Building Systems Engineering information

What is building systems engineering?

Building Systems Engineering is a multidisciplinary field focused on the design, integration, operation, and maintenance of a building’s essential systems, such as HVAC (heating, ventilation, and air conditioning), electrical, plumbing, and fire protection. Engineers in this field ensure that these systems work together efficiently to provide comfort, safety, sustainability, and functionality within buildings. They collaborate closely with architects and construction professionals to meet regulatory standards and optimize building performance. Building Systems Engineers play a key role in improving energy efficiency and supporting green building initiatives.

What are the key skills and qualifications needed to thrive as a building systems engineer?

To thrive as a Building Systems Engineer, you need a solid background in mechanical, electrical, or civil engineering, often supported by a relevant engineering degree and professional certification (such as PE or EIT). Familiarity with building automation systems, HVAC, AutoCAD, and energy management software is typically required. Strong problem-solving abilities, attention to detail, and effective communication skills enable you to collaborate with diverse stakeholders and ensure system reliability. These competencies are crucial for designing, maintaining, and optimizing safe, efficient building environments.

What are some common challenges faced by building systems engineers when working on retrofit projects in existing structures?

Building Systems Engineers often encounter unique challenges during retrofit projects, such as integrating modern systems with outdated infrastructure and ensuring compliance with current codes. Limited access to existing mechanical, electrical, or plumbing systems can complicate upgrades, requiring creative problem-solving and collaboration with architects and contractors. Additionally, balancing energy efficiency improvements with budget constraints and minimizing disruptions to occupants are key considerations that demand both technical expertise and strong communication skills.

What is the difference between Building Systems Engineering vs Mechanical Engineering?

AspectBuilding Systems EngineeringMechanical Engineering
CredentialsBachelor's in Engineering, PE license often preferredBachelor's in Mechanical Engineering, PE license common
Work EnvironmentDesigning and managing building systems like HVAC, plumbing, electricalDesigning mechanical devices, engines, manufacturing systems
Industry UsageConstruction, building design, facilities managementManufacturing, automotive, aerospace, energy

Building Systems Engineering focuses on designing and maintaining building infrastructure systems, while Mechanical Engineering covers a broader range of mechanical devices and systems across various industries. Both roles require similar credentials and often work within the construction and manufacturing sectors, but their specific applications differ significantly.

Are building systems engineers in high demand?

Building systems engineers are in high demand due to the need for efficient design, installation, and maintenance of building automation, HVAC, and electrical systems. The role requires technical skills, knowledge of industry standards, and often certifications, with employment opportunities growing as building complexity and sustainability efforts increase.

What does a building systems engineer do?

A building systems engineer designs, analyzes, and maintains the mechanical, electrical, plumbing, and control systems that ensure a building's safe, efficient, and reliable operation. They often use tools like CAD software and may hold certifications such as LEED or PE. Their work involves coordinating with architects and contractors throughout construction and maintenance phases.

Position Overview:
New Ecology, Inc. is seeking an engineering candidate with 3-5 years of experience for the position of Energy Engineer 2. The successful candidate will primarily work out of NEI's Wilmington, DE office. This position is part of our growing Decarbonization Division. The Decarbonization Engineering team works with building owners and developers to provide services that reduce carbon emissions and improve building performance, operation, resiliency, and resident health and comfort. Services include benchmarking building energy performance, assessing existing conditions and developing scopes of work for improvement, estimating savings and cost, predicting compliance with regulations, assisting with implementation tasks and more.


The Energy Engineer 2 will provide technical and construction management support to decarbonization projects in the Mid-Atlantic region. Work will require travel to client sites primarily in Delaware, and skills such as written and oral communications, comprehension of utility data and use thereof, building systems and energy auditing processes. This person will work with the team on program planning and ensuring services and results are delivered in compliance with utility[JI1] Β programs and client expectations. A typical workday may include: meet and interact with facilities managers and contractors on site to conduct energy audits, explore opportunities for upgrades of existing mechanical systems, prepare scopes of work for installation of efficiency upgrades, seek and evaluate competitive bids, conduct post-installation site inspections and verify work is done to specifications. New Ecology is developing an emerging service to help owners plan for decarbonization over time, and this person will assist in that effort. We are seeking a candidate with a mechanical engineering or related degree and experience with HVAC systems.


Duties and Responsibilities:
