Green building products and materials

Use green building productsSelection of environmentally preferable products and materials is an important step in sustainable building. Finishes and materials should have low toxicity to protect indoor air quality. Energy-efficient products are key to meeting green building objectives and balancing integrated systems. Recycled products should be used whenever possible to conserve natural resources. Sustainably harvested products help protect natural ecosystems.

Environmentally preferable

The federal government defines environmentally preferable products as goods that have a lesser or reduced effect on human health and the environment when compared to competing products that serve the same purpose. Environmentally preferable attributes include reduced toxicity, the use of recycled materials, and increased energy efficiency.

Minnesota Building Materials Database: A Tool for Selecting Sustainable Materials

Minnesota Building Materials DatabaseThis online database is a vehicle to document, evaluate, and disseminate information on sustainable materials, products, systems, and services for the commercial and residential building construction industry in Minnesota. The database uses lifecycle thinking to analyze sourcing, health, end of use, LCA tools, properties, and costs. Products that reflect the industry standard are compared with those that exhibit improvement over this standard ("good") or reflect significant advancements in environmental, economic and social performance ("better").

The database was developed by the Center for Sustainable Building Research with grant funding from the state Environmental Assistance grant program:

Where to find green building products

PDF Document Where to find products for building green 2011 (w-hhw1-26.pdf)

Green building looks at the whole house and how systems interrelate, including impacts on the health and comfort of occupants. Choosing products is an important part of the process.

Some green building products have measurable benefits for homeowners, such as using less electricity or not off-gassing formaldehyde. Others have attributes that likely reduce their impact on the environment, such as recycled content or local manufacture. Selecting products with multiple benefits and attributes is the best approach.

Environmentally Preferable Purchasing Guide

The Environmentally Preferable Purchasing Guide (EPPG) is a reference tool for Minnesota government and school purchasers who want to make wiser purchasing choices. It will help you find ways to reduce workplace hazards, consume less energy, and protect natural resources by identifying environmentally preferable alternatives in 16 green building product areas and building services. Information on cost and performance is included, as well as identifying places where you can find these products.

Product standards and certifications

A number of organizations have developed standards or criteria for evaluating environmentally preferable products. Many of these organizations test or certify the products.

ASTM International: Sustainability in the Buildings Industry: How ASTM Standards are Addressing the Trend
  This August 2001 Standardization News article includes contains links to ASTM International's Subcommittee on Sustainability and two new sustainability standards.

Comprehensive Procurement Guidelines (U.S. EPA)
  The federal Environmental Protection Agency uses the CPG to designate items that must contain recycled materials when purchased by federal, state and local agencies, or government contractors, using appropriated federal funds. The CPG include 8 product categories and are updated every two years. The EPA also issues guidelines recommending levels of recycled content for these items.

Energy Efficiency and Renewable Energy Network
  The U.S. Department of Energy site provides detailed information about building topics including the building envelope, space heating and cooling, water heating, lighting, appliances, office equipment, and building electrical equipment.

Energy Star
  In 1992, Energy Star was introduced by the U.S. EPA as a voluntary labeling program identifying and promoting energy-efficient products. It has expanded to cover new homes, most of the buildings sector, residential heating and cooling equipment, major appliances, office equipment, water coolers, lighting and more.

Certified wood
  To facilitate access to FSC-certified wood products, the Rainforest Alliance offers the 50-page SmartGuide to Green Building Wood Sources (PDF4.5Mb). Product categories include cabinets & casework, decking, doors & windows, engineered wood, exterior applications, flooring, framing lumber, millwork, office furniture, and plywood. Information is compiled from a number of sources, including FSC, SmartWood, and Metafore databases, individual source interviews, and company Web sites.
   The Forest Certification Resource Center has information about the various North American forest certification systems, a tool to confirm the certification status of specific companies, and a product database searchable on a variety of criteria (certification program, product, species, supply chain position, supplier locations, and supplier name).

GreenguardGREENGUARD™ Product Guide
  Products listed by Greenguard have been tested according to stringent environmental chamber testing protocols, and meet current requirements of the U.S. EPA, the state of Washington, U.S. Green Building Council, and Germany's Blue Angel ecolabel. A new standard for Children & Schools sets emissions criteria for building materials, furnishings, finishes, and cleaning products to be used in school and daycare facilities, including a "body burden" correction factor and a limit on phthalate emissions.

GLP logoGreen Label Plus (Carpet and Rug Institute)
  CRI has created an independent testing program to certify products that meet or exceed the standards of California 01350 and Collaborative for High Performance Schools (CHPS) for indoor air quality for low-emitting materials in commercial settings. Carpets undergo a 14-day testing process to measure emission levels of 13 chemicals. The site contains a list of Green Label Plus approved carpet products and a fact sheet about the program.

Green SealGreen Seal
  Green Seal is an independent, nonprofit organization that sets environmental standards. Companies pay to have their products tested, and a "Green Seal of Approval" certification is given to products that cause less harm to the environment.

Master Painters Institute Green Performance Standard
  MPI's Green Performance Standard (GPS 1-05) contains a list of banned ingredients and sets a maximum allowable level of volatile organic compounds (VOCs) for each paint category. In most cases, the VOC thresholds match the strictest of the guidelines in widespread use. Conformance with GPS 1-05 requires a paint to meet MPI’s performance standard for its category and conform to the green requirements. MPI relies on manufacturer data for its green certification. The American Institute of Architect's MasterSpec references MPI as its primary performance specification for paint. The website includes a Green Approved Product List.

scs logoScientific Certification Systems (SCS)
  The SCS environmental division certifies a wide variety of claims related to environmental achievement in the product manufacturing and natural resource extraction sectors. Specific product attributes, such as recycled content and biodegradability, are certified under the Environmental Claims Certification program. SCS also certifies broader claims of environmentally preferability, considering the full product life-cycle.

Life-cycle assessment tools

Life-cycle analysis (LCA) helps decisionmakers realistically assess the cost of a product by taking into account the environmental impacts of extraction, transportation, manufacture, lifespan, maintenance and disposal. LCA is controversial because it is so difficult to quantify these issues accurately and compare them across product categories. The following links offer important assessment tools, but purchasing decisions should not be based solely on the analysis of any one model or source of information.

The Athena Institute offers the only tools in North America for the life cycle assessment of whole buildings and assemblies:

  • athena logoThe ATHENA® Impact Estimator for Buildings allows users to evaluate whole buildings and assemblies based on internationally recognized LCA methodology. Using Athena's widely-acclaimed databases, the Estimator simulates over 1,000 different assembly combinations and is capable of modeling 95% of the building stock in North America.
  • athena logoThe ATHENA® EcoCalculator for Assemblies provides instant LCA results for more than 400 common building assemblies. Developed in association with the University of Minnesota's Center for Sustainable Building Research, the tool was commissioned by the Green Building Initiative™ (GBI) for use with the Green Globes™ environmental assessment and rating system. Because of its value as an indicator of climate change impacts, GBI supported creation of a generic version for use by the entire sustainable design community.
