Altieri provides comprehensive MEPF engineering design services – including master planning, existing conditions assessments, and investigative work – to architects and building owners. We are driven by a systematic and iterative approach valuing early engagement and a highly collaborative process throughout the project. The core of our design philosophy is to prioritize and meet design challenges presented by the client’s vision, ensuring that the MEPF system balances aesthetic, budgetary, sustainability, maintainability, and other program criteria while contributing to the overall quality of the architecture. Each project is overseen by a Project Manager, our main point of client contact and coordination with the design team. Our engineers develop designs targeted to optimize energy efficiency, create expansive abilities for redundancy, and simplify the organization of systems to minimize maintenance and operation costs, and maximize reliability. Our Principals provide overall guidance, ensuring that the systems we design prioritize the quality, character, and integrity of the architecture and maintain the architect’s vision as our paramount intention. Our decades-long experience successfully meeting high profile design challenges continues to set the pace for the industry.


We design the best solutions for each project, ensuring that systems support program requirements, are as minimally intrusive as possible, and enhance the user experience. We have expertise in all aspects of mechanical design including:

• Building Automation and Energy Management Systems
• Standards for Indoor Environmental Conditions
• Central Heating and Cooling Plant Infrastructure
• Campus Energy Distribution
• Central Air Handling and Ductwork Distribution

Our work product is produced using the latest version of Autodesk Revit.


We design systems with expansive abilities for redundancy, keeping buildings operable and mitigating risk in the event of system interruption or failure. Our designs utilize an array of components – emergency power and standby power generation plants, multi-fuel systems of generators, uninterruptible power supply systems, multiple power supplies – determined by the needs of specific programs that range from preserving museum collections to protecting aquarium ecosystems. We have considerable experience designing systems that comply with FEMA floodproofing requirements including projects at Brooklyn Bridge Park, Domino Park, Gansevoort Peninsula at Hudson River Park, and South Street Seaport.
