Block load vs room-by-room
SECTION 04One load for the whole house
A single whole-building load — quick, and sometimes enough for equipment sizing alone. But it can’t tell you the airflow each room needs.
A load for every room
Loads calculated room by room, so ducts can be sized to deliver the right airflow everywhere. Manual D duct design requires it — so every report we prepare is room-by-room.
