02 — THE ENGINEER
I DESIGN THE
SYSTEMS MANHATTAN
RUNS ON.
I'm Alex Moreno, a licensed Professional Engineer specialising in HVAC systems for New York City's most complex built environments. I've spent 18 years working at the intersection of mechanical engineering, building performance, and the unique constraints of urban construction.
Manhattan buildings don't forgive poor engineering. Tight mechanical rooms, landmark preservation rules, noise ordinances, Con Edison interconnects — I design systems that work within the actual conditions of New York real estate.
Every system I design should be invisible when it's working and understandable when it isn't. I write specifications contractors can build from, produce drawings that withstand DOB review, and stay on projects through commissioning.

03 — SCOPE OF PRACTICE
EVERY SYSTEM,
FROM SCHEMATIC
TO SIGN-OFF.
Six coordinated practice areas presented as a clear service matrix.
02
Load Calculations & Energy Modeling
ASHRAE-compliant heating and cooling load analysis with energy modeling to optimize system selection and meet Local Law 97 benchmarks.
03
System Commissioning
Functional performance testing and verification for new and existing HVAC systems — ensuring your equipment operates as designed before occupancy.
04
Retrocommissioning & Retrofits
Diagnostic assessment and re-engineering of underperforming systems in existing buildings. Finding the gap between what your system is doing and what it should be doing.
05
Air & Water Balancing
Testing, adjusting, and balancing of air distribution and hydronic systems to verify design flow rates and eliminate comfort complaints across all zones.
06
Controls & BAS Integration
Specification and coordination of building automation systems, DDC controls, and smart building integrations — designed for operator usability, not just code compliance.

Hudson Yards Mixed-Use Tower
Hudson Yards, Manhattan · 2022
CHALLENGE ——
Base building mechanical design inherited mid-project. Duct layouts conflicted with structural beams; equipment undersized for revised tenant program.
SOLUTION ——
Full mechanical system review and reissued construction documents within eight weeks. Redesigned kitchen exhaust routing and upsized chilled water piping.

Park Avenue Residential Tower
Midtown East, Manhattan · 2021
CHALLENGE ——
A 42-story 1960s tower with original two-pipe steam heating — chronic overheating complaints and escalating fuel costs. Phased retrofit required with no full-building shutdowns.
SOLUTION ——
High-efficiency two-pipe hydronic system replacing steam throughout, phased over four construction seasons. Preserved existing riser shafts.

SoHo Landmark Conversion
SoHo, Manhattan · 2023
CHALLENGE ——
Cast-iron landmark conversion. LPC restrictions prohibited rooftop equipment visible from the street; no facade penetrations permitted. Building had no existing mechanical infrastructure.
SOLUTION ——
Fully concealed VRF system with condensing units in a rear mechanical penthouse screened below the cornice line. Air distribution routed through the existing tin ceiling cavity.

05 — HOW I WORK
A METHODOLOGY AS
STRUCTURED AS THE
SYSTEMS I DESIGN.
Six clear project phases, presented as a readable workflow instead of a pinned transition sequence.
01
DISCOVERY & SITE SURVEY
Before any calculation, I visit the site. I document existing conditions, photograph mechanical spaces, and map constraints that won't appear on any drawing set.
02
LOAD ANALYSIS & SYSTEM SIZING
ASHRAE-compliant heating and cooling load calculations, performed in-house. Equipment is sized to the actual load — not the nearest catalog selection.
03
SCHEMATIC DESIGN
System concept presented in plain language and schematic drawings. Equipment type, distribution strategy, and spatial impact — reviewed and approved before advancing.
04
CONSTRUCTION DOCUMENTS
Full mechanical drawing set and specifications produced to DOB filing standards. Coordinated with architectural and structural drawings. Ready for contractor bidding.
05
CONSTRUCTION ADMINISTRATION
Shop drawing review, RFI responses, and site observation during installation. Verifying that what gets built matches what was designed — and flagging deviations before they're buried in the wall.
06
COMMISSIONING & HANDOFF
Functional performance testing of all systems. Final TAB report review. Owner training on system operation. Written record of as-designed vs. as-built performance.
