Phase change materials (PCMs) represent an innovative solution to passively manage device temperature or store heat, taking advantage of the material phase transitions. In this work, attitude high density polyethylene (HDPE) for shape stabilization three selected organic PCMs with a melting close 55 °C was investigated. Composites PCM content in range 50-61 wt.% were produced by melt compounding, and lab-scale panels compression molding. The ability supporting olefinic matrix stabilize contain leakage verified compared through thermo-mechanical characterization. Moreover, expanded graphite introduced according novel under-vacuum impregnation process order provide extra stabilizing contribution, resulting outstanding thermal conductivity increase up 1.6 W/m·K, maximized enthalpy 112 J/g. Besides stability, HDPE also improves mechanical properties PCM-based composites, as documented detailed extended characterization cold hot tests, flexural Vicat shore A tests. management effect is quantified infrared thermography, proportionally relating lags melting/crystallization investigated products. view applications 30-60 °C, main different are summarized compared.

The building sector accounts for a significant proportion of global energy usage and carbon dioxide emissions. It is important to explore technological advances curtail support the transition sustainable future. This study provides an overview emerging technologies strategies that can assist in achieving decarbonization. main reviewed include uncertainty-based design, renewable integration buildings, thermal storage, heat pump technologies, sharing, retrofits, demand flexibility, data-driven modeling, improved control, grid-buildings integrated control. review results indicated these showed great potential reducing operating costs footprint. synergy among area should be explored. An appropriate combination help achieve grid-responsive net-zero which anticipated one best options simultaneously reduce emissions, consumption, costs, as well dynamic supply conditions energy-powered grids. However, unlock full collaborative efforts between different stakeholders are needed facilitate their deployment on larger wider scale.

The application efficiency of the Dynamic Rotating Latent-Energy-Storage Envelope (DRLESE) system is highly contingent upon dynamic rotation timings. To gain optimal timings, six different timings were examined by employing liquid fraction, thermal storage and release, surface temperature heat flow. numerical transfer method was employed verified an experiment. Results indicated that initial occurs in forenoon, when inner aligns with sol-air temperature. Subsequently, achieving secondary possible afternoon equals PCM (Phase Change Material). Under these optimized significant enhancements performance DRLESE observed. By optimizing indoor effective release can reach up to 3182.9 kJ/Day effectiveness percentage exceeding 99.99%, flow increased 5.86%–12.26%.

Lightweight envelopes are increasingly utilized in temporary relief and shelter buildings, due to their cost-effectiveness efficient construction process. However, these often result inadequate indoor thermal conditions during the summer months, which can negatively impact physical psychological well-being of occupants, particularly victims patients disaster or epidemic situations. Addressing this challenge necessitates use simple yet effective materials technologies improve environments even with limited resources. This study explores potential shading nets enhance lightweight buildings by mitigating solar radiation gain period. A comparative experiment was conducted on two one equipped standard six-needle black nets, assess environment air-conditioning energy consumption. The findings reveal that reduce intensity approximately 57.86 %, resulting a significant decrease peak air temperatures 2.3°C 3.4°C under natural ventilation reduction consumption up 23 % air-conditioned conditions. These demonstrate improving comfort reducing usage, providing practical solution for enhancing living structures hot weather.
