Energy and Environmental Analysis of Renewable Energy Systems Focused on Biomass Technologies for Residential Applications: The Life Cycle Energy Analysis Approach

Sustainability and resilience are major challenges for the building sector in order to meet energy efficiency low carbon emissions goals. Based on defined quantified targets of EU climate change policy, Renewable Energy Systems (RESs) among top-priority measures accomplishing target decarbonization buildings. Nevertheless, choice type RES is not a one-dimensional problem, optimal combination may be unique. The aim this paper environmental evaluation renewable technologies with emphasis biomass solar thermal systems heating applications residential More specifically, aiming at maximum possible contribution sources total final consumption needs zero buildings, different scenarios presented based Life Cycle Analysis (LCEA) approach. methodology quantifying impacts (midpoint analysis), as well endpoint analysis, define impact human health, ecosystem damage, resource depletion. LCEA has been conducted, supported by SimaPro tool, ensuring assessment result. A examined compared conventional fossil fuel according technical, energy, criteria. Finally, system were correlation building’s insulation level. first set simulations fulfilled minimum requirements, national performance regulation, whilst second was increased levels insulation. point analysis correlate technologies’ contribution. results determined that best available solution, focusing technical criteria, covering processes combined biomass–solar lower overall impact, due reduction gaseous pollutant emissions, amount used fuel. amounts percentage approximately 43%.
