What does SAP mean?

SAP stands for Standard Assessment Procedure and is the UK government’s way of determining the energy efficiency of buildings. Sap calculations are needed to demonstrate that your building complies with specific energy targets laid down within the building regs.

That’s more or less it in a simple summary.

 

When Are SAP Calculations Needed?

Here are most of the reasons you may well be asked for sap calculations

1. For extensions that have more than the permitted amount of glazing
2. For all new dwellings
3. For a dwelling that’s changed its use, such as altering a commercial building to residential flats.

The 2 main areas that the sap calculations will look at is that the carbon emissions from your dwelling are within set tolerances and that certain components of the property, such as the roof, windows ,floor and walls comply with certain thermal energy targets.

A good set of building plans will need to be given to the Assessor, since all the calculations are done from the building plans ,so there is no need to visit the property. Your Assessor will advise you of precisely what is needed. When the calculations are finished, an Energy Performance Certificate or EPC can also be created.

Your Assessor can give you further guidance if the calculation show your building isn’t compliant, as well as explain to you which will be the most effective improvements to make. It is crucial that you liaise with the Assessor as early on in your project as possible because once the building is finished any non-compliances could be quite costly to rectify.

Questions Regarding Golders Green Sap Calculations, see if we have an answer here.

What Are Sap Calculations?

This is probably the most common query asked. Have a look at Andrea’s video explanation above, or read the full explanation here on the right.

Sap Calculations, How Much Are They

We will be pleased to provide discount rates, especially for multiple dwellings that are of the same or very similar construction. For single properties then you would be looking in the region of £120 – £300 dependant upon the difficulty of the design along with the dimensions. By supplying the plans, you will be able to get a fixed price quote.

What’s The Difference Between Sap and EPC

Before we explain the difference, here is what you will require depending on your job.

For a new build property you’ll need – SAP calculations and an EPC.

For dwelling change of use or conversion you’ll need – Sap Calculations and an EPC.

For overglazing on an existing dwelling you’ll – Sap calculations only.

SAP or Standard Assessment Procedure are the calculations of pre defined data set of a properties design that’s put together to show the energy performance of a property. An EPC or Energy Performance Certificate is a summary report derived from the Sap calculations which produces a SAP score from 0 to 100. This score is expressed on the EPC as A the highest to G the lowest. It will also list suggestions which would improve the rating of the dwelling.

There are actually two types of EPCs. First is a SAP EPC that is produced from building plans where all the components of the building are known. This will normally be needed by building control to demonstrate that a property satisfies specific targets essential to the building regulations. Building control would also need to see the SAP calculations which illustrates in greater detail whether all the components going into the property comply with the building regulations.

The 2nd sort of EPC is the regular one that will be required for anybody who is marketing, or renting a property. This kind of EPC uses what’s called rdSAP, which means Reduced Data Standard Assessment Procedure, and is used where particular thermal values of, for example, the walls, roof, floors, etc, usually are not precisely known on an established property. In this case assumed thermal values are used based on the age of the property. This sort of EPC would be no use to demonstrate compliance with any building regulations. Sometimes building control would simply ask you to get an EPC, but what they would really require are the Sap calculations (which is the information behind the EPC) and the SAP EPC (which is a summary report from the Sap calculations).

Still confused, then simply contact us for additional assistance.

What Are As Built SAP Calculations

These are the finished set of SAP calculations generated once the building has actually been completed to confirm that it is compliant with Part L1A of the building regulations. Ahead of the building starting, it ought to have had some “Design Sap” calculations to demonstrate that the planned dwelling, in theory at least, would be compliant with Part L1A.

 

 

How To Do Sap Calculations

Unfortunately this is not something that can be done by yourself. The calculations have to be done by an On Construction Domestic Energy Assessor or OCDEA, working with approved Government computer software. The Assessor must be certified under one of several accreditation schemes and is also regularly audited to maintain their qualification.

What Information is Needed For Sap Calculations

Your Assessor would advise you of exactly what is needed. Typically you would need the following:

  • Floor Plans to include sections and elevations
  • Orientation of the property
  • Construction specification of walls, roof and floors
  • Specification for all doors and windows
  • Primary and secondary heating
  • Provision for providing  hot water
  • Any renewable technology (if any)

 

Sap Calculations For New Build

Every new property need to have Sap calculations to demonstrate compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regs.

 

Sap Calculations For Extensions

It’s now quite modern to have large bi-folding doors, sky lights and large amounts of glazing on new extensions. But with the latest building regulations the quantity of glazing can be no more than 25% of the floor area of the new extension. Therefore over compensations in the thermal elements in other parts within the property will have to be made to show the CO2 emissions from the existing house along with the planned extension is no worse than the existing house and an extension whose glazing is within the permitted amount judged against Part L1B of the building regulations.

You will need SAP calculations to find solutions and demonstrate compliance.

 

Sap Calculations For Conversions

For anybody who is changing the use of a building, you will require Sap calculations. {The new dwelling will have to comply with Part L1B of the building regulations.}

 

Do I Need to have Sap Calculations

You will need Sap calculations for any of the following: 

  • Building a new property
  • Changing the use of an existing property (e.g, a barn conversion, commercial building to residential)
  • Extensions with more than 25% glazing
  • Opening up the main house to an existing conservatory
  • Extension where the extension is more than 50% of the original property wall area
  • Garage conversions
  • If requested by building control

This is not an exhaustive checklist. If you’re not certain whether you will need them, then give us a call.
