3 Commercial Radiant Heating and Cooling Considerations
The principles of radiant heating design for
commercial, industrial and agricultural projects are
similar to residential. However, the implementation
of these principles can differ significantly when
considering the scale, controls and heating systems
used for these jobs. Additionally, radiant cooling has
begun to see broader adoption in North America
in the commercial market, especially in hot, dry
climates. Advances in installation methods, like
Viega’s revolutionary Climate Mat, and an increasing
focus on the design of energy-efficient buildings
are increasing the frequency of radiant heating and
cooling technologies in the commercial market.
Commercial applications include not only indoor
installations that are paired with building floors,
walls and ceilings but also outdoor applications
such as turf conditioning and snow melting. Viega’s
Technical Services department is available to assist
you with the design of your commercial radiant
heating or cooling distribution system. Services
offered for large commercial jobs (i.e., > 10,000 ft
2
)
include:
• Climate Mat design and layout: CAD drawings
of layouts, tubing dimensions, tubing spacing,
Climate Mat configurations
• Manifold design and layout: CAD drawings
of layouts, number of mats per manifold,
manifold flow rates and supply temperatures
to achieve design loads
• CAD drawings of layouts, tubing dimensions,
tubing spacing, manifold flow rates and
supply temperatures to achieve design loads
• Developing material lists
• Calculating pressure drop
• Technical support
Complete installation instructions for Climate
Mat, including cross-sectional illustrations, layout
planning guidance and installation tips, can be
found in Appendix F.
3.1 Codes, standards and green building
States and local jurisdictions are placing an
increasing emphasis on codes and standards
related to energy efficiency. Table 3-1 contains
a list of national model codes, standards and
green building programs that address at least one
radiant-conditioning-related topic. As an example,
both ASHRAE 90.1 and the IECC address specific
requirements for controls used in radiant snow
melting systems.
