Associate Professor Russell Gentry is a structural engineer and building materials researcher.   His research focuses on technical performance aspects of building materials, components, and assemblies.  His work has considered mature building materials and systems, with ongoing projects in wood and concrete masonry, and on emerging building materials, with work in FRP (fiber reinforced polymers) and bio-based residues.   Dr.

Dr. Gentry pursues research that fall into three broad themes:

  1. Developing and assessing new load bearing materials and systems
  2. Embedding structural and fabrication logic into CAD and simulation tools
  3. Quantifying embodied and ongoing energy impacts of buildings – and use of these metrics in the design process

His current work in the materials area focuses on the development of high-modulus FRP reinforcements for use in strengthening juvenile pine laminated timbers.  His work in the structural systems area is focused on concrete masonry, jointly with Tristan Al-Haddad and Andres Cavieres.  He recently completed project (with Charlene Bayer of the Georgia Tech Research Institute and Michael Gamble) examining the future of Life Cycle Assessment in architectural practice.

Research Ambitions
My overall area of interest consists of defining and deploying evaluation protocols for technology innovations in the built environment. I intend to continue addressing relevant problems in the construction industry, such as the uncertainty of adopting innovative technologies which are intended to improve energy efficiency and construction processes. My focus will be on innovative technologies for sustainable construction, which concentrates on the feasibility of state-of-art fuel cells or net-zero bioenergy alternatives for residential construction, as well uses for material selection and energy system retrofitting.

Research Ambitions

The mission of the Economics of the Sustainable Built Environment (ESBE) Lab, which I funded at Georgia Tech in fall 2009, is to develop the state-of-the-art financial models for enhancing efficient and effective investments in built environment assets. Avoiding under- or over-investment contributes directly to the objective of sustainable development, which aims to maximize future benefits considering the resources used. Examples of Research Initiatives are:

  • Energy-efficient green buildings: Flexible Technologies and Systems for Green-Convertible Buildings. This project is a timely effort to extensively identify, model, and analyze flexibility in sustainable building design. Development of a flexibility identification framework will provide a novel approach for building designers and retrofitters to enhance the future utilization of renewable energy technologies, such as PV Systems, and facilitate the conversion of existing buildings to energy-efficient buildings.
  • Transportation systems: Economic Analysis of Public-Private Partnership (PPP) Highway Projects under Traffic Uncertainty. Public-Private Partnerships (PPPs) have often failed primary due to the lack of proper financial analysis and inappropriate risk sharing mechanisms between public and private sectors. In this research program, we use the real option theory to evaluate the financial performance of PPPs under evolving tolled-road revenue uncertainty.
  • Healthcare planning and design: Enhancing the Value of Healthcare Facilities by Flexible Design and Planning. Uncertainty about healthcare environment is considerably important for healthcare infrastructure planners and hospital designers. Incorporating appropriate flexible features in planning and design of healthcare facilities is an effective strategy to manage uncertainty about the healthcare environment.
