A regulation that changes the maximum U-value on an external wall sounds like a technical footnote until a design team discovers, mid-permitting, that their submitted drawings no longer clear the threshold. Al Sa’fat — Dubai Municipality’s green building rating system — makes Silver-tier compliance the mandatory minimum for building permits, and the envelope limits that follow from it shape massing and glazing decisions long before submission.
One point of terminology first, because it causes real confusion. “Al Sa’fat 2.0” is not a 2026 release. Dubai Municipality published a document titled “Dubai Green Building System Version 2.0” in 2020, and the currently applicable text is the 2nd Edition of January 2023. Consultancy material circulating in 2026 conflates the two labels and attaches new procedural claims to them. Where such claims are not traceable to Dubai Municipality, they should be verified before being built into a submission programme.
The legal basis and who must comply
Al Sa’fat — Arabic for palm fronds, reflecting the leaf-based rating symbols — is Dubai Municipality’s green building system, distinct from Abu Dhabi’s Estidama Pearl Rating System and not interchangeable with it.
Mandatory compliance was formalised by Administrative Resolution No. (154) of 2020, which approved the Bylaw on the Dubai Green Building System. The Resolution states plainly that satisfaction of the Silver Sa’fa standards is mandatory for all Buildings in the Emirate, while Gold and Platinum are optional.
Al Sa’fat sits alongside the Dubai Building Code, launched in January 2022, which unifies prescriptive and performance-based design requirements. The DBC sets minimum performance standards; Al Sa’fat supplies the certification and rating hierarchy on top of them.
The tiers — and why “four” is now misleading
Al Sa’fat is widely described as a four-tier system running Bronze, Silver, Gold, Platinum. That reflects an earlier version of the framework. Administrative Resolution No. (154) of 2020 sets out three classifications — Silver, Gold and Platinum — and in the Version 2.0 tables, Gold requirements are expressed as additional to Silver rather than to Bronze.
| Tier | Status | Indicative energy saving |
|---|---|---|
| Silver Sa’fa | Mandatory for all buildings in the Emirate | Up to 19% |
| Gold Sa’fa | Optional | Around 32% against the baseline criteria |
| Platinum Sa’fa | Optional | Exceeding 35% |
Those savings figures, attributed to Dubai Municipality, are the practical reason some developers pursue Gold or Platinum even though Silver is all the permit requires: the operating-cost differential is material over a holding period, and the certification carries weight in green-financing terms and with institutional tenants.
Gold and Platinum certificates are valid for five years.
Exemptions the guides usually omit
Mandatory does not mean universal, and the exceptions matter to anyone working on an atypical asset. Under Administrative Resolution No. (154) of 2020, exemptions may apply to heritage buildings, special-purpose structures, and projects that achieve equivalent or greater sustainability benefits by other means.
Separately, the Resolution provides that certain Silver Sa’fa standards, conditions and requirements may be optional for private villas. A villa project assuming the full commercial Silver burden may be over-specifying; one assuming blanket exemption is exposed.
There is also a design-level relief worth knowing early: where a green roof covers 30% of the building’s total surface area, the project is exempted from certain insulation requirements. That is a trade-off available at concept stage and largely unavailable afterwards.
Envelope and energy: the numbers that shape the design
The core of compliance sits in energy-and-envelope performance: a modelled improvement over a recognised baseline reference building, maximum U-values for walls, roofs and glazing, a ceiling on solar heat gain coefficient, and a cap on window-to-wall ratio for most typologies.
The prevailing Dubai figures, as cited in technical literature analysing the regulation:
| Element | Limit |
|---|---|
| External walls | 0.57 W/m²K |
| Roofs | 0.30 W/m²K |
| Glazing (U-value) | approximately 1.9–2.0 W/m²K |
| Glazing SHGC | 0.28 for a glazed area of 40–60% |
Two cautions on this table. The SHGC ceiling is banded by glazed area, not a single figure — secondary summaries that quote one number without the corresponding window-to-wall band are simplifying something that materially affects a façade design. And chiller COP requirements vary by equipment type, starting from around 2.8, rather than sitting at a single value.
These are the figures to confirm directly in Dubai Municipality’s current Al Sa’fat document before schematic design, because they constrain massing and glazing at a point where correction is cheap and constrain them expensively later.
Water efficiency
Al Sa’fat sets fixture-level requirements — maximum flow rates for taps and showers, efficient dual-flush specifications for toilets — applied at specification stage rather than left to product selection at fit-out. Grey-water and treated sewage effluent use inside a building triggers a separate set of mandatory requirements under the system’s water articles.
Fit-out: scaling the burden
Not every fit-out carries the same compliance load. Al Sa’fat scales by scope: major fit-outs affecting a large share of floor area or involving structural change are treated much like a new-build submission; smaller non-structural work follows a lighter path; purely cosmetic work with no MEP change carries the lightest requirement.
Thresholds separating these categories are set by Dubai Municipality. A commonly cited dividing line places non-structural commercial fit-outs below a share of built-up area on a simplified checklist rather than a full energy model — but the specific percentage should be confirmed against current Municipality guidance rather than taken from consultancy summaries, and a project near a boundary should have its classification confirmed before assuming the lighter path.
Submission and documentation
Compliance is documented through a sustainability submission accompanying the permit application, which typically includes the project’s energy model rather than a narrative summary of expected performance. A working documentation set generally comprises:
- The energy model with its baseline comparison, demonstrated quantitatively
- U-value calculation sheets for each external element
- SHGC calculation and window-to-wall ratio compliance
- Water efficiency fixture schedule with manufacturer data sheets
- Low-VOC materials schedule with product certifications
Dubai Municipality continues to strengthen materials-related documentation, encouraging developers to substantiate the sustainability credentials of specified materials from design stage rather than treating it as a procurement afterthought. Portals, formats and checklists change; current Municipality guidance is authoritative at the point of submission.
Frequently asked questions
Does Al Sa’fat apply in Abu Dhabi? No. Abu Dhabi runs the Estidama Pearl Rating System, with a minimum of one Pearl for building permits and an entirely different credit structure. Confusing the two emirates’ systems is among the most common and costly errors for developers operating across both markets.
Can a project pursue LEED or BREEAM instead? No. Both run in parallel as optional international certifications, typically for investor-facing credibility, but neither substitutes for mandatory Al Sa’fat compliance in Dubai.
Which tier does a standard new building need? Silver. Gold and Platinum are optional under Administrative Resolution No. (154) of 2020 and are pursued for sustainability credentials, operating-cost savings and financing terms rather than to satisfy the permit.
Is my villa exempt? Not automatically. The Resolution allows certain Silver requirements to be optional for private villas, which is narrower than a blanket exemption. Confirm the specific position for the project.
Conclusions
Al Sa’fat converts green-building expectations in Dubai into an auditable permit condition rather than aspirational guidance: Silver mandatory for all buildings under Administrative Resolution No. (154) of 2020, optional Gold and Platinum delivering roughly 32% and above 35% energy savings against around 19% at Silver, and specific envelope, glazing and fixture limits in the system’s technical tables.
Three practical points follow. Read the current thresholds from Dubai Municipality’s own document, not from summaries — the SHGC ceiling in particular is banded by glazed area and is routinely quoted as a single figure. Check the exemption route early, because heritage status, special-purpose classification, the private-villa provision and the 30% green-roof relief all change the brief. And build the envelope limits into the design brief before schematic design, since the glazing and massing decisions they govern cannot be corrected cheaply at permit stage.
Information purposes only — not technical, financial or regulatory advice. Al Sa’fat thresholds are set by Dubai Municipality and revised periodically; figures above are drawn from the Municipality’s published system, Administrative Resolution No. (154) of 2020 and technical literature analysing the regulation, and should be confirmed against the current official document before use. Procedural claims circulating in consultancy material about a 2026 release could not be verified against primary sources.
