Coronavirus Update/ Returning to the Office: AEI's is in the process of preparing our office for staff to return on a modified schedule, providing the City of Boston re-opening guidelines continue to move forward. During quarantine, AEI's staff have successfully worked remotely. Every staff member is equipped with the same equipment at home as they have in the office to ensure efficiency and seamless transitions between workstations. We will continue to work remotely and will provide a formal reopening date when it's available. At this time, only staff will be allowed in our space. Our contact information and policies on in person meetings and site visits remain the same as they have since early March. Please feel free to contact us if you have questions.

How we work

Our services are provided in the spirit of extraordinary teamwork and we engage stakeholders in all phases of a building project from feasibility study through construction. Careful attention to system selection, performance, cost, energy use, and opportunities for increased value to the owner is paid to each project without exception. We have a deep respect for the integration of mechanical and electrical system technology with the architecture of the building. And, our commitment to client service, collaboration, and technical mastery has led architects, owners and other engineering firms to entrust us with their important projects. We began priming work in 2002 and enjoy a nearly equal balance of prime and sub-consultant work.

With today’s complex project needs, we engage our clients throughout the design and construction administration process in a variety of ways:

  • Early in design, we educate stakeholders about the implications of design decisions, we engage town officials to ensure code compliance, and we explore utility rebate programs.
  • Using BIM and other modeling approaches such as clash detection, advanced lighting programs and laser scanning, we confirm performance and ensure building integration.
  • We collaborate continuously with our design team partners and involve industry experts, such as commissioning agents, acoustic consultants, cost estimators, surveyors, and medical designers among others, to ensure a full understanding of leading-edge technologies.
  • Working alongside contractors, we follow our designs through construction, and once the building is occupied, we seek valuable feedback to continuously improve our work.

AEI is a certified women-owned WBE/DBE engineering firm operating from Boston, Massachusetts. We also hold WBE status in Connecticut and Rhode Island.

Founded in 1985 by Robin Greenleaf, AEI provides innovative solutions to engineering problems in the building systems industry. We do so in in the spirit of extraordinary teamwork and partnership. Our project experience includes heating and air conditioning, plumbing, electrical lighting and power systems, instrumentation, and fire protection engineering. Because we have assembled all of these disciplines in one firm, we assure a well-coordinated design product. AEI provides professional support throughout the construction phase, which enables us to provide an immediate response to construction-related issues.

AEI has been certified by the state of Massachusetts as a women business enterprise (WBE) and disadvantaged business (DBE) since 1986.

The principals of AEI are registered professional engineers in all of the New England states and are licensed in mechanical, electrical, fire protection, and civil/ structural engineering. Our principals and project managers average more than 25 years’ experience, and all principals are LEED accredited professionals.

AEI fully embraces the principles of sustainable design and strives to incorporate environmental responsibility, resource efficiency, occupant comfort, and community sensitivity into our engineering solutions.

Our portfolio includes virtually every project type – laboratories, academic facilities, state office, public safety, municipal buildings, airport terminals, courthouses, transportation / infrastructure, commercial high-rise office buildings, corporate headquarters, tenant interiors, residential towers, libraries and museums. Our clients include federal and state agencies, municipalities and towns, and private corporations and owners.

We understand that each project requires a fresh perspective that requires active participation from all stake holders. We understand that collaboration requires an ability to listen, a willingness to pursue alternatives, and a knack for knowing what questions to ask at the appropriate time.

We have LEED accredited staff in every discipline and are committed to educating our clients about the latest relevant engineering solutions. We are active in many professional associations and serve in leadership roles of ACEC, ACEC/MA, IESNA and PWC Boston.

AEI began priming work in 2002 and often enjoy reciprocal relationships with many of our clients. Sitting on both sides of the table enables us to practice from a unique perspective. As a sub-consultant, we understand the challenges our prime clients face, and we work towards making our interactions easier. As a prime consultant, we recognize our sub-consultants focus and work to bring them into a more integrated project experience.
