhurst’s Design SAP software to export an output file which can be uploaded directly into BRE’s system. This means that SAP Data can be sent to and used by HQM assessors to develop an accurate quality rating for new build homes.
