Core Responsibilities

Primary Functions

Develop comprehensive HVAC system designs, including conceptual and detailed plans for new construction and renovation projects, ensuring alignment with client objectives and architectural vision.
Perform detailed heating and cooling load calculations (e.g., using block loads, peak loads, and room-by-room analysis) to accurately size and specify system components.
Design and layout ductwork and piping systems, including sizing, routing, and detailing for optimal airflow and hydraulic performance while coordinating with other building disciplines.
Select and specify major HVAC equipment, such as chillers, boilers, air handling units (AHUs), rooftop units (RTUs), and VRF systems, based on performance requirements, energy efficiency, and life cycle cost analysis.
Create and interpret psychrometric charts to analyze air-conditioning processes and ensure system designs will achieve desired indoor environmental conditions for comfort and process control.
Prepare detailed construction documents, including mechanical drawings, schematics, equipment schedules, and technical specifications for bidding and construction purposes.
Conduct thorough reviews of local, state, and national building codes and standards (e.g., ASHRAE, SMACNA, IMC) to ensure all designs are fully compliant.
Perform energy modeling and analysis using software like Trane TRACE 3D Plus or Carrier HAP to evaluate system options, predict energy consumption, and support sustainable design goals like LEED certification.
Prepare technical reports, feasibility studies, and basis of design documents to communicate design intent, system alternatives, and engineering recommendations to stakeholders.
Review and respond to contractor submittals, shop drawings, and Requests for Information (RFIs) during the construction phase to ensure adherence to design specifications.
Conduct site visits and field inspections to monitor construction progress, resolve field-related issues, and verify that installation conforms to contract documents.
Collaborate with controls engineers to develop and refine building automation system (BAS) sequences of operation for optimal system performance and energy management.
Provide engineering support during the system startup and commissioning process, assisting with functional performance testing and troubleshooting to ensure systems operate as designed.
Interface directly with clients, architects, and other engineering disciplines (structural, electrical, plumbing) to ensure a coordinated and integrated project design.
Utilize Building Information Modeling (BIM) software, primarily Revit MEP, for 3D modeling, clash detection, and coordination of HVAC systems with other building elements.
Analyze and troubleshoot performance issues in existing HVAC systems, recommending and designing cost-effective retrofits or upgrades to improve efficiency and reliability.
Manage multiple projects concurrently, effectively prioritizing tasks to meet deadlines and budget constraints without compromising quality.
Mentor junior engineers and designers, providing technical guidance, reviewing their work, and fostering their professional development within the team.
Stay current with the latest HVAC technologies, industry trends, and sustainable design practices to continuously enhance the firm's engineering capabilities.
Participate in pre-bid meetings and assist in the preparation of engineering service proposals, including scope definition and fee estimation.

Secondary Functions

Support the business development and sales teams by providing technical expertise and participating in client presentations.
Contribute to the development and maintenance of internal engineering standards, design tools, and calculation templates.
Engage with professional organizations like ASHRAE to represent the firm and stay at the forefront of the industry.
Assist project managers with budgeting, scheduling, and resource allocation for the mechanical scope of work.
