WHAT IS LOTUS?

LOTUS is a set of voluntary market-based green building rating systems developed by the VGBC specifically for the Vietnamese built environment.

LOTUS rating systems are based on various international green building rating systems (LEED, Green Star, BREEAM, GBI Green Mark, etc.) and have the following goals to:

  • Establish standards and benchmarks specific to Vietnam
  • Guide the local construction industry towards efficient use of natural resources
  • Introduce and promote environmentally friendly practices

 

LOTUS RATING SYSTEMS

The LOTUS Certification System has been developed to consider all types of construction projects and different LOTUS Rating Systems have been created to adequately assess different types of project.

Currently, the set of LOTUS Rating Systems include the 7 following systems:

LOTUS MULTI-FAMILY RESIDENTIAL

LOTUS BUILDINGS IN OPERATION 

LOTUS INTERIORS

LOTUS SMALL BUILDINGS

LOTUS HOMES

LOTUS SMALL INTERIORS

WHAT ARE THE DIFFERENCES BETWEEN THE LOTUS RATING SYSTEMS ?

All LOTUS Rating Systems have a holistic approach with categories and credits taking into account:

  • the efficient use of resources
  • the impacts on the environment
  • the environmental indoor quality

However, each LOTUS Rating System has a specific scope of applicability based on the project type and size, and a project may only follow the LOTUS Rating System which is appropriate.

Standard vs. Streamlined

Also, the LOTUS Rating Systems could be categorized in 2 categories: the Standard LOTUS Rating Systems and the Streamlined LOTUS Rating Systems.

Standard LOTUS Rating Systems are the first systems that have been developed by VGBC (they include LOTUS NR, LOTUS BIO, LOTUS MFR and LOTUS Interiors). These systems have strict requirements with the aim to set the bar for the top of the construction market and to pull the rest of the market towards more sustainable practices.

Compliance with these systems can be challenging to achieve for small-scale projects (i.e. houses, buildings with less than 2,500 sqm, etc.) as a large number of requirements are too costly or inappropriate for such projects.

Streamlined LOTUS Rating Systems have been developed to propose a simplified, smaller version of LOTUS for these small-scale projects. The Streamlined LOTUS Rating Systems maintain a holistic approach but a number of differences in the certification process and the requirements for compliance (highlighted in table below) makes certification at an appropriate level of difficulty.

The scope and eligibility criteria set in the Standard LOTUS Rating Systems and the Streamlined LOTUS Rating Systems are clearly distinct. No project can decide to follow a Streamlined LOTUS Rating System instead of a Standard LOTUS Rating Systems to achieve LOTUS Certification more easily.

WHAT ARE THE LOTUS CERTIFICATION LEVELS ?

LOTUS Certification consists of four levels of certification – Certified, Silver, Gold and Platinum – based on the number of points a project is awarded. There is a varying number of points available for each rating system (including bonus points within the Innovation category).
To earn LOTUS Certification, a project must satisfy all prerequisites and achieve a minimum of 40% of the total amount of points.
 

 

LOTUS CATEGORIES 

LOTUS NR & MFR have 10 categories (including innovation) while LOTUS BIO has 9 categories which assess buildings according to an allocated weighting. The categories have been developed in line with green building principles of being energy and water efficient, environmentally and occupant friendly whilst reducing waste and pollution. Each category contains a varying number of credits. Against each credit, specific criteria have been set carrying individual scoring points. In addition, many categories have prerequisites which are mandatory and must be achieved in order to obtain LOTUS Certification.
