Toteermalassa

Toteermalassa refers to a type of thermal mass used for storing heat energy in buildings. Also known as a thermal battery, it is typically a large container of heavy non-metallic material such as stone, concrete, or brick that is integrated into a building's structure.

The concept of toteermalassa is based on the principle of thermal mass, where materials absorb heat during the day through the sun's radiation or mechanical means and release it at night, reducing the need for heating or cooling. By utilizing the thermal mass, buildings can maintain a relatively stable internal temperature, reducing the load on heating and cooling systems.

The construction of toteermalassa involves filling a designated space, usually in a basement or in a foundation, with the chosen thermal mass material. The space is typically insulated to minimize heat loss. During the day, heat is absorbed by the material through conduction, and it is released at night, providing a regulating effect on the indoor temperature. This approach can be especially effective in regions with moderate climates or for buildings designed to be passive solar buildings.

In practice, toteermalassa can be an effective tool for building design and energy efficiency. Its primary advantages include reduced peak heating and cooling demands, ability to operate without electricity during off-peak times, and potential for hybrid and net zero energy configurations. Efforts to incorporate thermal mass into building design have existed for centuries, with notable examples from traditional architecture, such as in ancient Roman and Chinese structures where endurance and conservation of energy resources were key considerations.
