Summary: Advancements in residential net-zero energy buildings (NZEBs) are crucial for reducing energy consumption and greenhouse gas emissions, with design considerations including energy infrastructure connections, renewable energy sources, and energy-efficiency measures. A systematic literature review focused on recent progress in residential NZEBs is lacking, making this work aiming to provide references and support for wider and more successful implementation of residential NZEBs worldwide. The discussed categories include energy infrastructure connections like electrical grids and energy storage options, renewable energy sources such as solar and wind, and energy-efficiency measures like improved building designs and efficient HVAC systems. This paper highlights technology options to achieve residential NZEBs globally.

Summary: In the current energy transition towards carbon neutrality, the residential sector has a crucial role in combating climate change due to its significant contribution to global final energy consumption and direct CO2 emissions in the European Union. Polygeneration systems, which integrate renewable energies, offer an environmentally friendly and efficient use of natural resources. This study examines the economic viability and environmental benefits of an energy supplier company that acts as an aggregator for both demand and supply, owning a polygeneration system optimized through a MILP approach. Results show that the proposed configuration, including cogeneration, PV, heat pump, boiler, and thermal energy storage, is resilient and cost-effective, providing value for both the supplier company and final customers with reduced CO2 eq emissions.

Summary: Low-cost optimization measures have the potential to significantly reduce the need for invasive and costly retrofitting interventions. However, due to the lack of data collection processes and optimal implementation strategies, these measures are often underutilized. This study used a unique dataset of 92 residential buildings to identify the most effective actions for energy savings. By training an Artificial Neural Network and analyzing sensitivity indices, the study quantifies the impact of each measure on energy consumption variability and identifies the most probable intervals of energy savings.

Summary: The study uses a linear optimization approach to analyze the cost difference between shared energy infrastructure (smart energy neighborhoods, SENs) and individually planned buildings in idealized building clusters at different degrees of urbanization. With higher emission reduction targets, the advantage of SENs increases within rural environments and can reach up to 16%. However, there are scenarios where sharing energy infrastructure among buildings does not lead to economic advantages, such as in clusters with less than four buildings.

Summary: The share of residential building energy consumption in global energy consumption has rapidly increased after the COVID-19 crisis. Accurate prediction of energy consumption under different indoor and outdoor conditions is crucial for improving energy efficiency and reducing carbon footprints in the residential building sector. This paper proposes a PSO-optimized random forest classification algorithm to identify the key factors contributing to residential heating energy consumption. A self-organizing map (SOM) approach is used for feature dimensionality reduction, and an ensemble classification model based on the stacking method is trained on the reduced data. The stacking model outperforms other models with a 95.4% accuracy in energy consumption prediction. The research findings show a causal relationship between water pipe temperature changes, air temperature, and building energy consumption, providing valuable insights for residential building owners/managers in selecting efficient heating management systems to save on energy bills.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
