Air Contaminants

Air contaminants are any substances in the air, particulate or gaseous, which pollute the air and make it hazardous to human health. Good indoor air quality management techniques seek to reduce the amount of contaminants in the air and protect the health of vulnerable building occupants.

Indoor Air Quality (IAQ)

Indoor Air Quality (IAQ) refers to the state of the air within a space. A space with good indoor air quality is one that is low in toxins, contaminants and odors. Good air quality possible when spaces are well ventilated (with outside air) and protected from pollutants brought into the space or by pollutants off-gassed within the space. Strategies used to create good IAQ include bringing in 100% outside air, maintaining appropriate exhaust systems, complying with ASHRAE Standard 62.1, utilizing high efficiency MERV filters in the heating ventilation and air conditioning (HVAC) system, installing walk-off mats at entryways, prohibiting smoking with the space and near operable windows and air intakes, providing indoor plants, and using only low-emitting / non-toxic materials and green housekeeping products.

The U.S. generated approximately 251 million tons of municipal solid waste (MSW) in 2012. Almost 87 million tons were recycled and composted, which represents a 34.5% recycling rate. Solid waste generated per capita is the lowest since the 1980s. This is a 3 percent increase in the tons recycled.

Sense of Place

Skylight and Sculpture

What makes a workplace special? What fosters a sense of attachment, engagement and identity? These are the kinds of questions that underlie the sense of place. The workplace is increasingly seen as a “brand” that conveys not only a place, but also the mission and values of the organization. The GSA workplace program combines branding and sense of place with sustainable approaches to create special places imbued with meaning and purpose.
