Energy efficiency was a significant by-condition in the design work of the New Block (23, 700 m2; 255, 100 ft2) of the University Hospital in the city of Linkoping in Sweden. The block is made up of several interconnecting buildings of between two to four floors, and contains the Heart Centre, the Ear Centre and the Clinic for Infectious Diseases. The principal aim of the design work was to decrease the electrical energy end-uses for air distribution, cooling and lighting (electronic ballasts, occupancy sensors).
CFD (Computational Fluid Dynamics) modelling of particle transport has been applied for the control of airborne particles in the operating zone above the surgery table in an operating room. Based on the numerical results, it has been found that the particle source location, air (supply) inlet design, operating table location, and lamp design are among the critical parameters responsible for the particle distribution within the operating room.
