Wood construction offers distinct design options typically not found in a single structural material. It is inexpensive, readily available, easy to work with, strong and adaptable. The economic, environmental and energy-efficiency advantages account for more buildings being constructed of wood than any other structural material. The Heights and Areas (H&A) Calculator is a joint effort of the American Wood Council and WoodWorks – The Wood Products Council. It provides users with an app-based approach to calculating maximum heights and areas for buildings of various occupancies and fire protection based on 2009 to 2021 editions of the International Code Council’s International Building Code® (IBC®) provisions. Input a given building geometry, site conditions (e.g., open frontage), type of construction and occupancy, and allowable heights and areas can be determined. This H&A Calculator is not meant to be a replacement for the IBC and does not encompass all of its design options. The IBC should always be consulted for final construction type determination, in addition to state and local amendments to the IBC that may apply.
