Core Responsibilities

Primary Functions

Develop detailed HVAC system designs, including ductwork, piping, and equipment layouts, from conceptual sketches to final construction documents using Revit and AutoCAD.
Perform comprehensive heating and cooling load calculations using industry-standard software like Trane TRACE or Carrier HAP to accurately size equipment.
Select appropriate HVAC equipment, such as air handling units, chillers, boilers, and VAV boxes, based on project specifications, performance requirements, and energy efficiency goals.
Design and lay out ductwork and hydronic piping systems, ensuring proper sizing, routing, and coordination with other building systems like structural and electrical.
Create and manage detailed HVAC construction drawings, schedules, specifications, and other technical documentation required for permitting and construction.
Ensure all designs comply with relevant building codes, industry standards (e.g., ASHRAE 62.1, 90.1), and local jurisdictional requirements.
Collaborate closely with architects, structural engineers, electrical engineers, and plumbing designers to integrate the mechanical design and resolve spatial conflicts.
Participate in multi-disciplinary coordination meetings, utilizing Navisworks or other clash detection software to identify and resolve design interferences.
Prepare detailed control diagrams and sequences of operation to ensure the HVAC system functions as intended and meets the building's operational needs.
Review and respond to contractor submittals, shop drawings, and Requests for Information (RFIs) during the construction administration phase.
Conduct site visits and field surveys to verify existing conditions, monitor construction progress, and ensure installation aligns with design documents.
Assist in the preparation of technical reports, feasibility studies, and cost estimates for proposed HVAC systems and modifications.
Apply principles of sustainable design to develop energy-efficient systems that may contribute to green building certifications like LEED.
Size and select ancillary components including pumps, fans, air devices, and hydronic specialties to complete system designs.
Perform static pressure calculations for duct systems to ensure proper fan selection and airflow distribution throughout the building.
Develop detailed plans, sections, and schematics to clearly communicate design intent to all project stakeholders.
Revise and update existing drawings to reflect design changes, field conditions, and as-built information.
Assist project managers in defining project scope, developing design schedules, and managing the design budget.
Evaluate and recommend new HVAC technologies and materials to improve system performance, reduce costs, and enhance sustainability.
Prepare ventilation calculations to ensure compliance with indoor air quality (IAQ) standards as per ASHRAE 62.1.
Coordinate equipment locations and sizes with architectural and structural elements to ensure a fully integrated building design.
Participate in commissioning activities to verify that systems are installed correctly and perform according to the design specifications.

Secondary Functions

Mentor and provide technical guidance to junior designers and drafters on the team.
Assist in the development and continuous improvement of internal design standards, templates, and best practices.
Participate in business development efforts, including contributing to project proposals and attending client interviews.
Engage in continuous professional development to stay current with the latest HVAC technologies, design software, and code updates.
