Résumé

The simplest form of thermal storage is to use the walls, floor and roof of a building as a thermal store. The structural shell of a commercial building typically has a design life of 50 years, and represents 45% of the initial construction cost. The air conditioning plant makes up 20% of the cost of construction, but will have to be replaced twice during the life of the building. Thermal storage systems may impose an additional cost on the initial construction of around 10%, but over the life of the building may yield substantial savings. In human comfort terms, passive cooling systems offer greater thermal stability. In addition, radiative cooling from a thermal store is associated with higher levels of occupant satisfaction than air-based comfort cooling systems.
