Laney indoor environmental quality edited version may 2010

  2. 2. OBJECTIVES – <br />Learn the basics Indoor Environmental Quality:<br />Why is IEQ important?<br />What are Indoor Pollutants?<br />What are VOCs?<br />Strategies to Improve IAQ<br />Materials Selection Attributes for Occupant Health<br />LEED and GreenPointcredits related to materials & indoor health<br />Third-Party Product Certifications <br />Ventilation, HVAC Systems, and IAQ<br />
  3. 3. Why IAQ Is Important<br />On average, Americans spend 90% of their time indoors.<br />Indoor air is often more than 10 times (and sometimes more than 100 times) more polluted than outdoor air.<br />
  4. 4. Indoor air pollutants contribute to asthma, as well as other immediate and long-term health problems.<br />More than $60 billion per year in medical costs can be attributed to poor indoor air quality.<br />
  5. 5. IAQ improvements could reduce health care costs and work losses from allergies and asthma by 18-25%. (Source: EPA)<br />
  6. 6.
  7. 7. Indoor Pollutants<br />VOCs (volatile organic compounds) from building materials, finishes, and furnishings<br />Various toxic chemicals from cleaning products, solvents, pesticides, herbicides, fertilizers, “air fresheners,” dry-cleaned clothes, perfumes, etc.<br />Mold and mildew, biological/microbial pollutants<br />Carbon monoxide and NO2 (from combustion equip.)<br />Particulates(from wood-burning fireplace, outdoor air pollutants from automobiles, etc.)<br />Tobacco smoke<br />Radon<br />Asbestos, lead (in existing buildings)<br />
  8. 8. VOCs<br />Volatile organic compounds contribute to ground-level ozone (smog) and to indoor pollution. They can off gasfrom materials for years after installation.<br />Types of VOCs include: formaldehyde, benzene, xylene, and toluene.<br />
  9. 9. Formaldehyde<br />
  10. 10. VOCs<br />VOCs can cause respiratory, skin, and eye irritation; headaches, nausea, muscle weakness, dizziness, fatigue; and more serious ailments and long-term diseases. Some VOCs are known carcinogens.<br />
  11. 11.
  12. 12. EPA’s VOC limit rules were created to reduce emissions of VOCs that cause smog. Other types of VOCs, which can compromise indoor air quality, are not measured under these rules.<br />
  13. 13. EPA Indoor Air PLUS <br />13<br />“Specifications were developed based on best available science and information about risks associated with indoor air quality problems, and balanced with practical issues of cost, builder production process compatibility, and enforceability”<br /><br />
  14. 14. Finish Measures<br />14<br />Paints, sealants, adhesives<br />Cabinetry & furnishings<br />Flooring<br />Appliances<br />Invoices, MSDS, cut sheets as documentation<br />Watch for switch-outs during construction (but it’s in the specs!)<br />
  15. 15. 15<br />SF<br />MF<br />SF<br />MF<br />Finishes<br />E2<br />K1<br />Design Entryways to Reduce Contaminants<br />SF/MF - Provide Hard Surface & Permanently Installed Shoe Storage System at Home Entrances<br />MF - Permanent Walk-Off Systems are Provided at All Main Entrances & in Common Areas <br />Manual: Built-in cubby or shelf is req’d, bench isn’t<br />
  16. 16. Finishes<br />16<br />Use Low/No-VOC Paint<br />Field: Documentation is key. Finding cans in field is often difficult and not necessarily indicative of which paint was applied where.<br />

  18. 18. Certification of Products<br />
  19. 19. Low & No-VOC Adhesives<br />Low/no-VOC adhesives reduce toxic gasses like aromatic hydrocarbons<br />Can be used for all interior applications<br />Flooring<br />Countertops<br />Wall coverings<br />Paneling<br />Tub/shower enclosures<br />
  20. 20. Exposed Concrete<br /><ul><li>For slab-on-grade additions or basements
  21. 21. Great for radiant, in-floor heating systems
  22. 22. Durable and easy to clean</li></li></ul><li>Install natural linoleum <br /><ul><li>Replaces vinyl flooring
  23. 23. Contains petroleum-based products or chlorinated chemicals such as PVC which off gases VOCs
  24. 24. Lasts only 7-10 years
  25. 25. Manufactured from natural materials like flax seed, jute, and linseed oil
  26. 26. Can last up to 40 years</li></li></ul><li>“Better” Engineered Sheet Goods<br />Engineered sheet goods (particleboard, medium density fiberboard (MDF) typically uses adhesives that contain urea formaldehyde<br />Alternative sheet goods include materials made without formaldehyde<br />
  27. 27. Low VOC, Water-Based Wood Finishes<br />Conventional solvent-based wood finishes can off-gas for months<br />Low VOC finishes are lower in toxic compounds<br />Can be used in most applications<br />
  28. 28. Low & No VOC Paint<br /><ul><li>Low/no-VOC products are manufactured without:
  29. 29. Mercury or mercury compounds
  30. 30. Pigments of lead, cadmium, chromium or their oxides</li></li></ul><li>Low/no-VOC paints are readily available<br />
  31. 31. Flush out prior to occupancy<br />If solvent-based wood finishes must be used, they should be left to off-gas for 3 to 4 weeks prior to occupancy<br />
  32. 32.
  33. 33. Strategies to Improve IAQ<br />1. Source control / pollution prevention<br />2. Improved ventilation<br />3. Air filtering<br />
  34. 34. Materials Selection Attributesfor Occupant Health<br />Low-VOC / Zero-VOC products (e.g., paints, stains,<br />sealants/coatings, adhesives, solvents, carpeting and<br />padding, upholstery, etc.)<br />Formaldehyde-free, or no added urea-formaldehyde<br />(e.g., in binders for pressed wood products such as particleboard and MDF; insulation)<br />Mold/moisture resistant, or naturally mold inhibiting<br />Free of hazardous substances, e.g., mercury, arsenic,<br />chromium, lead, BFRs, HFRs, PBDE flameretardants, etc.<br />Naturally fire resistant<br />
  35. 35. Materials Selection Attributes forPublic/Environmental Health<br />PVC-free materials<br />Free of hazardous substances<br />Made of natural materials (e.g., renewable, biodegradable, non-petrochemical)<br />Organically grown materials<br />Low-pollution and/or carbon-neutral manufacturing process<br />Clean-burning fireplace insert and woodstoves<br />Note: The selection of energy-saving products also helps protect<br /> public/environmental health (and thereby also indoor health).<br />Reducing fossil fuel consumption reduces air pollution and the emission of greenhouse gases that cause climate change.<br />
  36. 36. Third-Party Product Certifications<br />GreenguardIndoor Air Quality Certified /<br />Children and Schools<br />Green Seal<br />Scientific Certification Systems:<br />Indoor Advantage, FloorScore,<br />calCOMPliant, etc.<br />

  41. 41. Other IEQ Issues, Beyond IAQ<br />Factors that affect occupant comfort,<br />well-being, and productivity/performance:<br />•Thermal comfort<br />• Daylighting/lighting (ample natural/warm light)<br />• Controllability of lighting, windows, HVAC<br />• Views of the outside/landscape<br />• Acoustics<br />
  42. 42. Productivity/Performance Stats<br />IEQ strategies can result in a 6-26 percent improvement in occupant performance. (Rocky Mountain Institute)<br />A study at Herman Miller showed up to a 7% increase in worker productivity following a move to a green, daylitfacility.<br />Over a 30-year period, more than 90% of a building owner’s total costs are personnel-related (vs. only 6% for the cost of designing and constructing the building), so small increases in employee productivity can lead to significant savings.<br />U.S. businesses could save $200 billion in worker performance from IAQ improvements.
