Want an answer to a question you have about SAP calculations in Mile End? Here are the 10 most frequent questions.

What Exactly Are Sap Calculations?

This is quite possibly the most frequent question asked. Check out Andrea’s video explanation above, or read the full explanation here on the right.

Sap Calculations, How Much Are They

If there are multiple properties with similar forms of constructions, then discounts may apply. For individual properties then you would be looking in the region of £120 – £300 dependant upon the complexity of the construction and the dimensions. By supplying the plans, you will be able to get yourself a fixed quote.

What Is The Difference Between Sap and EPC

Before we get to the differences, here is what you will require depending on your project.

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 building. An EPC or Energy Performance Certificate is a overview report derived from the Sap calculations which produces a SAP score from 0 to 100. This score is shown on the EPC as A the highest to G the lowest. It will also list recommendations that would improve the rating of the property.

There are really 2 kinds of EPCs. The first is a SAP EPC that is created from building plans where all the components of the building are known. This would normally be needed by building control to show that a dwelling meets specific targets essential to the building regulations. Building control would also need to see the SAP calculations which illustrates in detail whether the many components going into your property conform to the building regulations.

The second form of EPC is the regular one that would be necessary if you are marketing, or renting out a property. This particular EPC uses what’s called rdSAP, which is short for Reduced Data Standard Assessment Procedure, and is used where specific thermal values of, for example, the walls, roof, floors, etc, usually are not precisely known on an existing property. In this situation assumed thermal values are used according to the age of your property. This kind of EPC will be no good to show 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).

If you are still confused, then phone us for additional assistance.

What Are As Built SAP Calculations

These are the final set of SAP calculations produced once the dwelling has actually been completed to hopefully demonstrate that it is compliant with Part L1A of the building regulations. Prior to the building starting, it ought to have had a set of “Design Sap” calculations to show that the planned dwelling, in theory at least, will be compliant with Part L1A.

 

 

Can I Do The Sap Calculation Myself

Unfortunately this is not some thing you can do yourself. The calculations must be carried out by an On Construction Domestic Energy Assessor or OCDEA, by using approved Government computer software. The Assessor must be certified under one of the certification schemes and is also regularly audited to keep their qualification.

What Info 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 dwelling need Sap calculations to prove compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regulations.

 

Sap Calculations For Extensions

It’s now trendy to get large bi-folding doors, sky lights and large amounts of glazing on new extensions. However under the present building regulations the amount of glazing must be a maximum of 25percent of the floor area of the new extension. So over compensations on the thermal elements in other places within the property will have to be made to demonstrate that the CO2 emissions coming from the existing house along with the planned extension is no worse than the existing house and an extension whose glazing is within the allowed amount judged against Part L1B of the building regulations.

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

 

Sap Calculations For Conversions

When you are changing the use of a dwelling, 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. Call us, if you are uncertain if you require them.

 

What Exactly Are Sap Calculations?

For anyone who is reading this, you’ve more than likely recently been requested by someone, usually your building control official, to supply sap calculations for your building project. But you probably haven’t been told what sap calculation actually are and why you need them.

You can click on the video clip on this page, where Andreas will shed some light on this, or read on.

SAP is short for Standard Assessment Procedure and its the united kingdom government’s method of calculating the energy performance of buildings. These calculations are required to show your building conforms with specific energy targets laid down in the building regulations.

As a brief overview, that’s basically it.

Sap calculations tend to be required for three main reasons

1. For all newly built properties
2. For a dwelling change of use, for example changing a commercial building to residential flats.
3. For overglazed extensions

The 2 main areas that the sap calculations will look at is that the carbon emissions from the property are within set tolerances and that particular components of the property, for example the windows, floors, walls and roof comply with specified thermal energy targets.

The calculations will be done by a qualified and accredited On Construction Domestic Energy Assessor. There is not any need to visit the property because all the calculations are carried out from the building plans . An EPC or Energy Performance Certificate is usually produced once the calculations are completed.

If your sap calculations show that your property isn’t compliant, then Assessor will give you suggestions about improvements which can be made to make it so. It might be expensive if you realise at a late stage in the construction that the building isn’t compliant. So it’s advisable to liaise with the Assessor as early on during the project as possible.
