From Maitiú Ward’s “Lilli Apartments” on Australian Design Review:

Despite the challenges of working mainly within the tight constraints of high-rise residential development, it is Elenberg Fraser’s stated ambition to introduce one new environmental feature into every building it designs.

As Fraser describes it, to date Lilli is the most successful exploration of the wind-model driven, passive systems approach it has been developing. While aesthetically striking, the distinctive scalloped striations of Lilli’s balconies have actually been carefully designed to draw air into the apartment interiors.

Working with engineering company VIPAC from data on site-specific solar and wind patterns, the facade elements have been modelled to not only provide sunshading, but also emphasise pressure differentials between the balconies off the living rooms and windows in the bedrooms.

In effect, rather than cross ventilation, what this creates is ‘through’ ventilation, as wind is trained across the facade and then sucked laterally through the apartment interior, in one opening and out the other.

Leaving the window to the surprisingly deep balcony open a crack, Fraser pops the casement window in the main bedroom, and sure enough, from my spot in the centre of the living room I feel a distinct breeze begin to play across my skin. It seems like such a small thing – a gentle eddy so subtle that many occupants may not even notice it; enough, perhaps, to keep them just those few degrees shy of reaching for the air conditioner remote – but it has wide implications.
