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

So, Just What Are Sap Calculations?

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

How Much Do Sap Calculations Cost

If there are a number of properties with similar types of constructions, then special discounts may apply. But typically for a single property the charge would be in the area of £120 – £300. By supplying the plans, it will be possible to get a fixed quote.

What Is The Difference Between Sap and EPC

Before we get to the differences, this 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 calculations of pre defined data set of a buildings design that’s put together to demonstrate the energy performance of a building. EPC is short for Energy Performance Certificate and it’s a summary report of the SAP calculations in an straightforward document, which can also be used to sell or rent a property.

There are actually two kinds of EPCs. The first is a SAP EPC which is created from building plans where all of the components of the building are known. This would normally be needed by building control to show that the property satisfies specified targets required by the building regulations. Building control would must also see the SAP calculations which illustrates in detail whether all the components going into the property conform to the building regulations.

The second variety of EPC is the typical one that will be needed for anybody who is marketing, or renting out a property. This kind of EPC uses what’s called rdSAP, which is short for Reduced Data Standard Assessment Procedure, and is used where specified thermal values of, for instance, the walls, roof, floors, etc, are not precisely known on an established property. In this instance assumed thermal values are used according to the age of the property. This sort of EPC would be no good to show compliance with any building regulations. Sometimes building control would simply ask you for the EPC, however 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).

Still perplexed, after that call us for additional information.

What Are As Built SAP Calculations

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

 

 

Can I Do The Sap Calculation Myself

No, this is not some thing you could do yourself. The calculations need to be carried out by an On Construction Domestic Energy Assessor or OCDEA, by using approved Government software programs. The Assessor has to be approved under one of the certification schemes and is also regularly audited to keep up their accreditation.

What Information is Required 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

All new property require 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 fashionable to get large bi-folding doors, sky lights and large amounts of glazing on new extensions. But with the latest building regulations the quantity of glazing must be a maximum of 25percent of the floor area of the new extension. Therefore over compensations on the thermal elements in other areas within the property will need to be made to demonstrate that the CO2 emissions coming from the current house and the proposed extension is not any 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 need SAP calculations to find solutions and illustrate compliance.

 

Sap Calculations For Conversions

When you are 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.}

 

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 checklist is not exhaustive. Phone us, if you are uncertain if you need them.

 

So, Just What Are Sap Calculations?

For anyone who is reading this article, you’ve more than likely been asked by somebody, typically your building control officer, to provide 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 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 it is the UK government’s method of determining the energy performance of properties. Sap calculations are needed to illustrate that a building complies with specified energy targets laid down in the building regs.

As a short summary, that’s essentially it.

Some of the reasons you will be asked for sap calculations
1. For all newly built properties
2. For a dwelling change of use, for example changing a commercial building to flats
3. For extensions that have more than 25% glazing

The two 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 roof, floors, walls and windows comply with certain thermal targets.

A good set of building drawings will need to be provided to the Assessor, as all the calculations are done from the building drawings . Your Assessor will advise you of precisely what is needed. When the calculations are completed, an Energy Performance Certificate or EPC can also be created.

If the sap calculations show that your property isn’t compliant, then Assessor will give you advice on improvements which can be made to make it so. It could be costly if you realise at a late stage in the construction that your building isn’t compliant. So it is advisable to liaise with your Assessor as early on during the project as possible, ideally before any building commences.
