Abstract
The European Union’s decarbonization targets necessitate a rapid transformation of the
building sector toward net-zero emissions. This study presents a comprehensive techno
economic and environmental assessment of photovoltaic (PV), wind, and hybrid PV–wind
systems for energy-plus buildings in six representative Polish cities: Białystok, Katowice,
Lublin, Poznań, Szczecin, and Gdańsk. Using HOMER Pro simulation software, systems were
optimized to minimize Levelized Cost of Energy (LCOE) while maximizing renewable
fraction. Results indicate that inland cities achieve optimal performance with PV-only
systems (LCOE: 0.50–0.60 USD/kWh), whereas coastal cities favor wind-only systems
(LCOE: 0.65 USD/kWh) due to higher wind resource availability. Annual greenhouse gas
(GHG) reductions range from 89% to 94%, equivalent to 6.5-7.4 tonnes CO₂ per building.
Sensitivity analysis confirms the significance of capital cost reductions and financing
conditions for economic viability. Policy recommendations include targeted incentives, PV
ready building codes, and grid modernization. The findings provide actionable insights for
policymakers, investors, and engineers aiming to accelerate renewable integration in
Poland’s residential sector.
Rooftop solar photovoltaic (RSPV) systems are increasingly recognized as a vital component of the decentralized energy transition, enabling on-site electricity generation that minimizes transmission losses while advancing institutional sustainability goals. This paper presents a simulation-based techno-economic and env...

Nigeria building sector accounts for over 34% of electricity use and 18% of carbon emissions, yet 60% of urban buildings experience daily grid outages lasting > 12 hours. Net-zero energy buildings (NZEBs) offer a dencentivizing pathway while addressing energy access gaps, but feasibility studies for tropical developing...

Agrivoltaic systems (AVSs) present a promising solution to land-use conflicts between solar photovoltaics and agriculture. Nevertheless, their electricity-side cost performance is strongly influenced by site-specific conditions and agricultural constraints, and a comprehensive nationwide geospatial assessment of optima...
Reliable and sustainable electricity supply is essential for university campuses in developing regions facing grid instability, high energy costs, and environmental concerns. This study develops and evaluates a grid-connected hybrid renewable energy system for Raya University, Maichew, Ethiopia, integrating solar photo...
