What is Estidama Pearl?

Definition

Estidama Pearl is the Pearl Rating System, Abu Dhabi's sustainability rating framework for buildings, villas and communities under the Estidama program. Projects earn from one to five Pearls for design and construction performance across water, energy, materials, livability and integrated development.

What it is

Estidama, meaning sustainability in Arabic, is Abu Dhabi's program for sustainable development. The Pearl Rating System applies it to individual projects, with separate versions for buildings, villas and communities.

A minimum rating of one Pearl is required for new developments in Abu Dhabi, and government funded buildings are required to achieve a higher level. Credits reward reduced water demand, energy efficiency, metering and monitoring, and other measures. Check the current program rules for requirements that apply to your project.

Who it applies to / where it is used

Pearl ratings apply to new buildings and communities in the Emirate of Abu Dhabi. Developers, architects, MEP engineers and Pearl Qualified Professionals use the framework during design and construction. Owners use the same water and energy measures in operation.

How it is measured / what evidence it needs

Ratings are assessed through design and construction submissions. Operational data shows whether the building performs as designed.

  • Design stage water and energy calculations
  • Metering and monitoring provisions specified in the design
  • Construction stage evidence of installed systems
  • Measured water and energy use after occupancy

How Aqueduct helps

Aqueduct supplies metered water and energy evidence for operational performance and for credits that depend on metering and monitoring.

  • Sub-metered water balance through aQ WaterGuard, so demand reductions are measured
  • Energy and cooling baselines through aQ EnergySmart
  • Indoor air monitoring through aQ AirSafe for livability measures
  • Specified-in metering and controls with MEP teams at design stage
Questions

Estidama Pearl: common questions

It is Abu Dhabi's sustainability rating framework for buildings, villas and communities. Projects earn one to five Pearls.

Yes, new developments must achieve at least one Pearl, and government funded buildings must achieve a higher level. Check current rules for your project.

Yes. Water conservation is a major category, rewarding reduced demand, efficient fixtures, reuse and metering.

Aqueduct supplies measured water and energy data and works with MEP teams to specify metering at design. The project team and assessors handle the rating.
