Span and many of our key suppliers are members of the United States Green Building Council
(USGBC), and we are able to assist owners in gaining LEED (Leadership in Energy Efficient
Design) certification. We believe in these organizations’ principles not only because they make good
environmental sense, but in many cases, good long-term economic sense as well.
Much of our construction is done with steel – a highly recycled commodity, produced using high-
efficiency mini-mills in close proximity to our projects. This not only requires less energy, but less
transportation, for reduced carbon footprinting.
We save significant amounts of steel by working with our metal building suppliers to custom-engineer
primary structural sections for our projects.
For each project, we propose a variety of solutions that allow the project team to evaluate capital,
maintenance and operating costs for both the building envelope and the heating, cooling and lighting
systems. These solutions may range from increased insulation to a “Cool Roof” system to low emissivity
blankets, in order to maximize efficiency and minimize operating costs.
