New construction is simple compared to an addition or remodel project. The insulation values are usually consistent in a new Building and Houses, but in an older Building and home, it may vary from room to room. It is not sufficient to merely supply the additional room(s) with the calculated amount of heat, as it may throw the existing rooms out of balance. Sometimes it is necessary to supply the new room with an incorrect amount to keep it proportional to the rest of the house. In severe situations, the newer area may need to be heated as a separate zone.In any case, a heat loss/gain should be performed on the existing rooms as well, and the existing system should be evaluated to determine how well it conforms to the calculated requirements. A new heat loss will also tell you if the existing heating system can accommodate the additional load requirements of the addition.
Also keep in mind that the rooms adjacent to the addition have lost exposure to the outside and will need less heat.
These same conditions also apply to remodeling projects, where the addition or removal of windows can seriously affect the room's heating needs as will adding doors or raising ceilings.
