  1. The Green Building Process Lecture 8

  2. The Green Building Process • Stakeholders • Design Charrette • Ecological Design • Construction Operations • Planning Concepts

  3. Sustainability by Design “We can’t solve the problems of the past using the same thinking and methods that created them…” …….Einstein

  4. Integrated Design • “Front-loaded” design • The “whole” building • Life-cycle assessment • Full-cost accounting • All stakeholders • Modeling and verification

  5. Who should be at the table ? • Owner • Architects/engineers • Builder • Facilities managers • Users • Consultants (energy, lighting, water, landscape, ecology, materials, waste) • Others (neighbors, planning & code officials

  6. Design Charrettes

  7. Ecological Design • Solutions grow from place • Make nature visible • Design with nature • Ecological accounting informs design • Everyone is a designer “Ecological Design” Sim van der Ryn

  8. Ecological Design (2) Conventional • Non-renewable energy • Wasteful use of materials and byproducts are discarded to soil, water and air • Compliance with the law is the measure of success • Goals are short term • Design is based on convenience, custom, and economics • Replication and homogeneity are the norm • Systems boundaries are abstract • Nature is manipulated to meet a narrow range of human needs • Done by experts

  9. Ecological Design (3) Ecological • Renewable sources are used to maximum extent • Industrial ecology materials manufacture, reuse, recycling, flexibility, durability • Full life-cycle accounting • Goals are long term • Human and ecosystem health, and ecological economics • Bioregional context determines place specific design • Follows ecosystems boundaries • Nature’s processes and design intelligence replaces reliance on fuels and materials • Full debate and discussion

  10. Sustainable Design & Construction • WHAT WORKS BEST ? • Design / Bid - less flexibility, integration + competitive process, lowest cost • Construction Management - less-competitive, cost, GMP + flexibility, integration, knowledge, GMP • Design / Build - cost-control, less-competitive, capacity + communication, flexibility, creativity, continuity

  11. Sustainable “Process” • PRE-DESIGN • Qualify Design Team • Management Options • Stakeholder Input – include employees & neighbors • Vision and Goals – interdisciplinary design charrette • Sustainability Matrix – environmental, functional & life-cycle cost objectives • Incentives and Codes / Certifications • Benchmarking

  12. SD & C Process (2) • CONCEPT DESIGN • Develop Sustainable Design Concepts • Research and Analyze – feasibility of options, ex. systems & materials • Prioritize Objectives – ex. LEED™ rating level • SCHEMATIC DESIGN • Review Sustainability Objectives • Sustainable Design Evaluation/Revision • Modeling Energy & Life-Cycle Costs

  13. SD & C Process (3) • DESIGN DEVELOPMENT • Sustainable Design Systems and Materials • Outline Green Design Specifications • CONSTRUCTION DOCUMENTS • LEED™ Certification Requirements • Green Specifications • “Check-off”

  14. SD & C Process (4) • CONSTRUCTION • Worker Environmental Education • Sustainable Construction Process – ex. C&D/Erosion • BUILDING COMMISSIONING • As-builts • “Owners Manual” • POST-OCCUPANCY • Occupant Satisfaction • Energy Star™ Benchmarking • “Lessons-Learned” • Certification/incentives

  15. Building Objectives • Programmatic Objectives • Performance Objectives • Financial Objectives • Environmental Objectives • Site, Energy, Water, Materials, Waste, Landscape, Occupants, Operation and Maintenance, Adaptation Objectives • Educational Objectives • Marketing Objectives

  16. Environmental Objectives • Smaller is better • Energy-efficient building  • Use renewable energy • Optimize material use • Water-efficient, low-maintenance landscaping  • Occupants recycling • Design for durability  • Design for future reuse and adaptability • Avoid potential health hazards: radon, mold, pesticides

  17. Environmental Objectives (2) • Renovate older buildings • Create community • Encourage in-fill and mixed-use development  • Minimize automobile dependence • Value site resources • Locate buildings to minimize environmental impact • Provide responsible on-site water management  • Situate buildings to benefit from existing vegetation • Avoid ozone-depleting chemicals in mechanical equipment and insulation 

  18. Environmental Objectives (3) • Use durable products and materials • Choose low-maintenance building materials  • Choose building materials with low embodied energy • Buy locally produced building materials • Use building products made from recycled materials • Use salvaged building materials when possible • Seek responsible wood supplies • Avoid materials that will off-gas pollutants • Minimize use of pressure-treated lumber

  19. Environmental Objectives (4) • Minimize packaging waste  • Install high-efficiency heating and cooling equipment • Install high-efficiency lights and appliances • Install water-efficient equipment • Install mechanical ventilation equipment • Protect trees and topsoil during sitework  • Minimize job-site waste • CERTIFIED ENERGY STAR™ OR LEED™ GREEN BUILDING Environmental Building News

  20. Construction Operations • Reduce “footprint” • Protect landscape and soils • Sediment and erosion control • Recycling debris and soils • C&D Minimization • Prevent “waste” from entering site • Proactive design – site and building

  21. Construction & Demolition Wastes • 136 million tons / year in US • 30% of total US solid waste • Demolition 48 % • Residential 245,000 / yr • Non-residential 43,795 (1995) • Renovation 44 % • Residential 6.75 million • Non-residential 28 million ton • New Construction 8%

  22. Total C&D by Materials • 54 % Concrete • 25% Drywall (residential) • 22 % Wood • 5% Cardboard • 3 % Steel • 2% Brick

  23. C&D Waste Reduction • Waste audit • Markets and service providers • Types of materials • Costs and benefits • Local disposal fees • Reuse and recycle on-site • Reuse and recycle by Contractor • Off-site reuse and recycling

  24. Planning Concepts • New Urbanism • Traditional Neighborhood Development (TND) • Transit Oriented Development • Location efficiency • Transit, walkability, mixed-uses • Urban density, mix of housing types • Sidewalks, porches, “fronts and backs” • Alleys, side and rear garages • Urban and infill locations
