2012 Uniform Mechanical Code,

The 2012 edition of the Uniform Mechanical Code (UMC©) represents the most current approaches in the mechanical field.  It is the fourth edition developed under the ANSI Consensus process is designated as an American National Standards by the American National Standards Institute (ANSI). Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, labor, manufacturers, research/standards/ testing laboratories, special experts and users. The UMC provides complete requirements for the installation and maintenance of heating, ventilating, cooling and refrigeration systems, while at the same time allowing latitude for innovations and new technologies.

Key changes to the 2012 UMC include new provisions for piping, tubing, balancing, louvers, ductwork, safety requirements for refrigeration machinery rooms and an alternative to calculate ventilation efficiency. Significant improvements in Chapter 3 include provisions for a heating or cooling air system that provides specific requirements with return air, outside air or both, which are designed to replace required ventilation arranged to discharge into a conditioned space not less than the outside air specified in Chapter 4. Standards are referenced for louvers and their locations where installed in hurricane prone regions by providing minimum performance ratings for water rejection abilities and high-velocity wind conditions. Provisions added in Chapter 4 offer an alternative for calculating ventilation efficiency through ASHRAE Standard 62.1 and updating minimum ventilation rates in breathing zones based on occupancy.
