Featuring the very latest industry standards in material design, the 2015 INTERNATIONAL BUILDING CODE? LOOSE LEAF version offers up-to-date, comprehensive insight into the regulations surrounding the design and installation of building systems. It provides valuable structural, fire-, and life- safety provisions that cover means of egress, interior finish requirements, roofs, seismic engineering, innovative construction technology, and occupancy classifications for all types of buildings except those which are detached one and two family homes and townhouses not more than 3 stories high. New code sections have been added to the 2015 IBC? that cover rooftop mounted photovoltaic solar panels and all the content in the book is developed in the context of the broad-based principles that facilitate the use of new materials and building designs. The updates to this code make it an essential reference guide for anyone seeking a strong working knowledge of building systems.
