Why Green Buildings Matter More Than We Think

It’s no secret that designing and constructing high-performing, energy-efficient, sustainable buildings and interior spaces is more important today than ever before.  Green buildings lead to reduced environmental impact; healthy returns-on-investment for architects, designers, builders, owners, and product manufacturers; as well as substantial cost savings for end-users.

But in our haste to protect the planet, conserve natural resources, and promote clean outdoor air, one critical piece of the green building puzzle—and, arguably, the most important—is often overlooked: indoor air quality.

“The greatest irony of sustainable design and construction is that, often, the built environments we’re creating don’t sustain human health,” says Henning Bloech, executive director of the GREENGUARD Environmental Institute. “While sustaining earth’s natural resources is critical, we can’t lose sight of the underlying goal: keeping people healthy.”

What is Indoor Air Quality (IAQ)?

Indoor air quality refers to the quality of air inside built environments as it relates to human health: the better the IAQ, the healthier the air that people breathe.  Unfortunately, statistics consistently show that indoor air is two to five times more polluted than the air outside. Even worse, the air in newly constructed and/or renovated interior spaces can be up to 1,000 times more polluted than outdoor air. Why?  Because many of the synthetic products and materials we use to design and build these spaces emit a cocktail of volatile organic compounds (VOCs) and other pollutants into the air—things like potential carcinogens, reproductive toxins, odorants, and other irritants, Bloech says. 

Not surprisingly, research has linked poor IAQ to a number of health risks, including asthma and other respiratory ailments; headaches; eyes, nose, and throat irritation; and even cancer. This, in turn, leads to decreased productivity, lower academic performance, and increased absenteeism.

Why You Should Care

As architects, designers, builders, owners, and product manufacturers, you help shape and lead the green building and design industry. The built environments you help create and furnish today—whether they’re homes, schools, hospitals, community centers, or retail spaces—will have enormous health impacts on the people who occupy them tomorrow. 

Paradoxically, some of the world’s “greenest” buildings—those that meet strict environmental criteria for energy efficiency, site selection, water conservation, and material selection—fail to account for the quality of their indoor air.

“Sure, it’s a great thing when we create interior environments made from renewable resources,” Bloech says. “But, if the adhesives used to hold those renewable resources in place release toxic chemicals into the air, then the building we once thought was sustainable is actually doing more harm to its occupants than good. And that goes against everything green building and design stands for.”

To complicate matters, at the core of green building and design is energy efficiency: saving energy equals saving money equals saving the planet. Yet, the more airtight our built environments are, the more polluted the air inside them becomes: the chemicals that emit from indoor sources get trapped inside. “We may be harming our health without even realizing it,” Bloech says.

What We Don’t Know May Hurt Us

Four decades ago, you—the world’s leading architects, designers, builders, and manufacturers—helped make it possible to reduce human exposure to lead and asbestos in our built environments—even though these building materials were as commonplace (and as accepted) as hardwood flooring or carpeting. You acknowledged the harmful effects that these materials have on human health, and you acted. As a result, today, the levels of lead in children’s blood across every population are markedly lower.   

More recently, you also helped cut back on industry use of formaldehyde, a chemical that emits from common building materials, like engineered wood products or insulation, and is known to cause cancer. Thanks to your actions, today, fewer people are exposed to this hazardous chemical.

But science has shown that more than 12,000 other chemicals emit from the products we use or encounter every day. Many of them are known carcinogens, irritants, or developmental and reproductive toxins. Others we know very little or nothing about.  Experts warn that exposing ourselves to these unknown chemicals is like gambling with our health. 

“Until we learn more about these compounds and their potential impact on human health, it would be prudent to limit our exposure to them as much as possible,” says Marilyn Black, founder of the GREENGUARD Environmental Institute. “New chemicals are introduced into our environment every day. Do we really want to let ourselves and our children become research guinea pigs?”

How You Can Help Today

By doing your part to raise awareness about poor IAQ and its health impacts, you can help gain the political, economic, and social momentum needed to make doing your jobs easier and more cost-effective. You can help ensure strong returns-on-investment, healthy profits, and increased consumer demand. And you can help transform neighborhoods, communities, cities, nations, and human lives. 

“Economic growth, political viability, and social progress all share a common thread: human health,” says Black. “Once we recognize that human health is the cornerstone of green building and design, we can effect real, positive change on the world.”

GREENGUARD Awards $2,000 to “Green”
Start-Up Company Founded by College Students

The GREENGUARD Environmental Institute recently awarded $2,000 in prize money to “Waste to Watts (W2W): Solution-Based Recycling,” an Atlanta-based start-up company with a mission to end energy poverty in third-world countries and reduce environmentally hazardous electronic waste. 

GEI awarded the prize as part of the 2010 Georgia Tech Business Plan Competition, which promotes entrepreneurship among Georgia Tech students and alumni by encouraging them to launch cutting-edge, high-value businesses. GEI has proudly sponsored the GREENGUARD Sustainability Award for the past three years. 

Founded by two Georgia Tech seniors, a Duke University sophomore, and a Duke University alumnus, W2W  aims to repurpose electronic waste—like computer equipment and discarded lead acid batteries—to create an inexpensive, uninterruptible power supply (UPS) for developing nations. This is important because in developing nations, frequent power surges, daily blackouts, and other electricity failures damage the computers and medical equipment used in hospitals, which results in poor and unreliable health care. Moreover, dead lead acid batteries—which contain hazardous heavy metals—are often disposed of improperly and contribute significantly to environmental pollution.

W2W’s founders say they plan to use their prize money to help pay for a new Web site and the continued development of their prototype. 

Changes to California Emissions Test Method Prompt Changes in Product Manufacturing and Emissions Testing

The  California Department of Public Health, in collaboration with the GREENGUARD Environmental Institute and a group of product emission experts and government officials, have developed a revised version of the Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers(CA/DHS-EHLB/R-174), commonly referred to as CA 01350.The revised test method, dubbed version 1.1, incorporates several important changes, including the following stipulations:

  • Laboratories that follow this method to test products must implement a quality management system in accordance with ISO 17025.
  • Certification organizations that use this test method to certify products should operate in accordance with ISO Guide 65.
  • Effective immediately, stricter limits will be enforced regarding product selection.
  • Effective January 1, 2012, products must meet a more stringent formaldehyde emission requirement.

The development of version 2.0 of this test method will take place this year.  Issues likely to be addressed include:

  • Expanding the number of volatile organic compounds and other chemicals that the test method currently takes into account;
  • Including a TVOC limit to limit human exposure to unknown chemicals;
  • Updating the current model environments used to test emissions in commercial spaces.
  • Creating additional model environments to test emissions in a wider variety of interior spaces (e.g., healthcare facilities).

As part of its commitment to improving human health and quality of life, the GREENGUARD Environmental Institute will continue to advocate for the most stringent scientific test methodology possible to help protect indoor air quality.

GEI and NSF International to Develop National Health-Based Standard

GREENGUARD Environmental Institute (GEI) and NSF International have announced that they will jointly develop a health-based standard addressing chemical emissions from products. This comprehensive standard will streamline the various methods used in the marketplace to measure and limit chemical emissions. Following a transparent and inclusive process, GEI and NSF have brought together a diverse group of experts and stakeholders to develop the standard. 

The development procedure will comply with the American National Standard Institute’s (ANSI) Essential Requirements for adoption as an ANSI Standard. These requirements ensure that the standard is developed in an open and collaborative manner with participation by multiple stakeholders. A consensus committee helps develop and vote on the standard, while subject matter expert work groups provide guidance and scientific expertise. To round out the process, mandatory public comment periods allow individual stakeholders or organizations to offer input on drafts of the standard.

GEI and CHPS to Host Seminars on Improving
Health and Performance in Colorado Schools

For the second year in a row, the GREENGUARD Environmental Institute—in collaboration with the Collaborative for High Performance Schools (CHPS)—will sponsor a series of seminars on how U.S. schools can achieve energy efficiency, enhanced student performance, and improved student, staff and faculty health.
This year, the full-day seminars will focus on the Colorado CHPS Criteria (CO-CHPS), a new high performance assessment tool and set of sustainable design guidelines designed specifically for Colorado schools. The guidelines will reference GREENGUARD Children & SchoolsSM Certified products, which help earn points for indoor environmental quality (IEQ).

The seminar schedule is as follows:

  • Monday, April 26 in Grand Junction
  • Wednesday, April 28 in Colorado Springs
  • Thursday, April 29 in Denver

Sustainability News
ASHRAE 189.1

GREENGUARD Children & SchoolsSM Certified product manufacturers will benefit from a new “green” building standard that requires the use of low-emitting products in sustainable building design and construction. The new standard—dubbed ASHRAE 189.1—calls for minimal product emissions in indoor environments, and will be enforceable by federal, state, and local code officials.

ASHRAE 189.1 (short for ANSI/ASHRAE/USGBC/IES Standard 189.1) is an ANSI Standard that addresses many of the same issues as LEED: reduction of water, energy, and natural resource use; site sustainability; indoor environmental quality; and atmospheric impact. Unlike LEED, however, sustainable buildings meeting the AHSRAE 189.1 standard must fulfill all of its requirements; there is no cumulative “point” system.

The GREENGUARD Environmental Institute has been instrumental in the development of ASHRAE 189.1 through active participation in public comment and in-person meetings.

All GREENGUARD Children & Schools Certified products meet the ASHRAE 189.1 standard in the following categories:

  • Adhesives & Sealants
  • Paints & Coatings
  • Floor Covering Materials
  • Composite Wood, Wood Structural Panel & Agrifiber Products
  • Office Furniture Systems and Seating*
    *All GREENGUARD Indoor Air Quality Certified® products qualify, but at least half of them need to be GREENGUARD Children & Schools Certified.
  • Ceiling & Wall Systems (includes insulation, ceiling panels, gypsum, and wall coverings)
  • 8.5.2 a Flooring
  • 8.5.2 b Fabric
  • 8.5.2 c Wall Systems
  • 8.5.2 d Insulation
  • 8.5.2 e Adhesives & Sealants
  • 8.5.2 e Paints & Coatings
  • 8.5.2 f Cabinets*
    *All GREENGUARD Indoor Air Quality Certified products qualify, but at least half of them need to be GREENGUARD Children & Schools Certified.
  • 8.5.2 g Office Furniture Systems & Seating*
    *All GREENGUARD Indoor Air Quality Certified products qualify, but at least half of them need to be GREENGUARD Children & Schools Certified.

The GREENGUARD Environmental Institute is listed in the Informative Appendix of ASHRAE 189.1 as a resource for finding low-emitting products.

The GREENGUARD Environmental Institute is recognized across the world as a leading authority on indoor air quality. The list of organizations, specifications, and IAQ programs that use or reference GREENGUARD Certified programs is constantly growing. Here’s a look at a few new additions:

  • Unified Facilities Guide Specifications
  • These require GREENGUARD Certification of all furniture. The U.S. Army, U.S. Navy, U.S. Air Force, and NASA use this specification.
  • Connecticut Building Standard Guidelines
  • These cite GREENGUARD Children & Schools Certification as a way to identify low-emitting adhesives and sealants; paints and coatings; ceiling and wall systems; wall coverings; and flooring.  In addition, the guidelines state that only GREENGUARD Children & Schools Certified furniture may be used in schools.
  • ASHRAE 189.1 Section 8.4.2 Materials and 8.5.2 Materials.

Ask the Expert
Can Weatherized Homes Suffer From Poor Indoor Air Quality?

The results of a 2005 mail survey indicated that many California homeowners never use their windows for ventilation. This led to concerns that residential building codes—which allow windows as an alternative to a mechanical system for providing the required outdoor air ventilation—may result in homes that suffer from inadequate ventilation for controlling indoor air contaminants.

In response to these concerns, Indoor Environmental Engineering (IEE) conducted a two-year-long, multi-season study of ventilation and indoor air quality in 108 new single-family detached homes in California.  The results of IEE’s study were unsettling: not only did they confirm that many homeowners never open their windows, they also revealed that the homes were quite airtight: 67-percent of the homes had outdoor air exchange rates below the 2006 California Building Code requirement of 0.35 air changes per hour.  Consequently, indoor airborne contaminant levels were elevated and exceeded recommended exposure guidelines.

The air contaminant that most frequently exceeded exposure guidelines was formaldehyde, a known carcinogen and human irritant.  Ninety-eight percent of the homes studied exceeded the chronic irritation guideline; 28-percent exceeded the acute irritation guideline; and 100-percent exceeded California’s No Significant Risk Level (NSRL) for cancer. Experts believe that formaldehyde emissions in homes come largely from composite wood products (e.g., particle board, MDF, OSB, and plywood), which are typically made with inexpensive formaldehyde-based resins and are used in both home construction materials and home furnishings.  Other indoor air contaminants that exceeded recommended cancer exposure guidelines included acetaldehyde, benzene, chloroform, 1,4-dichlorobenzene, naphthalene, and tetrachloroethene.

To make matters worse, homes with simple outdoor air connections to the forced air heating/cooling systems provided little outdoor air ventilation, and thus did not significantly reduce the levels of indoor air contaminants.  This is due to low outdoor air intake flow rates and low fractional on-times.  Homes with continuously operated heat recovery ventilators (HRVs) performed well.

As it turns out, the results of the IEE study prompted two important changes to California building codes and environmental regulations. In April 2007, the California Air Resources Board (CARB) adopted an airborne toxics control measure (ATCM) to reduce formaldehyde emissions from composite wood products, including hardwood plywood (HWPW), particleboard (PB), and medium density fiberboard (MDF), as well as furniture and other finished products made with composite wood.  And in 2008, the California Building Code began requiring all residences to install a mechanical outdoor air ventilation system.

So, can tight-envelope, weatherized homes suffer from poor indoor air quality—even if they’re newly-constructed?  The answer is a resounding yes.  But the good news is that the issue is manageable: to limit exposure to airborne indoor contaminants, choose low-emitting building materials in conjunction with energy-efficient mechanical ventilation systems, and limit the number of indoor formaldehyde sources.       —Francis (Bud) J.
