- Techno-economic analysis of a renewable energy based multigeneration system for zero energy buildingsPublication . Aelenei, Laura Elena; Rodrigues, Carlos; Brites, Maria João de Sousa; Viana, SusanaABSTRACT: The present study explores the contribution and benefits of a renewable energy based multigeneration prototype integrating a luminescent compound parabolic concentrator, a photovoltaic/thermal system and thermal storage using phase change materials. A numerical model was developed for assessing the energy performance of the prototype and the results are presented for three different European locations. A simplified economic analysis was also developed and presented for two different scenarios and the same European locations. The results reveal that the installation of the IDEAS system in Lisbon, with a total estimated yearly use of solar energy of 1215 kWh and an amount of energy sold to the grid of 40.6 kWh, results in savings of 266 (26 % of energy bill). For the Ferrara location, with a total estimated yearly use of solar energy of 967 kWh and 19.8 kWh of energy sold to the grid of, results on 229 (16 % of energy bill) of annual savings. In Dublin, with a total estimated yearly use of solar energy of 862 kWh and an amount of energy sold to the grid of 20.5 kWh, results on annual savings of 257 (14 % of energy bill).
- Towards climate adaptation: a case study of a Coastal City in PortugalPublication . Aelenei, Laura Elena; Viana, Susana; Simões, Teresa; Amorim, Filipa; Simoes, Sofia; Barbosa, Juliana Pacheco; Justino, Paulo Alexandre; Goncalves, Helder; Dinis, J.; Fernandes, G.ABSTRACT: The present study focuses on the use of complementary numerical tools to support the development of a climate neutrality roadmap for Cascais, a coastal Portuguese city and one of the nine pilot cities in the Re-Value project. The results contribute to refining the roadmap and updating Cascais' long-term Territorial Transformation Plans to accelerate its journey to climate neutrality by 2050. For this, a spatial analysis was conducted to assess the potential for rooftop solar PV, onshore wind energy, and wave energy along the coastline. Additionally, an innovative and simplified Decision Support Tool (DST) was developed to support municipalities in the development of their climate neutrality roadmaps and was used in the design of the scenarios and trajectories, which are now being integrated into the climate neutrality roadmap for Cascais. The DST tool results show that in the High Development scenario, when compared with the reference year of 2019, the total final energy demand can decrease by 7.2 % in 2050 due to the implementation of energy efficiency measures following the concept "Energy Efficiency First" and along with the increase of electrification, the introduction of hydrogen in the transport sector, and a broader implementation of renewable energy in the urban fabric and public spaces, Green House Gas (GHG) emissions can decrease by 82 % in 2050.
