<p>The decarbonization of warehouse and logistics buildings is becoming an important component of climate policy and energy security. This paper evaluates the potential for transforming a representative warehouse building towards annual net-zero electricity performance through the combined application of energy efficiency measures, rooftop photovoltaics and a battery-supported sensitivity scenario. The study is based on a model logistics facility with a floor area of 10000 [m] and includes an annual electricity balance, a simplified temporal interpretation of demand–generation mismatch, an operational carbon assessment and a techno-economic evaluation. The model represents a warehouse facility located in a Central European climatic context, and the operational carbon assessment uses a grid emission factor of 0.40 kg [CO₂/kWh]. The modernisation package comprises LED lighting, intelligent lighting control, HVAC optimisation, destratification, compressed air system improvement and a rooftop photovoltaic system. In addition, a simplified battery-supported scenario was analysed in order to assess the effect of storage on self-consumption and grid imports. The results indicate that annual electricity demand can be reduced from 1200 to approximately 800 [MWh/year]. A rooftop PV system with a capacity of about 1.04 [MWp] can generate approximately 1040 [MWh/year], which allows the building to achieve annual net-zero electricity performance in the reference case. In the no-storage scenario, direct on-site PV utilisation reaches 750 [MWh/year], while in the battery-supported scenario, the annual battery-supported PV supply to the load increases and residual grid imports are eliminated in the simplified model. The efficiency package reduces operational carbon emissions by about 160 [t CO₂/year]. The techno-economic indicators reported in the paper pertain to the efficiency-plus-PV package without battery storage and remain favourable under the adopted assumptions, with a simple payback period of less than 4 years. The study confirms that warehouse buildings can significantly improve their operational energy performance and, under favourable technical conditions, become active elements of distributed energy systems. The efficiency-plus-PV package yields an indicative NPV of approximately 1.8 million EUR and an IRR of approximately 24% under the adopted assumption.</p>
