The calculation of an EPC rating is based on a number of factors that determine the energy efficiency of a property.
These factors include the construction of the property, the heating system, insulation, and the type of windows and doors.
The construction of the building, the materials used in the construction of the property, as well as the design and layout, can have a significant impact on its energy efficiency.
The heating system in a property is also a key factor in determining its energy efficiency.
Insulation is another important factor in calculating an EPC rating.
The type of windows and doors in a property can also impact its energy efficiency.
In addition to these factors, the EPC rating also takes into account the energy usage of a property, such as the lighting, appliances, and hot water systems.
Overall, the EPC rating is calculated by assessing the energy efficiency of a property based on a number of factors, including the construction of the building, the heating system, insulation, and the type of windows and doors.

To calculate your Energy Performance Certificate, an energy assessor requires specific details about your property.
They will need to know the size of your property, including its dimensions.
Additionally, they will ask for information regarding your heating and hot water system, such as the type and efficiency.
The energy assessor will also inquire about the insulation and glazing in your property.
All this information will be entered into a software program which will then generate the EPC for your property.
Calculating an Energy Performance Certificate for a building involves using a method called the Standard Assessment Method (SAM).
SAM takes into account various factors, such as the quality of the building's construction, its size and shape, how it is used, the heating and hot water system, the type of windows and insulation installed, and other relevant details.
The EPC rating is then determined based on these factors, which gives an indication of how energy-efficient the building is.
The calculation of the EPC focuses on assessing the building's energy efficiency in terms of its structure.
This involves considering the materials used in its construction, their ability to conduct heat, and the level of insulation provided.

Data Recording Assessors must retain all data used for the EPC calculation and evidence that the data relates to the assessed property. This information is typically input into specialised software that calculates the EPC rating. The assessment is carried out by an accredited Domestic Energy Assessor using specialised software that follows the Standard Assessment Procedure (SAP) for residential properties or Simplified Building Energy Model (SBEM) for non-domestic buildings.

The EPC for a building is calculated using a Standard Assessment Method (SAM).
The EPC rating is then used to produce an energy efficiency indicator (EEI), which is a measure of how energy-efficient the building is.
The EPC calculation assesses the building’s ‘fabric energy efficiency’.
This calculation considers the thermal conductivity of materials used in the construction of the property and its insulation levels.
An energy assessor will need some information to calculate your EPC.
They will need the dimensions of your property, details about the heating and hot water system, and information about the insulation and glazing.
The energy assessor will input this information into a software program that will generate an EPC for your property.

To calculate an Energy Performance Certificate (EPC), you need a qualified assessor to carry out the assessment on your home. They will then look at many key areas of your home that will give them an idea of how much and how energy is used within the property. These areas can include the following:
Checking if the heating and water system is efficient, i.e. boiler make and model
Checking there is sufficient insulation in walls, floor and roof
What type of glazing are in the windows?
Even what light bulbs are fitted
How airtight the building is
As they progress through the property, they will allocate a score for each section, depending on how efficient and in what condition the areas are in. From this, they will calculate the energy efficiency score, which will provide the EPC rating for the property.
There are two types of EPC and two different ways of calculating one.
On Construction EPC: produced from a SAP Calculation for new build properties. This is calculated using the Standard Assessment Procedure method (SAP).
EPC: produced via a site survey by a domestic energy assessor on an existing property. This is calculated using the Reduced Data Standard Assessment Procedure method (RDSAP).
The SAP calculation is based on the volume of the property, all the main elements (floors, walls, roof, doors and windows), thermal bridging, insulation, heating and lighting.
A domestic energy assessor carries out RDSAP visiting the property and conducting a survey on the property, noting all the information required for the EPC.

Om je EPC (Energieprestatiecertificaat) te berekenen, zijn er verschillende stappen en overwegingen.
Allereerst worden professionele assessors ingeschakeld om de energieprestatie van een gebouw te beoordelen.
Ze onderzoeken factoren als het type gebouw, de leeftijd, de grootte, en de locatie.
Vervolgens wordt de energie-efficiëntie van het gebouw beoordeeld met behulp van de Standard Assessment Method (SAM), een methode die meerdere aspecten van het gebouw in overweging neemt.
Dit omvat de kwaliteit van de constructie, de grootte en vorm, het gebruik door de bewoners, en het verwarmingssysteem.
Ook de ramen en isolatie worden geëvalueerd om te zien hoe effectief ze warmte vasthouden.
Depunten worden toegekend op basis van de efficiëntie van onderdelen zoals isolatie en verwarming, en hoe hoger de score, hoe efficiënter het gebouw.
De EPC-score is gebaseerd op een kleurencodesysteem met zeven banden, waarbij A (donkergroen) de meest efficiënte is en G (rood) de minst efficiënte vertegenwoordigt.
Om je EPC te krijgen, moet je een gecertificeerde energie-assessor inhuren om je huis te beoordelen.
Deze beoordeling duurt ongeveer 45 minuten tot een uur.
Vervolgens kun je vragen om het Energieprestatiecertificaat per e-mail te ontvangen.

To estimate your EPC yourself, you need to consider the following factors:
If you want to estimate your EPC yourself, you need to consider the factors in the provided table.
The final score will give you an estimated EPC rating for your property.
The EPC calculator follows a specific formula.
The calculation includes: Heat loss through walls, floors, and roofs, Efficiency of heating systems and controls, Energy used for lighting and appliances, Renewable energy contributions.
The final score is converted into an EPC rating between A and G.

To calculate your EPC rating, the assessor will first calculate the property’s Standard Assessment Procedure (SAP) score and then use that to determine the EPC rating. The SAP score is calculated by looking at all the ways that your property uses and loses energy, including how energy efficient the heating system is, how well the property is insulated, what energy source is used, and whether the property has any renewable energy technologies installed. The results will then be used to calculate the property’s overall SAP score, which will usually be between 1 and 100, with a score of 100 meaning that there is no energy cost. The EPC rating is based on how much energy your property uses per square metre and how much energy it loses. The average EPC rating in the UK is D. An EPC rating is based on a rating or band, ranging from A to G, with A being the most energy efficient. Your home’s SAP score will be used to determine the EPC rating.
