ASHRAE also suggests intermittent exhaust capacities for kitchens and bathroom exhaust to help control pollutant levels and moisture in those rooms. The spreadsheets provide the set of standard operating conditionsincluding hourly and monthly profiles for occupancy, lighting, appliances, and miscellaneous electric.

Use the below sheet (very simple excel sheet) to add the duct run, friction factor, pressure drop in all accessories and repeat the same for the return air duct (or Fresh air duct whichever is. as the minimum ventilation rates in residential buildings in order to provide IAQ that is acceptable to human occupants and that minimizes adverse health effects. The Building America Analysis Spreadsheets are companions to the House Simulation Protocols and can assist with many of the calculations and look-up tables found in the report. ASHRAE (formerly called the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends (in its Standard 62.2-2016, "Ventilation and Acceptable Indoor Air Quality in Residential Buildings") that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per person. The rate at which outdoor air replaces indoor air is described as the air exchange rate. Increasing the amount of outdoor air coming into the building helps to control pollutant levels, odors, temperature, humidity and other factors that can impact the health and comfort of building occupants. Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.
