Building Description: The Whitaker Building is a mixed-use, historic renovation project located in the heart of downtown Savannah. This project is the first LEED-Certified building in Savannah, receiving a Silver certification from the U.S. Green Building Council in Winter 2004. The challenge of balancing the historical integrity of the building with the sustainable practices in LEED resulted in a wonderful historic renovation that is 40 percent more energy and water efficient than a comparable new building built to code.

Overview

The first renovation of a building on the National Registry of Historic Places in the Southeast to receive LEED certification, this circa 1891 structure is now a fully leased building that combines technology and heritage.

The tax credits, 100 percent occupancy with long-term leases, reduced operating costs and competitive rate of return all translate into economic success for Melaver, but the developer uses a three-prong approach to evaluate its bottom line—balancing economic, environmental and social considerations.

Balancing History and the Future

During construction, historic preservation standards required by the Department of Interior were sometimes at odds with LEED standards. For example, historic guidelines required windows to look like their original design, which posed a challenge to energy efficiency. The design team located an energy-efficient pane that preserved the original appearance while offering 72 percent less ultraviolet light transmittance. Creative approaches like this allowed the building to meet Silver LEED certification and earn the Georgia Trust for Historic Preservation’s 2004 award for Excellence in Rehabilitation.
