referansetemperaturen

Referansetemperaturen is a defined temperature used as a reference point in building physics, energy calculations and regulatory reporting. It acts as a baseline against which actual indoor temperatures, energy consumption and thermal performance are assessed. The concept is common in European energy performance standards, building codes and energy labeling frameworks, but the exact value is not universal and depends on the application, climate, and regulatory context.

In practice, referansetemperaturen is employed to standardize calculations of heat loss, heating or cooling demand, and to support simulations and performance modelling. By using a fixed reference value, results can be compared across different buildings, systems and climates under consistent conditions. It also supports reporting for energy certificates and efficiency labels, where a uniform baseline is required for fair comparison.

Determination of the referansetemperaturen is defined by standards or authorities for a given context. Values can vary by building type, room category, season, or climate zone, and are not the same as the actual thermostat setpoint or the measured indoor temperature. When applied, it is important to document the exact value and the rationale behind its selection, as this affects the interpretation of energy or performance metrics.

Overall, referansetemperaturen serves as a modelling and reporting parameter that enables consistency and comparability in assessments of energy use and thermal performance, without implying actual operating conditions.
