Director of Engineering
Super Stud Building Products

Don Allen, P.E., LEED A.P., is an internationally known expert on cold-formed steel (CFS) design. Allen has given presentations about CFS on four continents, and received the CFSEI Distinguished Service award. As Director of Engineering for Super Stud Building Products, Allen is involved with hundreds of CFS projects each year. Allen spent 9 years serving concurrently as Technical Director for SSMA, the Steel Framing Alliance, and the CFSEI. Allen is a member of American Society of Civil Engineers (ASCE) SEI Committee on Sustainability, the ASCE SEI Committee on Cold-Formed Steel, and chairs the Education Committee of the AISI.

Assessing Cold-Formed Steel Enclosures versus Alternative Enclosures

Across the United States the operation of buildings account for nearly a third of the total energy use and greenhouse gas emissions each year. Over the life of a building, the total energy used is a combination of the embodied energy in the building materials and the operating energy of the building. Building enclosures (walls and roofs) have an enormous impact on both embodied energy and operating energy. Historically, steel has been a material with a high embodied energy, which has led to numerous misconceptions that steel enclosures use significantly more energy than other enclosure types. This presentation assesses the research and methodology of cold-formed steel enclosures compared to other enclosure types in commercial buildings. This presentation highlights the advantages of cold-formed steel enclosures and their competitiveness when compared to other enclosure systems. This presentation highlights a roadmap for AEC professionals seeking more sustainability responsible building practice.


  1. Understand the relationship between Embodied Energy & Operating Energy in various building Types
  2. Evaluate the environmental burdens of a building throughout its life and techniques to account for these burdens
  3. Assess various wall and roof enclosure systems and their performance
  4. Apply Green Building concepts to help improve sustainability factors and thermal controls
