ADD Inc. and Elaine Construction Co. hosted 150 guests at an event celebrating the seventh anniversary of greenGoat, a Boston-based non-profit that boosts building efficiency through conservation measures. The event was held at 311 Summer St., ADD Inc.'s new LEED headquarters in the Fort Point Channel area. The evening toasted greenGoat's efforts to parlay their existing success in the corporate realm. Both ADD and Elaine Construction have worked on projects using greenGoat's approach to asset management, the cornerstone of greenGoat's service offering. Through this approach, building materials are tracked as assets to the company as a way of planning in advance for the strategic distribution of materials.
