Buildings: Energy use modelling

In order to evaluate the most promising engineering strategies to address planetary level issues such as climate change, one needs tools that can span the breadth of the size scales involved. In this project we are concerned with energy use in the product manufacturing sector. Our focus is on the factory energy environment that needs to combine manufacturing process performance with building performance. We develop a high level energy model that incorporates the process equipment mainly as internal heat sources, as well as material flows including air exchange rates, and incoming raw materials, subcomponents and packaging, and outgoing products, co- products and wastes. The building model includes work inputs, lighting and other internal heat sources as well as heat transfer through the building envelope. The objective of this model is to provide a high level aggregate quantitative interpretation of the factory energy performance. The model is general enough to apply to any building in any part of the world, provided certain basic parameters are known.

Automobile assembly plant: Energy used and carbon emitted

As a special case of our building energy modeling, we develop a detailed model for any automobile assembly plant. Using global data we develop a model that is representative of an average global plant and test energy improvement strategies for their effectiveness.

RAFFT Project: Modeling the benefits of a new incremental sheet forming technology

Rapid and Flexible Forming Technology (RAFFT) is a new sheet metal forming process in which heavy fixed dies are replaced with computer controlled mobile tools.

The project is part of a three-year, $7.04 million U.S. Department of Energy grant to advance next-generation, energy-efficient manufacturing processes. Led by Ford, other collaborators include Northwestern University, The Boeing Company and Penn State Erie. EBM are leading the collaboration in assessing the potential energy, carbon and cost benefits of the technology.

Additive manufacturing: Tracking the energy use of emerging technology

This project focuses on the energy and resource efficiency of “additive manufacturing” technologies.

By categorizing and studying different additive manufacturing methods, we will compare it with conventional manufacturing and evaluate the feasibility of its application in injection molding tooling. To fully assess the environmental impact of additive technologies, the analysis will include pre- and post-processing.

Single stream recycling: Modelling of material, exergy and energy flows

We are working with the waste managment plants that Ferrovial operates all over Spain on increasing the recovery of recyclable materials from municipal solid waste.
