The building must maintain 50% or more of the following five existing building elements, based on their total combined surface area. A. Exterior of above -grade and below -grade exterior walls B. Interior of above -grade and below -grade exterior walls C. Floors D. Ceilings E. Roof decks as defined by the Building Code of New York State (exterior surface area) The 50% threshold relates to the total combined surface area of all listed building elements. Any individual elements, or portions thereof, may be replaced, as long as the total surface area of all the unaltered elements is at least 50% of the starting (pre - construction) total surface area of the elements. 144-C402.5.4.2 Any insulation may be altered to the extent allowed by the ECCCNYS in effect at the time of building permit application.

All requirements are included in 144-C402.5.4.1 and 144-C402.5.4.2, above. The simplified diagrams in Figure 144-C402.5.4.3 highlight which surface areas should be counted for two example buildings.

The exterior surface area of the roof deck is counted, and the ceiling of the second story is counted; note that the floor of the attic is not counted. The diagram on the right shows a two-story commercial building with a flat roof and no basement or attic. Insulation is between the roof deck and the ceiling of the second story.
