# Monitored hygrothermal dataset of a high-altitude Dolomite refuge: wall and indoor climate at 2870 m a.s.l

## TL;DR

This paper presents a five-year hygrothermal dataset from a high-altitude mountain refuge in the Dolomites to study climate and building performance in extreme alpine conditions.

## Contribution

The study provides a rare, long-term, high-frequency hygrothermal dataset from a high-altitude heritage building.

## Key findings

- The dataset includes hourly hygrothermal measurements from outdoor and indoor environments over five years.
- It enables validation of hygrothermal models and evaluation of insulation performance in historic masonry structures.
- The data offer insights into moisture-related risks in high-elevation heritage buildings.

## Abstract

A five-year hygrothermal dataset (23 September 2020 to 8 August 2025) was compiled from Rifugio Boé, a 1905 stone mountain refuge situated at 2870 m a.s.l. in the Dolomites. The dataset includes hourly recordings of outdoor climate parameters (temperature, relative humidity, global tilted irradiance, and driving rain), indoor conditions across six functionally distinct rooms, and temperature–humidity profiles at three depths within the retrofitted south-east wall. The monitoring system was engineered for robust, long-term operation under harsh alpine conditions. Data are provided in CSV format, accompanied by comprehensive sensor metadata. The dataset supports: (i) validation of hygrothermal simulation models under extreme alpine conditions; (ii) evaluation of the long-term performance and durability of internal insulation within historic masonry; and (iii) benchmarking of moisture-related risk in high-altitude heritage structures. Moreover, the dataset offers a rare opportunity to examine hygrothermal responses in high-elevation-built heritage, a research domain where long-term, high-frequency data remain scarce.
