NCPTT’s Architecture & Engineering program encourages research and partnerships with organizations and institutions working to advance preservation technology for buildings and other structures.

The NCPTT-supported Tarps New Orleans initiative protected dozens of historic homes ineligible for help from FEMA. The program demonstrates that high standards for methods, materials, safety and preservation can be achieved even in the face of widespread devastation.

The NCPTT-supported Tarps New Orleans initiative protected dozens of historic homes ineligible for help from FEMA. The program demonstrates that high standards for methods, materials, safety and preservation can be achieved even in the face of widespread devastation.

Architecture & Engineering’s goals are:

  • To transfer technologies and technical information among agencies and organizations, and between professional disciplines.
  • To disseminate research results towards increasing access to technology and expertise relevant to the built environment.
  • To provide on-site training programs aimed at scholars and professionals in practice.

Sustainable Approaches to Historic Preservation

The environmental impact of pollution on our built environment is one of NCPTT’s research priorities. Interpreting this broadly, Architecture and Engineering is focusing on sustainable practices that can greatly reduce the effects of the built environment on the natural world. Sustainable methods also address the preservation of threatened cultural landscapes, another of NCPTT’s research priorities. Through this initiative NCPTT aims to unite proponents of preservation and of the sustainable design movement. This discussion may lead to workshops and training seminars to help professionals find common ground between preservation and sustainable design.
