Projects that wish to install room air conditioners must meet all of the following:
• They should follow the performance approach in EA. This is because room air conditioner units generally do not meet the efficiency requirements under prerequisite EA 6.1,
• The blower-door tests must be done after installation of the room air conditioners, AND
• Projects may not procure or offer options for air conditioner units that fail the prerequisites even if they are not installed. In other words, projects cannot get around requirements by not installing the air conditioner units until after certification.
