Learn what the chemical ‗nasties‘ are, know which are in the products you use, and think twice about using them • Find safer commercially-produced alternatives • Use safer alternatives found around the house (the home ‗formulary‘) The Green Roundtable (copyright © Green Roundtable 2007)
  • 27. Addressing the risks, cont. • Address moisture infiltration and moisture sources within the home • Reduce infiltration of contaminants • Provide adequate ventilation • Store chemicals away from living spaces • Understand risks associated with removal/ demolition and disposal, and take adequate precautions Note: Sometimes a less-than-benign maintenance routine is better than the alternative of premature wear/ replacement with its associated resources use The Green Roundtable (copyright © Green Roundtable 2007)
  • 28. Some product use rules-of-thumb • Mechanical methods often safer- e.g. good old- fashioned elbow grease • Water-soluble products often more benign than solvent-based • Non-aerosol-dispensed products often safer • Don‘t pull out the ‗big guns‘ until you need them! begin with the simple The Green Roundtable (copyright © Green Roundtable 2007)

Bathroom • Add a cup of straight white vinegar to the toilet, swish around and let sit for a while • Add ½ cup borax to toilet; scrub; let it sit several hours or overnight • To remove mildew soak a sponge with a 50/50 solution of vinegar and water, dip in borax powder and scrub The Green Roundtable (copyright © Green Roundtable 2007)
  • 67. Clogged drains • Keep drains from clogging in first place by treating them with a kettle full of boiling water a couple of times a month • Begin with mechanical means— plunger, snake; clear clog via drain trap or clean-out plug. When using a plunger to clear a clog pull stroke works best; create better suction with some standing water The Green Roundtable (copyright © Green Roundtable 2007)
  • 68. Clogged drains, continued • Keep drains clear by pouring half a cup of baking soda followed by a cup of straight white vinegar down the drain once a month; let stand for a while and follow with boiling water • Pour kettle of boiling water down drain; follow with ½ cup baking soda and ½ cup salt and 1 cup of boiling water; let stand; finish with 1 - 2 cup of heated straight white vinegar (careful of vapors!) and a plunger if necessary Enzymatic cleaner The Green Roundtable (copyright © Green Roundtable 2007)
  • 69. Air fresheners • Citrus peels • Baking soda • Activated charcoal • Volcanic rocks • Aromatic oils • Ventilation! Open a window! The Green Roundtable (copyright © Green Roundtable 2007)

  • 71. Pesticides/ herbicides • Use 1 or 2 teaspoons of dishwashing liquid to a pint of water in a spray bottle to kill many house and garden plant pests, including aphids and scale; or use commercial variety insecticidal soap like Safer‘s • Wiping the leaves with rubbing alcohol may also work • Hot pepper wax sprays, dormant oils and sticky traps are also more benign control measures (check labels/ manufacturer for affected insects) The Green Roundtable (copyright © Green Roundtable 2007)
  • 72. Critters (inside the house) • Use diatomaceous earth for to keep ants & cockroaches at bay (be careful not to inhale dust) • Seal entry points • Use 50/50 mixture of white flour or corn starch and boric acid to control cockroaches and silverfish • Keep food prep areas clean! The Green Roundtable (copyright © Green Roundtable 2007)
  • 73. Combustion appliances • Keep them well tuned • Provide a dedicated combustion air source • Keep flue pipes clear; use a chimney cap • Use an adequate number of smoke and CO detectors!!! The Green Roundtable (copyright © Green Roundtable 2007)

  • 79. Asbestos and Lead • Generally safe if left undisturbed • Sealing or encapsulating can be an effective strategy • Don‘t flame strip or sand paint suspected of containing lead • Flush copper cold water pipes first thing in morning to avoid lead leached from solder • Use qualified professionals for identification/ testing/ mitigation!! The Green Roundtable (copyright © Green Roundtable 2007)
  • 80. Moisture-related problems • Control ice dams, basement water infiltration • Don‘t ventilate basements and crawl spaces in the summer!!! • Control humidity with a dehumidifier if necessary • Vent all bathroom fans and dryer ducts to outside • Use qualified professionals for testing/mitigation The Green Roundtable (copyright © Green Roundtable 2007)

  • 85. Dust, dust mites • Seal building envelope to control dust • Use HEPA rated vacuum cleaners and air purifiers • Use walk-off mats (commercial grade) at doorways • Wash bedding in hot water • Avoid wall-to-wall carpeting The Green Roundtable (copyright © Green Roundtable 2007)
  • 86. The trouble with turf Lawn maintenance routines create multiple threats to the environment through: • Heavy fertilizer requirements • Pesticide and herbicide use • Need to mow regularly and the resources that this requires (gas, electricity, oil, spark plugs, etc) • Water use They are energy and resource intensive. If possible, LOSE THE LAWN! Substitute ground covers, shrubs, flower beds, rock gardens, etc. The Green Roundtable (copyright © Green Roundtable 2007)
  • 87. Lawn care (if you must) Follow good general turf management practices: • Don‘t cut too short • Aerate and de-thatch • Water deeply only once a week (~ 1‖ of water); this promotes deep root development • Use a drought-tolerant seed variety suitable for this region • Employ organic fertilizing and pest management practices (next) The Green Roundtable (copyright © Green Roundtable 2007)
  • 88. Organic turf management • Mow with an old-fashioned reel mower • Leave clippings on lawn to return nutrients (mow often) • Apply compost to lawn • Fertilize with a home-brew fertilizer in a hose-end sprayer (see next slide & Jerry Baker resources) The Green Roundtable (copyright © Green Roundtable 2007)
  • 89. Organic turf management, continued • Tolerate a few weeds! • Hand-pull weeds • Control tough weeds with spot application of a ‗home-brew‘ solution • Apply corn gluten meal (CGM) as a pre-emergent weed control and fertilizer The Green Roundtable (copyright © Green Roundtable 2007)
  • 90. Lawn Tonic (Spring) • 1 cup Epsom salts • 1 cup liquid dish soap • 1 cup Listerine mouthwash • 1 cup household ammonia (can be lemon variety) • 1 can of beer • This is a slight modification of a Jerry Baker (The Impatient Gardener) recipe. Apply with hose-end sprayer after mowing, dethatching and seeding; treats around 2500 sq. ft.; though some of the ingredients may not be ‗fit‘ for household use (e.g. ammonia), they‘re relatively benign when applied to your lawn The Green Roundtable (copyright © Green Roundtable 2007)
  • 91. Spot herbicide for lawns Mix 8 oz of straight white vinegar, 2 oz of lemon juice, 2 tbs table salt, and 1 tbs dishwashing liquid in spray bottle Only kills above-ground parts of dandelions, etc, but may eradicate them with repeated application; usually doesn‘t affect grass; works best in full sun The Green Roundtable (copyright © Green Roundtable 2007)
  • 92. Corn-gluten meal • Natural pre-emergent weed and crabgrass killer • Provides slow-release nitrogen to lawn • Apply when: - Forsythias in bloom - Soil temperature is ~60 deg. F. • Generally applied in late April • It really works and it‘s available locally! The Green Roundtable (copyright © Green Roundtable 2007)
  • 93. Green Auto Care • Don‘t wash your car, flush your radiator or change your oil at home; let the professionals do it • If you do wash your car at home, washing it one section at a time is more efficient. Washing the car on the lawn reduces pollutants in storm drains and soil organisms help to break down detergents; use oily hair shampoo (biodegradable) solution as car wash; use more concentrated solution for road tar The Green Roundtable (copyright © Green Roundtable 2007)
  • 94. Green Auto Care • If a degreaser is needed, use commercial products containing d-limonene or use1/2 teaspoon washing soda (sodium carbonate, soda ash or sal soda), 2 tablespoons white vinegar, 1/4 teaspoon liquid soap and 2 cups hot water • Keep tires inflated- improves mileage/ tire longevity The Green Roundtable (copyright © Green Roundtable 2007)
  • 95. Green Auto Care, cont. Best green “auto care” tip: Reduce Your Driving! Less driving = less wear & tear = less maintenance = fewer maintenance products and repair parts Walk, bicycle, carpool, use public transportation…you know the drill! The Green Roundtable (copyright © Green Roundtable 2007)
  • 96. De-icers • Favor mechanical ‗traction control‘; Use sand, kitty litter or sawdust, or some combination of these • Always ‗cut‘ de-icers, especially rock salt, with sand; a little rock salt goes a long way • Don‘t use indiscriminately; apply only where needed! • Potassium Chloride (KCl), Magnesium Chloride(MgCl), Calcium Chloride (CaCl) and Urea can be more benign alternatives to rock salt- these can sometimes provide needed nutrients to soil if they end up on lawns, etc. (KCL & Urea can burn lawns; some de-icers stain carpeting & flooring) The Green Roundtable (copyright © Green Roundtable 2007)
  • 97. De-icers, continued • Try to sweep up sand/ salt after walkways/ driveways are dry as it can clog storm drains; re-use it if practical • Store de-icers indoors at room temperature to increase effectiveness and minimize quantity needed • Clear snow & ice barriers that prevent drainage of paving & contribute to ‗refreeze‘ ice patches The Green Roundtable (copyright © Green Roundtable 2007)
  • 98. Additional considerations: • Maintaining IAQ during the construction process - Effective isolation of work areas - Ventilating during process - Pre-occupancy flush-out • Effectively managing construction waste - Minimize in the first place using material- efficient design strategies - Recycling/ diverting where possible The Green Roundtable (copyright © Green Roundtable 2007)
