Urban Building Energy Modeling Using a Place-Based Approach
Urban building energy models present a valuable tool for promoting energy efficiency in building design and control, as well as for managing urban energy systems. However, the current models often overlook the importance of site-specific characteristics, as well as the spatial attributes and variations within a specific area of a city. This approach allows for a more in-depth understanding of the interactions behind spatial patterns and an increase in the number and quality of energy-related variables.

Energy Transition in Greece
The global challenge of Reducing Greenhouse Gas (GHG) emissions, recent technological developments and cost reductions of Renewable Energy Sources (RES), the widespread diversification of gas supply sources and the demand for decentralized power generation are leading to a complete and irreversible phase-out from solid fossil fuels, i.e., coal and lignite. For the European Union (EU) regions with high dependence of their local economy on the solid fossil fuel industry, the process of decarbonization will require a significant productive diversification in the medium term and, above all, an immediate solution to the problem of thousands of jobs lost in the coming years.

A Smart Contract Architecture Framework for Industrial Symbiosis
Information Technologies (IT) seem to be promising to promote the development and implementation of the Industrial Symbiosis (IS) concept. For example, Blockchain technology (BCT) may have significant potential to help IS organizations collaborate and exchange data. This technology could provide a robust and reliable information management infrastructure. In particular, it could solve problems related to the lack of trust between organizations through its ability to ensure the immutability and traceability of data. In addition, through smart contracts, it can be useful to improve transparency, communication, awareness and security in IS networks.

Internet of Things Technologies in Green Stormwater Infrastructure
Incorporating smart tools and technologies into Green Stormwater Infrastructure (GSI) has been identified as a natural next step for stormwater management. A plethora of smart stormwater management systems have been proposed, mostly by integrating sensing, control, communication, and computing capabilities. These advancements can augment the operation, performance, and capacity of existing or new infrastructure through enhanced data capture, analysis, and control of infrastructure systems. These methods have been tested in the realm of water management for monitoring, controlling, and managing water volume and quality, and for supporting decision-making practices in water distribution networks.

Solar Wall Technology
Solar walls provide transformative solutions by harnessing solar energy to generate electricity, improve thermal comfort, and reduce energy consumption and emissions, contributing to zero-energy buildings and mitigating climate change. In hot and humid regions, solar walls can reduce indoor temperatures by 30% to 50%, significantly improving energy efficiency. Optimizing the performance of solar walls includes factors such as glazing, shading, solar orientation, ventilation, and catalytic techniques, allowing them to be adapted to different climates. Innovative solar wall variants that include photovoltaic panels, water storage, and phase-change materials offer multifunctionality and sustainability in building design and are in line with global energy efficiency and environmentally conscious goals.

Enhance the Efficiency of Thermophilic Anaerobic Digestion
Thermophilic anaerobic digestion (TAD) technology has been adopted worldwide mainly due to it being a pathogen-free process in addition to the enhanced biogas yield and short hydraulic retention time (HRT). Taking the high metabolic rate of the thermophilic microbial community with highly efficient enzymatic systems into consideration, thermophiles are being widely explored as efficient inocula for lignocellulosic biomass (LCB) degradation and improved biomethane production. The advantages of TAD over mesophilic anaerobic digestion (MAD), including improved kinetics, efficient degradation of organic matter, and economic and environmental sustainability, make it one of the best strategies to be operated at moderately high temperatures.

Decarbonization of Power and Industrial Sectors
Carbon dioxide (CO2) is the single largest contributor to climate change due to its increased emissions since global industrialization began. Carbon Capture, Storage, and Utilization (CCSU) is regarded as a promising strategy to mitigate climate change, reducing the atmospheric concentration of CO2 from power and industrial activities. Post-combustion carbon capture (PCC) is necessary to implement CCSU into existing facilities without changing the combustion block. In general, membrane separation is found to be the most competitive technique in conventional absorption as long as the highly-performed membrane materials and the technology itself reach the full commercialization stage.

Biological Methods of Producing Hydrogen from Biomass
Hydrogen is an environmentally friendly biofuel which, if widely used, could reduce atmospheric carbon dioxide emissions. The main barrier to the widespread use of hydrogen for power generation is the lack of technologically feasible and—more importantly—cost-effective methods of production and storage. Hydrogen has been produced using thermochemical methods (such as gasification, pyrolysis or water electrolysis) and biological methods (most of which involve anaerobic digestion and photofermentation), with conventional fuels, waste or dedicated crop biomass used as a feedstock. Microalgae possess very high photosynthetic efficiency, can rapidly build biomass, and possess other beneficial properties, which is why they are considered to be one of the strongest contenders among biohydrogen production technologies.
