Typical Weather Year for the Design of Thermal Applications in Social Housing

Abstract

Andres Emanuel Diaz and Alejandro Luis Hernandez

The definition of a typical meteorological year (TMY) is essential for creating the climatic file used by Building Energy Simulation codes. The generation of the TMY was carried out using four different sets of weighting factors. This work is dedicated to defining the TMY for the city of Salta (1232 meters above sea level), to be applied in the design of social housing and solar air heaters. The data was based on information provided by the National Meteorological Service (SMN) of Argentina on various meteorological variables recorded at hourly intervals over an 11-year period (2006- 2016) at the Martin M. de Güemes Airport, while the radiation data was provided by the Institute of Non-Conventional Energy Research (INENCO). Based on statistical criteria, for each month of the year, one month from the sample is cataloged as a Typical Meteorological Month (TMM). The concatenation of the twelve TMMs defines the TMY. The generated TMY was applied to a simulation of a social housing unit. The results show the urgent need to apply energy efficiency criteria in social housing, as they present auxiliary energy loads ranging from -59 kW for cooling to 62 kW for heating.
