Steve personally oversees the development of individual projects and oversees respective project teams in the execution of activities for the owner. From the world of design his interests evolved into project management. After his service as a US Navy pilot, he joined Bechtel in San Francisco. His work included nuclear and fossil power plants and the creation of a new city in Borneo as Senior Project Planner. Subsequently for a consulting firm, he successfully executed the work out of a contractor default on 22 projects of $500M (1981) in bonded value across the US for Travelers.

Many years of experience in project management of both design development and construction of numerous projects across the United States and in several countries overseas informs his work. Steve has a unique background in a diversity of projects that range from heavy industrial to high-value commercial and residential. In addition to building design and construction, Steve has extensive experience in pre-construction planning, land development and infrastructure related to site work development.

As a result of his official role in the 1996 UN Habitat II Conference in Istanbul, Turkey; Steve has been exploring and implementing options of bringing sustainable development practices into his work and into the mainstream of design and construction. Based on the recent Chandler project of an energy retrofit of the Princeton Club of NY, he published a white paper with Environmental Design+Construction promoting a national retrofit program that evolved into the Connecticut C-PACE Program. Steve is a guest lecturer on the subject at the New York University Shack Institute of Real Estate Center for the Sustainable Built Environment (SBE).

Steve has immersed himself in energy efficiency technology exploring all aspects with strategic partners evaluating a number of projects some small, others quite large. He is a trusted advisor for project development to Aether LLC, on an innovative funding model for very large projects. He has been accredited by the Investor Confidence Project as well as by the Connecticut Green Bank as a C-Pace Contractor.

Donald Proto
Project Development Associate

Education:  BA Architecture, Pratt Institute.


Don Proto has an extensive hands-on history in project development from design through construction to commissioning with significant experience in the public sector. He holds a BA in Architecture from Pratt Institute. That education was the foundation for a successful career in project development and management with a focus on energy efficiency projects.

Early in his career he held the position of Director of Construction Management & Capital Improvements for a town in Connecticut responsible for creating viable operating budgets and cost accounting functions for over $100M in capital projects. Moving to a role as a consultant, Don conducted analyses for the creation of program solutions presented to public housing authorities,
municipalities, utility companies, and non-profit organizations. He acquired specialty expertise to analyze client requirements, conduct in-depth energy audits as well as HUD Uniform Physical Condition Standards (UPCS) inspections and insurance loss control reports.

In recent years his work for design-build contractors for energy efficiency projects nationally and in the Northeast included NORESCO and PPL SavageAlert, a subsidiary of Pittsburgh Power and Light. Both firms were well established national and regional energy performance contractors. At each firm he worked closely with engineering to develop viable energy projects with a variety of energy efficiency measures that usually included tri or cogeneration and at times hybrid solutions with solar.
At NORESCO Don was tasked as Senior Program Manager to leverage capital expenditures with energy financed loans to realize financial viability for clients and their asset management needs. The basis for this work was preparation of physical needs assessments and facility operating budgets for clients with multi-site building portfolios. He collaborated with public housing authorities as liaison with HUD. He established energy conservation metrics with financial solutions for operating and
utility cost reductions. He concluded negotiations with the Boston Housing Authority for the extension of an existing energy performance contract valued at $18 million. 

At both firms the scope of work included a variety of public buildings and schools.
