Thoughtful Design for Buildings That Must Perform—Today and for Decades to Come

360 Engineering provides full-service mechanical and plumbing engineering for new construction, renovations, retrofits, and complex existing or historic buildings. Our work spans education, government, recreation, science and technology, and commercial facilities—each with unique constraints, users, and long-term operational needs.

We believe great engineering starts with listening. By partnering closely with owners, architects, contractors, and engineering team members, we take time to get on the same page right away, understanding the big picture, project goals, and overall needs of the client. We design HVAC and plumbing systems that balance budget, efficiency, comfort, safety, and sustainability—while remaining practical to operate and maintain. From early system assessments through construction support and commissioning, we help clients make informed decisions that reduce risk and deliver long-term value.

Where We Work:

Sustainable, High-Performance HVAC & Plumbing Design

High-performance design is not one-size-fits-all—it’s about finding the right solutions for each project. Our engineers integrate energy efficiency and sustainability into every project by evaluating systems holistically rather than in isolation. We help clients navigate evolving technologies, energy codes, and performance goals with clear, data-driven guidance. 

Our designs focus on reducing energy and water use, improving occupant comfort and indoor air quality, supporting electrification and decarbonization goals, and delivering dependable, maintainable performance over time.

Expertise in Existing, Historic, & Complex Buildings

Some of our most impactful work happens inside buildings that are already standing—and often still operating. We specialize in assessing, modernizing, and upgrading aging HVAC and plumbing systems where space is limited, documentation is incomplete, or historic preservation is critical.

Our process begins with understanding how systems have performed over time. We then present clearly defined options that balance first cost, lifecycle performance, operational reliability, and future flexibility—resulting in solutions that respect the past while preparing buildings for the future.

Prime Engineering Consulting Services

Leadership, Coordination, and Confidence—From Concept Through Construction 

360 Engineering provides prime engineering consulting services for facility upgrades, equipment replacements, and complex design projects. Acting as the lead consultant and project manager, we guide and coordinate multidisciplinary teams from early goal setting through construction and closeout—keeping projects focused, aligned, and moving forward.

Our approach is rooted in clear planning, strong communication, and accountability. We assemble the right partners, establish expectations early, and proactively manage schedule, budget, and risk—helping clients navigate regulatory requirements, market conditions, and evolving project needs with confidence. 

Integrated Project Leadership & Team Coordination 

Successful projects depend on early alignment and consistent leadership. As prime consultant, we guide architects and engineering teams through every phase—ensuring collaboration, transparency, and shared accountability. 

Through structured communication, regular coordination meetings, and proactive issue resolution, we help complex ideas become buildable solutions while keeping client priorities at the center of every decision. 

Schedule, Budget, & Construction Management 

Maintaining control of schedules and budgets is fundamental to our consulting approach. We identify risks, long-lead items, and cost drivers early, allowing informed decisions before issues escalate. 

Through realistic scheduling, value-driven documentation, and close coordination with contractors and cost professionals, we help clients achieve best-value outcomes while accommodating operational needs and market realities. 

Risk Mitigation & Client-Focused Solutions 

Every project encounters challenges. Our role is to anticipate them, communicate clearly, and guide teams toward practical resolutions. When issues arise, we facilitate structured discussions that align stakeholders and keep projects moving forward.

As a prime engineering consultant, our success is measured by client confidence, project clarity, and long-term facility performance.

Energy & Commissioning Services

Smarter Energy Decisions That Deliver Long-Term Performance 

360 Engineering provides comprehensive energy and commissioning services for new and existing facilities—helping owners reduce energy use, improve system performance, and meet increasingly rigorous energy and sustainability requirements. 

By aligning energy goals early, we deliver a holistic, integrated approach that combines energy modeling, responsible system design, commissioning, and optimization. Our team collaborates closely with owners, architects, and contractors to ensure buildings operate as intended—not just at turnover, but throughout their lifecycle. 

Strategic Energy-Efficient Building Design

Every project begins with understanding what matters most to the owner—whether reducing operating costs, supporting electrification, achieving net-zero goals, or balancing performance within tight budgets. 

Rather than focusing on equipment alone, we evaluate whole-building performance, considering envelope, systems, controls, and operational realities. Drawing on experience across building types and climates, we clearly outline cost, performance, comfort, and maintenance tradeoffs to support confident decision-making. 

Certifications, Compliance, & Sustainable Practices

As energy codes and performance standards continue to evolve, we help clients stay ahead with responsible, code-compliant, and future-ready solutions. Our services include energy audits, energy modeling, commissioning and retro-commissioning, and performance verification. These services are supported by our Professional Engineers, ASHRAE High-Performance Building Design Professionals, ASHRAE Building Energy Modeling Professionals, USGBC LEED Certified, and ACG Accredited Commissioning Agents.

These efforts support not only compliance, but healthier buildings, improved occupant experience, and long-term operational confidence.
