The aim of the study is to quantify the influence of the uncertainties associated with the measurements of the thermo-physical properties of PCM on the results of the annual energy consumption. For this purpose, EnergyPlus has been used for the building energy simulation and a Monte Carlo based method has been chosen for the uncertainty and sensitivity analysis. Considering realistic uncertainty ranges for PCM thermo-physical properties, a significant uncertainty of savings on cooling energy demand has been calculated (approximately 10%). Phase change temperature and thermal conductivity have been identified as the most influential input parameters whereas phase change enthalpy is of secondary importance. A method has been proposed in order to calculate a combination of admissible uncertainties for the input variables that reduces output uncertainty to a required value. The method can be used if input variables and the behaviour of the model comply with certain conditions. For the case study, a maximum tolerance for the error of measurements of phase change temperature and thermal conductivity of ±0.3 °C and ±8% respectively is necessary to reduce the uncertainty of savings on cooling energy demand to 5% 000168555 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/ENE2011-28269-C03-01$$9info:eu-repo/grantAgreement/ES/MICINN/ENE2011-28269-C03-03 000168555 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000168555 590__ $$a3.043$$b2015 000168555 591__ $$aENGINEERING, MECHANICAL$$b7 / 131 = 0.053$$c2015$$dQ1$$eT1 000168555 591__ $$aTHERMODYNAMICS$$b6 / 57 = 0.105$$c2015$$dQ1$$eT1 000168555 591__ $$aMECHANICS$$b7 / 135 = 0.052$$c2015$$dQ1$$eT1 000168555 591__ $$aENERGY & FUELS$$b30 / 88 = 0.341$$c2015$$dQ2$$eT2 000168555 592__ $$a1.683$$b2015 000168555 593__ $$aIndustrial and Manufacturing Engineering$$c2015$$dQ1 000168555 593__ $$aEnergy Engineering and Power Technology$$c2015$$dQ1 000168555 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000168555 700__ $$aEl Badry, A.
