Objectives
1. Build a monitoring plan for the GRI's efficiency to the UHI effect from 4 aspects: 1) Building heat; 2) Human health; 3) Plant's evapotranspiration; 4) Land surface temperature.
2. Provide a suggestion of data collection site.
Overall, this report provides a monitoring plan for the GRI's efficiency to the UHI effect within the St. George Street communities. By reading the article, doing the literature review, and simulating the previous research, we suggested it can study the GRI's impact on UHI from 4 aspects: building heat, human health, plant's evapotranspiration, and land surface temperature, based on their relative importance to the UHI effect. Our approach includes some factors that have significant influences on UHI and provides a suggestive monitoring plan for detecting how the local UHI will be affected after St. George Rainway's implementation.
Next Steps
1.The difference between building heat data's trend before and after the GRI implementation to identify the GRI implementation's efficiency. The GRI can be shown as effective if the trend of building heat data increasing rate after the GRI implementation is smoother than the data before GRI implementation.
2.The next step for the plant's evapotranspiration data analysis is similar to the building heat data. The evapotranspiration data's trends should be analyzed. Also, each different site will have a different evapotranspiration efficiency. Comparing all the data to determine which surrounding environment and GRI setting can have the highest evapotranspiration rate, also, the water resource consumption by plants should be considered. Then, for the future, a similar GRI setting can be added in St. George Rainway to enhance its effect on reducing the UHI effect.
3. After the introduction of the St. George Rainway, the land surface temperature for the surrounding communities should decrease, especially after rain, rainwater gathers in the rain-way to form a temporary open water and it is expected to stay longer than the rainwater on the road to cooling LST. It is recommended that the method of studying the cooling effect of water bodies be applied to more rivers, including streams and river water irradiated by sunlight. Finally understand the water bodies' cooling effect on UHI.
4. Due to the variety of heat-sensitive diseases, it is suggested that the project can cooperate with general practitioners (GP) and community hospitals to get related data with patient's knowledge. Furthermore, the overall mortality and morbidity of some acute diseases can be found based on BC Data ScoutTM or CareConnect programs. Referencing the COVID pandemic situation, an online survey through QR code can be randomly assigned to local residents between the ages of 18 to 75 years old. A pre-test of sensation can be made such as 'have you lost your temper within 12 h' to determine if a participant is emotionally 'normal' to do the survey. Weekly surveying is recommended to improve accuracy.
