PSI Values Checklist
This checklist has been carefully crafted to obtain the necessary information for performing your required services. Failure to supply this information to your energy assessor may result in time delays. Please take the time to read each required element and watch any helpful videos, along with using any download links to assist in your project. As always, we are here to Deliver Beyond Compliance.
1. Junction list
The SAP assessor will advise which junctions are required for the calculation. If you’re unsure, please speak with them directly. We’ll be happy to assist you further once the list is confirmed.
2. Accurate drawings
We require accurate drawings for each junction that needs assessing. These are essential for carrying out reliable PSI Value calculations.
3. Drawings — floor plans, sections, and elevations
Position and layout drawings are helpful to provide context, but they are not essential. If available, please include them with your submission.
