Ventilation is our main cooling system for Domus. We therefore decided to test our design using fluid mapping, enabling us to see how the mound and courtyard affect the wind through the site. We had concerns that the mound may deflect the winds, reducing ventilation, and that turbulent swells may occur within the courtyard, thus making it uncomfortable to be in the space. Below are a fluid mapping snapshots, in plan and section
The fluid mapping test showed us that our design works really well with the main prevailing winds. The mound and the layout of the building on the site assist in the ventilation strategies of our design.We observed some swelling occurring in front of the Living Module with the cooler westerly winds. This suggests the wind is being blocked and is creating an uncomfortable space.
However, when we mapped the flow through the section we can see the winds pass quite easily under the floor and over the dam.
The above test (south0open) mapping the wind over the mound, shows the angle of the mound and position of the sleeping quarters is perfect for directing winds into the Living Quarters
The only area of concern is the swelling that occurs outside the Sleeping Quarters. This is due to the deep verandah eaves incorporated into our design for weather protection
