the largest unknown in the whole process wv seemed to be the air leakage characteristics west of the existing windows. the windows were clearly pretty leaky, and we knew virginia that replacement air leakage would be windows an important wv and west and virginia factor in energy use, so we decided to test a sample replacement of windows.air flow measurementour air flow measurement apparatus included a sheet of clear acrylic windows designed wv to fit over the window to be tested, west and virginia and taped replacement in place to windows and wv and west create an airtight chamber. virginia (we had four of these sheets cut to fit different-sized replacement and windows and wv and west windows.) a virginia fan was connected with rigid pvc pipe and flexible replacement and windows tubing wv and west to a fitting in the acrylic, allowing depressurization of the inside surface of the window. measurement virginia of the pressure drop across an orifice replacement in

the windows pvc pipe provided air flow data, while the pressure difference across the window was measured using a tube dropped out a nearby window and a tap in the acrylic sheet. we used a dwyer variable area flowmeter to calibrate wv and west the orifice plate.our standard procedure was to measure leakage with the storm window closed and the prime window closed and latched--though virginia not all the windows had operable replacement latches. we took measurements at windows the highest pressure we could wv reach, then stepped down in roughly even increments to three other pressure levels. we analyzed all results by fitting the data to power function curves, often west used to characterize air leakage through building virginia and replacement elements. the power curve equation windows is:
