HVAC Systems Survey

Michaels Engineering will also conduct a visual survey of heating, ventilating and air-conditioning (HVAC) systems. If the configuration of ventilating systems permits, we will estimate the quantity of outdoor air being provided to the building under worst case conditions. Where accessible, we will check the condition of filters, heat exchangers and condensate drains. The impact of energy management strategies will be considered as part of the HVAC survey.

Flow visualization techniques will be used to determine the direction of air movement in special use areas of the school. Of particular concern are those areas where air contaminants are routinely generated: wood or metal shops, kitchens, mechanical equipment rooms, locker rooms, or areas where cleaning supplies are stored. The purpose of this step is to assure that proper balancing of ventilating systems results in the flow of air from "cleaner" to "dirtier" areas of the building.
