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
Energy to manufacture product Product or
Building

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

10. CASE STUDY :- CANNON DESIGN OF CHICAGO OFFICE

13. Project:
- Relocation of Cannon Design
office in Chicago
- 60,205 sf floor in office tower
Sustainability goals:
- LEADERSHIP IN ENERGY
AND ENVIRONMENTAL
DESIGN(LEED).
- Reuse materials and furniture
whenever possible
- Reduce embodied energy of
project overall
Case Study: Cannon Design Chicago Office

14. Collaboration with research team:
- Provided feedback on calculator
- Advice led to creation of Material LIFE
- Provided preliminary material
selection lists for embodied energy
comparisons:
• Carpet
• Write-on wall finishes
• Furniture

16. Furniture selection:
- 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
