An indoor air quality commissioning program has been developed and is being implemented in a new office building in Rockville, Maryland. New buildings can have an increased potential for indoor air quality (IAQ) problems due to new building materials and deficiencies in mechanical ventilation system operation during construction and initial occupancy. This IAQ commissioning effort is being implemented to reduce the potential for such problems in this building. This commissioning program consists of three tasks: (1) evaluate the mechanical ventilation system design; (2) develop a set of criteria that will be used to evaluate IAQ in the building, and (3) measure various environmental parameters for comparison with the criteria developed in Task 2. Tasks 1 and 2 have been completed and Task 3 is in progress. The evaluation of the mechanical ventilation system design was based on the recommendations of ASHRAE Standard 62-1989 and the 1987 BOCA mechanical code. The design evaluation showed that the system ventilation rates were consistent with the recommendations of the ASHRAE standard and the requirements of the BOCA code. The IAQ criteria developed in Task 2 address ventilation system performance, indoor pollutant levels, and thermal comfort. These criteria are based on appropriate standards and guidelines and on the results of previous IAQ research. Task 3 consists of the measurement of these IAQ parameters in three phases of building construction: after completion of interior buildout, after the installation of the systems furniture, and roughly one month after occupancy. The first phase of Task 3 is complete and the results indicate compliance with the IAQ criteria prior to installation of the systems furniture.
