Scope is the first question in any UAE indoor air quality assessment, and it is answered differently by each instrument. Dubai Municipality's technical guidelines divide buildings by age, applying one clause to new buildings and another to existing ones, and exclude an entire class of premises from their reach. Al Sa'fat divides buildings by function, imposing testing on a defined list of existing building categories while separately setting mandatory requirements for all new buildings. Abu Dhabi takes neither approach: its Codes of Practice are mandatory to all entities regardless of risk classification, so the duty follows the workplace rather than the building type, while the Estidama Pearl Rating System attaches to the project at permit stage. An owner establishing which route applies has to run each of these tests independently, because a building can fall inside one instrument and outside another at the same time.
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, separate its treatment of buildings by age.
Clause 9-8-3 addresses new buildings and states that buildings which optionally apply the procedures will be awarded an indoor air quality certificate by Dubai Municipality. Scope under this clause is therefore self-selected: a new building enters the route by choosing to apply the procedures, and the Table 1 limits become the entry conditions for the certificate. Table 1 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 as the short-term value.
Clause 9-8-4 addresses existing buildings. It contains no optional qualifier and states that indoor air testing for the contaminants in Table 2 must be carried out. Scope under this clause is not self-selected. Table 2 sets TVOC at 0.6 mg/m3 over 8 hours, 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.
The Dubai guideline's scope excludes premises exclusively dedicated to industrial and medical sectors, for example hospitals and factories. The exclusion is expressed in terms of exclusive dedication, which means the relevant question is what the premises are dedicated to rather than what activities happen incidentally within them.
Notably, healthcare facilities appear as a listed category under Al Sa'fat clause 401.07 even though hospitals are given as an example of the premises excluded from the Dubai Municipality guideline. The two instruments define their scope independently of one another, and a building must be tested against each definition separately rather than being assigned to a single regime.
Al Sa'fat, the Dubai Green Building System, 2nd edition January 2023, reaches existing buildings through clause 401.07, which requires listed categories of existing building to apply testing. The listed categories are hotels, shopping malls, educational facilities, government buildings, healthcare facilities, mosques and worship buildings, theatres and cinemas.
For those categories the clause sets formaldehyde below 0.08 ppm as an 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. Retesting is required within 5 years of the last compliant test, an interval that belongs to Al Sa'fat alone.
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.
Separately from clause 401.07, Dubai Municipality states that Al Sa'fat includes a set of mandatory requirements for all new buildings to obtain the Silver Sa'fa, with Golden and Platinum optional for higher performance. Scope for new buildings under Al Sa'fat is therefore universal rather than category-based, and Silver is the mandatory tier.
Al Sa'fat clause 401.01 requires the latest edition of ASHRAE Standards 62.1, 62.2 and 170. Because the requirement is expressed as the latest edition, no edition year may be attached to it, and a specification that pins a particular year is not tracking the clause correctly.
Clause 401.02 requires return air filters of minimum MERV 8, a design and maintenance parameter that applies to the ventilation installation rather than to a measured air sample.
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 to them. They govern what may be specified and installed rather than what is measured in occupied air, and comparing a grams per litre product limit with a micrograms per cubic metre air value is a category error.
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, so scope is not narrowed by building category, building age or risk tier.
Indoor-environment and ventilation duties sit 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, so an owner searching for a standalone indoor air code will not find one and should read the amenities code instead.
The 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. Figures taken from it are published reference points rather than enforceable limits. 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.
Establishing scope in practice proceeds through a short sequence of independent questions. The first is jurisdiction, because the operative instruments differ between Dubai and Abu Dhabi. The second, in Dubai, is whether the building is new or existing, because that determines whether clause 9-8-3 or clause 9-8-4 of the Dubai Municipality guideline is in view. The third is whether the premises are exclusively dedicated to industrial or medical use, which removes them from the guideline's scope. The fourth is whether the building falls within one of the categories listed in Al Sa'fat clause 401.07.
In Abu Dhabi the sequence is shorter but wider. Because the Codes of Practice are mandatory to all entities regardless of risk classification, the duty under Code of Practice 8.0 attaches without a category test. Where the building is a project at design or construction stage, the Estidama Pearl Rating System applies in addition: Abu Dhabi City Municipality states 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 answers are cumulative rather than exclusive. A new hotel in Dubai can sit inside the Al Sa'fat mandatory requirements for new buildings, become subject to clause 401.07 testing once it is an existing building, and separately choose to enter the Dubai Municipality certificate route under clause 9-8-3. Substance-specific chemistry, biological contamination, HVAC hygiene and ambient air monitoring are addressed elsewhere and are outside the scope of this page.
Clause 9-8-3 applies to new buildings as a voluntary route; clause 9-8-4 requires testing of existing buildings.
Al Sa'fat clause 401.07 lists hotels, malls, educational, government and healthcare buildings, mosques, theatres and cinemas.
The Dubai guideline excludes premises exclusively dedicated to industrial and medical sectors.
ADOSH-SF Codes of Practice are mandatory to all entities in Abu Dhabi regardless of risk classification.
Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life, DM-HSD-GU119-IAQ Version 4 of 11 December 2024, apply a voluntary certification route to new buildings under clause 9-8-3 and a testing requirement to existing buildings under clause 9-8-4, and exclude premises exclusively dedicated to industrial and medical sectors. Al Sa'fat 2nd edition is mandatory at Silver level for all new buildings and imposes clause 401.07 testing on listed categories of existing building. ADOSH-SF Codes of Practice are mandatory to all entities in Abu Dhabi regardless of risk classification.
No. The scope of Dubai Municipality's Technical Guidelines for Indoor Air Quality for Healthy Life excludes premises exclusively dedicated to industrial and medical sectors, giving hospitals and factories as examples. The exclusion turns on exclusive dedication of the premises. It removes those premises from the guideline only; healthcare facilities appear separately as a listed category under Al Sa'fat clause 401.07, so a building excluded from one instrument may still be reached by another and each scope test must be applied independently.
Clause 401.07 of Al Sa'fat, 2nd edition January 2023, requires listed categories of existing building to apply testing: hotels, shopping malls, educational facilities, government buildings, healthcare facilities, mosques and worship buildings, theatres and cinemas. The clause sets 8-hour time-weighted average limits for formaldehyde, TVOC, carbon dioxide, carbon monoxide, ozone and respirable dust, together with bacteria and fungi each below 500 CFU per cubic metre as per-sample counts that are not time-weighted, and retesting within 5 years of the last compliant test.
No. Al Sa'fat 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. Those limits are expressed in grams per litre and govern product composition, so no averaging period applies and they cannot be compared with airborne concentration values such as the 300 micrograms per cubic metre 8-hour TVOC limit. They constrain what may be specified and installed rather than what is measured in the occupied air of a completed building.
