On March 14 2019, the cyclone Idai strucks the central region of Mozambique with tremendous force, causing widespread human loss and economic damages. The city of Beira received the full force of the cyclone and large areas within the municipal boundaries were flooded; as a consequence, most buildings in Beira were damaged and many were destroyed. In the weeks after the cyclone, an outbreak of cholera added to the disaster, and several dozens of people lost their lives. In the current situation, it is necessary to reconstruct the city center of Beira from its foundation and it has to be done in suitable and sustainable way. This thesis aims to contribute to the energy efficient and sustainable reconstruction of part of the city, in particular of the hystorical building of the Grande Hotel of Beira. Nowadays the Grande Hotel is in part destroyed and in part occupied by the refugees of the cyclone in really harsh hygiene and health condition without water and electricity. The idea is to built in this structure apartments, markets and community spaces where people can live in a better condition to improve life quality. This thesis, thanks to the collaboration of Lab Beira’s architects layout design (this is a joint initiative from Politecnico di Torino and Comunità di Sant’Egidio) , is focused on the apartments which will be part of the block B of the structure. The aim is to simulate their energetic consumption and make them as efficient as possible through the energy management by using the software EnergyPlus. EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption—for cooling, ventilation, lighting and plug and process loads. As far as energy supply is considered, the thesis aims to investigate the renewable power production from PV system which is sized through the software HOMER Pro and analysed by its affodability through economical parameters and costs and sensitivity analysis. Indeed, the sizing is based on the minimization of electricity supply cost also considering environmental effects such as greenhouse gas emissions. In conclusion, this thesis is a part of a bigger project which wants to give back to a large number of person who have lost almost everything a place where they can have ensured better lifestyle condition, electricity and space to reconstruct social, educational and economical improvement in the most efficient and sustainable way as possible.
