PSI Value Calculator
We understand there are many considerations when you are designing your building to meet the requirement for Building Regulations.
Traditional thermal modelling software can be complex, time-consuming and expensive; while the defaults allowable can often have a detrimental effect on the overall cost of construction required to meet regulations.
This is often a challenge for technical teams, housebuilders, architects and SAP assessors. But with AutoPSI as your dedicated PSI value software, you can do PSI value calculations with speed and pass each regulatory assessment with ease.

Why is PSI Value Calculation Necessary for Construction Design?
A PSI value calculation is important because it tracks heat loss in construction junctions, and our PSI value calculator makes this easier with templates and a user-friendly interface. But what makes building thermal modelling software such a significant tool within the construction design industry?
PSI values are required by SAP/EPC building regulations to ensure that you comply with energy performance standards. They require a thermal bridging component, whether you include a separate PSI value or not. When using an assumed PSI value, you’re likely not going to pass.
A reliable PSI value calculation has many benefits:
- Stronger thermal bridging component: A PSI value (linear thermal transmittance), allows you to redesign the two thermal elements of a thermal bridge or junction to avoid greater heat loss.
- Sustainability: With accurate PSI values, you can design energy-saving spaces and remove unnecessary parts of a new build design, which can also save money further down the line.
- Reduce condensation and mould risks: A thermal bridge can cause harmful condensation and mould to spread. PSI value calculations will inform you of risks in advance when doing renovations.

How it Works
From U-values to non-repeating thermal bridges, PSI values play a big role in building design. With AutoPSI, you don’t need to worry about how to calculate a PSI value, because the values you need are just a few clicks away.
- Choose your junctions: Start by selecting from a set of SAP required junctions (windows, doors, gables, etc.), including options for timber, masonry and steel frames.
- Amend your values: Amend the K-values, thickness and other dimensions of your bridges and layers.
- Control your junctions: At this point in the calculation, you can delete, move and amend any thermal bridge or layer you need to, as per your own unique requirements.
- Change materials or add more layers: Utilise the user-friendly drop-down menu to change your materials or add more layers before initiating the PSI calculations.
- Calculate your PSI value at the click of a button: Within minutes, you’ll have your unbridged U-values, Q, F-values, and PSI values from our efficient PSI calculator, all available in a downloadable PDF report.
