What We Do
Mechanical and energy engineering for complex buildings in the New York City metro area.
Pearson Rundell focuses on two disciplines: mechanical engineering and energy engineering. We work on complex building types — hospitals, universities, laboratories, government facilities, and large commercial properties — where the systems must perform reliably and the engineering demands real expertise.
Every engagement is led directly by a principal. Our clients get experienced engineers, not junior staff, from the first meeting through project delivery.
Discipline 01
We design, specify, and engineer mechanical systems for new construction and existing building upgrades. Our work spans the full range of HVAC and central plant systems across demanding NYC building types.
Mechanical design for new construction and renovation projects, from system selection and load analysis through construction documents and construction administration. We design systems that are reliable, maintainable, and appropriate for the building and its occupants.
Engineering design for chilled water plants, heating plants, and central thermal systems. This includes equipment selection, system configuration, hydronic design, and integration with existing infrastructure — with an emphasis on long-term reliability and operational clarity.
Evaluation and engineering of upgrades to existing HVAC and mechanical systems. We assess current system performance, identify improvement opportunities, and produce engineering packages suitable for procurement and construction.
Owner's-side commissioning support and design-phase commissioning coordination for mechanical systems. We help owners ensure that new and upgraded systems are installed, started up, and performing as designed before project closeout.
Discipline 02
New York City's energy code environment is among the most demanding in the country. We help building owners understand their exposure, meet their compliance obligations, and access utility incentives that improve project economics.
Systematic evaluation of building energy performance, including ASHRAE Level I and II energy audits, energy use intensity benchmarking, and identification of efficiency measures with meaningful payback potential. We produce clear, actionable findings, not just reports.
Engineering analysis and compliance planning for New York City's Local Law 97 carbon limits. We assess current and projected emissions, model compliance pathways, and help owners make capital decisions that are technically sound and financially rational.
Identification, scoping, and application support for utility incentive programs available to NYC building owners through Con Edison and NYSERDA. When energy improvements are properly engineered and quantified, utility incentives can materially reduce project cost.
Whole-building energy modeling in support of design optimization, code compliance, incentive applications, and LL97 analysis. We use energy models as engineering tools — not just compliance checkboxes — to inform system selection and capital planning.
Markets We Serve
Hospitals, ambulatory care facilities, and clinical environments where uptime and code compliance are non-negotiable.
Universities, research facilities, and institutional campuses with large, complex mechanical infrastructure.
Facilities with demanding HVAC and process requirements, including cleanrooms, laboratories, and regulated environments.
Large commercial office and mixed-use buildings in the NYC metro area navigating energy code and capital reinvestment decisions.
NYC agency and authority clients with public-sector procurement requirements and complex existing facilities.
Museums, performing arts facilities, and nonprofits in New York City managing aging building infrastructure with constrained budgets.
We're happy to have a preliminary conversation about your facility and what you're trying to accomplish before any formal engagement.
