We spend a lot of time indoors, whether that’s in residential or commercial/institutional settings. Exposure to indoor pollutants, some of which infiltrate from outside, can have adverse health impacts. Rather than treating indoor and outdoor pollution as two separate public health concerns, ROCIS sees them as closely related. That’s why we work to empower our stakeholders—citizens, leaders, nonprofits, schools, designers, and contractors—to respond effectively to this environmental and health concern and reduce exposure to air pollutants, especially airborne particles.

These are the core principles that guide our work:


Situations in which outdoor air is a significant threat to health indoors are of high concern.


Children and people with respiratory health issues are particularly susceptible to air pollution.


Continued research is needed to clarify health impacts, particularly interactive effects, of environmental sources of pollution.


Source control is the ideal method of managing health concerns from all pollutants.


Due to variations in weather, season, space, and time, identifying the source of outdoor pollutants can prove difficult.


Accurate and inexpensive sensors, when available, have a strategic role to play in measuring indoor pollutant levels and the impact of interventions.


Low-income families often deal with substandard housing, proximity to pollutant sources, and unaffordable mitigation measures.


In-home monitoring should be accessible to all, either through equipment loans or community-based projects.


Systems to reduce pollution exposure may have an energy cost but can also be an integral part of a comprehensive energy use reduction effort.


There is a critical need to demonstrate and disseminate mitigation solutions, incorporating continual improvement to assess efficacy and refine guidance.


Since 2014, the ROCIS team has been working to reduce the impact of outdoor contaminants in indoor spaces. With expertise in indoor air quality, monitoring, energy performance, public health, behavioral and technical interventions, and data analytics, our team members have delivered presentations, webinars, and white papers on air quality, monitoring, and interventions to reduce exposure. Through initiatives like the Low Cost Monitoring Project (LCMP) and the Clairton Air Filter Project, we’ve put that knowledge into practice. We have also developed numerous tools to help residents visualize and understand the air quality in the places they live, work, and learn.

We’re excited to continue this work well into the future.
