CREATION OF A TYPICAL METEOROLOGICAL YEAR IN SPAIN. STEP BY STEP APPLICATION OF THE METHOD BASED ON UNE-EN ISO-15927-4:2011

Abstract

Perceptible acceleration of the climate change process makes it necessary to update climate files, which are used, for example, for energy simulation of buildings. The process of preparing a climatic file associated with a geographical location and referring to a period of time, is a laborious task, which begins with the construction of what is known as the Reference or Typical Meteorological Year (TMY) representative of said time frame. The TMY results from the concatenation of the twelve Typical Meteorological Months (TMM) representative of that cycle: the "best" month of January, the "best" month of February, March, etc. This paper presents an example indicating, step by step, an applicable procedure in Spain for the creation of an TMY, taking as reference the guidelines contained in the UNE-EN-ISO-15927-4:2011 Standard. The description is included of the use of the Finkelstein-Schafer statistic as a selection criterion for the best candidate months (with the novelty that in this work a literal application is made of the procedure) and finally a comparative study that gives an idea of the degree of suitability of the AMT selected according to the Standard. Key Words: energy simulation, reference climatic file, Typical Meteorological Year, UNE-EN-ISO-15927-4
