Summary: Under the moderate scenario, with 100% NZEB market penetration in 2050 and a 30-30-30 mid-term goal by 2030, energy consumption could save 13% by 2030 and 60% by 2050 compared to the conservative scenario. According to the propulsive scenario, in response to China's carbon emission target, the years 2025, 2030 and 2035 should be set as the governmental enforcement years for ultra-low energy buildings, NZEB and ZEB respectively.

Summary: With the aim of achieving carbon neutrality, bio-based construction materials like straw bales are gaining interest globally. However, the thermal conductivities of straw bales can vary greatly, which may affect their suitability for nearly-zero energy building (nZEB) design standards. This study conducted thermal property and carbon emission assessments of straw bale walls (SBWs) in northern China. The results showed that SBWs can meet nZEB design standards in the severe cold region after adjustments, and they have low carbon emissions and high thermal performance compared to other materials. These findings can contribute to the development of clean construction and net-zero design in northern China.

Summary: This paper assesses the impact of four selected stages of the life cycle of a NZEB building on the environment, showing that photovoltaic energy storage can have different effects compared to photovoltaic energy export, with a partial and total shift of impacts observed. While it reduces the impact of climate change, it significantly increases the depletion of abiotic resources. However, the use of stored energy in a lithium-based battery is beneficial in most categories of the building life cycle's total environmental impact, despite a relatively high impact increment during the replacement stage.

Summary: This study aimed to quantitatively analyze the carbon emissions and carbon reduction potential of a nearly Zero Energy Building in a severe cold region of China throughout its life cycle. Results showed that the total carbon emissions of the building over its whole life were 789.43 kg CO2/m(2), representing an 86.20% reduction compared to a 65% energy-saving building. The production stage and operation stage were found to be the major contributors to carbon emissions, accounting for 75.62% and 20.40% of the total, respectively. The study also revealed that using a wood structural system and increasing photovoltaic power generation can significantly enhance carbon reduction potential.

Summary: With the establishment of global carbon reduction targets, energy conservation and emission reduction of buildings have become essential. By using passive building design methods, nearly zero energy buildings (nZEB) can reduce energy consumption requirements. Traditional energy storage materials (CESM) or phase change materials (PCM) are used in building components to reduce indoor temperature fluctuations in the heating season. A simplified mathematical model was established to analyze the characteristics of indoor temperature distribution in nZEB affected by building components with or without nonlinear heat capacity. The results show that the maximum indoor temperature distribution frequency of PCM buildings is significantly higher and more concentrated compared to CESM buildings. By selecting the phase transition temperature close to the average indoor temperature in the heating season, the maximum indoor temperature distribution frequency, indoor comfort guarantee ratio, and latent heat utilization time ratio of PCM buildings can be significantly increased.

Summary: This paper quantitatively analyzes the mode substitution and carbon emission impacts of the electric bike-sharing system (EBSS) on urban transportation using survey data and operating data. The results show that the EBSS mostly substitutes short-distance trips from walking and conventional bike-sharing, and long-distance trips from cars, buses, and the subway. The partial-trip substitution impact on car travel is investigated, where the EBSS serves as a connection to public transit. Based on the analysis, the studied EBSS has significantly reduced CO2 emissions compared to other transport modes.

Summary: Surgical site infections (SSIs) lead to longer patient stays and higher hospital costs. Airborne microbe-carrying particles, mainly released from the surgical team, are a major cause of SSIs. Therefore, it is necessary to assess the amount of aerosol particles and microorganisms emitted by surgical staff. This study conducted experiments in a full-size operating room to evaluate four garment systems and nine movement combinations, presenting emission rates of particles and microorganisms as well as microbiome analysis by the surgical staff. Skin exposure areas and movement intensity significantly affect microbial and particle emissions. The findings contribute to the effective prevention of SSIs.

Summary: This study investigated the performance of upper-room ultraviolet germicidal irradiation (UVGI) for reducing SARS-CoV-2 virus transmission in a hospital isolation environment. The results showed that higher percentage of virus could be inactivated by the upper-room UVGI at a lower ventilation rate, and the rate of improvement of UVGI elimination effect slowed down with the increase of irradiation flux. Increasing irradiation height at lower ventilation rate was more effective in improving the UVGI performance than the increase in irradiation flux at smaller irradiation height.

Summary: Airborne transmission is a common way of spreading infectious diseases, especially in closed environments. However, the impact of background particle concentration on bioaerosol characteristics has been overlooked in previous research. In this study, we compared the distributions of bioaerosols under heavily polluted and excellent background particle concentrations. The results showed a significant reduction in bioaerosol concentration and a higher decay rate under heavily polluted levels. The study also found differences in the size distribution of bioaerosols between the two levels of background particle concentration.
