lämpömassamateriaaleja

Lämpömassamateriaalit, known in English as thermal mass materials, are substances used in building construction to store and release heat. Their primary function is to absorb excess heat during the day and release it slowly as the ambient temperature drops, or to store heat generated by a heating system and release it when the system is off. This helps to stabilize indoor temperatures, reducing the need for active heating and cooling systems and improving energy efficiency.

Common thermal mass materials include concrete, brick, stone, and water. These materials typically have a high heat capacity, meaning they can store a significant amount of thermal energy for a given mass. They also often have a high density and thermal conductivity, which facilitates the absorption and release of heat. The effectiveness of thermal mass depends on its placement within a building's design, often being incorporated into floors, walls, and ceilings, and its exposure to direct sunlight or internal heat sources.

The use of thermal mass is a passive design strategy that leverages natural thermodynamic principles. By moderating temperature fluctuations, thermal mass contributes to a more comfortable indoor environment and can reduce peak energy demands. Its application is particularly beneficial in climates with significant diurnal temperature swings, where the difference between daytime highs and nighttime lows is substantial. Proper design and material selection are crucial to optimize the performance of thermal mass in a building.
