Wind velocity vector and contour horizontally across the Ground Floor of the building ( Z-X plane )
Wind velocity vector and contour horizontally across Level 8 of the building ( Z-X plane )
The wind profile across the Ground Floor level of the building shows the rows ' definition of location . Wind velocity vector and contour horizontally across Level 8 of the building Z-X plane .
Wind velocity vector and contour horizontally across Level 4 of the building ( Z-X plane )
Wind velocity vector and contour horizontally across Level 12 of the building ( Z-X plane )
The wind profile at Level 4 and 12 for Case 2 exhibited similar scenarios to Case 1 . However , when the angle of a wind attack was modelled at 45 ° to the building , the initial wind direction passed through to row 1 and 4 at the left section of the building floor and later travelled outward to the void . Comparatively , low airflow velocity passed through rows 2 and 3 at the right section of the floor .
Case Study Results and Findings
From the observation of the two cases , it can be concluded that in Case 1 , row 1 of the building floor , which faces the wind , offers better ventilation than rows 2 , 3 , and 4 . This is because a crosswind flow occurs at row 1 and 4 of the building floor , and speed has been reduced when the crosswind is flowing through row 2 and 3 . Therefore , wind acting at 90 0 ( perpendicular ) to the building wall , as per Case 1 will produce good ventilation , which means that each housing unit facing the wind will gain an adequate natural ventilation of airflow . However , as per Case 2 ,
wind acting at 45 0 measured from the edge of the building wall is the best orientation for the headwind .
An accurate orientation strategy before the construction site determination is needed , is to maximise the surface exposure to the prevailing wind . A sufficient opening with a 6m height at the Ground Level and the middle of the building floor ( Level 8 ) enables the wind to pass through the ground space and the garden of DeLIGHT Homes . The opening will create a refreshment space due to the high prevailing wind . Inside the DeLIGHT Homes building , the spatial void ( 33.367m long × 19.202m wide × 53.540m high ) will produce stack
