Canada’s Journal of Commerce says that modular housing can qualify for LEED (Leadership in Energy and Environmental Design) certification just as much as stick-built construction.  Tom Hardiman, executive director of the Modular Building Institute (MBI), says, “Any project that can be site built can be more efficiently built off site.”  Overspray and material off-gassing are more controlled, resulting in better indoor environmental quality.  The structural insulated panels with R-values up to R-45 realize a 50 percent better energy savings over a wood-frame construction.  Mike Huggins, of Burrows Huggins Architects, stacked 50 recycled 2010 Olympic Village modular units, each 12 by 50 feet, to create a 100-room LEED Silver facility.  The hydronic heating system comes from a mat of capillary tubes set into the plaster between the ceiling joists to make the ceiling a large radiant panel.  Says Huggins, “The modules are easily recycled, which may not result in LEED points, but supports sustainability.”
