6. Supply and return registers, if installed at the time of the test, shall be fully open.
7. If an attic is both air sealed and insulated at the roof deck, interior access doors and hatches between the conditioned space
volume and the attic shall be opened during the test and the volume of the attic shall be added to the conditioned space
volume for purposes of reporting an infiltration volume and calculating the air leakage of the home.

This application has glass areas that produce large heat gains for part of the day. Variable air volume devices
are required to overcome spikes in solar gain for one or more rooms. Install a zoned system or provide zone
control for problem rooms. Single speed equipment may not be suitable for the application.
