Resumen:
This paper presents the geographical distribution of heating and cooling degree-days in Mendozas Metropolitan Area (MMA) taking into account the influence of urban heat islands intensity over the heating and cooling energy requirements in the city and quantifies the green house gases emissions derived from that impact.
The value of HDD and CDD has been calculated from temperature data recorded at 16 fixed weather stations installed within MMAs, measuring temperature and humidity in the urban canyons during a full yearly cycle. The calculation is performed using the Erbss method and the interpolated data for the considered metropolitan area are mapped using GIS software.
The results obtained have been compared with those obtained from the meteorological standards data computations, indicating that there is an under-estimation of CDD for the citys center of approximately 20% respect to the value obtained from the meteorological station values, and in the case of HDD there is an over-estimation close to 50%.Mendozas Metropolitan Area (MMA) taking into account the influence of urban heat islands intensity over the heating and cooling energy requirements in the city and quantifies the green house gases emissions derived from that impact.
