What is the difference between SAP and EPC?
If you work in the construction business, you’re certainly aware with the phrases Standard Energy Procedure (SAP) and Energy Performance Certificate (EPC). However, what are the distinctions between the two, and how do they relate to one another?
What is the distinction between SAP and EPC? Your SAP calculation is the mechanism underlying the all-important EPC, and it is simply a comprehensive series of calculations to measure a building’s overall performance. The EPC is evidence of such computations.
The Standard Energy Process is a methodology developed by the government to demonstrate that a structure meets the energy and carbon standards outlined in current construction rules. It is a measurement of a home’s energy and environmental performance. After a SAP computation is agreed upon, it will be utilised to create the Energy Performance Certificate.
Why do I need SAP Calculations?
If you want to pass construction requirements, you must offer a SAP calculation for your home. Part L of the building requirements require you to demonstrate that your house fulfils both the carbon emissions and fabric performance standards.
It also verifies your compliance with carbon and energy savings planning standards.
You may next create your Expected Energy Assessment (PEA) and your EPC: without these, your new house cannot be sold or inhabited.
What is a good SAP score?
Your SAP score is your method of demonstrating your home’s energy performance, and it will be used to compare it to other houses.
The resulting value will be between between 1 and 100+. The better your SAP rating, the lower your energy expenses and, as a result, your CO2 emissions.
A score of 100 reflects no energy cost; anything higher indicates that you are exporting energy.
So, to summarise? A high SAP score is considered favourable.
How is my SAP score calculated?
Your SAP score is established by examining the numerous ways your building utilises (and wastes!) energy.
It will take into account:
- Building materials
- Heating and cooling systems (and how efficient they are)
- Any solar benefits discovered through property openings
- The thermal insulation level
- Renewable energy technologies of any kind
- The energy source you utilise for water and space heating, lighting, and ventilation.
- Leakage of air
Each region will be assigned a score, which will assist define your total SAP calculation.
Why do I need an EPC?
When a building is sold, rented, or built, a valid EPC is required by law. The certificate serves as confirmation of your property’s energy efficiency as well as any possible savings on energy expenditures.
You must obtain an EPC in order to put your house on the market.
What is a good EPC rating?
If your EPC rating is A, you may feel assured that you have received the highest possible rating.
Existing tenancies cannot be extended or new tenancies granted if the EPC rating is less than E, and the bands range from A to G. This requirement will also apply to landlords with existing residences with an EPC rating less than E as of April 2023.
How is my EPC rating calculated?
Your EPC rating is calculated using your SAP score. And this is where your EPC SAP points come into play.
The EPC SAP points ratings are as follows:
- A – 92-100 SAP points
- B – 81-91 SAP points.
- C – 69-80 SAP points.
- D – 55-68 SAP points.
- E – 39-54 SAP points.
- F – 21-38 SAP points.
- G- 1-20 SAP points.
A few simple ways to improve your EPC rating include:
- Double glazing
- Loft insulation.
- Wall insulation
- Replace your boiler
- An efficient secondary heating source
