Sustainable Investment Group’s (SIG) green building and LEED consulting services strive to inspire sustainable development as a means of adding property value and increasing environmental awareness, while also fostering healthy, livable indoor conditions for building occupants. Over the years, we have grown a team of talented, creative, and passionate project managers and analysts who make reaching your green building goals as easy and efficient as possible. Collectively our team has worked on over 400 LEED projects across the nation. On this journey, SIG consistently demonstrated excellence in administering LEED certification for new and existing buildings. This sustained performance earns our consulting team LEED Proven Provider designation by the Green Business Certification Inc.— a mark of approval for streamlining the LEED project review process.
The founding partners and principals of SIG hold decades of experience in the fields of architecture, engineering, construction, and business management. This diverse background ensures that every angle of design, construction, and operations is optimized for people, the planet, and your profit. In this way, we value triple bottom line solutions to balance the natural and built environments with your economic success. Our qualified team includes LEED Accredited Professionals (LEED AP), Professional Engineers (PE), Commissioning Authorities (CxA), Certified Energy Managers (CEM), and AIA Registered Architects (RA).

“SIG handled all the paperwork and submissions which took a tremendous load off the Owner and architectural team…but it was the input from SIG that pushed the project up several levels to Gold. They were energetically pro-active, flexible, and creative in what was a non-conventional approach to LEED certification. I welcome the opportunity to work with them again.”

“We hired SIG to prepare a LEED Gap Analysis & Feasibility Study on our 52-story office building in downtown Manhattan in 2014, which they did an excellent job on. Then, our ownership required three bids for LEED Consulting + Related Engineering Services. SIG had the best value + experience and was selected as our consultant. The entire SIG team is truly expert at what they do and our project was able to earn LEED EB Gold, perform full Retro-Commissioning, increase our Energy Star score several points, and meet the Local Law 87 mandate!”
