  1. 1. CRI Think Tank Charrette #2 Designing the Center for Community Renewal  Energy, Green Systems & Learning Environs October 17-18, 2008 10.29.08 Building Green Community Renewal International (CRI) Think tank Charrette #2 – Designing the “Center for Community Renewal” (CCR) 10.17-18.08 Focus Area One: “Building green – impacts & systems integration” Discussion Panel: • Michael Garrison, Professor, University of Texas Architecture • Don Shea, Director, Shreveport Downtown Development Authority Focus Area Two: “Shaping the Learning Environments of the CCR” Discussion Panel: • Harold Ledford, PhD. curriculum development & learning specialist for CRI • Barbara Colvin, ASID, learning environments design specialist for MHSM University of Texas Architecture Graduate Student Charrette Teams: John Christopher Buono Tracie Ann Cheng Albert Anthony Palacios Richard William Crum, Jr. Jenna Elise Kamholz Lauren Almy Kohlhoff Edna Ledesma Adam Baxter titrington Cheng Cheng

  3. 3. CRI Think Tank Charrette #2 Designing the Center for Community Renewal  Energy, Green Systems & Learning Environs October 17-18, 2008 10.29.08 Materials Conservation Reuse: Brick: East facade Glass: South & West Façade Concrete: Frame & (Garage) From the neighboring community: • Large steel working industry • Brick is a dominant regional building material Existing Structure: Less modification = more reuse Reduce: Modular: Less waste Surface Area Configuration: • Sphere is ideal; cube is most simple geometric form • Complex configurations use more material per unit of volume. • Finish materials = exposed structure Recycled / Recyclable: Steel 60% recycled content: • Scrap material based concept. Example of melted guns or recycled car materials. Housing scrap: • Recycled furniture, wood flooring from row houses… Polyethylene, polymers & all plastics: • (HPDE) made from recycled materials but not recyclable • PTE: recycled nylon carpet • Styrene from recycled plastic Organic Fabrics: • Rubber Tires Glass & Paper: • Energy to reuse is high Aluminum & Stainless Steel Reduce  Reuse  Recycle
  4. 4. CRI Think Tank Charrette #2 Designing the Center for Community Renewal  Energy, Green Systems & Learning Environs October 17-18, 2008 10.29.08 Goal: Carbon Neutral Underutilized & Local: Pecan, Mesquite, Long Leaf Pine, Clay Brick Certified: R.O. Martin: Only certified within 500 miles Engineered: Parallam, LVL, MDF: • Not Necessarily structural but utilized for trim & finish materials. Underutilized, local materials, certified, engineered, smart low embodied energy Smart: ETFB, Glass Technologies • Electro chromic, electro thermal, glass reinforced polymers… Low Embodied Energy: Local, Wood not Bamboo: Carbon Balanced: Wood CO2 Producers = CO2 Sequesters • Planting trees contributes if CO2 is unbalanced through design. 10% of the CO2 emissions produced in the U.S. comes from the concrete hydration process:

CRI Think Tank Charrette #2 Designing the Center for Community Renewal  Energy, Green Systems & Learning Environs October 17-18, 2008 10.29.08 Energy Conservation 15% 10% 5% 40%30% By reducing lighting loads & other heat generators the building energy load can be reduced by More than 60% IES Lighting  Average wattage / s.f. = 2 watts / s.f.  Goal energy wattage ≤ 1.3 watts / s.f. Lighting load example: Existing = 150,000 s.f. New = 150,000 s.f. 300,000 s.f. x 2 watts 600,000 watts x 3.41 BTU/w 2,046,000 BTU ÷ 12,000 BTU/ton Lighting = 170.5 tons AC Goal for lighting load: Reduce load to 1 watt / s.f. = 170.5÷2= 85.25 tons Target Goal = .5 watts / s.f
  19. 19. CRI Think Tank Charrette #2 Designing the Center for Community Renewal  Energy, Green Systems & Learning Environs October 17-18, 2008 10.29.08 Lighting Strategies A. Better Lights : CFL, LED, Fiber Optic B. Glare free Lighting : Task, Ambient lighting C. Brightness Ratios : 70% walls, 80% ceilings, 50% work surface, 20% floors D. Lighting Controls : Education, timers, sensors, photocell E. Day lighting : Goal = .5 watts per square foot Day Lighting Goal : Daylight factor for Louisiana sky vault = (1000 FL )(2%) = 20 FC Strategies : 2%  General Spaces / rooms 5%  Conference / Office 8%  Atrium / Lobby / Public Areas Example: (85 tons)(≥ 20% goal for day lighting) = 17 tons 85 tons – 17 tons reduced from daylight = 68 tons for lighting (60% improvement from 170.5 tons per IES 2 watts / s.f.)
