MECHANICAL ENGINEERING
Practical Engineering
for Real-World Buildings.
FUNCTION provides mechanical engineering design services for commercial buildings, with particular expertise in renovations, equipment replacements, and phased system upgrades.
Our approach considers more than equipment selection and code compliance. We evaluate existing infrastructure, construction constraints, controls integration, and long-term operation to develop solutions that are practical to build and maintain.
WHAT WE DESIGN
Mechanical Engineering Services
Practical mechanical design solutions for existing commercial buildings, with an emphasis on integrating new equipment and systems into existing infrastructure.
HVAC Renovations & Retrofits
Modifications to existing HVAC systems that account for modern loads, operational needs, construction constraints, and available infrastructure.
Evaluate and design replacements and upgrades for hydronic, steam, and air systems, with an emphasis on reliability, performance, efficiency, and maintainability.
Equipment Replacement & Upgrades
DDC Controls and Integration
Clear, accurate sequences of operation aligned with ASHRAE Guideline 36 and applicable energy codes, accounting for equipment capabilities, required accessories, and integration with existing building automation systems.
Upgrade strategies that accommodate owner budgets, occupied buildings, operational continuity, and future system modernization.
Phased Construction & System Modernization
OUR APPROACH
Design Informed by Experience.

FUNCTION draws on firsthand experience in construction, building automation, commissioning, and troubleshooting to develop solutions that work beyond the design phase.
Good mechanical design requires more than selecting equipment and producing drawings.
We consider how systems will be installed, controlled, tested, maintained, and adapted over time—helping owners make informed decisions and avoid unnecessary complexity.
