About

Our Story,
Our Journey

Prasino Engineering, LLC is an independent professional design and building commissioning firm whose primary focus is sustainability, with LEED Gold and Silver project experience. The firm was created by college friends, with the original concept taking shape during a Power Systems class at the Milwaukee School of Engineering. Founded in February 2013, Prasino Engineering is owned and operated by licensed professional engineers with over 45 years of combined industry experience. We specialize in higher education, K 12, healthcare, mission critical, commercial, and transportation facilities

AREAS OF FOCUS

Our Focus

While our primary business line includes commissioning and retro commissioning services, we also provide Energy Analysis and Design, LEED services, MEP and Fire Protection Design, Facility Assessments, Code Compliance, lighting and control systems, Power System Reliability studies, Low Voltage Systems, Circuit Breaker Coordination Studies, Arc Flash Hazard Evaluations, and Thermal Imaging.

We understand the importance of project success and deliver an integrated, owner focused approach. Our team works closely with Owners and project stakeholders to provide cohesive, technically sound solutions to complex problems. We have a proven track record of going beyond baseline expectations to verify Owner requirements are met. Prasino Engineering, LLC supports facilities across new construction, renovations, infrastructure capacity evaluations, and regulatory compliance.

key differentiators

direct leadership access

You work directly with the firm’s leadership from start to finish. No handoffs, no substitutes, just the people whose names are on your proposal, ensuring accountability, clarity, and consistency throughout the project.

Licensed Expertise

Every engineer on your project is a licensed Professional Engineer. Our team brings deep technical proficiency, ensuring decisions are informed, accurate, and aligned with industry standards at every stage.

Independent Commissioning

Commissioning isn’t a secondary service, it’s our core business. As a true third-party commissioning firm, we provide unbiased, owner-focused verification without design conflicts or divided priorities.

Advanced Tools & Technology

We bring our own calibrated diagnostic equipment to every project, eliminating reliance on contractors. From thermal imaging to airflow measurement and building pressure diagnostics, our tools produce precise, defensible results. Our proprietary Cx software and AI-powered site analysis enhance accuracy, documentation, and field reporting.

Integrated Project Approach

Our commissioning process is aligned with construction sequencing to minimize disruption and identify issues early. We collaborate closely with owners, architects, contractors, and inspectors to keep projects coordinated and moving forward.

Commitment Through Completion

Our involvement doesn’t end at turnover. We remain engaged through the warranty period, conducting post-occupancy check-ins to confirm that every issue is resolved and systems perform as intended long after opening day.
