• Why Commission?
• Developing NYP’s Commissioning Program
• NYP Commissioning Process
• Roles & Responsibilities
3 The Commissioning Process….
“A quality focused process for enhancing the
delivery of a project. The process focuses upon
verifying and documenting that the facility and all
of its systems and assemblies are planned,
designed, installed, tested, operated and
maintained to meet the Owner’s Project
Requirements (OPR).
-ASHRAE Guideline 0-2005-
Definitions
4 ASHRAE Guideline 0-2005: The Commissioning Process
(To be used as the foundation of ASHRAE Guideline 1 and the NIBS Total Building Commissioning
Process technical guidelines)
ASHRAE Guideline 1-200X HVAC&R Technical Requirements
for The Commissioning Process
NIBS Guidelines 2-200X through 14-200X Technical commissioning guidelines dealing with
lighting, fire, interiors, envelopes, plumbing, etc.
Guideline 1 – ASHRAE, HVAC&R System
Guideline 2 – ASCE, Structural Systems
Guideline 3 – BETEC, Exterior Envelope Systems
Guideline 4 – NRCA, Roofing Systems
Guideline 5 – AWCI, Interior Systems
Guideline 6 – NEII, Elevator Systems
Guideline 7 – ASPE, Plumbing Systems
Guideline 8 – IES, Lighting Systems
Guideline 9 – IEEE, Electrical Systems
Guideline 10 – NFPA, Fire Protection Systems
Guideline 11 – TIA, Telecommunications Systems
The Commissioning Process
5 • Evolving complexity of building control systems
• Modern ventilation, lighting and comfort systems are energy intensive
• Construction deficiencies at outset in most buildings
• Need for independent & objective peer review
• Operations & Maintenance (O&M) staff unprepared to operate complicated buildings efficiently
• Frequent user complaints
• Long term operating costs – utility costs & maintenance higher than expected
Why Commission?
6
Benefits of Commissioning
• Improved system & equipment function
• Increased occupant & owner satisfaction
• Lower utility bills through energy savings
• Significant extension of equipment/systems life-cycle
• Improved building occupant productivity
Benefits 2000 NYSERDA & 2001 PECI Surveys:
70% fewer post acceptance deficiencies
65% fewer occupancy complaints
50% decrease of litigation
65% improvement of comfort control
60% owners get what they paid for

Cx Agent – Roles & Responsibilities
• Enlisted in the project at earliest possible stage, Feasibility or Schematic Design
• Establish the Owners Project Requirements (OPR)
• Apply Best Practice standards during design review process
• Ensure the MEP installation and operation complies with the design intent and manufacturer’s specifications
• Ensure that the MEP installation will be maintainable by Facilities Operations
• Ensure O&M Materials and Warranty are available, scanned, indexed and appropriate for the installation
• Coordinate in Facilities Operations Staff Training
• Coordinate work with the Campus Engineer and Facilities Operations
• Develop Preventive Maintenance Program for installed equipment, in TMS format
19
Feasibility Phase
•Develop Owner’s Project Requirements (OPR) • Project Overview
• Functional Uses
• Occupant Requirements
• Performance Criteria
• Integrate stakeholders in this phase (clinical staff, O&M staff)
• Identify scope for Cx process
•Develop draft Cx Plan
The Basis of Design is the Design Team’s technical interpretation of the OPR
20
Design Phase

28
2013 Results • Over 100 projects successfully commissioned…
• Steam traps and condensate piping improperly installed.
– Heating coils could freeze and burst, resulting in AHU partial or
total shutdown
• Return fans trip on overcurrent during partial restart.
– The AHU unnecessarily shuts off, resulting in loss of space
pressurization and compromising patient safety.
• Thermostats wired/mapped to the wrong rooms.
– Patients would not be able to control the temperature in their
rooms compromising patient comfort.
• Fire-smoke dampers not wired to the building automation system.
– Remote status of dampers in ceilings above patient rooms would
not be available requiring manual inspection and temporary
shutdown of patient rooms.
29
2013 Results • Isolation Room was found to have insufficient pressurization
– Installation of door sweep improved pressurization of the Isolation Room;
pressurization improved from -0.003 in w.c. to -0.007 in w.c.
• Review of the HVAC Balancing Report – key for DOH inspection –
identified multiple errors.
– Unbalanced VAV boxes cannot maintain room temperature setpoints and lead
to patient discomfort.
• Selected Balancing Contractor was found to be uncertified for
Testing and Balancing (TAB) per NYPH Engineering Standards.
• Thermostat for a VAV serving Patient Rooms was found to be
incorrectly installed in the Suite corridor
– Relocation of the patient room VAV’s thermostat now accurately reflects zone
conditions and improves patient comfort, as well as Facilities Operations’
troubleshooting capabilities.
30
2013 Results • Cooling condensate coils were not piped.
– Water would drain onto the original roof in the interstitial space under the new
MER.
• The original design proposed a single-fan air handling unit.
– The system would have to be shut down entirely to change the main filters,
resulting in significant ILSMs for planned maintenance.
• Sections of ductwork repeatedly failed pressure tests.
– There would have been significant duct leakage resulting in energy losses.
• Systems reported as complete were not fully operational.
– Spaces would have to be taken off-line after patient occupancy for repairs.
• VAV box control points on the Siemens BMS identified incorrectly
tagged/addressed VAV boxes.
– Improperly addressed boxes diminish Facility Operation’s ability to respond to
patient and staff temperature requirements, and maintain incorrect space
temperature setpoints for patient rooms.
