Change the way you calculate PSI values. autoPSI is quick, precise and user-friendly software for thermal modelling construction junctions in minutes.
Junctions modelled in minutes
Not the hours or days that general-purpose thermal modelling software takes.
Precise, not default
Calculated PSI values instead of the conservative defaults that push up build cost.
Built for technical teams
Housebuilders, architects and SAP assessors. No thermal modelling background required.
Assessment-ready output
Results in the form you need to pass regulatory assessment.
Change the way you calculate PSI values
We understand there are many considerations when you are designing your building to meet the requirements of the Building Regulations.
Traditional thermal modelling software can be complex, time-consuming and expensive; while the allowable defaults 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.
We developed autoPSI as a quick, precise and user-friendly way of thermal modelling your construction junctions in minutes, saving time for you and the team.
