This professional project focused on improving the thermal performance and reducing the overall energy consumption of an office building dedicated to electricity distribution in Dubai, UAE.
Considering Dubai’s extremely hot climate and the high dependency of commercial buildings on mechanical cooling systems, the primary objective was to implement passive design strategies capable of minimizing cooling loads, improving energy efficiency, and enhancing environmental sustainability.
The project was conducted by Rymast Studio under the supervision of Dr. Amirhossein Janzadeh, acting as the Energy Performance Consultant.
The core objectives of the project included:
At the initial stage, the entire building was recreated as a detailed 3D energy model using DesignBuilder simulation software.
All relevant parameters were accurately integrated into the model, including;
Following the modeling phase, comprehensive simulations were conducted to compare the virtual model’s thermal behavior against realistic operational benchmarks, ensuring simulation accuracy and reliability.
One of the first stages of the parametric analysis involved identifying the optimal building orientation relative to solar exposure and climatic conditions.
After extensive simulations, the optimal azimuth angle was determined as; 170 Degrees
This orientation provided the best thermal performance and minimized solar heat gain throughout the year.
Following orientation optimization, the project focused on improving the thermal performance of the building envelope.
Several modifications were applied to;
Simulation results demonstrated that improving envelope materials reduced annual energy consumption from; 2.54 GWh → 2.49 GWh. representing approximately; 2% Energy Reduction solely through material optimization.
The next phase investigated advanced passive strategies, including;
Natural ventilation was activated under the following conditions;
This strategy significantly reduced dependence on mechanical cooling systems.
The smart shading system was programmed to operate whenever indoor temperatures exceeded 24°C.
The automated louvers dynamically shaded window surfaces to;
The integration of;
resulted in a substantial reduction in building energy consumption.
Annual energy demand decreased to; 2.36 GWh, which presents: 27.1% Reduction in Energy Consumption compared to the baseline model.
The project successfully achieved:
Replicable passive strategies for Middle Eastern climates
