Sustainability & LEED
Most projects in the public sector are giving serious consideration to LEED certification, so discussions about sustainability are often woven into our work.
Like most structural firms, LHC is accustomed to evaluating structural systems for recycled content, local material content and overall efficiency. We provide mainstream green specifications, but can also push the envelope to maximize green provisions or even pursue LEED innovation credits.
Our real value, however, is embedded in our work style and approach to projects. It is a core part of our process to work closely with our design partners to develop customized and integrated building solutions.
It is natural for us to participate in sustainable initiatives that indirectly affect the structural design. These include such items as green roofs, solar arrays, storm water collection systems, heat recovery and other mechanical systems, and sophisticated building envelope solutions.
All of these have a significant impact on the building framing and we are accustomed to assessing and implementing solutions that incorporate these systems.
He has conducted research and written specifications for sustainable concrete, specifically the use of recycled concrete as coarse aggregate and high volume fly ash and ground granulated blast furnace slag (GGBFS) substitution for cement in ready mix concrete.
These are cutting edge ideas that have yet to gain traction in U.S. construction markets. Mr. Stevenson was the lead structural engineer for Searle Building Q in Skokie, IL., the first LEED Gold lab building.
