Don Ferrier, CGB (Certified Green Builder), is the Owner and CEO of Ferrier Companies. As the third generation of Scottish immigrants who were stone masons and builders, he founded his business in 1984 in response to an increased need for high-performance construction methods addressing energy efficiency. Ferrier was one of the first builders in Texas to use structural insulated panels (SIPs) which provide high energy efficiency, superior strength, fire-resistance and sound insulating properties beyond typical stud construction. Additionally, SIPs combine pre-cut components and expedited assembly, positively impacting business operations due to time and cost savings. Ferrier has also advanced sustainable building best practices through expertise in site development, earth-sheltered construction, water conservation and net-zero technologies. In response to customer needs, the initial company split in 2004 designating Ferrier Custom Homes to address the residential market and Ferrier Builders to focus on commercial and remodeling services. The Ferrier mission is characterized by a family-owned and operated entrepreneurial business model, evidence-based performance research for green building technologies, award-winning projects and prototypes for new materials and methods, public education through on-site tours and case studies, increased rigor for green building credentials, and alliances with local, regional and national industry partners. Don Ferrier continues to advocate for green building as a speaker, teacher, and advisor to local, regional, national and international audiences.
