As one of Central America’s largest healthcare facilities, Vitta Center houses more than 200 medical clinics, a 100-bed hospital, office space, staff residences, and nearly 1,500 parking spaces. The three towers, clad in a combination of curtain wall and storefront systems, rise from a multistory podium. SGH performed daylighting and analyzed solar heat gain to help the architect design the exterior shading projections for the four major facades.

Scope | Solutions

SGH analyzed how the placement of exterior shading devices, including continuous horizontal overhangs and a randomized pattern of vertical fin shades, affect daylighting and solar heat gain. Using an automated simulation process, we evaluated hundreds of shading arrangements considering cost and physical constraints. For each arrangement, we quantified the conflicting parameters of daylight penetration into the space and solar heat gain on the glass for the architect to consider in combination with aesthetics.

Highlights of our work include the following:

  • Developed a three-dimensional model of the towers with plaza massing geometry; optical characteristics of the glazing and opaque materials; and properties of interior walls, floors, and ceilings

  • Evaluated the sun path over a typical year to predict shading by adjacent buildings and determine where facade shading devices would be most effective on the Vitta Center towers

  • Developed a matrix of our results for the architect to use in selecting the location, type, and size of shading device, allowing them to develop a design meeting both performance and aesthetic project goals
