Technical Excellence in Sustainable Mechanical Design

Integrated MEP’s mechanical engineering team brings proven expertise in delivering high-performance, energy-efficient building systems. Our portfolio includes projects achieving LEED (Leadership in Energy and Environmental Design) certification, where sustainability objectives are met through rigorous adherence to performance standards. Select LEED criteria are systematically integrated into our internal design protocols, ensuring consistent delivery of sustainable outcomes across all projects to enhance efficiency, reduce environmental impact, and improve occupant well-being.

Our plumbing designs standardize the specification of EPA WaterSense-labeled and LEED-compliant low-flow fixtures, including lavatory faucets, sink faucets, high-efficiency water closets, and high-efficiency urinals. Standard systems are designed to achieve a minimum of 20% water use reduction compared to the LEED baseline, as defined by the Energy Policy Act of 1992 and subsequent updates. For projects prioritizing water efficiency, we incorporate plumbing fixtures capable of achieving up to 60% aggregate potable water reduction, supported by calculations in accordance with LEED v4/v4.1 WE Credit requirements.

Integrated MEP strictly adheres to ASHRAE Standard 90.1—“Energy Standard for Buildings Except Low-Rise Residential Buildings”—across all mechanical and plumbing system designs. Our design and equipment selection ensure compliance with all applicable minimum performance levels, including:

• HVAC system efficiency thresholds,
• Economizer integration,
• Pipe and duct insulation,
• Building-level HVAC control strategies,

We routinely implement strategies where project goals support enhanced energy performance; every system is tailored to meet the project’s specific needs.

All receptacles installed in enclosed office spaces, conference rooms, breakrooms, classrooms, and individual workstations (including those with modular partitions) shall be split controlled with the exceptions of spaces in accordance with section C405.11.1 of the IECC.

These controls shall follow one of the following methods: time-of-day controlled, occupancy sensor controlled, or an automated signal from another control or alarm system that shall turn off receptacles within 20 minutes after determining the area is unoccupied.

We prioritize occupant health and comfort through well-ventilated, intelligently controlled HVAC designs. Our engineers calculate precise ventilation requirements for each space, and integrate strategies like demand-controlled ventilation and CO₂ monitoring to optimize air quality while minimizing energy use.

Integrated MEP is a technical leader in the design of all-electric mechanical and plumbing systems, supporting compliance with stringent jurisdictional electrification mandates. We provide fully electric HVAC systems including air-source heat pumps, variable refrigerant flow (VRF) systems, and electric resistance backup as required. For fully electric domestic hot water systems we engineer heat pump water heaters with appropriate storage strategies to meet peak load profiles.

For projects where fossil fuels remain viable, we specify high-efficiency condensing equipment (up to 96% thermal efficiency), ensuring compatibility with ASHRAE 90.1 and local energy code requirements.
