The 2010 NFPA 13: Installation of Sprinkler Systems is revised and updated with added criteria based on recent fire testing and studies performed by the Fire Protection Research Foundation. Chapter 20: Special Designs of Storage Protection presents requirements for the protection of three new special storage arrangements, including carton records storage with catwalk access, and high bay records storage. This edition also adopts the SEI/ASCE 7 approach for load calculations and introduces new zone-of-influence tables for Schedule 5 steel pipe, CPVC, and Type M copper tube. An important new method to calculate rack shelf area takes the placement of loads into consideration.

Flip through the 2021 IMC and find frequently used sections fast! You'll be surprised how easy it is to find what you are looking for. These tabs were created by industry experts who carefully identified the most referenced sections in the code.

Used to determine how much heating/cooling a home needs to stay cool and dry in the summer and warm in the winter. This load calculation process was developed by engineers in the heating and air conditioning industry and has been used for decades to accurately size heating and air-conditioning equipment. After completing this load calculation process, one can choose a properly sized piece of machinery to satisfy the load.

Compact and pocket-sized, this handy reference contains thousands of facts and figures relevant to pipefitters, steamfitters-anyone concerned with layout and installation of pipe.

The IPC provides minimum regulations for plumbing facilities and provides for the acceptance of new and innovative products, materials, and systems. In October 2019, the Code Council released an independent study comparing model plumbing codes. It found that over a 12-year period, counties using the IPC saved $38 billion in construction costs, emitted 1,000,000 fewer tons of carbon dioxide, saw an additional 166,000 jobs, and saved 880 million feet of pipe. On average, a single-family home could save up to $4,000 in labor, materials and overhead compared to that same home built to other codes. To learn more about the IPC’s impact on construction, the economy and the environment, read the full report at www.iccsafe.org/IPC.

Important changes in the 2021 IPC include:

Multiple-user toilet facilities to serve all genders are now permitted.
Two new methods for relining/rehabilitation of existing sewers are added.
Accommodations for mounted roof top solar panels over vent terminals is added.
CSA B805/ICC 805 Rainwater Harvesting Systems is allowed as an alternative design method.
Plumbing provisions from ICC A117.1-2017 Standard for Usable and Accessible Buildings and Facilities are now included.
