Post-model worksheetHeating + cooling

Energy-Model Result
Summary Worksheet

Normalize heating and cooling energy needs from one completed building model and compare either result with optional, separately verified maximum criteria.

Who it's for: energy consultants and architects checking a completed energy model at design development against a verified project criterion.

Completed-model results
normalize and compare; no simulation

How to use this calculator

1
Complete one declared model
Use a method appropriate to the project, adoption, rating scheme, and intended decision.
2
Enter compatible results
Heating, cooling, and reference area must share the same model boundary and definitions.
3
Optionally enter verified criteria
Do not assume heating and cooling use the same limit or that a target transfers between schemes.
4
Read the arithmetic summary
The worksheet returns normalized results and optional comparisons; it does not validate or certify the model.

The formula

Heating intensity = annual heating need ÷ reference area.
Cooling intensity = annual cooling need ÷ reference area.
Combined arithmetic intensity = (heating + cooling) ÷ reference area. This is not whole-building delivered or primary energy.

Worked example

Example
For 6,000 kWh/yr heating, 4,000 kWh/yr cooling, and 500 m², the entered results normalize to 12, 8, and a combined arithmetic 20 kWh/m²·yr.

When this estimate will be off

  • Does not calculate energy needs, temperatures, loads, humidity, climate response, solar gains, internal gains, schedules, zoning, or system energy.
  • The arithmetic sum is not EUI for all fuels/end uses and is not primary, source, delivered, or renewable primary energy.
  • Does not select a code, rating, Passive House, PHIUS, or other criterion and does not establish certification.
  • Heating and cooling results from different models or floor-area definitions must not be combined.

Frequently asked questions

A common mistake: Does not calculate energy needs, temperatures, loads, humidity, climate response, solar gains, internal gains, schedules, zoning, or system energy.

No. It is only the arithmetic sum of the two entered energy-need quantities divided by their matching area.

The applicable limits depend on the selected scheme, climate, use, project path, and calculation boundary. This page does not invent them.

Only if a qualified reviewer confirms compatible definitions, boundary, area, period, and units. Otherwise the combined result is not meaningful.
