BDwin analyses Infiltec blower door data and estimates building air infiltration, flow rate, and leakage area. Data from the DM4 micromanometer can be automatically entered into the program. BDwin works with all Infiltec air leakage measurement systems including E3 blower doors, stacked E3 blower doors, plus G54 and E36 large mobile fans. Both technical reports and customer reports can be printed.

BDwin FEATURES:

• Standard Calculations:

  Calculations include measurement standards EN 13829, TM-23, ASTM E779-03 & CGSB-149.1-2002.

• Choice of Units:

  You can switch between 1) USA units of in.wc & cfm, 2) mixed units of Pascals and cfm, and 3) Metric units of Pascals and m3/h.

• Choice of Reports:

  You can select between a technical report showing all of the standard calculations, or a customer friendly report that is easy for a non technical person to understand. Both reports can be previewed before printing.

• System Requirements:

  You can use BDwin with Windows 98, XP and Vista. You can enter data automatically from your DM4 micro-manometer. This requires a DB9 M/F serial cable if your PC has a free COM port. You can also connect to a USB port by using a serial-USB converter, if your PC has no free COM ports.
