Global Material Database.
New Popup Material Selection Windows: Allows you to quickly select from the large selection of available materials.
More Options for Each Glass.
More Precise Duct Load Factors.
Calculation Method Option: Automatically determines the optimum method to use for compliance with Manual J's recommendations for system and room level load calculation methods (Average or Peak method).
Adequate Exposure Diversity Test Graphical Report.
Psychrometric Chart Graphical Report.
Winter Humidification Load: Allows you to specify an indoor relative humidity in the winter in order to calculate the required gallons per day of water to be added, as well as the sensible loss due to the device.
Hot Water Piping Load: Lets you enter the characteristics of the hot water distribution pipe in order to calculate its sensible loss.
Blower Power Sensible Gain: When the cooling equipment's rated capacity does not account for the heat gain due to the blower motor and fan, this input allows you to directly enter the wattage of the blower as a supply side load.
Adequate Exposure Diversity Check: An hour-by-hour calculation is done on the glass sensible gain to determine if the system meets the criteria for Manual J's Adequate Exposure Diversity test.
