PCD Engineering Services provides indoor environmental quality assessment, design, commissioning, management and maintenance, and problem mitigation. We believe the sooner high performance goals – including those intended to ensure superior indoor air quality – are considered in the design process, the easier and less costly they are to incorporate. We provide education and training to establish effective operation and maintenance procedures that sustain superior indoor air quality throughout the life of the building.
Surveys indicate that comfort problems are common in many U.S. commercial buildings. A recent Occupational and Safety survey noted that 20 to 30 percent of commercial building suffer from indoor air quality problems. Building occupants suffer from symptoms ranging from headache and fatigue to severe allergic reactions. The National Institute of Occupational Safety and Health surveyed 350 buildings with deficient indoor air quality and found that more than 1/2 of the complaints stemmed from HVAC systems that were not maintained properly. Poor indoor air quality results in decreased productivity rates, health issues for building occupants, and liability for building owners.
According to the Department of Education’s National Center for Education Statistics in 1999, 43% of American schools–about 33,800–reported at least one unsatisfactory environmental condition. Approximately 20% reported unsatisfactory indoor air quality which can impact the comfort, health and performance of students and staff.
Our indoor environmental quality services encompass such factors as:
- Maintenance of acceptable temperature and relative humidity
- Control of airborne contaminants
- Distribution of adequate ventilation air
- Lighting and daylighting
- Building acoustics
