Incorporating sustainability into building and infrastructure design requires
simultaneous consideration of performance, costs, and environmental impacts.
Sustainable design is an optimization of these three elements. The engineering and
design community quantifies performance in the design process, but cost and
environmental impacts are typically considered when the design is mostly complete,
if at all. This presentation will summarize research on quantitative assessments of life
cycle costs and environmental impacts in the design of buildings and pavements.
Emphasis is placed on incorporating uncertainty into performance, cost, and
environmental impact assessments given the long life of these applications. In
addition, engineering methods to quantifying the operational impacts of buildings and
pavements will be demonstrated, including repairs due to natural disasters for
buildings, and excess fuel consumption of vehicles driving on pavements. The
importance of optimizing performance, cost, and environmental impacts will be
highlighted with examples in both applications.
Doctor Jeremy Gregory (PhD in Mechanical Engineering, MIT) is a research
scientist in the Department of Civil and Environmental Engineering and the
Materials Systems Laboratory, and is the Executive Director of the Concrete
Sustainability Hub at the Massachusetts Institute of Technology (MIT). Dr.
Gregory studies the economic and environmental implications of
engineering and system design decisions, particularly in the area of
materials production and recovery systems. Research topics include
product and firm environmental footprinting, manufacturing and life-cycle
cost analysis, and characterization of sustainable material systems. He has
applied these methods, often with industry partners, to a range of different products and industries
including pavements, buildings, automobiles, electronics, consumer goods, and waste treatment and
