Why not use this article as a prompt to explore issues and opportunities around thermal mass in existing buildings across the UK, and\/or those local to you?<\/p>\n

Maybe even look at adding further conservation-related links to the article, or even offering your own expert insight to the issue through an article in Conservation Wiki<\/a>.<\/p>\n

BRE writes via DBW:<\/p>\n

The thermo-dynamics of\u00a0thermal mass<\/a>\u00a0is a complex subject. The usefulness of\u00a0materials<\/a>\u00a0for storing\u00a0heat<\/a>\u00a0is based on the relationship between their thermal\u00a0properties<\/a>\u00a0and the thermal cycle that they are required to moderate.\u00a0 Thermal mass<\/a>\u00a0requires high\u00a0specific heat capacity<\/a>, high density and a thermal conductivity<\/a>\u00a0that means\u00a0heat<\/a>\u00a0flows into and out of the\u00a0material<\/a>\u00a0are aligned with the thermal cycle of the occupied\u00a0space<\/a>.\u00a0Materials<\/a>\u00a0such as\u00a0concrete<\/a>\u00a0and\u00a0masonry<\/a> tend to have a useful thermal mass<\/a>, whereas timber<\/a> is too slow an absorber of heat<\/a>, and steel<\/a> has a too high a thermal conductivity<\/a>\u2026.<\/p>\n

However,\u00a0thermal mass<\/a>\u00a0must be exposed to\u00a0function<\/a>\u00a0efficiently. This means that it is commonly associated with exposed\u00a0concrete floors<\/a>, and\u00a0walls<\/a>, rather than conventional\u00a0spaces<\/a>\u00a0which might include\u00a0wall<\/a>\u00a0linings,\u00a0suspended ceilings<\/a>\u00a0and\u00a0raised floors<\/a>. This requires that a high-quality<\/a>\u00a0finish<\/a>\u00a0is achieved and that\u00a0services<\/a>\u00a0are carefully routed. The effectiveness of\u00a0thermal mass<\/a>\u00a0can, however, be enhanced by\u00a0paint<\/a>, selected to optimise the absorption and release of\u00a0thermal radiation<\/a>\u2026.<\/p>\n
