Correction: Sciurpi et al. Assessment of the Suitability of Non-Air-Conditioned Historical Buildings for Artwork Conservation: Comparing the Microclimate Monitoring in Vasari Corridor and La Specola Museum in Florence. Appl. Sci. 2022, 12, 11632

There was an error in the original publication [1]. In some points of the text, reference was made generically to the standard UNI EN 15757:2010, and this could confuse the reader by providing an imprecise interpretation of the standard itself. Indeed, in our study, we provided a different interpretation and application of this standard, and we believe that this aspect was not clearly explained in the original version of the manuscript. In particular, unlike UNI EN 15757:2010, our statistical analysis was performed on an annual basis rather than using the central moving average of readings taken in a 30-day period, as suggested in the cited standard, because our aim was to identify the threshold values of the historical climate range to be compared with the reference values recommended by the Italian D.M. 10.05.2001.

Accordingly, the following text corrections have been made to the original publication.

A correction has been made to Section 2.4, Paragraph Number 3:

Therefore, the data were also analyzed using the statistical parameters 93rd and 7th percentiles suggested by the standard UNI EN 15757:2010 [17], which applies a different approach based on methodological indications derived from the scrupulous analysis of the conservation environment [42]. However, unlike UNI EN 15757:2010 [17], the statistical analysis was performed on an annual basis rather than using the central moving average of readings taken in a 30-day period. Indeed, the aim was to identify the threshold values of the historical climate range to be compared with the reference values reported in Table 5.

A correction has been made to Section 2.4, Paragraph Number 5:

Thanks to the microclimate monitoring for at least 1 year in both buildings, it was possible to define the annual reference values of the historical climate for both museums, as detailed in Section 3, and use it to propose energy efficient control strategies for the indoor environment when minimizing the use of HVAC systems.

A correction has been made to Section 3.1, Paragraphs 5 and 6:

A further contribution to the analysis of the measured data is the determination of the historical climate of Vasari Corridor, i.e., the target values included in a statistical range defined by the values of the 93rd and 7th percentiles, as described in Section 2.4. In the case of the need for installation of HVAC systems, it is possible to dimension them in order to regulate the microclimatic control as a function of the historical climate typical of each monitored environment, instead of standard reference values.

Figures 11 and 12 show the trend of monthly and annual mean values of T and RH, respectively, for Lungarno (A) and Ponte Vecchio (B). Figures 13–16, instead, depict the range of oscillation of T and RH for positions A and B included in the 93rd and 7th percentiles.

A correction has been made to Section 3.2, Paragraph 6:

The ranges of oscillation of T and RH included in the 93rd and 7th percentiles, as described in Section 2.4, for rooms X and XXII are shown in Figures 22–25.

A correction has been made to Section 3.3, Paragraph Number 5:

On the contrary, considering the reference values calculated on the basis of the historical climate, as described in Section 2.4, for both museums, the yearly PI values are quite high, with PI_T ranging from 84% (position B and room XXII) to 87% (room X), and PI_RH ranging from 86% (position A and room XXII) to 88% (room X).

A correction has been made to Section 4, Paragraph 5:

However, given the current energy crisis, which could even prevent the opening of smaller museums due to unattainable operation costs, to minimize the energy consumption, while preserving the artworks, this work suggests the use of a different, more variation-tolerant approach. This approach is based on the analysis of the historical climate within the exhibition zones as described in Section 2.4.

The citation has now been inserted in Section 2.4, Paragraph Number 3 and should read:

The applicability of the latter, however, has been questioned in the existing literature [42,43].

With this correction, the order of some references has been adjusted accordingly.

The authors state that the scientific conclusions are unaffected. The Academic Editor approved this correction. The original publication has also been updated.
