The Edge Office Building

399 Edgewood Avenue, Atlanta

Atlanta-based architecture and green building consulting firm The Epsten Group used the Athena EcoCalculator to pursue the LEED LCA pilot credit and validate the environmental benefits of renovation versus new construction at their new office near the Martin Luther King Jr. Historic District.

Year: Completed 2011

LEED rating: LEED Platinum

Architect: The Epsten Group, Inc.

Built in 1946, the 2,800 square foot structure at 399 Edgewood Avenue in Atlanta’s Martin Luther King Jr. Historic District was in a dilapidated state in 2009 when the decision was made to renovate and add on to it. Now one of the greenest buildings in the State, the 9,000 square foot office building is occupied by The Epsten Group, an architecture and high performance building consulting firm, and Dynamic Dish, a vegetarian eatery. This adaptive reuse of a 1940’s building reflects the owner’s commitment to sustainability on all levels, and incorporates several technologies that both conserve natural resources and enhance the daily lives of its occupants.


The project team for The Edge Office Building had to consider the impact of retaining or replacing several existing building components, including the roof deck and joists, the second floor assembly, and exterior walls. The Athena EcoCalculator helped the team weigh their options using a metric based on environmental impact, not just immediate cost.

Project leader Dagmar Epsten explains:  “The EcoCalculator helped us quickly conceptualize the environmental impacts of our design decisions in renovating an existing building. The EcoCalculator is a pioneering leap into the standardization of Life Cycle Assessments and we were happy to participate in USGBC’s LEED Pilot Credit for Innovation in Design for LCA using it.”
