Occupational Safety and Health Administration (OSHA)

OSHA Laws & Regulations

OSH Act of 1970

Indoor Air Facts No. 4: Sick Building Syndrome

US Environmental Protection Agency (EPA)

The term "sick building syndrome" (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.

OSHA Technical Manual Section III: Chapter 2

Occupational Safety and Health Administration (OSHA)

Modern office buildings are generally considered safe and healthful working environments. However, energy conservation measures instituted during the early 1970's have minimized the infiltration of outside air and contributed to the buildup of indoor air contaminants.

Carbon Monoxide Poisoning

Occupational Safety and Health Administration (OSHA)

Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas. Although it has no detectable odor, CO is often mixed with other gases that do have an odor.

Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers

Environmental Health Perspectives (EHP)

The indoor built environment plays a critical role in our overall well-being, both due to the amount of time we spend indoors (~90%) and the ability of buildings to positively or negatively influence our health.

New Report Links Office Design with Staff Health and Productivity

Green Building Council (GBC)

This report from WorldGBC puts forward the best and latest information on the building design features that are known to have positive impacts on the health, wellbeing and productivity of office occupants, and points to financial implications.

School Buildings and Student Success

Harvard School of Public Health

In this report, the Healthy Buildings team at Harvard Chan School illuminates how the school building influences the student’s health, thinking and performance.

Healthy Housing Reference Manual
