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 NON-RESIDENTIAL

The first rating system developed by the VGBC. LOTUS NR assesses all types of non-residential buildings

LOTUS BUILDINGS IN OPERATION 

LOTUS BIO assesses any building that has been in operation for more than 18 months and has over 50% occupancy

LOTUS MULTI-FAMILY RESIDENTIAL

LOTUS MFR assesses residential buildings of more than 4 floors and with multiple separate dwelling units

LOTUS INTERIORS

LOTUS Interiors assesses all types of interior fit out projects

LOTUS SMALL BUILDINGS

LOTUS Small Buildings assesses all types of non-residential buildings that have a GFA lower than 2500 sqm

LOTUS HOMES

LOTUS Homes assesses single family dwellings (villas, terraced house or traditional rural house) 

LOTUS SMALL INTERIORS

For future development. LOTUS Small Interiors will assess interior fit out projects which are limited in size and/or in scope.

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.
