Synthetic scan and simultaneous index aimed at the Indoor Environmental Quality evaluation and certification for people and artworks in heritage buildings

Maintaining a fixed indoor climate in historic buildings, especially if collections are housed is still an open scientific debate. The environmental management based on building historic microclimate and the one related to human thermal adaptation capability, may increase the time frequency of simultaneous comfort for people and collections leading to a new generation of Indoor Environmental Quality (IEQ) management and certification. Nevertheless some methodological unsolved issues related to the onsite activities aimed at assessing microclimatic quality either for people or for artefacts, as well as the conflict of parameters importance to consider during the certification process, leave room open to interpretation and arbitrary decisions. In this study a methodology for microclimate evaluation and certification with regard to people and heritage is proposed. The presented method, is based on the analysis of the physical attributes deviation from the optimal/safe levels. The final indexing can be supportive during regular-base microclimatic controls throughout different building spaces and time period.
