4. Conclusion The project design highly benefits from maximizing sun shading in East and West, and optimizing sun shading in North and South. Light-colored external shading devices may provide slight comfort in warm and humid periods. The curved form allows harsh winds of up to 15 m/s to flow smoothly along the façade minimizing the sway. Although the structural system allows for design freedom in terms of a column free floorplate, the overall efficiency of 65% is not a viable scenario for an office building. This can be increased by reducing the height of the tower to allow for a different structural system. Furthermore, PET’s sky lobbies at multiple levels helps in connecting occupants to greenery and trees. Incorporating these, the tower supplies more nature-friendly environments. Vertical foliage would also help cool the tower down by reducing the heat island effect. In terms of skyline implications, the PET is observed to be holding a central location when viewed from 2 vantage points. V3 suggests that PET will break the monotony and harmony observed from the other two. The use of clay orange materiality in the solar shading devices reflected in the South Façade does not cause visual disruption or awkwardness in the skyline. Tall structures can be sustainable; the main impediments are economic and societal, but not technological, as depicted in this report. However, geography plays a key role, as Indonesia has surplus geothermal energy available at shallow depths than the rest of the world. Geothermal energy generation is proposed to produce surplus energy than the campus's energy demand, feeding electric power from renewable sources back into the grid, thus making the project netpositive on energy. Capital costs for renewable energy sources and market acceptance are economic constraints, while visual effect, novelty, and safety are societal concerns.
