The data collection was carried out in two stages. In the first one, the scientific literature was carefully examined to find candidates and their reported properties. In the second one, commercial PCMs available on the market were identified. The considered properties were melting temperature (ºC), melting enthalpy (J/g), specific heat in solid and liquid state (J/g·ºC), density in solid and liquid state (kg/m3), thermal conductivity in solid and liquid state (W/m·ºC), degradation temperature (ºC), and hazard level.
