in big box retail buildings: In 1970, there were an estimated five
square feet of retail space for each person in the U.S. By
2000,that figure had risen to 20 square feet per capita. Since the
large retail (greater than 10,000 square feet) segment is the
second greatest energy user of all commercial segments, the
implications of this growth trend are significant. Moreover, the
U.S. Energy Information Administration (EIA) sees future retail
energy use outpacing new retail square footage. Compared to 2000
data, the EIA estimates that retail energy consumption will
increase by a factor of 17.2 percent by 2010 (even accounting for
increased equipment efficiency), while retail square footage will
increase by 15.8 percent (resulting in 23 square feet per
The design community can offset this imbalance by integrating
innovative but mainstream design principles and features into large
retail projects-and deliver enhanced productivity and sales at the
same time. For this reason, eNews brings you the results of an
extensive building simulation study for a large retail chain store,
and offers the challenges and lessons learned for maximizing energy
use in big box building design.
