Data and metering
What does gas conversion factor mean?
The gas conversion factor is a dimensionless factor used to convert measured gas volume from operating conditions to specified standard conditions. It accounts particularly for the pressure and temperature conditions relevant to conversion.
The data basis, contract scope and distinction from related terms are essential for applying this to a portfolio. Gross and net calorific values are not identical. Terms, units and reference conditions cannot be freely interchanged when checking bills.

PROPERTY PRACTICE
What does this mean for your portfolio?
Take the conversion factor from the relevant billing documents. A generic value for every building is not a reliable basis. Together with gross calorific value, it connects volume measurement with billed energy.
An example.
Our own example: 1,000 m³ of operating volume with a conversion factor of 0.95 gives a standard volume of 950 m³. Only further multiplication by gross calorific value produces energy in kWh.
Simplified example to explain the term. Actual metering data, the supply concept and agreed terms are decisive.
WHAT MATTERS
Three questions for your portfolio.
Are operating and standard volumes distinguished?
Is the subsequent conversion to kWh traceable?
Make the distinction clear
Distinction from gross calorific value: gross and net calorific values are not identical. Terms, units and reference conditions cannot be freely interchanged when checking bills.
