Cooling System Design for Abdullah bin Khalifa Stadium: Evaluating Performance with Energy Modeling

The Flowpak Consultant Expert completed a project for a stadium located in Qatar. The project’s main objective was to design the HVAC system of the stadium, which would provide cool air to the outdoor seating areas and the pitch and also support feedback on the performance of the thermal comfort parameters and energy use of the HVAC systems.

Key assumptions were made with regard to the model settings, including construction materials, occupied hours, system pre-conditioning and post-conditioning times, and the type of HVAC system used.

The stadium was assumed to be occupied for 6 hours, from 18:00 to 24:00 hrs, with a pre-conditioning period of 1 hour and a post-conditioning period of 30 minutes. The stadium would be operational from 17:00 hrs to 00:30 hrs, and fresh air handling units (FAHUs) would provide tempered fresh air for seating and pitch areas during this time period.

The Macroflo model was used to calculate bulk air movement and simulate airflow through openings in the modelled spaces. Macroflo was invoked as an adjunct to the Dynamic Simulation engine ApacheSim, and the Macroflo openings were assigned to the adjacencies between the stadium and the external environment.

In conclusion, the Flowpak Consultant Expert successfully carried out the HVAC design for the stadium in Qatar, taking into account all necessary considerations and assumptions.

The assessment was successfully conducted through the Integrated Employment Services (IES).

“Dynamic Thermal Simulation of The Seero Fi Al Ardh Carousel: A Comprehensive Assessment of Thermal Comfort and Energy Consumption”

Flowpak performed a dynamic thermal simulation on the design of The Seero Fi Al Ardh Carousel, a circular pavilion building with a 46m diameter and 12m height, consisting of a glazed façade and multiple roof systems.

The simulation aimed to evaluate the building’s thermal comfort and energy consumption.

Flowpak was commissioned by Zublin Strabag and used Virtual Environment (IES-VE) for the simulation.

District cooling served as the primary cooling source, with additional cooling from Individual Comfort Thermal Units. Flowpak’s detailed representation of the building’s performance satisfied Zublin Strabag.
