Summary: This study examines the time-frequency relationship among renewable energy, globalization, economic growth, trade openness, urbanization, and CO2 emissions in Asia using wavelet analysis. It finds substantial causal relationships between these variables in the short and medium runs. Additionally, it reveals that renewable energy and CO2 emissions are out of phase, with CO2 emissions driving the cycle. Furthermore, there is a positive co-movement between globalization and CO2 emissions, while trade openness is not significant in the long run.

Summary: In 2017, the Chinese government launched a clean heating campaign that replaced millions of rural coal stoves with clean heaters, leading to remarkable improvements in air quality. However, the study highlights the insufficient consideration of improving building envelope efficiency to reduce heating demand. It provides a quantitative assessment of the potential energy savings, costs, greenhouse gas emission reductions, and adoption strategies for improving building envelope efficiency in Chinese rural residential buildings.

Summary: Global warming is a pressing concern for world leaders, and financial efficiency, environmental regulations, and green technologies are recognized as important factors in improving environmental quality. A study has examined the impact of these factors on CO2 emissions and energy efficiency in highly polluted economies from 1995 to 2020 using the ARDL-PMG model. The findings suggest that environmental innovation and regulations improve energy efficiency and environmental quality in the long term, while financial development worsens environmental quality but improves energy efficiency. Therefore, policy experts in highly polluted economies should focus on increasing research and development, promoting green technologies, and implementing strict environmental regulations.

Summary: Photovoltaic systems generate electrical power from solar irradiance, but their efficiency is limited by surface temperature rise. It is crucial to review and evaluate cooling methods for optimizing system efficiency. Based on analysis, cooling techniques can improve electrical efficiency by 1% to 53% and reduce surface temperature by 1.8°C to 46°C.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.

Summary: This research introduces an innovative resilient design framework that optimizes building performance by considering a holistic life cycle perspective and accounting for climate projection uncertainties. The study finds that future climate scenarios significantly impact building life cycle performance, with wall U-value, windows U-value, and wall density being major factors. By using ensemble learning and optimization algorithms, predictions for carbon emissions, cost, and indoor discomfort hours can be made, and the best resilient design scheme can be selected. Applying this framework leads to significant improvements in building life cycle performance.
