【正文】 reen Area (Pudong) Technology Indoor air quality can be improved with the presence of plants。 Studies show that the presence of plants increases employee work performance by 12%, increases productivity and reduces stress. GREEN CITY: the positive effect of green on INDOOR AIR QUALITY Shanghai EXPO 2022 Central Green Area (Pudong) Technology Ventilation is increased in a building by planting trees outside the building (prefiltering and temperature reduction) and inside the building (in open areas, hallways and individual rooms。 Leaves release transpiration which provides humidity in the air。 Indoor plants reduce dust in a room by 20%, and absorb benzol, nicotine and other volatile gasses. Air pollution is absorbed by the leaves of the plant Dispensing of water damp by transpiration of the leaves Convection streams by transpiration of the leaves transport the pollution into the root zone Micro anisms around the roots pull down the pollution and convert it into nutrients GREEN CITY: the positive effect of green on INDOOR AIR QUALITY Shanghai EXPO 2022 Central Green Area (Pudong) Technology Green makes people feel good (515%)。 green increases recreation, encourages exercise and healthier lifestyles Green decreases doctor visits。 Hospital patients with a “natural green view” recover faster and require less pain relief。 Green benefits the wellbeing of residents, builds munities and advances social neighbours。 Green creates more safety and has a positive influence on vandalism。 Improves aesthetic quality of urban area Green links cities and villages with nature, creating responsible ecosystems The creation of sustainable examples educates future generations GREEN CITY: the positive effect of green on MENTAL AND PHYSICAL HEALTH Shanghai EXPO 2022 Central Green Area (Pudong) Technology Green projects in the city create startup jobs (soil preparation, planting, etc.) as well as perma nent employment (maintenance, manage ment, etc.)。 The longterm benefits of trees in the city are more than twice the Present value of costs。 Green increases property values。 Green provides more tax revenue for a city。 Green improves the economy of surrounding areas。 Green encourages inward investment。 Green reduces public spending on healthcare and social services。 Green increases tourism. GREEN CITY ECONOMIC EFFECTS Shanghai EXPO 2022 Central Green Area (Pudong) Technology Flood control。 Green catches water and deposits it in the soil (impervious surfaces allow 55% runoff while soil and green has only 10% runoff。 Green creates less need for city drains (+/ 20%) and less storm water construction works。 Water can be cleaned/purified with green (814%)。 Trees in cities can help protect urban water supplies, wastewater treatment systems and storm water management。 Purified water from green can be reused to water the urban forest Flood control. GREEN CITY: WATER MANAGEMENT AND WATER QUALITY Shanghai EXPO 2022 Central Green Area (Pudong) Technology Building energy use is reduced with trees by shading buildings, altering air flows and lowering air temperatures through transpiration (and eventually less pollution emissions from power plants)。 Roof gardens regulate temperatures inside buildings reducing energy costs Planting trees could reduce the need for power plants GREEN CITY: ENERGY SAVING Shanghai EXPO 2022 Central Green Area (Pudong) Technology Trees, leaves and grass create biomass which is the basis for renewable biomass energy。 Biomass absorbs CO2 GREEN CITY: BIOMASS ENERGY Shanghai EXPO 2022 Central Green Area (Pudong) Technology Wel of niet green city TEMPERATURE WIND Sheltering Effect Plantation (red area = sheltered area) Shanghai EXPO 2022 Central Green Area (Pudong) Technology +20% 70% 50% 30% 20% 10% H +20% 0H 5H 10H 15H wind direction green city TEMPERATURE WIND Shanghai EXPO 2022 Central Green Area (Pudong) Technology 20220625
