Energy modeling in KSA has become an essential technical and strategic discipline as Saudi Arabia accelerates its sustainability agenda under Vision 2030. As the Kingdom continues to develop large-scale commercial, residential, and mixed-use projects, decision-makers increasingly rely on accurate energy models to guide design, investment, and compliance strategies.
However, energy modeling in Saudi Arabia differs fundamentally from modeling practices used in temperate or mixed climates. Due to extreme environmental conditions, long cooling seasons, and unique operational behaviors, generic assumptions often produce misleading results. Therefore, climate files, cooling dominance, and realistic setpoints must form the foundation of any credible energy model in the Saudi context.
This article explains how energy modeling in KSA should be approached, why regional specificity matters, and how accurate assumptions directly influence performance outcomes, certification success, and operational efficiency.
Climate Files as the Foundation of Energy Modeling in KSA
Why Accurate Climate Data Matters
First and foremost, every energy model begins with climate data. In energy modeling in KSA, the selection of climate files plays a decisive role in determining simulation accuracy. Saudi Arabia experiences extreme outdoor temperatures, intense solar radiation, and prolonged cooling periods that differ significantly from global averages.
Consequently, using generic Middle East weather files or outdated Typical Meteorological Year (TMY) data often leads to underestimated cooling loads and unrealistic energy predictions. Instead, project teams must rely on city-specific, validated climate files that accurately represent local hourly conditions.
Moreover, climatic variations across the Kingdom are substantial. For example, Riyadh’s dry desert climate differs notably from Jeddah’s coastal humidity profile. As a result, a single national climate assumption cannot represent all Saudi projects reliably.
For internationally accepted guidance on weather data selection, organizations such as ASHRAE provide recognized standards and methodologies.

Cooling Dominance: The Core Reality of Energy Modeling in KSA
Cooling Loads Drive Energy Consumption
Unlike colder regions where heating and cooling loads balance seasonally, energy modeling in KSA operates within an almost entirely cooling-dominated paradigm. In most Saudi buildings, cooling accounts for 60–75% of annual energy consumption, making it the single most influential factor in energy performance.
Therefore, models must explicitly reflect this reality. Overemphasizing heating loads or applying balanced seasonal assumptions leads to distorted outcomes and unreliable benchmarks.
In practice, cooling dominance affects:
-
HVAC system sizing and efficiency assumptions
-
Envelope performance sensitivity
-
Solar heat gain and glazing strategies
-
Peak electrical demand predictions
Furthermore, cooling systems often operate for extended hours, particularly in commercial, hospitality, healthcare, and mixed-use developments. As a result, energy models must accurately represent operational schedules rather than relying on simplified or international defaults.
Realistic Setpoints: Closing the Gap Between Models and Reality
Why Setpoints Matter More Than Assumed
One of the most common weaknesses in energy modeling in KSA is the use of unrealistic cooling setpoints. Although international guidelines often assume cooling setpoints of 24–25°C, actual operational practices in Saudi Arabia frequently target 20–22°C for occupant comfort.
Consequently, models that rely on higher setpoints significantly underestimate cooling energy demand. This discrepancy affects not only predicted energy use but also financial analyses, system sizing, and return-on-investment calculations.
To illustrate:
-
Lower setpoints increase cooling loads disproportionately
-
Extended operating hours amplify annual consumption
-
Equipment efficiencies appear overstated if assumptions are unrealistic
Therefore, credible energy modeling in KSA must align setpoints with local comfort expectations, not theoretical benchmarks. While regulatory compliance may require standardized assumptions, sensitivity analyses can help bridge the gap between compliance and operational reality.
Regulatory Context for Energy Modeling in Saudi Arabia
Aligning Models with National Requirements
Saudi Arabia continues to strengthen its building energy framework through initiatives such as the Saudi Building Code (SBC) and national energy efficiency programs. As a result, energy modeling increasingly supports regulatory compliance, performance benchmarking, and government approvals.
In many large-scale developments, authorities require energy models to demonstrate:
-
Justified climate file selection
-
Transparent modeling assumptions
-
Realistic HVAC system representation
-
Compliance with national efficiency targets
The Saudi Energy Efficiency Center (SEEC) plays a key role in shaping these requirements and promoting best practices nationwide.

Therefore, energy modeling in KSA must not only be technically sound but also well-documented and defensible during reviews and audits.
Energy Modeling for Green Building Certifications in KSA
Supporting LEED and International Rating Systems
International certification systems, particularly LEED, are widely adopted across Saudi Arabia for commercial and institutional projects. Within these frameworks, energy modeling in KSA directly influences certification levels, cost optimization strategies, and sustainability credibility.
However, while LEED provides a global structure, it does not automatically account for Saudi-specific operational realities. Consequently, consultants must ensure that models reflect regional climate behavior, cooling dominance, and realistic usage patterns.
At ERKE Consultancy, energy modeling is integrated into a broader sustainability strategy that aligns certification goals with real-world performance. This approach supports both compliance and long-term operational value.

Best Practices for Accurate Energy Modeling in KSA
Key Principles for Reliable Outcomes
To achieve meaningful results, energy modeling in KSA should follow several best practices:
-
Use city-specific, validated climate files
-
Explicitly model cooling-dominated energy profiles
-
Apply realistic cooling setpoints and schedules
-
Align HVAC efficiencies with locally available systems
-
Document all assumptions clearly and transparently
In addition, sensitivity analyses provide valuable insights. By testing different setpoints or operational scenarios, stakeholders can better understand how comfort preferences influence long-term energy consumption and costs.
Energy Modeling as a Strategic Tool for Vision 2030
From Compliance to Value Creation
Beyond regulatory requirements, energy modeling in KSA serves as a strategic decision-support tool. Under Vision 2030, Saudi Arabia aims to reduce energy intensity, improve building efficiency, and lower operational carbon emissions.
Accurate energy models enable project teams to:
-
Compare design alternatives objectively
-
Prioritize investments with measurable impact
-
Reduce operational risks
-
Support long-term sustainability targets
Therefore, when performed correctly, energy modeling transforms climate challenges into opportunities for innovation and optimization.
Frequently Asked Questions (FAQ)
