Comparison between Energy-Plus Typical Meteorological Year and 15-years long-term data for Montevideo

Abstract

In this document we present a preliminary evaluation of the Typical Meteorological Years (TMY) dataset for Montevideo city, Uruguay, that is contained in the EnergyPlus building design software. Global horizontal irradiation (GHI), mean, maximum and minumum temperature, relative humidity and atmospheric pressure is considered. The time-series for these variables are compared with long-term data from the period between the years 2000 and 2015. Temperature, relative humidity and atmospheric pressure were measured in ground at a high-quality national conventional meteorological station in the Carrasco area (Montevideo). Global horizontal irradiation is estimated by satellite through a low-uncertainty model developed locally at the national Solar Energy Laboratory (LES, UdelaR) which uses visible channel images from the GOES-East satellite. This model has been proposed and evaluated in [1, 2, 3, 4].
