Greenline® is a unique professional design service developed by Pizzo & Associates, Ltd. It redefines a well established professional design review process that is typically referred to as “redlining”. A redline drawing is an intermediate Engineering, Architectural, and/or Landscape Design drawing/document that shows revisions or corrections to a previous drawing and is used throughout the design process as the drawing(s) is refined. The term “redline” literally comes from the red inked pen typically used to amend the drawing(s) by hand during review by the lead designer. A Greenline® drawing is a review of an intermediate design drawing in order to show revisions or corrections that specifically implement and/or improve overall sustainability of a product design, process design, site design and/or building design. Greenline® review drawings will utilize a green inked pen to amend the drawing(s) by hand throughout the design process.
