Thornton Tomasetti's building sustainability practice assists clients in identifying opportunities to integrate successful green solutions into the design, construction and operation of buildings. As a leading provider of high-performance green building services, we are recognized for our extensive experience worldwide. In January 2012, Thornton Tomasetti acquired the green building consulting firm, Fore Solutions. This acquisition enabled Thornton Tomasetti to grow its sustainability services into a practice area.
