  • Description

    • Every type of energy simulation invariably requires some information on meteorological data such as temperature, solar radiation, humidity, wind speed and direction. Meteorological data are usually collected by agencies, national or regional, using meteorological stations that record information on an hourly or sub-hourly basis. However, historical recorded meteorological data cannot be used directly for energy simulation, but must be processed to obtain appropriate input files ready to be used in numerical codes and with variable characteristics depending on the type of calculation to be performed. Nowadays, the most used climatic data file for energy simulation is the so-called TMY (Typical Meteorological Year) that represents an average year obtained using data recorded in different years, but a different approach must be used to provide the climatic data needed for sizing HVAC system components or to compare energy simulation results with measured data. The objective of this course is to introduce students to some important aspects of meteorological data typically used in simulations, focusing on TMY and sizing procedures. The course will cover the generation and use of TMY data files and the definition of Design Days for plant sizing. To consider the effects of climate change, the course will also address methodologies for generating future climate data that allow simulations in future climate scenarios.
