Sofia Airport Center (SAC) consists of 180,000 square 
meters (1.8-million square feet) of Class A office space 
and 
28,000 square meters (300,000 square-feet) of logistics 
and 
warehouse space, which is 100 percent occupied. 
Logistics 
facilities, which are located in three separate structures, 
offer office space and feature state-of-the-art security 
and 
safety systems. Future plans call for a high-quality, 175-
room hotel with recreational, dining and conference 
facilities, as well as additional logistics and office space.  
SAC is Bulgaria's first Leadership in Energy and 
Environmental Design (LEED) commercial development.
SAC incorporates environmentally friendly materials with 
state-of-the-art technologies to reduce operating costs as 
much as 30% and provide a comfortable, healthy 
environment for employees, which leads to a reduction 
in 
morbidity among them up to 35 %. Sustainable features 
include an energy-efficient VAV HVAC system, controlled 
by 
an automated building management system - BMS; 
advanced fiber optics; abundant natural light through 
open 
atriums and double-gazed windows; and solar shading 
on 
building exteriors to reduce heat and solar gain.
The site is an outdoor showcase, providing a 5,000-
square-
meter park environment of lush landscaping and winter 
gardens with water features and outdoor seating, as well 
as 
open recreational space, which includes walking trails 
and a 
central lake.
