Section 8 of the Standard includes an addendum on building Operations and Maintenance (O&M). The acceptance contaminant level criterion for parking garages is recommended in ASHRAE 2007 Handbook. The standard defines these components of energy use as regulated. Mechanical ventilation (MV) can be an answer; however, it can consume so much energy. Pure earth atmosphere, at 70°F with 50% relative humidity and devoid of smoke particles, mold spores, air-bourne pathogens, plant pollen, respirable dust and with oxygen and carbon dioxide levels that remain constant despite our breathing - would be ideal, but terribly impractical. a In using this table, the outdoor air is assumed to be acceptable. The most serious is the emission of high levels of carbon monoxide (CO) by cars within the parking garages. This would more than double the rate as required by our national standard SWKI VA 103-01. For larger buildings and garages it is common to use outlet air from the ventilation systems in the surrounding buildings as fresh make-up air to the garages. a) All sub floor and below grade work areas shall be continuously ventilated at a rate of not less. Unfortunately, this book can't be printed from the OpenBook.
