Integration between photovoltaic generators and building energetic retrofitting

Abstract

Almost 40% of world power consumption is related with buildings, some of them evaluated as poorly efficient and outdated. In that way, government entities had been stimulating modernizations with guidelines and standards modernizations, proposing with retrofitting and solar power to reach ZEB (Zero Energy Building). Energetic retrofits can save about 30% building power consumption, which with PV (Photovoltaic) generation turns reach ZEB easier, particularly to educational buildings. This paper explores the suggestion of an energetic retrofitting with PV generation to IK building of POLI-UPE (Pernambuco Polytechnic School-Pernambuco University). Considering PV generation, building efficiency and comfort parameters under economic indicators. Despite the process complexities, it’s possible to find a solution about strategies selection dilemma evaluating the building holistically from power consumption baselines, with a systematic methodology using market data that must be composed to figure out energetic and economic indicators beneath the proposed action backgrounds. The findings, overall seems that auto generation is fully reasonable and retrofit with, might affect positively the cost-saving if the intervention scenarios were rightly evaluated.
