Energiatehokkaan

Energiatehokkaan is a Finnish adjective meaning energy-efficient. It describes something that uses less energy to perform a given function compared with a reference level. The form energiatehokkaan is a inflected form used when modifying a noun, for example energiatehokkaan rakennuksen (an energy-efficient building) or energiatehokkaan laitteen (an energy-efficient device). The related noun energiatehokkuus refers to the quality or state of being energy-efficient.

In practice, energiatehokkaan characteristics are sought in buildings, appliances, vehicles and industrial processes. In Finland and in the European Union, energy efficiency is promoted through labeling, performance certificates and building regulations. Energy labels on products and energy performance certificates for buildings help consumers and operators compare efficiency, while requirements for insulation, airtightness and efficient systems aim to reduce energy use and emissions.

Common approaches to achieving energiatehokkaan performance include enhanced insulation and airtight construction, efficient heating and cooling solutions such as heat pumps and condensing boilers, ventilation with heat recovery, and low-energy lighting and appliances. Smart controls, energy management systems and efficient motors or drives also contribute. While the term appears in marketing, official assessments typically rely on defined metrics and standards to verify energy use reductions and to support comparisons across products and buildings.
