2Why Build Green?The construction and operation of conventional buildings have numerous detrimental effects on the environment, public health, and the economic stability of low-income communities.
3Air pollution Global warming 25% of water use Water scarcity 40% of annual US energy useAir pollution30% of US CO2 productionGlobal warming25% of water useWater scarcity
430% of wood and raw materials DeforestationHabitat loss20% - 40% of solid wasteLandfills
5Childhood asthma and other respiratory ailments Paints, carpets, and adhesives off-gas volatile organic compounds (VOCs). Most composite wood products contain formaldehyde.Childhood asthma and other respiratory ailmentsDioxin is created through manufacturing of many building materials.Increasing rates of cancer
6Greater potential for default or eviction. Utility costs can be up to 25% of expenses after rent.Greater potential for default or eviction.Fewer funds available for education or health care.
7Green building is a tool to help us. We can, and must, build better buildings.Green building is a tool to help us.
8What is Green Building?Green building is a process that creates buildings and supporting infrastructure that:1) minimize the use of resources,2) reduce harmful effects on the environment3) provide healthier environments for people.
9GREEN BUILDING COMPONENTS SITE: site selection, bike storage, building orientation, landscaping, stormwater management, construction recycling.WATER EFFICIENCY: efficient toilets and appliances, efficient irrigation, reclaimed/recylced water.ENERGY/ATMOSPHERE: energy efficient envelope, systems,lighting and appliances, renewable energy, no HCFCs.MATERIALS/RESOURCES: efficient building systems, reused, recycled-content, and rapidly renewable materials.INDOOR ENVIRONMENTAL QUALITY: avoid or eliminate VOCs, formaldehyde,and mold, natural ventilation, daylighting, thermal comfort,views, acoustics
10What’s Driving Green Building? Changing Environmental AwarenessGenerational ChangeTechnological InnovationPopular Interest in DesignFinancial IncentivesMarketing value of greenPolicies and Regulation
11Green Building Is a Process! Green building is a process that creates buildings and supporting infrastructure that 1) reduces harmful effects on the environment, 2) minimizes the use of resources, and 3) develops healthier environments for people.Foster design team collaborationConduct charrette early in design processEstablish performance targetsDevelop cost estimates throughout the design processMaintain ongoing communication and feedback loops

16Guidelines to Structure the Process Tax Credit, Trust Fund, or Lender Criteria
17You’re Doing Integrated Design When All stakeholders are involvedNo single person or professional makes decisions about the projectYou are asked to contribute to topics outside of your expertiseYou are pushed out of your comfort zoneThere is a spirit of creativity and funClear goals and specific performance targets are establishedInnovative solutions are encouragedEveryone is interdependent, other people’s work depends on youThe steps in the process, responsibilities, and timeline are clearYou’re Doing Integrated Design When
20Green Building Benefits GlobalStormwater/RecylingRegional BenefitEnergy andWater SavingsDirect BenefitClimateChange/ForestryHealth/Durability
21Costs of Green Building First cost: cost to purchase.Life cycle cost: costs plus savings for a product’s lifePayback: time needed to recoup additional first costs via long-term savingsReturn on Investment (ROI): overall return over time allows for an “apples to apples” comparisonUseful life -15 yrsPayback - 5 yrsInitial Investment: $150Payback Period: 5 yearsSavings period: 10 yearsTotal Period: 15 yearsTotal savings: $300Annual savings: $20Annual ROI: 13%Savings Period - 10 yrsToilet water: $6/month averageDual Flush Toilet: 40% less waterSavings: $2.50/month
22Top 22 No/Low Cost Green Building Strategies ENERGY1. Maximize natural daylighting2. Place windows to provide good ventilation3. Select a light-colored “Cool Roof”4. Provide overhangs on south facing windows5. Plant trees proximate to east and west facades6. Install whole house fans or ceiling fans7. Eliminate air conditioning8. Use hydronic heating9. Install fluorescent lights10. Install high R-value insulation11. Install Energy Star appliances
23Top 22 No/Low Cost Green Building Strategies WATER12. Design water efficient landscapes13. Install water efficient toilets and fixtures14. Use permeable paving materials15. Install in-line flow restrictorsMATERIALS16. Use 30-50% or flyash in concrete17. Use engineered wood18. Use recycled-content insulation, drywall,carpet, etc.
24Top 22 No/Low Cost Green Building Strategies INDOOR AIR QUALITY19. Use low- or no-VOC paint20. Use formaldehyde-free or fully sealedmaterial for cabinets and counters21. Vent rangehood to the outside22. Install carbon monoxide detectorPost-Construction: Prepare operation andmaintenance plan
25Why Green Affordable Housing? Long-Term Ownership Supports a Life Cycle Approach.Projects are typically owned and operated by the same organization for years -- justifies medium to long payback periods.Dollar Savings Help Low-Income Families Most.Utility costs can be 25% of expenses after rent. More than education or health care.Housing Should be Safe, Affordable and Healthy.Formaldehyde,volatile organic compounds (VOCs), mold and other indoor pollutants can impact children’s nervous and respiratory systems and be a trigger for asthma.Affordable Housing is a Public AssetApproximately $500 million annually in Federal tax credits allocated to housing and combined with state and local bonds, property tax set aside and other funds. It is critical that these assets are well-designed, not create an operation burden, and are long-lasting.
26Getting Started Start with what interests you Use available resources to guide you- Energy Star, local green building programs, LIHTC regsPick a manageable and achievable number of strategies, systems,or materialsMinimize additional costs through integrated design, rebates, and grantsLearn from experience - repeat what works, change what doesn’tAdd a few items to each new projectStep up to Green Communities Initiative or LEED for Homes
