lämmitysaika

Lammitysaika is a Finnish term that translates to "heating season." It refers to the period of the year when buildings require artificial heating to maintain comfortable indoor temperatures. The exact start and end dates of the heating season can vary depending on geographical location, local climate conditions, and building specific regulations or practices. In Finland, where the term originates, the heating season typically begins in the autumn as outdoor temperatures drop and concludes in the spring when ambient temperatures rise sufficiently.

The commencement of the heating season is often triggered by a sustained average outdoor temperature falling below a certain threshold, commonly around +15 to +18 degrees Celsius. Similarly, the end of the season is determined by the average temperature consistently exceeding this range. Municipalities or housing associations may have specific guidelines or decisions regarding the official start and end of the heating period for their respective areas or properties.

During the lammitysaika, heating systems such as central heating, radiators, or underfloor heating are activated and operated to provide warmth. The duration and intensity of heating are influenced by factors like building insulation, window quality, and the efficiency of the heating system. Energy consumption for heating typically increases significantly during this period, making it a crucial factor in a building's overall energy usage and associated costs. Monitoring and managing heating during this time is important for both comfort and economic efficiency.
