1. Field Work- Microclimate study @ HCI Group 5: Hefan, Isaac Yu, Dylan, Kaicheng

2. Areas that have a concrete surface are generally hotter than areas that have a non-concrete surface. Hypothesis

3. Over 2 30-minute periods on the 16th and 17th January, we collected temperature data at various locations within the school campus, taking note of various factors that would have affected the temperature of that location (e.g. Cloud cover, surroundings, surface material etc.) Overview

4. The top deck of the Multistory Carpark (MSCP) has a concrete surface. There are many cars along the side of the deck. The area is completely exposed to sunlight and there is hardly any shaded areas. Area 1 : Multistory Carpark Temperature day 1 15 cm above ground: 34.6 degrees Temperature day 2 15 cm above ground: 28.0 degrees 1.5m above ground: 34.0 degrees 1.5 m above ground: 27.7 degrees

5. The garden has a grassy surface with dense vegetation growing on it. There is a concrete path that cuts through the garden. The buildings that surround the garden offer little shade as the garden is constantly exposed to sunlight. Area 2 : Garden Temperature day 1 15 cm above ground: 28.8 degrees Temperature day 2 15 cm above ground: 29.3 degrees 1.5 m above ground: 29.0 degrees 1.5m above ground: 27.8 degrees

6. This open area is mostly made up of concrete. It is surrounded by trees and vegetation that provide some shade. Nearby buildings also shade the area. Area 3 : Open Space Behind Block C Temperature day 1 15 cm above ground: 30.0 degrees Temperature day 2 15 cm above ground: 28.2 degrees 1.5 m above ground: 30.5 degrees 1.5m above ground: 28.2 degrees

7. The terraces are a flight of stairs made of concrete. The top of the stairs have nearby trees that provide shade. The bottom area is open and windy. Area 4 : Terraces Temperature day 1 15 cm above ground: 29.6 degrees Temperature day 2 15 cm above ground: 28.0 degrees 1.5 m above ground: 29.3 degrees 1.5m above ground: 27.6 degrees

8. The field is a patch of land that is covered in grass. It is out in the open and has no objects to shade it, it is also very windy. Area 5 : Field Temperature day 1 15 cm above ground: 34.0 degrees Temperature day 2 15 cm above ground: 28.8 degrees 1.5 m above ground: 32.3 degrees 1.5m above ground: 28.2 degrees

9. The running track is made of rubber. It is out in the open and there are no objects to shade it from the sun and thus it is very sunny and windy there. Area 6 : Running Track Temperature day 1 15 cm above ground: 32.7 degrees Temperature day 2 15 cm above ground: 29.0 degrees 1.5 m above ground: 31.5 degrees 1.5m above ground: 28.8 degrees

10. The fountain is surrounded by concrete paths. There are many surrounding buildings but they provide little shade from the sun. Area 7 : Fountain Area Temperature day 1 15 cm above ground: 32.7 degrees Temperature day 2 15 cm above ground: 28.2 degrees 1.5 m above ground: 31.5 degrees 1.5m above ground: 28.3 degrees

11. After collecting the data, we reviewed it and ranked the different parts of HCI from 1 to 7, with 1 being the coolest based on average. Ranking: Day 1 (16/1/14, 11.30am-12.30pm) Parts of HCIRanking Top floor of MSCP 7 Garden1 Space between Block C and canteen3 Terraces2 Field6 Running track4/5 Fountain4/5

12. Ranking: Day 2 (17/1/14, 10.30am-11.30am) Parts of HCIRanking Top floor of MSCP 2 Garden6 Space between Block C and canteen3 Terraces1 Field5 Running track7 Fountain4

13. test part Day 1: MSCP (justified: concrete surface, little shelter) Day 2: track (justified: little shelter) Summary

14. lest part Day 1: Garden (justified: plants around to keep area cooler) Day 2: Terraces (unjustified: concrete, little shelter at bottom) Summary

15. Our hypothesis therefore accepted as overall, places with concrete surfaces had a higher temperature than non-concreted areas. On Day 1, places with concrete grounds such as the MSCP, they were generally hotter than the other places. However, this could also be because the readings were taken at slightly different times. This also resulted in a rather big difference of temperatures at the MSCP However, our hypothesis can also be rejected as on the second day, the terraces, which has concrete grounds, had generally lower temperatures compared to the other places. Therefore, we need to take into consideration of more of other factors that affect our results. Conclusion
