Fixed bug in summary sheet so that all systems are always displayed.Modified rounding and decimals displayed.Note added to Are you using default value for zone population to clarify default values should only be used if expected occupancy is unknown.Added column for Zone outdoor airflow provided to the 100% OA and corresponding column in the summary tab (zone outdoor airflow provided meets or exceeds Voz for all zones).In multiple zone sheet, changed Ep from user entry to calculated value. Using mass balance calculations, determine the minimum breathing-zone outdoor air ow rate necessary to meet the speci ed concentration limits for each contaminant-of-concern and mixture-of-concern 7.It includes outdoor intake air and recirculated air from that air-handling unit but does not include air transferred or air recirculated to the zone by other means. Use the following method to calculate the 1 inch depth filter face area required: Divide the design airflow rate (ft3/ min) for the filter grille/rack by. The increase of storey height will lead to a decline of pollutants in the breathing zone and the demand outdoor airflow. Updated Table 6-3 calculation for Ev in the multiple zone sheet to not exceed 1.0 when Max ZpFixed bug with default values for zone population in the single zone sheet.- v04 - Updated to include LEED v4.1 option zone listed in Section 3, and the calculation of Breathing Zone Outdoor Airflow in Section 6.2.2.Assumptions for occupancy categories are from ASHRAE 62.1-2010 (for LEED v4 projects) and ASHRAE 62.1-2007 (for LEED 2009 projects). The calculator accommodates all ventilation types (multiple zone, single-zone, 100% outside air) in one spreadsheet. ammonia concentration to 10 ppm at the breathing zone of the animals. The minimum outdoor airflow required to be supplied to each zone shall be determined as a function of occupancy clas-sification and space air. Basic research on the field of air flow in livestock. The Minimum Indoor Air Quality Performance Calculator can be used for projects using ASHRAE 62.1 to comply with LEED BD+C, ID+C and O+M EQ Prerequisite Minimum Indoor Air Quality Performance, EQ Credit Increased Ventilation, and EQ Credit Enhanced Indoor Air Quality Strategies, Option 2, Strategy B: Increased Ventilation, as well as LEED Homes and Multifamily Midrise EQ Prerequisite Ventilation. The required outdoor airflow rate shall be introduced directly into such spaces or into the occupied spaces from which the air is transferred or a combination of both.
