Lämpömassavaikutus

Lämpömassavaikutus is a Finnish term that translates to "thermal mass effect" in English. It describes the property of a material to absorb and store heat energy and then release it slowly. This phenomenon is particularly relevant in building design and climate control. Materials with high thermal mass, such as concrete, stone, and brick, can absorb heat during the day and release it at night, helping to regulate indoor temperatures and reduce the need for artificial heating and cooling.

The effectiveness of thermal mass depends on several factors, including the material's specific heat capacity, density, and thickness, as well as the temperature difference between the material and its surroundings. In passive solar design, thermal mass is strategically placed to capture solar radiation during sunny periods. This stored heat is then gradually released when the ambient temperature drops, contributing to a more stable and comfortable indoor environment.

Conversely, in hot climates, thermal mass can absorb excess heat from the interior during the day and release it to the cooler night air. This moderating effect can significantly improve energy efficiency and reduce peak cooling loads. The implementation of thermal mass requires careful consideration of insulation strategies to prevent unwanted heat loss or gain. Proper design ensures that the thermal mass functions as intended, absorbing and releasing heat in a controlled manner to optimize energy performance and occupant comfort.
