SUMMER LOAD EVALUATION IN THE ITALIAN CLIMATE: SENSITIVITY OF THE ENERGY PERFORMANCE TO THE WEATHER DATA

Pubblicazione


Autore: A. Prada, G. Peringotto, P. Baggio, A. Gasparella

Collana: CA - 66 - Rende 2011

Note:
In this paper, the influence of several parameters on the energy performance and the reliability of a quasi steady state approach for the prediction of cooling loads are analyzed. In particular, the sensitivity of the energy performance of the
envelope (EPe,inv) to weather data, both for light and massive buildings, is investigated.
In this sensitivity analysis, the real trends and periodic variation of the main external weather variables, such as dry bulb temperature and solar radiation, are used. Several simulations with different levels of mean value and amplitude of each external forcing factor and various combinations of weather variables are performed, in order to study the influence of each parameter.
From these results, some considerations are presented on the reliability of the quasi steady methods applied to energy need calculations for the summer season, in particular in Mediterranean region.
