New Construction and Indoor Air Quality
Construction activities have a definite effect on IAQ during occupancy. If the duct work of the construciton site becomes contaminated with water, construction dust, or debris prior to installation, it can result in air quality problems that can be costly to correct at a later date.
Operating the HVAC systems to provide temporary heat or cooling during construction may also compromise IAQ if filtering is not properly applied and maintained. During the final phases of most construction projects, considerable dust can be generated by some of the finishing operations such as dry wall sanding and concrete floor leveling. This dust requires special considerations in terms of filtration that may not be addressed by the filters provided with the system for the design operating conditions.
