This document discusses embodied energy of building materials. It defines embodied energy as the total energy required for a product's life cycle from extraction of raw materials through manufacturing, transportation, installation, use and disposal. It then examines how embodied energy is distributed in building construction sectors in the US. The document also describes an embodied energy calculator tool called Mbod-E and provides two case studies of its use in evaluating material selection for Cannon Design offices in Chicago and Washington D.C., allowing comparisons between the embodied energy of choices. It concludes that considering embodied energy alongside operational energy can help the building industry reduce its environmental impact.

3. INTRODUCTION

4. Defining Embodied Energy
- Embodied energy = the sum of energy inputs to make a product
- For full cradle-to-grave cycle, energy inputs from:
• Extraction of raw materials
• Transportation to factory
• Manufacture of product / components
• Assembly of product / system
• Transportation to site / point of sale
• Installation / construction
• Maintenance
• Replacement
• Disposal / re-purposing / recycling

5. Defining Embodied Energy
- Embodied energy for building materials is often measured cradle-to-grave
(extraction, transportation, manufacture, packaging)

6. Defining Embodied Energy

7. How Is Embodied Energy Distributed In Building Construction?
U.S. energy consumption by sector

9. Mbod-E Calculator
- Goal of calculator: calculate embodied energy of building materials, assemblies,
and entire projects
- Resources used:
• ÌNVENTORY OF CARBON AND ENERGY(ICE )database
• Product-specific LIFE CYCLE ASSISSEMENT(LCAs) from manufacturers
• Information acquired from manufacturers (when available)
- Current format: Excel calculator

- REQUEST FOR PROPOSAL
(RFP) language sent to furniture
manufacturers
- Proposals passed to research team
for evaluation
As part of Cannon Design’s office relocation, we are
conducting research on the embodied energy of the
products we are using in the design of the space. This
information will inform design decisions we will make on
this project. For each product, please provide the
following information:
• Product Name
• Locations of manufacture and finalassembly
• Life Cycle Assessment report for the product, which
includes cradle-to-gate embodied energy assessment
• Complete list of all component materials andtheir
respective weights

26. CONCLUSION

27. Conclusions
Building life-cycle does matter
Consider the balance between embodied energy and operational energy
The building industry is learning and you can help engage all sectors

28. Conclusions
How can manufacturers contribute?
- Increase product transparency around embodied energy — very soon it will matter
to your bottom line
- Drive waste from the manufacturing process and innovate new technologies
