Here we have provided the most typical queries asked about SAP Calculations in Manchester.

What Are Sap Calculations

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

How Much Do Sap Calculations Cost

This will vary considerably dependant upon the size and complication of the dwelling, but a typical price range would be between £120 – £300. There will probably be a further fee of approximately £50 if an EPC is needed at the end of the construction. Discounts would typically be available for multiple dwellings especially when they are of the same form of construction.

What Is The Difference Between Sap and EPC

Before we explain the difference, here is what you will need 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 computations of pre defined data set of a buildings design that’s created to demonstrate the energy performance of a property. An EPC or Energy Performance Certificate is a overview report produced by the Sap calculations which produces a SAP rating from 0 to 100. This rating is expressed on the EPC as A the highest to G the lowest. It will also list suggestions which would increase the rating of your dwelling.

There are actually two kinds of EPCs. First is a SAP EPC which is created from building plans when all the elements of the building are known. This would normally be required by building control to demonstrate that the property complies with certain targets essential to the building regulations. Building control would also need to see the SAP calculations which illustrates in detail whether all of the components going into your property conform to the building regulations.

The 2nd variety of EPC is the common one that will be required for anybody who is marketing, or renting out a property. This type of EPC uses what’s called rdSAP, which means Reduced Data Standard Assessment Procedure, and is used where specific thermal values of, for instance, 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 your property. This type of EPC would be no good to demonstrate compliance with any building regulations. Sometimes building control would simply ask you to get an EPC, but what they would really need to have are the Sap calculations (which is the data behind the EPC) and the SAP EPC (which is a summary report of the Sap calculations).

If you are still perplexed, then simply phone us for further information.

What Are As Built SAP Calculations

These will be the final set of SAP calculations produced once the building has been completed to hopefully demonstrate that it is compliant with Part L1A of the building regulations. Prior to the construction starting, it should have had a set of “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 some thing you can do yourself. Sap calculations need to be done by an On Construction Domestic Energy Assessor or OCDEA, by using approved Government software programs. The Assessor must be certified under one of the certification schemes and is regularly audited to keep up their certification.

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 Sap calculations to prove compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regs.

 

Sap Calculations For Extensions

It’s now fashionable to have large bi-folding doors, sky lights and large amounts of glazing on new extensions. However with the current building regulations the quantity of glazing must be no more than 25% of the floor area of the new extension. So over compensations on the thermal elements in other parts within the property will have to be made to demonstrate that the CO2 emissions coming from the current house along with the planned extension is no worse when compared to the existing house and an extension where the glazing is within the allowed amount judged against Part L1B of the building regulations.

You should have SAP calculations to find solutions and demonstrate compliance.

 

Sap Calculations For Conversions

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

 

Will I Need 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 need them.

 

What Are Sap Calculations

Have building control, or your architect asked that you get sap computations. Why do you need them and what exactly are sap calculations anyway? Then read on.

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

SAP stands for Standard Assessment Procedure and is the united kingdom government’s method of determining the energy performance of dwellings. The calculations are necessary to illustrate that your building conforms with certain energy targets set down in the building regs.

In a simple overview, that’s more or less it.

Sap calculations are generally needed for 3 main reasons

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

There are two main targets that the sap calculations are required to demonstrate. Firstly that the dwelling emission rate (DER) and the dwelling fabric energy efficiency (DFEE) comply with certain targets.

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

Your Assessor can give you additional advice if the calculation show that your building isn’t compliant, as well as explain to you which will be the most effective improvements to make. It might be expensive if you find out at a late stage in the construction that the building isn’t compliant. So it’s best to liaise with your Assessor as early on in the project as possible.
