The buildings sector is receiving important attention in the development of sustainable energy efficiency policies. Historic buildings and churches constitute a problem because they have enormous volumes, the envelope has low efficiency and for their nature such buildings escape from the legislative framework. This paper discusses the main findings of the EU funded project Friendly-Heating. Heating only finalized to the thermal comfort of churchgoers is not compatible with conservation: the higher the comfort level, the stronger the departure from the historical climate and the higher the risk for conservation. The importance of keeping the unchanged the historical climate is stressed by the European standard EN 15757: 2010 “Conservation of Cultural Property — Specifications for temperature and relative humidity to limit climate-induced mechanical damage in organic hygroscopic materials”. A compromise should be necessarily found between different needs, i.e. thermal comfort, artwork conservation, energy saving and cost. Thermal comfort is negatively correlated with all other needs, the others going all in the same direction. An optimisation can be found by controlling the heat dispersion: instead to heating the whole building, it is convenient to keep heat localised around the congregation and reduce dispersions as far as possible. Instead of using systems that require continuous operation, it is more convenient to use only local, occasional heating. Artworks will safely remain in their historical climate; a small quantity of heat will reach and cross the envelope, thus reducing energy consumption and cost. Churchgoers may have some heat, especially on feet and legs and heavier clothing too may be helpful to optimise the balance towards a better advantage. The above concepts have inspired the European standard EN 15759: 2011 “Conservation of cultural property – Specification and control of indoor environment – Part 1. Heating of churches, chapels and other worship buildings”.
