MECHANICAL ENGINEERING

At PEI Engineering, our mechanical engineers design high-performance HVAC systems that ensure occupant comfort, energy efficiency, and long-term reliability. From concept through construction, we deliver solutions tailored to each building’s use, climate, and operational goals. Our designs integrate seamlessly with architectural and electrical systems while meeting all applicable building codes, energy standards, and sustainability objectives.

Heating, Ventilation, and Air Conditioning (HVAC) System Design
Comprehensive HVAC system design for commercial, institutional, and industrial buildings, including load calculations, equipment selection, and ductwork layouts.

Energy Analysis and Load Calculations
ASHRAE-based cooling and heating load analysis, system sizing, and energy modeling to optimize efficiency and performance.

Air Distribution and Ductwork Design
Design of supply, return, and exhaust air systems ensuring proper air balance, comfort, and noise control.

Hydronic Piping Systems
Design of chilled water, hot water, and condenser water piping systems with pump selection and pipe sizing.

VRF / VRV and Split System Design
Variable refrigerant flow system design for flexible zoning and high efficiency in offices, multifamily, and mixed-use buildings.

Packaged Rooftop and Air-Handling Unit Design
Selection and layout of packaged units, air handlers, and terminal boxes coordinated with architectural and structural requirements.

Ventilation and Indoor Air Quality
Design of mechanical and natural ventilation systems to meet ASHRAE 62.1 requirements and enhance occupant health.

Exhaust and Specialty Systems
Design of restroom exhaust, kitchen hoods, laboratory fume exhaust, and garage ventilation systems per code.

Building Automation and Control Systems
Specification and coordination of HVAC control systems and integration with building management systems (BMS).

Energy Code Compliance and Documentation
Preparation of energy compliance documentation per ASHRAE 90.1, IECC, and local code requirements.

Sustainability and Green Building Design
Integration of energy recovery, demand-control ventilation, and sustainable HVAC strategies for LEED and high-performance buildings.

Construction Administration and Field Support
Submittal review, RFI responses, field observation, and final system commissioning support to ensure performance and compliance.
