About this Gig

If you're designing a heating system, you need an accurate heat loss calculation before you can size anything correctly get it wrong and you end up with an oversized boiler, undersized radiators, or a system that fails inspection.


I'm a building engineer (civil, structural, and architectural background) who calculates heat loss and heating loads to EN 12831, ASHRAE, or CIBSE standards, depending on your region.


What I calculate:

  • Room-by-room fabric (transmission) heat loss
  • Ventilation and air infiltration heat loss
  • U-values for walls, roofs, floors, windows, and doors
  • Design temperatures based on your building's location
  • Total building heat loss (kW/BTU)
  • Radiator, underfloor heating, or boiler sizing recommendations


What you'll receive:

  • Full calculation report (PDF)
  • Editable calculation workbook (Excel)
  • Room-by-room breakdown table
  • Heating system sizing recommendations
  • Revision support based on your feedback


Whether it's one room or a full building, I'll make sure your heating system is sized right the first time. Message me before ordering.
