Sustainability at St. Margaret's
St. Margaret’s Episcopal Church has received EarthCraft Light Commercial certification for St. Margaret’s Callahan Center, a 6,600 square foot building completed in 2013. The Callahan Center is used for administrative purposes, church meeting rooms and the St. Margaret’s Community Outreach program offices. The Callahan Center replaced the Gable House, a structure which previously housed the administrative offices and Outreach program. This certification is among only three religious campus projects in the state of Georgia that have utilized the Earthcraft program.
EarthCraft Light Commercial (ECLC) is a regional green building certification program offering third-‐party recognition for environmentally responsible design and construction practices for small-‐scale, or “light,” commercial buildings in the Southeast. The program focuses on site planning, energy and water efficiency, building durability and improved occupant health and productivity.
The Church’s Building Committee, Vestry and Architect worked diligently so that the site used for the Callahan Center was carefully planned within St. Margaret’s existing campus. Priorities were to minimize the amount of trees that had to be cut down, reuse of some of the previous administrative building materials in the new construction, and assure the new building’s concrete, drywall and exterior cladding all contain recycled materials. Spray foam insulation was used along the building roof plane to create a thermal barrier as well as an air barrier, which contributes to the building energy efficiency, as well as its good indoor air quality. Water saving fixtures, ENERGY STAR appliances, lighting controls and thermal performing windows also contribute the structure’s energy and water efficiency.
