![]() ![]() ![]() The lack of such knowledge, theory, and practice is an impediment to developing the necessary y professional design took and practices to address effectively indoor environmental quality and energy conservation issues. There is a need for a usefit1 general body of knowledge, theory, and practice regarding building-environment-occupant interactions. Based on this table, the minimum ventilation rate required to be delivered to the breathing zone (minimum amount of outdoor air) is 0.48 cfm/ft.sup.2 (2.4. The occupancy types where this is allowed are most of those with an area outdoor air rate of 0.06 cfm/ft2 (0.3 L/sm2). There is inadequate dissemination of building science research results to design professionals. 2.1, Minimum Ventilation Rates in Breathing Zone. However, the majority of design professionals have little or no awareness of indoor air quality considerateness. private offices), simply assign a floor area to each isolation zone and prorate the minimum ventilation area. In addition, changes that limit the chemical contamination of building air during the construction process and during occupancy of buildings are also occurring some of these changes are specified or controlled by design professionals. If all zones are of the same occupancy type (e.g. ![]() These changes include improvements in site planning and design overall building &sign ventilation and climate control systems and materials selection and specifications. The first two are similar to the corresponding MC18 values for, but use just the area-based minimum ventilation rate, rather than the overall 62.1 requirement. In recent years, some building design professionals have become more aware of the indoor air quality concerns of Owners and occupants and as a result, they have made some important changes to improve i n d m air quality and climate. ![]()
