Wide to Narrow The lower level receives lesser light therefore windows closer to the streets are wider to maximize light and becomes narrower to the top to minimize glare

Glare Control External plants: each of the windows on the northern facade has a balcony with trellised planting on each side. Internal plants: moveable internal planters on each side of most windows on the south elevation

Active lighting system – Building Management System (BMS) Timber Louvres The west facing façade is covered with a system of timber louvres that pivot to optimize the penetration of natural light protect the façade from the harsh western sun.
