Design Review 1 Cindy

2 Agenda Team Introduction Project Background Problem Statement
Additional Deliverables Use Scenarios Customer Requirements Benchmarking Engineering Requirements HOQ Risks Project Plan Concerns Next Steps Cindy

3 Team Intro and Roles Peter Chynoweth - Mechanical Design Lead
Jamiya Cook - External Project Manager Adrian Izbicki - Materials Design Lead Cindy Widergren - Internal Project Manager Cindy

4 Project Background: Nicaragua and 4 Walls
El Sauce, Nicaragua Largest country of South America Rural “cowboy” small-town atmosphere High unemployment, primarily agricultural, has growing opportunities for economic development 4 Walls Help families obtain their homes Build a potential small business for some people in Nicaragua Jamiya

5 Project Background: Biochar
Made from many types of biomass including agricultural wastes Being tested as a component in building materials and are starting to test biochar amended with concrete Used to improve humidity control and could potentially have many other benefits Ithaka Institute - non-profit foundation that researches biochar teamed up with 4 Walls to see if roofs could be made from biochar Peter

6 Project Background: Biochar
Peter Info: Biochar is created by the thermochemical decompositions of organic materials at elevated temperatures in the absense of oxygen. This process is called pyrolysis

7 Problem Statement Current State Desired State Project Goals
4 Walls builds homes in Nicaragua but the roof construction is not optimal Desired State Create roofs that are less expensive, made of local products, quieter in the rain and do not create a large solar gain by utilizing biochar Project Goals Analyze current roofing design Design a biochar roofing that can be made and repaired locally Constraints Roof must be able to be built with local materials and tools for less than $400 Adrian

8 Deliverables Working Roof Prototype Test Documentation
Molds for Manufacturing Material Mix (Biochar/Concrete) Instructions for Installation Schematics/Design Models Adrian

9 Use Scenario: Construction of the Roof

11 Installed Cost per sqft ($)
Benchmarking Cost ($/sqft) Weight (lbs) Installed Cost per sqft ($) Lifespan (years) Modularity (sqft) Wind Resistance (mph) Metal Sheets 1 1.5 7 50 42 140 Tar Tiles 2 1.20 20 3 110 Clay Tiles 2.50 10 4 45 *Benchmarks are in America Peter

12 Engineering Requirements
Peter

13 House of Quality Compared customer requirements to engineering requirements Cindy

14 HOQ Insights Most important ER: Total Cost Keep cost down
Number of Skilled operators Time to install roof Takeaways: Keep cost down Keep installation simple Tradeoffs: Add more desired features, increase cost Keep in mind roof weight, dimensions, ability to hold a person, decreases install time Cindy

15 Risks Cindy

16 Current Project Plan and WBS
Jamiya

17 Concerns Having our first meeting with one of our main customers today
Will have to ensure that all of the previous work aligns with their requirements Jamiya

18 Future Plan As a team, where do you want to be in three weeks at your next review? Developing Alternatives Concept Selection Functional Analysis Feasibility Analysis Risk Assessment Test Plan Each individual team member has certain action items before the next review Jamiya
