Green Engineering & Sustainable Design
Transcript of Green Engineering & Sustainable Design
…should be suitable for a wide variety of offices
…address an important source of office-generated waste or pollution
…should be novel, to attract attention to the potential of green products Identify Evaluation Criteria & Constraints -Serve a useful function in an office
-Reduce the use of non-renewable energy
-Be easy to install/integrate into the office environment If your design is successful and effective, it will: Ideation Constructing a Product Mock-Up Preliminary Ideas
Integration with rest of office 20%
Effectiveness at reducing energy use 20%
Effectiveness at reducing water use 10%
Ease of installation 5% Questions? Beginning Research Evaluating problems in the office Offices visited:
BK Dean's Office; TC Dean's Office; FES Business Office; Creative Art Workshop (New Haven Community Art School); Yale Office of Procurement
Other professionals interviewed: Staples Sales Representative, Professional Plastics Representative Conclusion The ElectroMat - a green office product
Drawbacks - cost
Will it sell? Home Depot & Construction Pics Evaluation of Materials Evalutation of Product Ideas Impacts associated w/ manufacture; Long life; More efficient; Fully recyclable; Used in Prius PVDF Nickel metal hydride battery The ElectroMat Dimensions of ElectroMat = 50"x38"x1"
A sheet of PVDF (30"x18") underneath a layer of carpet.
A drop of 0.50" beneath PVDF to ensure PVDF deflects when stepped on.
Thin battery stored in the side of the mat, easily removable for use
Small LED system that lights up as battery charges and is fully light when battery is fully charged
Cost All materials besides the PVDF will cost about $50
The PVDF is the most expensive material - $178.56, quote from Professional Plastics
High-end "green" bamboo floor mat: Anji Mountain Mat = $147 Product Specifications Thank You Life Cycle Considerations Recycled Rubber Adequate supply of recycled rubber; Fewer manufacturing impacts than plastic; Reasonably durable; Recyclable Carpet/Dye Can use recycled PET/nylon carpet; Uses less energy to manufacture than virgin carpet; Dying process less polluting; Less durable during use phase; Not best end of life option Adhesive No recycled content; Low energy use; Non-toxic; VOC free option; Less desireable than alternative (clips) for end-of-life. Chemically manufactured; Energy intensive, But low mass; More durable; Process for taking off fluorine. Overall was better enviro-option Time for ElectroMat to make up the difference in price with the bamboo floor mat: ~5 years Extracting energy from human motion 100% recycled products Built environment:
modular furniture + recycled carpet Integrated shredding and recycling Cartridge refill, stacking & takeback Staples' solution Staples' solution
Effectiveness at reducing energy use
Effectiveness at reducing water use
Ease of installation
Integration with rest of office Modify Evaluation Criteria + novelty! Integration into offce -Compare: size, shape, height, texture
-Non-skid, no cords, sloped edges - no tripping
-Installation = lay it down
-Opportunity for corporate branding
-Emergency power source High traffic areas -Efficiently scavenge energy; prevent "traffic lane grey"
-Average lifespan industrial carpet: 7-10 years Interactive zones -Enagage, entertain and exercise customers

Hi guys, not sure if you want to add these as research inspirations or not, but I think (at least on paper), the use of PVDF in our design has some improvements over this MechE project from a few years ago...
