Summary: This study proposes a new method using TRNSYS integrated with MATLAB thermal model to calculate the energy saving for buildings with spectral-dependent radiative cooling roofs. The energy-related strengths and weaknesses of applying such materials on the rooftop under various climatic and insulating conditions have been revealed. It provides reference and guidance for energy-oriented decision-making process for implementing radiative cooling roofs.

Summary: The review focuses on synthesis methods for pigments used in cool roofs, aiming to find the best method in terms of energy and raw material costs. The emphasis is on inorganic NIR reflective pigments without harmful metals, and the manuscript serves as a practical tool for selecting pigments based on colorimetric parameters, near-infrared reflectance values, energy-saving, and minimal waste synthesis routes.

Summary: This paper presents a numerical investigation of dew formation on building roofs and its impact on thermal and energy performance. A new semi-analytical model was developed to evaluate the effects of rooftop dew. Case study simulations showed that dew significantly influenced predictions of benefits and penalties of a 'cool roof'. Neglecting dew effects resulted in overestimating electricity savings and gas heating penalties associated with a cool roof. The study highlights the importance of considering dew's thermal effects in building performance simulations and provides a simple model to include these effects.

Summary: In this study, a series of Cr and Mg co-doped YAlO3 red pigments were synthesized by the co-precipitation method, and their color properties and solar reflectance were regulated by adjusting the amounts of Cr and Mg. The incorporation of Mg2+ promoted the generation of high-valent Cr ions and reduced absorption tail caused by oxygen vacancy. The red pigment with the composition of 3Cr-2Mg exhibited a good redness and high near-infrared reflectance.

Summary: The study investigates the potential of integrated passive technologies, such as cool roofs, natural ventilation, and solar shading, to reduce energy consumption in buildings. Field measurements and multi-objective optimization were conducted to evaluate the energy-saving effects. The results indicate that cool roofs and natural ventilation can significantly reduce air conditioning energy use. By implementing optimal design schemes, the energy consumption of the top floor room can be reduced by up to 52.3 kW h/(m(2)center dot yr).

Summary: This study develops highly efficient infrared (IR) stealth composites with low emissivity and thermal insulation by combining silver-plated hollow glass microspheres (HGM-Ag) and waterborne polyurethane (WPU). The composites have an asymmetric structure, with HGM-Ag concentrated on top as the low emissivity layer and a bottom layer with low thermal conductivity serving as the thermal insulation layer, providing outstanding mechanical properties.

Summary: The study finds that in warm climates, roof reflectivity is equally important as roof insulation; for low-rise offices and schools, reflective roofs have clear energy-saving advantages over dark-colored roofs in all US climate zones; while for big-box retail buildings, reflective roofs perform better except in cold climate zones 7-8.

Summary: Cool roofs are an effective long-term solution for reducing energy consumption and mitigating the urban heat island effect. Most of the current research focuses on either the building or city scale, with limited studies integrating both scales. It is crucial to establish a multi-level, interdisciplinary assessment framework that connects the urban microclimate with building energy efficiency.

Summary: The concentrations of elements in stream sediments are influenced by complex geological processes and various lithological sources, leading to skewed distributions. This can be attributed to multiplicative dilution effects creating lognormal distributions and a mix of populations from different geological processes and lithological sources. A method was proposed to classify sediment geochemical samples into domains with normal, lognormal, or log-ratio normal distributions, using mixture modeling, CLR transformation, and the EM algorithm. The results showed mixture models of 2-3 populations associated with main geochemical processes and lithological sources, setting threshold values for each domain and identifying anomalies in data that would not have been otherwise apparent.
