Engineers own the credits
Every credit gets an owner and an evidence route at the start. Review comments are answered by the engineer who ran the study, not by a coordinator reading it for the first time.
LEED & green building
LEED and green building
Hit your LEED and Mostadam targets with no surprises. Credits engineered into the design, evidence ready before the reviewer asks, and every comment answered by the engineer who ran the study.
Your green rating starts in the design, not in the paperwork.
Who this is for Contractors handed a green scope, developers choosing a rating, and design teams that want the credits secured early.
Price this scopeWhat you receive
The right rating, chosen with numbers
LEED v5, Mostadam or both. You see the achievable level, the cost premium and the programme impact before you commit a riyal.
Credits built into the design
Credit requirements written into the architectural, structural and MEP design and into the specification while changes still cost little.
Energy points you can see
Whole-building baseline and proposed models to ASHRAE 90.1 Appendix G that show where the energy points are, with every input listed for the reviewer.
Daylight, comfort and carbon studies
Daylight and glare, thermal comfort, PV yield and whole-building life-cycle assessment, each issued as a clear report a reviewer can check.
Credits protected on site
Submittals checked against credit requirements, EPD and recycled-content evidence collected, waste diversion tracked and IAQ plans run, so the points survive construction.
Submission handled to the final ruling
Credit forms, narratives and calculations submitted on Arc, GBCI's platform for LEED v5, with every reviewer comment answered by the engineer who ran the analysis.

How it is produced
01
Evidence designed in from day one
Every credit gets an owner and an evidence route at kickoff, so nothing turns out to be unprovable at submission.
02
One model, one building
The energy model is exported from the BIM model, not redrawn, so the simulation and the drawings always describe the same building.
03
No hidden assumptions
Occupancy, schedules, setpoints and weather file are stated in every report, so a reviewer never has to ask what was assumed.
04
The engineer who modelled it answers for it
Review comments go to the engineer who ran the study, not to a coordinator reading it for the first time. Faster answers, fewer rounds.
The proof points behind every LEED proposal.

Three reasons the evidence holds up at review.
The model is the evidence
Energy models, daylight studies, quantities and schedules come out of the coordinated BIM model, so the simulation and the drawings describe the same building.
Designed in, not chased
Credit requirements are written into the design and the specification while they are still cheap, so nothing is discovered to be unprovable at submission.
One team for design, fit-out and operations, under LEED and Mostadam.
USGBC keeps LEED v4 and v4.1 registration open until 30 June 2027. We test your project against v4.1 and v5 before you register, so the version is a decision and not a default.

Five steps from the first scorecard to the final review.
01
Feasibility & gap analysis
Rating system, version and target level tested against your design, with the cost premium and programme impact of each route.
02
Registration & credit plan
Project registered, scorecard fixed, and every credit given an owner, an evidence route and a date in the programme.
03
Integrated design & simulation
Credits written into the drawings and the specification. Energy, daylight and LCA models run from the BIM model.
04
Construction tracking
Submittals reviewed against credit requirements. Waste diversion, IAQ plans and commissioning evidence tracked monthly.
05
Submission & review
Forms, narratives and calculations submitted on Arc, GBCI's platform for LEED v5, and every reviewer comment answered through to the final ruling.
Evidence is designed in, not chased afterwards. Two-stage quality control on every submission: discipline check, then independent senior review.
One coordinated model feeds the simulations, the quantities and the evidence.
-
01 · The model
- Coordinated Revit / IFC model: architecture, structure and MEP federated and clash-checked
- LEED parameters on elements (material, SRI, VOC class, flow rates)
- areas, zones and occupancy from rooms and spaces
- ISO 19650 workflow with the LEED data drops named in the BEP
-
02 · What we extract
- Energy-model geometry exported through gbXML / IDF, not redrawn
- daylight and views (sDA / ASE) run on the model geometry
- material quantities by element for LCA, recycled content and waste baselines
- fixture, lighting, equipment and material schedules behind the credit calculators
-
03 · What LEED receives
- Evidence a reviewer can trace: credit calculators filled from model schedules
- energy, daylight and comfort simulation reports
- whole-building LCA from model quantities
- an evidence register with one row per credit (owner, document, status)
- forms and narratives ready for Arc

How we run an energy model: traceable from the locked input to the engine output.
Dynamic, hourly, whole-building models that stand up to a reviewer: for LEED, Mostadam, SBC 601 and investment decisions.
01
Inputs & assumptions register
Weather file, schedules, setpoints, loads and tariffs are issued for your review, then confirmed and locked before any simulation runs.
02
Geometry from the BIM model
Zones, envelope and areas are exported from the coordinated model, so the simulation and the drawings describe the same building.
03
Baseline and proposed runs
Identical models that differ only in the measure under study, so every saving is attributable to that measure.
04
A report a reviewer can follow
Assumptions stated, results traceable, and review comments answered by the engineer who ran the study.
Nothing in the report has to be taken on trust.
- Gate 1 Inputs locked in a client-confirmed register before the first run
- Gate 2 Models validated against the engine schema with zero errors
- Gate 3 Runs accepted only when they complete with zero severe errors
- Gate 4 Independent analytical cross-check of the dynamic result
- Gate 5 Every reported figure re-extracted from the output database by script
Standards, studies and the engines behind them.

LEED certifies buildings, not products.
There is no LEED certificate for a paint, a panel or a chiller. A project’s LEED consultant accepts evidence that your product contributes to specific credits. We build that evidence file to the standard a GBCI reviewer expects, in both languages.
LEED credit contribution statement
Credit by credit, which requirements your product meets under LEED v4, v4.1 and v5, with the supporting documents indexed.
Test data and gap review
SRI to ASTM E1980, VOC content and emissions, recycled content and origin: what you hold, what is missing, and which laboratory test closes the gap.
EPD / HPD roadmap
Programme operator, PCR, LCA scope, budget and timeline to a published EPD or HPD, so the product scores under the BPDO credits.
Performance evidence by simulation
Independent EnergyPlus studies that quantify what the product does to cooling load, surface temperature, cost and CO₂ in a Saudi climate.
Lead consultant, sub-consultant or a single study: the scope fits the gap in your team.
Engagement
- Full LEED / Mostadam certification management Feasibility to final review, for owners and developers.
- Sub-consultant to the lead designer We carry the analysis and the documentation, working to your templates.
- Credits protected on site The green clauses your contract flows down to you: submittals, tracking and evidence.
- Standalone studies Energy model, daylight, thermal comfort, LCA or commissioning support (Cx / EBCx).
- Manufacturer & supplier documentation LEED credit contribution files, EPD roadmaps and performance studies.
What is not in our fee
- Registration and review fees of the certification body, billed at cost
- An independent commissioning authority, where the rating requires one
- Site testing and measurement: blower door, IAQ sampling, flush-out
- A guaranteed certification outcome. The review belongs to the certification body.
Stated up front, so offers can be compared like for like.

Questions clients ask
Should we go for LEED or Mostadam?
It depends on who is asking for it. Saudi government clients and master developers usually specify Mostadam; international tenants and lenders usually want LEED. Our feasibility study prices both, and one evidence set can serve both ratings.
What LEED work have you delivered?
LEED BD+C and O+M work for owners such as the Ministry of Environment, Water and Agriculture, the ZHI Headquarters scorecard we tracked to 80 of 110 points, and comparative energy studies such as the cool-wall coating study. Each project page shows the scope we carried.
How late can we start and still certify?
The earlier the better, because design-phase credits close as the design closes. Starting after tender usually costs points rather than money, and our gap analysis tells you exactly which ones are still within reach.
Do you work as a subconsultant to the lead design team?
Yes, and it is our most common arrangement. We carry the analysis and the documentation and work to the lead consultant's templates, so your team keeps the client relationship.
A question that is not here?
Ask the engineer who would run your project. Send the drawings and the answer comes back in writing.
