Li Fung Centre is the regional headquarters of Li Fung Group and has been renovated from an existing building first built as a printing press.
The building features a large, open office area with high ceilings inherited from the previous industrial function. Other additions built over the years have been converted into spaces for office use and for lobby, dining, and auditorium functions. The building is located in an urban area in Istanbul in a densely developed region with plenty of public transportation opportunities.
The renovation work was carried out in 2010, and the building has been awarded LEED Silver certification for its sustainable features.
The designers retained all the structural elements and exterior building envelope during renovation.
Three interior courtyards in the large, open office area let in plenty of daylight for office employees, while automated shading louvers above these courtyards adjust their positions for optimum passive solar use in winter and for preventing excessive heat gain in summer. All exterior windows are fitted with exterior and interior manual shading devices.
With high ceilings and no use of false ceilings in almost all spaces, daylighting is maximized. The high number of operable windows both on the perimeter and on the interior courtyards provide natural ventilation possibilities in mild temperatures, while heat-recovery-ventilation units provide efficient mechanical ventilation.
An existing chiller and boiler plant have been retained from the previous building ownners, but has been supplemented with a VRF system due to capacity problems. The VRF units serve areas that are occupied intermittently, while the two pipe fan coil units serve all office areas.
The building features local automation of lighting and terminal HVAC units with motion control sensors in most spaces. Interior lighting is overwhelmingly CFL units, while all exterior parking area lighting is provided by full cut-off LED luminaires.
The building features an 18 kW thin-film photovoltaic system.
