King Saud Bin Abdulaziz University for Health Sciences

King Saud Bin Abdulaziz

Integral Group is working with the National Guard Health Affairs (Saudi Arabia) and King Saud Bin Abdulaziz University (KSAU) to assist in the planning and design of three completely new health sciences universities in the cities of Riyadh, Jeddah, and Al Ahsa in Saudi Arabia. The University’s goal is to construct medical education facilities that will be rated among the top five medical education universities in the world. Combined, the academic and research buildings for the three campuses represent approximately 4 million square feet of built area.

In addition to the design efforts for the Jeddah campus, Integral Group also completed energy analysis comparisons for three of the Jeddah buildings: the Research Building (100,000 ft²), the Deanship Building (86,000 ft²), and the Administration building (140,000 ft²). Each of the energy models for the three (3) buildings compared the ASHRAE Standard 90.1 baseline against the proposed design for each building to establish its predicted annual energy performance. Energy models incorporated building envelope calculations, occupancy data and expected occupancy schedules, lighting and receptacle power densities, operating schedules, exterior lighting, lighting controls, and information on all utility rates, including electricity, gas, water, and plant chilled water. A minimum performance of LEED Gold is targeted for each of the buildings.


The mechanical, electrical and plumbing design was required to meet the intense climatic conditions of the three sites and to be highly sustainable and flexible for future research and teaching program changes. Sustainable strategies for the building systems include:

  • Energy recovery and/or evaporative cooling to pretreat ventilation air
  • Displacement air systems for large tiered lecture halls
  • Day lighting analysis and controls
  • Grey water flushing system
