A Microclimate Study @HCI

1. AMicroclimate Study @HCI Group 4 Joel Tan(25) Chen Xinyang(5) Kai Wilson(16) Daniel(12)

2. Overview • Over a timespan of two lessons, we went through various locations through out the HCI compound • We took the readings of temperatures at these places, and at various heights above the ground.

3. Hypothesis • Areas with no natural vegetation/concrete are generally hotter than areas with natural vegetations. Hotter Cooler

4. First Day Comparison of weather conditions between both readings. The lesson was conducted during the early morning(8.30a.m.). It was generally windy and the sun was absent. Relative Humidity was low and there was more cloud cover.

5. Second Day Comparison of weather conditions between both readings The lesson was conducted in the early afternoon(1.00p.m.), hence the sun was directly overhead, making it very hot. There was little cloud cover and the relative humidity was high.

6. Concrete Areas Multi-StoreyCarpark

7. Concrete Areas Fountain area outside the general office

8. Concrete Areas Terraces

9. Concrete Areas Open Space Between Canteen And Block C

10. Non-Concrete Areas Garden Outside Printing Room

11. Non-Concrete Areas Field

12. Non-Concrete Areas Running Track

13. Area 1: MSCP • The multi-storey car park is directly under the sun. • It is not covered by any natural vegetation • It is made out of concrete. Average Temperature= 28.775° C

14. Area 2: Garden • The surface of the garden is grass. • There is a winding concrete path beside the garden. • Even though the garden is beside tall buildings, the buildings provide little shade. Average Temperature= 28.65° C

15. Area 3: Open Space Between Canteen and Block C • The surface of this area is made up mostly of concrete tiles. • The area is surrounded by tall buildings and trees, hence making it generally shady. Average Temperature= 28.525° C

16. Area 4: Terraces • The top few steps of the terraces is shaded by trees along the top of the terraces while the rest is unshaded. • The surface of the terraces is made out of concrete. • There is no natural vegetation growing on the steps. Average Temperature= 28.475° C

17. Area 5: Field • The field is an open, grassy area which is directly under the sun. • It is not near any buildings hence there is no shade. Average Temperature= 29.7° C

18. Area 6: Running Track • The running track is made out of rubber, a poor conductor of heat. • It is directly under the sun. • It is not near any buildings hence there is no shade. Average Temperature= 29.525° C

19. Area 7: Fountain • The fountain area outside the general office is made out of granite tiles. • There is a man-made pool of water. • It receives little shade even though it is near tall buildings. • It is directly under the sun. • There is no natural vegetation growing near the area. Average Temperature= 28.775° C

22. CONCRETE AREAS • MSCP • Open space

23. NON-CONCRETE AREAS • Garden outside printing centre • Fountain area • Terraces • Field • Running track

24. Comparing temperatures of concrete areas and non-concrete surfaces. Concrete Surfaces: Non-concrete Surfaces:

25. Conclusion… • Hypothesis: Areas with no natural vegetation /concrete are generally hotter than areas with natural vegetations. • Results: • Concrete Surfaces- 28.65° C • Non-concrete Surfaces-29.025° C (Higher) • Hypothesis is rejected/not reliable.
