ASCENSION Pioneering Capital-Centric Architecture with Environmental Harmony Banking University of HCMC Site A Ascension embodies a pioneering approach where economic strides precede environmental considerations, strategically positioned in Vietnam’s financial district. The architectural design, a testament to simplicity and efficiency, intricately balances capital demands with a commitment to reducing carbon impact. The three-block massing, innovative facades, and integrated green elements define a visually striking yet economically focused hotel. This project marks a decisive ascent toward a future where architecture seamlessly merges economic growth and environmental consciousness, emphasizing a direct capitalcentric yet sustainable ethos.

Transformation by doing more with less Banking University of HCMC Site A Situated in the heart of HCMC District 1’s business hub, we recognised the potential of this school building. Most of the building is kept to preserve its original value, save for a some renovations and additions. This office building strives to provide quality working spaces that impact the natural environment in a positive way - reducing embodied carbon and operational carbon without sacrificing the comfort of its users. Our project aims to achieve as high of a carbon efficiency as possible. With built infrastructure contributing 40% of our carbon emissions, architects have a huge responsibility to innovate and reduce our carbon impact.
