WORKFLOW GUIDE
Save and resume a project
Calculators remain available without an account. Sign in only when you want to save a project deliberately.
How it works
Run the calculation normally, select Save project, give it a clear title and retrieve it later from My account.
Project and PDF
A saved project keeps editable inputs. The PDF is the readable preliminary report to archive or share.
Good project records
Use a title that identifies the system and revision without exposing unnecessary personal data. When you reopen a project, check prices, climate data, equipment information and design conditions before generating a new result. Saved values may become outdated as the project changes. Keep the PDF issue date with other project records and create a new export after any material input change.
