  • office spaces
  • retail spaces (supermarkets, shops, etc.) and restaurants
  • hotels and hospitality spaces (spaces dedicated to businesses within the service industry that provide transitional or short-term lodging)
  • educational facilities
  • health facilities including clinics, etc.
  • dwelling-units in apartment buildings
To be eligible for LOTUS Small Interiors, projects must meet 6 Eligibility Rules which are detailed in the Technical Manual and the User Tool.

LOTUS Interiors certification or LOTUS SI certification?

LOTUS SI has been designed for small-scale projects.

Any project meeting one of the 2 following requirements can be considered as a small-scale project and can follow LOTUS SI instead of LOTUS Interiors:

1. The project has a gross floor area lower than 1,000 sqm

2. The project fit-out activities include no more than 2 of the following categories:

  • Installation of artificial lighting fixtures (not considering task lighting),
  • Installation of water fixtures or water appliances (not considering water dispensers)
  • Installation of HVAC systems (not considering the installation of split-units or minor works on HVAC systems such as moving air grilles, changing ducting, etc.),
  • Installation of commercial refrigeration systems such as walk-in refrigerators, walk-in freezers or refrigerated casework,
  • Installation of partitions, floorings and/or ceilings


Development of LOTUS SI

LOTUS Small Interiors V1 has been released in August 2017. It has been developed based on LOTUS Interiors as well as the 2 other streamlined LOTUS rating systems: LOTUS Homes and LOTUS Small Buildings.

Streamlined LOTUS Rating Systems have been developed to propose a simplified, smaller version of LOTUS for 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 makes certification at an appropriate level of difficulty.
