Lauryl alcohol and stearyl alcohol eutectic for cold thermal energy storage in buildings: Preparation, thermophysical studies and performance analysis

•Binary eutectic PCM with lauryl alcohol and stearyl alcohol was prepared.•The melting point and latent heat of fusion of eutectic PCM were 22.93 °C and 205.79 J g − 1.•The thermal conductivity is measured maximum up to 0.18 W m − 1 K − 1.•Charging and discharging of PCM was done in prototype room.•A temperature drop of 3.5 °C was achieved in prototype room.
