As Built SAP Calculations are generated by the SAP calculations for building control. They assign an energy rating to the structure in issue. If the SAP calculations for a new building show a pass, the project is in compliance with Building Regulations Part L. Different requirements apply when the building control officer requests as built SAP Calculations and EPC for additions, changes of use, and refurbishments. Once the building is finished and all work has been accomplished in accordance with the SAP Calculation standards, an on-site Energy Performance Certificate (EPC) is generated using As Built SAP calculations.

What exactly are SAP Calculations?

SAP is the government’s ‘Standard Assessment Procedure’ for Dwelling Energy Rating. The government has embraced SAP 2012 (and upgrades) as part of the UK standard methodology for calculating the energy performance of buildings. It is used to demonstrate compliance with residential building rules – Part L (England and Wales), Section 6 (Scotland), and Part F (Northern Ireland) – as well as to offer energy ratings for houses.

It is the only official, government-approved technique for determining a new home’s energy rating. SAP assessors are required to be accredited and registered with a certifying organisation.

A SAP Rating is a method of evaluating the energy performance of different dwellings; it yields a number between 1 and 100+. (100 representing zero energy cost and anything over means you are exporting energy). The greater the SAP grade, the lower the fuel expenses and related carbon dioxide emissions.

The SAP Calculations calculate the energy cost of a home depending on its construction, heating system, indoor lighting, and any renewable technology installed. It excludes energy consumed for cooking and appliances.

Why Do We Require a SAP?

SAP Reports employ the Standard Assessment Procedure to deliver building rules Part L compliance material. The Standard Assessment Procedure is the government’s approach system for assessing residential buildings’ energy efficiency and carbon emission rates.

When Do We Require a SAP?

Building rules Part L compliance requires SAP calculations for all new construction projects, conversions, and additions when the glass area exceeds 25% of the floor area. SAP calculations are performed in both residential and commercial properties at the beginning, during, and at the end of the design process. This allows you to be informed of any changes that may influence the project’s energy rating throughout construction.

How Are SAP Ratings Calculated?

The SAP rating is determined by the energy expenditures associated with space heating, water heating, ventilation, and lighting.

The information gathered from drawings, building notes, and spec sheets is entered into certified software, and a draught report is generated. If the project fails, EAL will provide suggestions on how to improve your rating, such as lowering u values, increasing the number of energy-saving lighting in the home, and adding extra insulation.

SAP Calculations will be required by your architect, builder, or developer, or if you are a homeowner building an expansion.

It is the obligation of the owner to produce an EPC when the house is built or converted; any major change in usage to the heating, hot water provision, or air conditioning/ventilation services.

If you are selling a property before it has been built, you must offer energy efficiency information in a Predicted Energy Assessment (PEA). This is an anticipated SAP and Environmental Impact rating based on SAP Calculations, and it is performed during the design phase to verify that the building meets the needed energy savings objectives.

If you need assistance with your SAP calculations or want to learn more about the process and how much SAP calculations cost, please contact MyConstructor, where our team of expert assessors would be pleased to help.

Our services include counselling customers on how to effectively comply with legislation. We aim to provide advice on available cost and energy-saving measures. Our SAP assessors will also communicate with Building Control Officers on your behalf.

What Should I Bring to a SAP Meeting?

Floor plans, sections, and elevations for existing home and addition Orientation, such as:

·         A site plan Construction specification for existing housing and expansion walls, roofs, and floors (this should include u-values where known) U-values

·         All windows must meet certain requirements.

·         Heating systems, both primary and secondary

·         Renewable energy technologies (if applicable)

When Should a SAP Calculation Be Conducted?

Before beginning construction, you should perform SAP calculations. This is done so that, throughout the design stage, you may be certain that the plans and specifications will pass. In the event of L1A SAP calculations, a second report will be required after the building is completed.

How Long Will It Take To Perform The SAP Calculation?

This is largely dependent on the building project’s timing. In general, UKBC strives to finish all reports within 5–10 working days of receiving a request.

What Happens If My Building Fails?

It is illegal to rent or sell a home that does not have an EPC. As a result, it is critical that your building pass its SAP. It is critical to establish your SAP calculations before building work begins, so that if the building fails to fulfil building regulations, our SAP assessors can advise you on how to improve. This gets more difficult and costly later in the project as the scope of adjustments available narrows. UKBC intends to offer complete assistance and guidance throughout the SAP process. Whereas many firms will merely perform the calculations, UKBC offers a consultation service to ensure that our clients receive the knowledge and guidance they need to pass the SAP.

How Do SAP Calculations Get Done?

The customer should offer as much information as possible in order for our staff to do computations.

This includes, but is not limited to, the following:

·         Floorplans

·         Elevations

·         Sections

·         Site Map

·         Insulation thickness/type

·         Openings’ U-value

·         Heating system specifications

·         production of hot water

·         Low-energy lighting percentage

·         Ventilation system specifications

·         Renewable energy technologies

·         Construction details that are approved

Your SAP Calculations will differ depending on whether your project is a new construction, an expansion, or a conversion. In any case, the computations are broken down into two reports: L1A and L1B SAP.
