Meydan Building Q

Meydan Building Q is the third building in the N–P–Q cluster ISG is delivering simultaneously within the Meydan precinct. Like its neighbours, Building Q is in the Design & Construction phase and pursuing LEED ID+C certification, with ISG engaged as Green Building Management and LEED consultant. Where N and P emphasise portfolio coordination and the energy modelling pipeline, Building Q is a useful frame for the indoor environmental quality side of LEED — the credits that determine how the building actually feels to occupy.

Indoor Environmental Quality — the credit category that occupants actually notice

The Indoor Environmental Quality (IEQ) category in LEED is, in the building's day-to-day operation, the most directly experienced. Energy savings and water efficiency matter on the utility bill. IEQ matters every time someone walks in the door. The category covers ventilation rates above the ASHRAE baseline, low-VOC interior materials, daylight access for occupied spaces, views to the outdoors, thermal comfort within the ASHRAE 55 envelope, and acoustic performance.

For Building Q, the IEQ-relevant scope includes:

• Daylighting simulation — modelling spatial daylight autonomy across regularly occupied spaces, balanced against the solar-heat-gain risks of large glazed openings in Dubai's climate.
• Acoustic consultancy — sound transmission between spaces, background noise levels (NC/RC criteria), and reverberation control. Dubai's preference for hard, reflective interior surfaces (stone, glass, polished concrete) tends to push acoustic ratings down unless explicitly designed for.
• Low-emitting materials — VOC limits on paints, adhesives, sealants, flooring, and ceiling/wall systems, demonstrated through manufacturer certifications.
• Construction IAQ Management — ducted-system protection during construction, flush-out before occupancy, and verification testing.

Why IEQ has rising weight in the rating system

LEED has evolved towards occupant outcomes over time. The original LEED rated mostly inputs — credits for installing a low-flow tap, specifying a low-VOC paint, building near transit. Newer versions, including LEED v4.1 and the upcoming LEED v5, pay increasing attention to verified outcomes: actual indoor air quality, actual thermal comfort, actual daylight performance. That trend is also reflected in the WELL Building Standard, which is health-and-wellbeing first and which ISG also delivers (most prominently on the Mubadala Investment Company offices).

For a Meydan building marketed to leasing tenants, the IEQ story is the part of the LEED scorecard that translates most directly into commercial value: better daylight and acoustics support higher-quality tenant experience, which supports rental rates and renewal.

Coordinated delivery across N, P, Q

ISG's engagement on the three Meydan buildings is structured to share strategy across the cluster. Across Building N, Building P, and Building Q, the LEED interpretations, performance baselines, contractor procedures, and reporting templates are aligned — which is what allows three concurrent submissions to USGBC without each one becoming a bespoke negotiation.
