Supply CriteriaGuided by Indoor Air Quality (IAQ) as the standard criteria, the following characteristics represent product considerations used as the baseline in HH (symbol) product sourcing.
(SYMBOL) IAQ: All products/suppliers are selected not only on consideration of the below key factors but on Volatile Organic Compound (VOC) content and any other indoor air quality contaminants.
Toxic Emissions Products that Avoid Toxic EmissionsUsing materials that emit few or no carcinogens, reproductive toxicants, irritants or VOCs is best for the health of building occupants and the environment in general. Conventional products often emit harsh chemicals such as pesticides, formaldehyde, Hydrochlorofluorocarbons (HCFCs)-an ozone-depleting chemical compound commonly used in commercial refrigeration units, air-conditioners and cleaning products-and polyvinyl chloride (PVC)-a plastic that creates dioxin (the most potent known carcinogen), ethylene dichloride and vinyl chloride-all of which can cause severe health problems. Rapidly Renewable ProductsTypically, rapidly renewable products can be harvested within 10 years or less. They are usually biodegradable; however they are not always non toxic (either through added resins or finishes). Sustainable Harvested MaterialsUsing resources or producing materials in a way and at a rate that does not result in the long-term decline of biological diversity, loss of habitat, water pollution or displacement of indigenous peoples. Preferably materials should receive certification from an independent third party. (i.e. Forestry Stewardship Council (QUICK LINK) Resource Efficient Manufacturing ProcessGreen products should be manufactured through processes that minimize energy consumption, produce minimal waste and reduce greenhouse gases. Products made with Salvaged, Recycled or Agricultural Waste Content
Products that Reduce Pollution or Waste from OperationsExamples would include wastewater disposal systems, masonry fireplaces recycling bins. Alternative wastewater disposal systems reduce groundwater pollution by decomposing organic wastes or removing nutrients more effectively. Masonry fireplaces burn fuel-wood more completely with fewer emissions than conventional fireplaces and wood stoves. Recycling bins and compost systems enable occupants to reduce their solid waste generation. Products that Reduce Storm water pollutionPorous paving products and green (vegetated) roofing systems result in less storm water runoff and thereby reduce water pollution. In addition, storm water treatment systems can reduce pollutant levels in water that is released. Fixtures & Equipment that Conserve WaterAt least 20% water savings can be found by using low-flush toilets, waterless urinals and low flow showerheads. Products that Reduce Heating and Cooling LoadsExamples include structural insulated panels (SIPs), insulated concrete forms (ICFs), autoclaved aerated concrete (AAC) blocks, and high-performance operable windows and glazing. Equipment that Conserves EnergyEnergy saving products are readily available and are often certified by organizations like Energy StarŪ. Energy efficient products include compact fluorescent lighting (CFL), efficient appliances and heaters but they also include task lighting, occupancy sensors and products that improve daylight. Renewable Energy Equipment & TechnologyEquipment and products such as solar water heaters, photovoltaic systems, and wind turbines enable us to use renewable energy instead of fossil fuels and conventional electricity. Products that Block the Introduction, Development or Spread of ContaminantsCertain materials and products prevent the generation or introduction of pollutants-especially biological contaminants-into occupied spaces. Duct mastic, for example, can block the entry of mold-laden air or insulation fibers into a duct system. "Track-off" systems for entryways help to remove pollutants from the shoes of people entering. Coated duct board-compared with standard rigid fiberglass duct board-prevents fiber shedding and helps control mold growth. Products that qualify for 3rd party CertificationProducts that have been certified by qualified product certification systems such as Green Seal, EnergyStar or GreenGuard automatically qualify after verification of current certification status and meeting the baseline standard of indoor air quality. There are some supply chains that based on our research and knowledge of the product or process would be certifiable. I these cases we will work closely with our supplier to get them certified. The following criteria are essential components of green building products individually are not enough to qualify acceptable products.
