There is still a lot of research space and market demand for lightweight, heat-insulating, EMI-shielding construction materials. This paper develops compares the thermal insulation, ohmic heating effect, EMI shielding properties kind multifunctional sandwich material with “ROTIS” “FLAT” structures. The ROTIS-structured sample exhibits slightly higher conductivity than FLAT-structured sample, owing to its lower volume porosity plated copper content per unit area. Since ROTIS technology allows significant increase in thickness thinner raw materials, this structure an insulation Also, samples structures have better effect FLAT because active layer has more area, while less resistance. Unsatisfactorily, show electromagnetic effectiveness at 1-1.5 GHz, which mainly due their reduced porosity. In conclusion, materials that exhibit excellent shielding, properties, making them suitable use as building demanding indoor temperatures environments.

This study explores the impact of digital technology adoption on carbon footprint SMEs. Utilizing a framework aligned with ISO Standard 14040 for Life Cycle Assessment, research evaluates how different levels maturity Portuguese Ornamental Stone SMEs influence KPIs related to energy efficiency, production quality, material utilization, and emissions. Companies are categorized by their Digital Rank, ranging from DR#0 (no digitalization) DR#4 (advanced integration). The findings indicate that higher associated significant environmental operational benefits. For instance, companies at level achieve 35.1% reduction in emissions per unit output compared those DR#0. Additionally, these show substantial improvements producing more units kWh enhanced raw yield, minimizing waste optimizing resource use. results underscore transformative potential technologies promoting sustainability efficiency. integrate advanced tools not only reduce but also improve competitiveness productivity. highlights necessity comprehensive approach transformation, encompassing technological investments, organizational change, process optimization. provides actionable insights policymakers, industry leaders, leveraging goals. It emphasizes critical role digitalization supporting global transition low-carbon economy. suggests avenues future explore further integrated strategies long-term impacts sustainability.

Buildings consume 10% of global energy and 50% electricity for heating cooling. Transitioning to energy-efficient buildings is essential address the challenge meet sustainable development goals (SDGs) limit temperature rise below 1.5 °C. The shift from traditional smart grids has led micro, milli, nanogrids, which share resources symbiotically balance heating/cooling demands dealing with acute doldrums (dunkelflaute). This scoping review explores methods by phase change materials (PCMs) can be used in residential form a nanogrid. examines components concepts that promote seamless integration PCMs houses. It also discusses key challenges (e.g., scalability, stability, economic feasibility high summer temperatures), proposing community-scale network nanogrids (NoN) potential thermochromic photochromic materials. findings this highlight importance latent heat storage ingenious grid architectures such as construct resilient houses future thereby offer practical insights policymakers industries sector.
