RED Calc Free

v1.0, Legacy Tool

Summary: Calculates the hourly infiltration for a selected date range (one day to one year) and the resulting sensible load for heating and/or cooling systems. Daily average infiltration rates (stack, wind, and combined) and daily infiltration load on heating and cooling systems are displayed on separate charts for the selected date range. Additionally, balanced or unbalanced ventilation can be combined with infiltration with the results displayed in a table and on a chart, along with the resulting additional load on the heating and/or cooling system. The tool combines the powerful AIM-2 infiltration model with typical meteorological year data (TMY3 for the US and CWEC for Canada) for over one thousand weather locations in North America). See Tool GuideClick on any input or result label for help.
