Sustainable Design

CEL Gruen is a consulting engineering group focused on integrated sustainable and renewable design, energy simulation, and LEED™ consulting. We firmly believe that good engineering is “green”. It is our objective to bring the appropriate sustainable solutions to each of our projects.

Specializing in the application of sustainable technologies, the Gruen team integrates the analysis of design options into the earliest phases of conceptual design. Early simulation of building energy performance allows systems to be compared and appropriately evaluated.
