Criteria | GSAS | LEED |
Origin & Design | Middle East/GCC (2009) | USA (1998) |
Climate Calibration | Desert/arid climate optimized | Temperate climate biased |
Primary Market | Qatar, MENA, developing nations | Global (USA dominant) |
Qatar Status | MANDATORY for government & major projects | Voluntary |
Building Permit Requirement | Required in Qatar | Not required |
Energy Baseline | 320 kWh/m²/yr (Qatar-specific) | 250 kWh/m²/yr (USA-based) |
Weather Data Used | Doha TMY (actual Qatar climate) | ASHRAE 90.1 (USA zones) |
Water Focus | Water-scarce calibrated (critical) | Generic (assumes water abundance) |
Certification Levels | ★ to ★★★★★ (1 to 5 stars) | Certified → Silver → Gold → Platinum |
Number of Categories | 8 categories (UC, SI, EN, WA, IE, MA, WM, MG) | 7 credit categories |
Energy Category Weight | ~35% | ~30% |
Water Category Weight | ~15% | ~10% |
Approval Timeline | 4–8 weeks | 8–16 weeks |
Local Market Recognition | (Essential) | (Valued but optional) |
International Recognition | (Growing in MENA) | (Universal brand) |
GCC Investor Acceptance | (Standard) | (Acceptable) |
US Investor Acceptance | (Emerging) | (Preferred) |
Property Valuation Premium | +3–5% (growing) | +5–10% (established) |
Operating Cost Savings | 30% energy reduction typical | 25–30% energy reduction typical |
Cooling Load Accuracy | Realistic for Qatar (50°C heat) | Underestimates desert cooling |
Solar Radiation Baseline | 2,500 kWh/m²/yr (Qatar-accurate) | 1,500 kWh/m²/yr (USA average) |
Water Availability Assumption | Zero freshwater (100% desalination) | Water-abundant regions |
Best For Qatar Projects | Government, Ashghal, flagship | International investors only |
Best For Non-Qatar Projects | Emerging markets, MENA | USA, Canada, multinational |
Dual Certification Possible | YES (GSAS first, LEED second) | YES (incremental cost) |
Overlapping Credits | ~60% of credits overlap | ~60% of credits overlap |
Incremental Cost (if pursuing both) | Base cost | +USD 8K–20K additional |
Cultural Alignment | Designed for GCC context | Western-centric standards |
Risk of Non-Compliance | HIGH if Qatar project + LEED-only | No regulatory risk |
Recommendation for Qatar | MANDATORY | Optional add-on |
