The award was presented to PPI-member company Uponor. The Society Orlando is a two-tower, 1.5-million-square-foot, mixed-use, high-rise project in the downtown Orlando, Florida Central Business District.

PPI MS-7 includes detailed specifications for four plastic piping materials which have been proven in ground-source heat exchange systems: HDPE, PE-RT, PEX, and PP (PP-R and PP-RCT).

MAB serves as an independent, non-commercial adviser to the Municipal & Industrial Division of the Plastics Pipe Institute (PPI), and is made up of industry experts who volunteer their time and expertise to improve the design, installation and operation of municipal high-density polyethylene (HDPE) water piping systems.

The document provides the rationale, data and formulas for determining the proper wall thickness for a fused, highly ductile, flexible HDPE water main in a seismically sensitive area, subjected to an induced lateral spread.

The latest updates in Version 3.0 of the calculator include the addition of more than 50 new pipe sizes, methanol as a fluid choice for geothermal designs, sodium chloride and calcium chloride brine solutions as fluid choices for chilled water, and the new Static Water Column Pressure function. 

Over the past 60 years, plastic piping materials have evolved from a new alternative to the material of choice for building and construction applications such as hot- and cold-water plumbing distribution, fire protection and mechanical systems like hydronics and chilled water.
