LOTUS CERTIFICATION SYSTEM

LOTUS is a set of voluntary green building rating systems developed by Vietnam Green Building Council (VGBC). In Vietnam, VGBC has registered the Vietnam Green Building Social Enterprise Co. Ltd. to manage the LOTUS assessment and training programs. 

Developed based on established building physics science and adapted to the conditions, climate, and regulations of the Vietnam construction sector, LOTUS provides a holistic assessment of environmental performance over the life cycle of buildings. It provides an integrated approach for evaluating buildings in terms of energy consumption, water use and waste management as well as indoor environmental quality. It serves as an objective rating system that can be used by any stakeholder in the construction process – developers, designers, contractors and owners alike – for decision-making purposes.

Since the first LOTUS pilot program was released in 2010, the rating system has undergone several updates and revisions. The latest version is LOTUS New Construction (NC) v3, released in April 2019. LOTUS now cover almost all building types and project scopes, including:

• LOTUS NC v3, for new construction projects with a gross floor area (GFA) of 2,500 m2 or more (both residential and non-residential buildings)
• LOTUS BIO, for projects in operation
• LOTUS Homes, for single housing projects
• LOTUS SB, for small-scale non-residential projects (GFA less than 2500 m2)
• LOTUS Interiors, for interior finishing projects
• LOTUS Small Interiors, for small-scale interior finishing projects (area under 1000 m2)
