1. Microclimate Fieldwork @ HCI Andrew Ke Bryan Ng Nguyen Vu Khang Zhang Chen

2. Hypothesis  As the wind speed increases, the temperature drops

3. Items used  An all-in-one instrument that can measure things like temperature, wind speed, humidity and air pressure.  Within that, we used:  Anemometer  To measure the wind speed  Thermometer  To measure the temperature

4. Procedure Summary  We would be going to strategic locations across the Hwa Chong Campus on the 29 th January and the 4 th February from around 11am to 12am to find out how the wind speed can affect the temperature

5. Locations  Top floor of Multi-storey Car park  Open air fire hydrant  Garden outside the printing centre  At the tree stump  Open space between the canteen and Block C  At the centre of the semicircle  Terraces  On the ninth step  Field  At the flag pole  Running Track  At the starting point  Fountain area outside General Office  At the corner of the fountain nearest to LT3

6. Procedure  Get to the specific location  Make sure that this is the exact same location for both days

7. Procedure (Wind)  Use the anemometer to measure the wind speed  Anemometer must be in front of the user and the user must face the wind  Anemometer should be slightly higher than the user, to make sure that no wind is obstructed

8. Procedure (Temperature)  Use the thermometer to measure the surrounding temperature  Let the reading stabilize before taking it  Make sure the height at which the temperature is taken remains constant, because heat from the ground might interfere with the results.

9. Results (Day 1)

10. Results (Day 2) Temperature/ °C Wind Speed/ m/s

11. Evaluation  Is the hypothesis true?  Yes, since we can see a trend that as the wind speed increases, the temperature decreases  Unusual Data?  There are lots of unusual readings we had, but these are probably caused by our lack of much precaution and of proper equipment  The unusual reading might have also been caused by the varying weather conditions such as presence of cloud cover

12. Problems Faced  Difficult to get a constant reading because of fluctuating wind speeds and temperatures due to varying intensity of sunlight  The instruments used to collect the data was not very reliable and restarted often

13. Learning Points  The higher the wind speed, the lower the temperature of an area  The intensity of sunlight and proximity to nearby buildings also affects the temperature  The temperature nearer the ground is hotter because there is more heat radiating form the ground

14. Questions  Does humidity affect the temperature of an area?  Is wind nearer the ground stronger or wind higher in the air?

15. Bibliography  All data taken from the authors
