Dubai and Abu Dhabi approach indoor air quality from opposite directions. Dubai has issued detailed technical documents that name contaminants, set numerical limits with explicit averaging periods and, in one clause, offer a certificate in return for compliance. Abu Dhabi has issued a mandatory occupational safety framework in which indoor-environment duties are embedded in a general workplace amenities code without a dedicated indoor air instrument, alongside a green building rating system that reaches indoor air at permit stage. The difference is not merely stylistic: it changes who is obliged to act, what a compliant outcome looks like, which body verifies it and what documentation results. This page compares the two routes clause by clause, keeping each numerical value attached to the instrument, table and averaging period that produced it.
In Dubai the operative documents are Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, reference DM-HSD-GU119-IAQ, Version 4, issued 11 December 2024 by its Health and Safety Department, and Al Sa'fat, the Dubai Green Building System, 2nd edition January 2023. The guideline contains a split character. Clause 9-8-3 states that new buildings which optionally apply the procedures will be awarded an indoor air quality certificate by Dubai Municipality, making that clause a voluntary certification route. Clause 9-8-4 carries no optional qualifier and states that indoor air testing for the contaminants in Table 2 must be carried out for existing buildings.
Al Sa'fat supplies the mandatory element for new construction in Dubai. Dubai Municipality states that from 19 October 2020 Al Sa'fat replaced the Dubai Green Building Regulations and Specifications, and that it includes a set of mandatory requirements for all new buildings to obtain the Silver Sa'fa, with Golden and Platinum optional for higher performance. Silver, not Bronze, is the mandatory tier.
In Abu Dhabi the competent authority is the Abu Dhabi Public Health Centre and the framework is ADOSH-SF. Its Codes of Practice are mandatory to all entities regardless of risk classification. There is no voluntary certificate analogue: the duty attaches by default, and it attaches to entities rather than to self-selecting buildings.
Dubai's requirement is written in an instrument whose subject is indoor air quality. That makes the contaminant list, the thresholds and the averaging periods explicit and locatable in named tables and clauses.
Abu Dhabi's requirement is written inside Code of Practice 8.0 General Workplace Amenities, Version 4.0 of 15 July 2024, at section 3.7 on HVAC. There is no Abu Dhabi Code of Practice dedicated to indoor air quality. An owner or consultant looking for an Abu Dhabi indoor air code will find the duty only by reading the amenities code, which is a structural difference with practical consequences for how compliance documentation is assembled.
The Abu Dhabi Public Health Centre's separate Occupational Standards and Guideline Values document is recorded by the Centre as suspended, with entities directed to comply with relevant local or federal standards in force. Any figure sourced from that document is a published reference point rather than an enforceable limit, and presenting one as an Abu Dhabi threshold misstates the position.
Code of Practice 8.0 section 3.1.1(b) cites MOHRE Administrative Decision No. 19 of 2023, issued in implementation of Federal Law No. 33 of 2021, as part of the chain of authority behind the Code.
Dubai Municipality Table 1, for new buildings under clause 9-8-3, sets TVOC at 300 micrograms per cubic metre over 8 hours and formaldehyde at 0.01 ppm over 8 hours long-term with 0.08 ppm equal to 0.1 mg/m3 over 30 minutes short-term.
Dubai Municipality Table 2, for existing buildings under clause 9-8-4, sets TVOC at 0.6 mg/m3 over 8 hours, twice as lenient as the Table 1 value, formaldehyde identical to Table 1, carbon dioxide at 800 ppm over 8 hours, carbon monoxide at 9 ppm over 8 hours and ozone at 0.06 ppm over 8 hours.
Al Sa'fat clause 401.07, for listed categories of existing building, sets formaldehyde below 0.08 ppm 8-hour time-weighted average, TVOC below 300 micrograms per cubic metre 8-hour time-weighted average, carbon dioxide below 800 ppm 8-hour time-weighted average, carbon monoxide below 9 ppm 8-hour time-weighted average, ozone below 0.06 ppm 8-hour time-weighted average, respirable dust below 150 micrograms per cubic metre 8-hour time-weighted average, and bacteria and fungi each below 500 CFU per cubic metre as per-sample counts that are not time-weighted.
The same number appears under both instruments on different bases. Dubai Municipality's eight-hour formaldehyde value is 0.01 ppm, and its 0.08 ppm figure is a thirty-minute short-term value. Al Sa'fat separately and correctly applies 0.08 ppm as an eight-hour time-weighted average. It is therefore incorrect to attribute 0.08 ppm over eight hours to Dubai Municipality.
Abu Dhabi publishes no equivalent table of enforceable indoor air concentration limits, because the duty sits in a general amenities code and the standards and guideline values document is suspended. A direct numerical comparison between the two emirates is therefore not available, and any table purporting to show one should be treated with caution.
Under the Dubai Municipality guideline, testing must be by a company or laboratory accredited by EIAC, the Emirates International Accreditation Centre. Accreditation is a threshold condition rather than a preference, and results produced outside it do not support the certificate route.
Al Sa'fat clause 401.01 requires the latest edition of ASHRAE Standards 62.1, 62.2 and 170, with no edition year attached. Clause 401.02 requires return air filters of minimum MERV 8. Clauses 404.01 and 404.02 require VOC content limits set by Dubai Municipality, certified by Dubai Central Laboratory, landing on standard DMS 0020:2016; these are grams per litre limits on product composition, not airborne concentrations, so no averaging period applies.
In Abu Dhabi, verification runs through the entity's own compliance with mandatory Codes of Practice and, for projects, through the Estidama route. Pearl Qualified Professionals prepare and submit Estidama compliance applications. The Department of Municipalities and Transport governs the system's policies, and Abu Dhabi City Municipality's Sustainable Buildings Section implements it during the design and construction phases.
Al Sa'fat and Estidama both bring indoor air quality inside a broader sustainability assessment, but they operate differently. Al Sa'fat sets a mandatory Silver tier for all new buildings in Dubai and, through clause 401.07, imposes testing with named limits on listed categories of existing building, including a retesting interval of within 5 years of the last compliant test. That interval is an Al Sa'fat interval only and does not attach to any other instrument.
Abu Dhabi City Municipality states that the Estidama Pearl Rating System is a tiered evaluation system ranging from one to five pearls, that government-funded projects must achieve a minimum two-pearl rating while privately funded projects must achieve at least a one-pearl rating, and that meeting these requirements is essential for obtaining a building permit. The system has mandatory and optional credits, and indoor air quality sits within its indoor and outdoor livability credit category.
The outcome of the Dubai clause 9-8-3 route is an indoor air quality certificate awarded by Dubai Municipality. No validity period or retest interval is published for that certificate, so no expiry date should be stated for it, and any renewal cycle asserted in a management plan is not drawn from the guideline.
The outcome of clause 9-8-4 is a completed test against Table 2 for an existing building, without a certificate attached to the clause. The outcome under Al Sa'fat clause 401.07 is a compliant test result that starts the 5-year retesting clock.
In Abu Dhabi the outcome is evidence of compliance with mandatory Codes of Practice, and for projects a pearl rating relevant to the building permit. Substance chemistry, biological contamination, HVAC hygiene and ambient air monitoring fall outside this comparison and are addressed elsewhere.
Dubai combines a voluntary certificate route with a testing requirement; Abu Dhabi's Codes of Practice bind all entities.
Dubai has a dedicated indoor air guideline; Abu Dhabi places the duty in Code of Practice 8.0, section 3.7 on HVAC.
Dubai publishes Tables 1 and 2 with averaging periods; Abu Dhabi's guideline values document is recorded as suspended.
Dubai requires EIAC-accredited testing; Estidama applications are submitted by Pearl Qualified Professionals.
In Dubai, DM-HSD-GU119-IAQ Version 4 of 11 December 2024 operates clause 9-8-3 as a voluntary certification route for new buildings and clause 9-8-4 as a testing requirement for existing buildings, and Al Sa'fat 2nd edition is mandatory at Silver level for all new buildings. In Abu Dhabi, ADOSH-SF Codes of Practice administered by the Abu Dhabi Public Health Centre are mandatory to all entities regardless of risk classification, with indoor-environment duties inside Code of Practice 8.0 Version 4.0 of 15 July 2024, section 3.7.
The question cannot be answered numerically. Dubai publishes explicit limits in Tables 1 and 2 of DM-HSD-GU119-IAQ Version 4 and in Al Sa'fat clause 401.07, each with a stated averaging period. Abu Dhabi publishes no equivalent enforceable table, because indoor-environment duties sit inside Code of Practice 8.0 General Workplace Amenities and the Abu Dhabi Public Health Centre records its separate Occupational Standards and Guideline Values document as suspended. The comparison is one of legal structure rather than of threshold severity.
It depends on the instrument. Al Sa'fat clause 401.07 applies formaldehyde below 0.08 ppm as an 8-hour time-weighted average. Dubai Municipality's 8-hour formaldehyde value in both Table 1 and Table 2 is 0.01 ppm, and its 0.08 ppm figure, equal to 0.1 mg/m3, is a 30-minute short-term value. Attributing 0.08 ppm over eight hours to Dubai Municipality is incorrect, and every quoted concentration should carry both its averaging period and its source clause.
No certificate equivalent to the Dubai Municipality route is described in the Abu Dhabi framework. The Abu Dhabi Public Health Centre administers ADOSH-SF, whose Codes of Practice are mandatory to all entities regardless of risk classification, with indoor-environment and ventilation duties inside Code of Practice 8.0 General Workplace Amenities, Version 4.0 of 15 July 2024, section 3.7 on HVAC. For projects, the Estidama Pearl Rating System produces a pearl rating relevant to obtaining a building permit rather than an indoor air certificate.
