An Analysis of Passive Design Strategy for Diamond Lotus Riverside High-Rise Apartment Project in Ho Chi Minh City

Sustainable development is the key goal that most of the current architectural trends, including green architecture, have been targeting. In order to achieve that goal, energy conservation in buildings is always the prioritised aspect to be considered carefully during the design process, especially in green buildings. Among many solutions for energy reduction, the passive design comes first and has been long-term effective during the building life cycle. Located in Ho Chi Minh City, Diamond Lotus Riverside is considered the first high-rise apartment of a Vietnamese investor that applied for both LEED and LOTUS green building certification at the gold level. The survey results show that this project has achieved LOTUS provisional certification and significant energy-saving indicators. This research focuses on the analysis of the passive design strategy that has been carried out in the Diamond Lotus Riverside project. From there, lessons can be drawn for designing energy-efficient high-rise apartment buildings in HCMC and Vietnam in general.
