Regular visits to park green space offer remarkable benefits for the physical and mental health of urban residents. Achieving a comprehensive understanding utilization across entire city is prerequisite improving overall rate spaces. Traditional social survey methods are limited by their sample size time-consuming nature, while based on geographic location big data gaining momentum. This study focuses Xuchang, medium-sized in China, systematically analyzes current state influencing factors...

In China, rapid urbanization brought about the problems of increased building energy consumption and decreased area green space as well poor air quality heat island effect. Building envelope integrated plants (BIGP), which is also called vertical greening, regarded potential solution to environmental issues. This article verifies analyzes saving BIGP in China's hot summer cold winter regions through comparative experiments between a greening room reference room. The time experiment was...

Precipitation phase in China has changed with global warming, and accurate partitioning of the precipitation is crucial for understanding hydrological processes energy balance. Based on a 36-year daily meteorological dataset from Meteorological Administration, this study conducted comprehensive evaluation six empirical methods estimating nationwide explored applicability distinction across different meteorological, topographic geographic categories. These utilized inputs air temperature, two...

Greater attention is currently being paid to the relationship between indoor environment and childhood allergies, however, lack of reliable data disparity among different areas hinders assessment relationship. This study focuses on effect pollution Chinese schoolchildren specific household health problems suffered. The epidemiological questionnaire survey field measurement thermal primary air pollutants including CO2, fine particulate matter (PM2.5), chemical fungi were performed in six...

As one of the most widely used units in water cooling systems, closed wet towers (CWCTs) have two typical counter-flow constructions, which spray flows from top to bottom, and moist air flow opposite direction vertically (parallel) or horizontally (cross), respectively. This study aims present a simplified calculation method for conveniently accurately analyzing thermal performance types CWCTs, viz. parallel CWCT (PCFCWCT) cross (CCFCWCT). A capacity model that just includes characteristic...

Good indoor air quality is very essential to shoppers. In order characterize the in shopping malls, a typical mall Changsha city was selected for this study. Indoor/outdoor PM2.5 concentrations and meteorology parameters were monitored autumn, 2014. Diurnal variation of concentration both different functional areas outdoor discussed. Outdoor average at any time higher than that indoor. Indoor on weekend greater weekday. Among areas, cosmetics area highest, followed by dining area, public...

Building energy consumption in China has been increasing rapidly. And a small increase the operation efficiency of air-conditioning system can substantially decrease it. In this paper new type heat pump is developed to improve performance conventional air-source pumps. The major components heat-source tower units are closed-type (cold and sources absorption equipment) low temperature source. According relevant national standards, thermal parameters were experimentally studied, such as total...

The impacts of greenery systems (GSs) on microclimate conditions and building energy performance have been frequently investigated using experiments simulations during the past decades, especially in summer winter. However, few studies focused GSs transition seasons. ambient weather vary with great fluctuations seasons, which may result severe oscillations indoor environments. To investigate environments, an experiment was conducted a contrastive test platform, consisted two experimental...

A field investigation on indoor environmental conditions was performed in homes with primary school children Changsha, a city located central-south China. The main purpose is to obtain more reliable and comprehensive data relating the health of children. results showed that average temperature, relative humidity carbon dioxide concentration October were 20.4°C, 56.7% 398 ppm, while January 10.5°C, 55% 475 respectively. monitored PM 2.5 concentrations greater than Chinese national standard GB...

Groundwater-surface water (GW-SW) interaction, as a key component in the cold region hydrologic cycle, is extremely sensitive to seasonal and climate change. Specifically, dynamic change of snow cover frozen soil bring additional challenges observing simulating processes under GW-SW interactions regions. Integrated models are promising tools simulate such complex study system behaviours well its responses perturbations. The integrated should be physically representative fully considering...

Air movement dries surfaces by increasing evaporation and convection, which may prevent mould growth. Cladosporium sp. is used as the test organism (dominant fungi in envelope of rural houses hot summer warm winter areas), effect fans on inhibiting growth building materials investigated. Surface was simulated compared after rain leakage surface condensation, spore germination studied high humidity, with or without airflow. The results are follows: (1) Airflow has an evident inhibitory wet...

Equitable and high-quality medical services are more urgent in underdeveloped cities for the higher population ageing demanding social justice. However, there is little attention paid to multi-level services, particularly regarding time indicators under latest policies cities. The improved efforts were hampered partly by single scenario of location optimization, ignoring integrated optimization both road infrastructure institution location. Toward healthy China 2030 rural revitalization...

The Qinghai-Tibetan Plateau (QTP) is the highest plateau in world and has been recognized as "Asia water tower". Frozen soils China are mostly distributed on QTP, which considered sentinels of global climate change. Thermo-hydrologic (TH) processes frozen prominent for improving mechanistic understanding subsurface hydrology QTP. In this paper, an in-house developed high-resolution cryo-hydrogeological model was implemented into open-source, massively-parallel computational fluid dynamics...
