Building Science

At the intersection of energy efficiency and indoor air quality, ARI's Indoor Climate Research & Training (ICRT) group strives toward, studies, and teaches about indoor environments that are safe, healthy, comfortable, and efficiently maintained.



ARI performs sponsored research on residential building science topics to identify and quantify indoor air quality health hazards in the home and assesses the impact of energy-saving and ventilation retrofit activities on measured pollutants.

Current research into the health of occupants in buildings has led organizations to work to improve home conditions to help address asthma triggers, reduce risk of damp spaces, and reduce exposure to carbon monoxide and other health hazards such as VOCs, radon, and particulate matter through understanding and evaluating building tightness, airflows and ventilation, heating and cooling systems, contaminant migration, and healthy home conditions.


  • ICRT advances the understanding of building science in the fields of residential ventilation and indoor air quality in single-family and multi-family units.
  • ICRT is working with the Gas Technology Institute and Midwest Energy Efficiency Alliance to study building energy efficiency and air-flow management.

Building Science & Health

  • ICRT researchers at ARI work with the National Center for Healthy Housing and local practitioners to study the linkage between residential building air quality and health to find ways to retrofit homes that reduce illness rates.
  • ICRT incorporates research results into its training programs for building science practitioners to better identify potential home health hazards.
  • The ICRT the “Customizable Sensor Packages for Healthy Homes” project team convened a stakeholder workshop to discuss the potential opportunities, uses, and needs of a customizable sensor system approach for indoor air quality measurements. In addition to the UIUC team, attendees represented broad city and state interests.

Building Science and Aging in Place

  • ICRT researchers at ARI are working on understanding and increasing awareness about Smart Home technologies that will help an aging population age at home partnering with UIUC Applied Health Sciences Human Factors lab & Eastern Illinois University professors.

Building Science & Policy

  • ICRT researchers at ARI are partnering with the Department of Economics at the University of Illinois at Urbana-Champaign to evaluate the effectiveness of contractor pay-for-performance type incentive to study the impact of compensation on air-sealing performance in the weatherization industry.


ICRT trains and certifies Illinois based energy assessors, quality control inspectors, and other associates from the local weatherization community action agencies to perform weatherization related work. 

ICRT is accredited by the Interstate Renewable Energy Council (IREC) to deliver quality building science training. ICRT is also a Building Performance Institute (BPI) qualified exam center for the Energy Auditor, Quality Control Inspector, and Healthy Homes Evaluator on-line and field exams.
