Audited planning profile
This couple ten-year profile applies a 2× editable baseline across 120 model periods to the home office buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Agree on shared inputs and ownership before comparing the two-person result. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
