Introduction

The commissioning plan is the reference document that identifies the strategies, aspects and

responsibilities within the commissioning process for each phase of the project for all project team members.

This document outlines the overall process, schedule, organization, responsibilities and documentation

requirements of the commissioning process for all commissioning team members.

The commissioning plan is developed at the start of the commissioning process, and is updated during

the course of the project to reflect any changes in planning, schedule or other aspect.

The required commissioning plan components as per LEED reference guide for green building design and

construction are as follows:

I‐ Overview of the commissioning process

Commissioning intent is to verify that the project’s energy related systems are installed, calibrated and

perform according to the owner’s project requirements, basis of design and construction documents and to

provide the owner with a high level of assurance that the mechanical and electrical systems have been

installed in the prescribed manner, and operate within the capabilities of the documented design and specified

equipment capacities.

In order to comply with the LEED requirements, the commissioning plan will be divided into two levels called

“Fundamental Commissioning” of building energy systems which is prerequisite for the system and

“Enhanced Commissioning” with its optional credits.

The prerequisite intent is to verify that the project’s energy related systems are installed, calibrated and

perform according to the owner’s project requirements, basis of design and construction documents.

The Commissioning authority will verify the installation and performance of the systems to be commissioned,

and will complete a summary commissioning report as part of the Fundamental commissioning process.

The commissioning authority will document all commissioning review process, submittals, system manual,

verify O&M training and review building operation after 10 month of final acceptance.

II‐ Systems and assemblies included in commissioning authority’s scope of work

The scope of services for the commissioning authority is based on the owner’s project requirements.

Thus, as requested by the owner, the mission will cover the following base building systems:

Ventilation systems(Supply air, Return air, Exhaust air)

HVAC and associated control systems

Chilled water

VRV system

Domestic water heating

Water distribution systems

Domestic water treatment

Electrical power generation and distribution systems

Building Management System

Sub‐meters and central electronic monitoring system

Lighting and lighting controls

Renewable energy systems

III‐ Commissioning team and its responsibilities

“Commissioning team” as defined in ASHRAE’s commissioning guide; it’s “Those people responsible for

working together in carrying out the commissioning process”.



Commissioning, at every stage of a project, is a collaborative effort between all parties to the construction

project; it’s a team effort and requires communication, coordination and cooperation among all parties

involved with the project. The commissioning authority is the leader of the team.

By clearly establishing the Commissioning Team and individual responsibilities, the process execution

becomes easier, more effective and more accountable.

Below are the commissioning team members, along with their individual responsibilities in the commissioning

process during project phases.

A. Owner (The African development Bank)

requested.

23‐ Repeat all required testing and verification procedures after 10 months of client’s

occupancy.

IV‐ Description of management, communication and reporting of commissioning process

Whole Building Commissioning is a process that relies upon high levels of communications and collaboration

between all parties to the construction process. By its nature, the levels of communication and cooperation

between the Commissioning Authority and all other parties to the construction process (Design team,

Engineers, Subcontractors, Vendors, third party testing agencies, etc.) is essential to the success of the

Commissioning effort. In the absence of these relationships, cooperation and support created by this

communication, the Commissioning Process will likely fail to achieve its ends.

With this fundamental conflict in mind, this section has been developed to recognize that, in the execution of

the Commissioning Process, the Commissioning Authority must develop effective methods to communicate

with every member of the construction team involved in delivering commissioned systems while

simultaneously respecting the exclusive contract authority of the Contracting Officer and his/her Designated

Representative.

The organizational process chart below shows lines of contractual authority in this project, yet

communications are encouraged between all commissioning team members, within the limit of their contracts.



V‐ Commissioning Plan

The commissioning plan is implemented during the construction phase. Direct interaction between the

construction team and the commissioning authority and communication with the design team represents the

cornerstone of successful commissioning.

The commissioning authority provides leadership by communicating goals for the commissioning process,

including identification of roles and responsibilities of team members, and clearly defining and documenting

pass/fail criteria. Each commissioning team member shares a responsibility to support the commissioning

process and achieve a quality installation.

The sequence and timing of commissioning activities must be incorporated into the overall project schedule.

The commissioning authority identifies the required commissioning activities. Coordination requires input

from the owner, designer, and contractors. Cooperation among the parties facilitates integration of

commissioning into the total construction program.

At this stage, the commissioning authority obtains and reviews submittal data, and consults with the

designers and contractors regarding conformance with the design intent. The designer provides final approval

of all submittals.

The commissioning authority should work with the general contractor to schedule commissioning meetings in

conjunction with regular progress meetings, because many participants will attend both. The commissioning

authority keeps meeting minutes.

All commissioning team members are responsible for attending commissioning meetings and for completing

assigned action items by the agreed dates. Cooperation by all parties contributes to successful commissioning.

The contractor is responsible for preparing the O&M documentation and training program in accordance with

specification requirements.

The O&M training program should include:

Design intent.

System limitations.

Start‐up and shut‐down procedures.

Modes of control and operation sequences.

Detailed review of the information and organization of the O&M manual.

Complete listing of contractors and manufacturer contact information.

Complete listing of spare parts.

Detailed instructions on the control system.

Routine preventative maintenance procedures as specified by the designer or recommended by the

manufacturer.

Provisions for safety shutdowns, emergency conditions, and interfaces with building management

systems (BMS) and life‐safety systems (such as fire protection).

Video tapes of the training sessions to allow future use.

At the last phase of this stage, the commissioning authority will be responsible of preparing a summary

commissioning report.

This report uses the final commissioning plan as its template. The report includes all system verification and

start‐up checklists, and all functional performance test checklists, completed with all test observations,

problems encountered, corrective actions taken, and re‐test results dated and signed by those carrying out and

witnessing the tests.

Where the checklists make reference to other test reports, copies of those reports must be appended. The final

commissioning report should contain an executive summary addressing design intent conformance for all

commissioned equipment and systems. The report should include references to all relevant commissioned

system documentation, and should be organized and tabulated to facilitate access to specific information.

The commissioning authority will make a site review within 10 months after substantial completion, along

with the contractor and all concerned subcontractors.

Functional tests and verification will be repeated in order to get the required information.

Commissioning authority will then have to make another report concerning this site review.

VI‐ List of expected work products

Commissioning intent, as mentioned earlier in this report is to verify that the project’s energy related systems

are installed, calibrated and perform according to the owner’s project requirements, basis of design and

construction documents and to provide the owner with a high level of assurance that the mechanical and

electrical systems have been installed in the prescribed manner, and operate within the capabilities of the

documented design and specified equipment capacities.

Therefore our mission will be to provide the owner, in our final commissioning report and our site review

within 10 months of occupancy, with an objective point of view of the actual state of MEP equipment.



VII‐ Testing equipment

It is be noted that all test equipment required for performing the specified tests shall be provided by

contractors. Any proprietary vendor specific test equipment shall be provided by that vendor or manufacturer.

Any portable or hand‐held setup / calibration devices required to initialize any control system shall be made

available by the control vendor (at no cost) to the commissioning authority.

The instrumentation shall meet the following requirements:

‐ Be of sufficient quality and accuracy to measure system performance within the tolerances required.

‐ Be calibrated with calibration tags permanently affixed to the instrument.

All items needed to undertake testing and verification as described in the attached annexes should be

provided by the contractor.

VIII‐ Commissioning process milestones, schedules

Commissioning milestones and schedules cannot be determined exactly for the time being, but will be

integrated to this report during future revisions once we receive the detailed construction planning.

The startup and testing of systems may proceed prior to final completion of systems. However, the

commissioning authority shall not perform checkout services that are the primary responsibility of the

contractor vendor in advance of their testing and checkout, whom in return are responsible to inform the

commissioning team once their systems are ready to be verified and tested.

Problems observed will be addressed immediately, responsible parties will be notified.

Contractor schedules and scheduling is the responsibility of the construction manager. The commissioning

authority shall provide commissioning scheduling information to the construction manager for review and

planning activities.

The commissioning process does not relieve any contractors from their obligations to complete all portions of

work in a satisfactory manner.

Throughout project construction, the following table including all systems to be commissioned will be

updated.

1 – Introduction:

The procedures stated in this document cover the activities in preliminary tests and

inspections, functional performance tests and the commissioning of newly completed electrical

installations.

The Contractor shall carry out the T & C works for LEED as detailed in this document.

2 – Objective of the T & C:

The objectives of the T & C works are:

To verify proper functioning of the equipment/system after installation.

To verify that the performance of the installed equipment/systems meet with the

specified design intent through a series of tests and adjustments.

To capture and record performance data of the whole installation as the baseline for

future operation and maintenance.

3 – Scope of the T & C Works:

3.1 – Preliminary Steps for Testing and Commissioning: Before carrying out T&C, the Contractor shall take the following steps:

a. Review approved shop drawings and equipment schedules; b. Check manufacturer’s operating instructions and statutory requirements; c. Physically inspect the installation and equipment to determine variations from designs

and/or specifications. d. Check individual components, e.g. key switches, control equipment, circuit breaker

status, etc. for proper position and settings for completeness of installation. e. Check inclusion of manufacturer’s typical equipment testing data or factors before T&C

of particular equipment.


3.2 – Tests & Inspections during Construction:

The purpose of these tests is to ensure that all components and systems are in a satisfactory

and safe condition before start up. Preliminary adjustment and setting of equipment at this

stage also be carried out at the same time to pave way for the functional performance tests.

Before carrying out any test, The Contractor shall ensure that the installation complies with all

relevant statutory requirements and regulations. The T & C works shall also comply with all site

safety regulatory requirements including but not limited to:

(i) IEC 60364 “ Electrical Installations of Buildings”

(ii) Electricity supply rules of the relevant power supply companies

Or other approved codes and standards.

3.3 – Functional Performance Tests:

The purpose of functional performance tests is to demonstrate that the equipment/installation

can meet the functional and performance requirements as specified in the General/Particular

specifications. Functional performance test should proceed from the testing of individual

components to the testing of different systems in the installation.

Any performance deficiencies revealed during the functional performance tests must be

evaluated to determine the cause and whether they are part of the contractual obligations.

After completion of the necessary corrective measures, the Contractor shall repeat the tests.

If any test cannot be completed because of circumstances that are beyond the control of the

Contractor, it shall be properly documented. The contractor shall resume his testing work

immediately upon the attainment of a suitable testing environment.

3.4 – Documentation and Deliverables:

All inspection and T & C results shall be recorded in the data record forms.

A functional performance test report covering all measured data, data sheets, and a comprehensive summary describing the operation of the system at the time of the functional performance tests shall be prepared and submitted. Deviations in performance from the General/Particular Specifications or the design intent should be recorded, with a description and analysis included.


4 – Testing and Commissioning (T & C) Procedure:

4.1 Tests and Inspections during Construction

For those tests to be carried out on different systems of the installation during construction to ensure their suitability for operating at the design conditions, certificates of such tests shall be issued together with certificates of any work tests. The tests and inspection shall include, but not limited to, the followings: (a) Visual inspection; (b) Earth electrode resistance; and (c) Continuity of protective conductor. (d) Voltage measurements. (e) Lux measurements.

Details of these tests shall be in accordance with relevant sections of this procedure.

4.2 Inspection and Test for Low Voltage Installations

4.2.1 Inspection before Test

A visual inspection shall be made to verify that the electrical installation /equipment as installed is correctly selected and erected and that there is no apparent damage. The visual inspection shall include a check on the following items, where appropriate: a. Adequacy of working space, access, and maintenance facilities; b. Connections of conductors; c. Identification of conductors; d. Adequacy of the sizes of conductor in relation to current carrying capacity and voltage

drop; e. Correct connections of all equipment with special attention to socket outlets, lamp

holders, isolators, switches, and protective conductors, f. Presence of appropriate devices for isolation and switching; g. Presence of diagrams, instructions and other similar information;

4.2.2 Sequence of Tests

The following items, where relevant, are to be tested preferably in the sequence indicated below:

a. Continuity of protective conductors, including main and supplementary equipotential bonding,

b. Earth electrode resistance,


c. Earth fault loop impedance, In the event of any test indicating failure to comply, that test and those preceding, the results of which may have been influenced by the fault indicated, shall be repeated after the fault has been rectified.

4.2.3 Conductor Continuity

Continuity of Protective Conductors Every protective conductor, including all conductors and any extraneous conductive parts used for equipotential bonding should be tested for continuity. The test should be made by connecting together the neutral and protective conductors at the mains position and checking between earth and neutral at every outlet by a continuity tester, which should show a reading near zero.

4.2.4 Earth Electrode Resistance

A proper earth electrode resistance tester should be used to measure earth electrode resistance. An alternating current at 50 Hz of a steady value is passed between the earth electrode T and an auxiliary earth electrode T1 placed at a separation distance recommended by the manufacturer of the tester but in any case should not be less than 20 metres away. A second auxiliary earth electrode T2, which may be a metal spike driven into the ground, is then inserted half‐way between T and T1, and the voltage drop between T and T2, divided by the current flowing between T and T1, gives a measured earth electrode resistance of earth electrode T. For an electrical installation having four or more earth electrodes which are installed more or less in line, following a general direction not exceeding 15� deviation and with separation between adjacent electrodes not less than the recommended distance by the manufacturer of the tester but in any case not less than 20 meters, these electrodes can be used in turn as the auxiliary electrodes for the purpose of measuring the earth electrode resistances. The following alternative method for measuring the earth electrode resistance may be used if the electricity supply is connected. A loop impedance tester should be connected between the phase conductor at the origin of the installation and the earth electrode with the test link open, and a test performed. This impedance reading could be treated as the electrode resistance.

4.2.5 Earth Fault Loop Resistance

The earth fault loop impedance should be measured by a phase‐earth loop tester with a scale calibrated in ohms.


The earth fault loop impedance should not exceed the requirements of applicable code. Before the test begins, it is essential to establish, by inspection, that the earthing conductor and all relevant earth connections are in place, and that the bonding connection to electricity supplier’s earthing facilities is disconnected. Measures should be taken, during the impedance tests especially when the earth leakage protective devices are effectively removed for the duration of the tests, to ensure that the installation is not being used other than by person(s) carrying out the tests.

4.4 Functional Test of System/Equipment

4.4.1 Circuitry Check

All circuits shall be verified through switching operation to ensure that the circuits are installed in accordance with the designated circuit. The tests shall include but not be limited to the following:

a. On/off switching of the lighting circuit to ensure that the lighting circuit is installed corresponding to the lighting switch, protective device and labeling;

b. Switching of the general power circuit to ensure that the circuit corresponds to the protective device such as RCD, RCBO and MCB, and that the protective device performs in accordance with the designated duty;

c. Switching of the main switch / isolator to ensure the corresponding circuit is properly controlled by the main switch / isolator;

d. Switching of all sub‐main and main distribution circuits, e.g. bus ducts, cable feeders, underground cables, etc. to ensure the correct isolation of the connected circuit;

e. Switching of all changeover switches to ensure the changing over sequence corresponds to the design criteria;

f. Ensuring all the protective devices perform properly against the designated circuit.

4.4.2 Lighting Installation

Lighting installation shall be tested in terms of its light quality and control as following: a. Before carrying out the lighting measurement and test, all luminaries shall be checked

against the specified color temperature, beaming angle of spot lamp and aiming angle for exterior floodlights.

b. The aiming angle of external lighting or planter lighting shall be commissioned so as not to create glare or any obstructive light to external environment.


c. Before commissioning and /or setting of lighting control devices which including but not limited to timer switch, occupancy sensor, photocell and infra‐red sensor, the Contractor shall submit commissioning /setting proposal for approval.

d. Illumination level of lighting installation for individual areas/rooms shall be measured to verify the light output. The Contractor shall submit the proposed locations and height levels for carrying out the measurement of illuminance level for approval before commencement of measurement. Presentation of the measurement result shall be in the form of marked up layout plan for the particular area.

e. Base on the measured illuminance results for individual areas/rooms, the lighting uniformity of the respective areas /rooms shall be evaluated in terms of minimum to average illuminance ratio.

f. All grouping of luminaries shall be tested by hand operation of the corresponding switches or timers.

g. For lighting installation with interface connection to building management system (BMS), or central control and monitoring system (CCMS) or similar central computer control system, the Contractor shall co‐ordinate with other contractors responsible for such computer control system, if required, to demonstrate proper control function of the lighting installation.

4.4.3 Digital Multifunction Power Meter

The digital multifunction power meter shall be tested to verify the measurement, recording and interfacing functions as required in the General Specification. Prior to the test for every digital multifunction power meter, the Contractor shall provide manufacturer’s calibration certificate for each meter for checking on the accuracy. The Contractor shall provide testing kit to verify the reading accuracy of the digital multifunction power meter. For installation of digital multifunction power meter with connection to building management system (BMS), or central control and monitoring system (CCMS) or similar central computer monitoring system, the Contractor shall co‐ordinate with other contractor responsible for such computer monitoring system, if required, to demonstrate proper functioning and interfacing of the meter. For installation of digital multifunction power meter without external connection to building management system or CCMS, the interface functions including digital and analogue output shall be tested by means of plugging in communication module provided by the Contractor. The replacement mechanism of the meter shall be tested. The test shall demonstrate that the replacement of the meter does not require the switching off of the respective switchgear.

1–General:

1.1–PurposeoftheTesting&CommissioningProceduresHaving already been inspected as materials and installed in their reserved location the purpose

of this document is to ensure that:

‐ The AHU(s) are in a good condition and operating properly.

‐ Airflows in relevant ducts & air terminals are as per design drawings.


‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐


Refer to Appendix A

1.3–ResponsibilityThe main contractor will carry out the testing and commissioning with the related supplier.

2–Tests&InspectionstobeCarriedOut:The following tests and inspections will be carried out and recorded on the relative forms.

2.1–VisualInspection:Before Fan operation, Visual Inspection shall be carried out to ensure that the material has no

defects and installation is proper. Refer to visual inspection checklist for fans.

2.2–OperationalTests:Before running the fan, make sure that all fire dampers, duct volume dampers, splitters

dampers and outlets dampers, splitters dampers and outlets dampers are fully opened. Run the

fan and check if it is giving the required design flow. Then proceed airflow‐balancing starting

with the terminals with least resistance & work towards the terminals with greater resistance.

The terminal with the greatest resistance might be the most remote one it the one that have a

lot of duct direction changes.


Using the Airflow Meter (Hood for ceiling diffusers and rotating vane for side grilles), airflow

rate can be measured at each terminal. Duct volume dampers & splitter dampers shall be

adjusted to distribute the required flow in the various branches. Airflow velocity in duct (Duct

Traverse reading) shall be measured by a Pitot Traverse; several velocities should be taken to

get the average velocity. Volumetric airflow rate can then be calculated by multiplying the final

average velocity by the duct area. Fan static pressure (inlet, outlet, total) shall be measured by

Micro‐Manometer. Fan & Motor speed, electric Current, Voltage etc…. Shall be measured as

well.

For AHU’s serving VAV’s units, system shall be balanced at maximum design data, and then

remeasured at simulated partial load conditions. Each VAV box will be considered as a small

independent system by itself.

All measurements and readings shall be recorded in the relevant performance sheets.

For AHU’s coils water balancing refer to (Secondary chilled and hot water systems).

2.5–ToleranceFor air system, the tolerances on terminals and fans are as follows:

1. Supply, return and exhaust fans shall not be less than 95%.

2. For any space the flow should be within – 5% and – 10%.

‐ Space with one outlet, the tolerance is as above.

‐ Space with two outlets, the tolerance is + or – 10%.

‐ Space with 3 outlets or more, the tolerances is + or – 10%.

3. Return and exhaust inlets, the tolerance is + or – 10%.

Refer to Appendix A




2.1–VisualInspectionWhen the installation of the Water Pumps, Piping, & Accessories is complete, a visual

inspection should be carried out to ensure that the workmanship is satisfactory, and that the

system complies with the approved design and project specifications. Checklists that should be

used with visual inspection for the system are included in this document.

2.2–PipePressureLeakTestWater Pipes lines shall all undergo hydraulic pressure leak test at 1.5 working pressure for 24

hours.

2.3–PipeFlushingProcessPipes should be cleaned and flushed in accordance with the method statement for flushing by

the specialist.


2.4–OperationalTestsAfter the flushing process of cooling water Pipes is complete, the system will be filled with clean treated water and air is scavenged out through automatic air vents and air relief valves. Cooling pumps are then operated to verify the operational performance by checking the actual measured performance against the design data via the following steps:

1. With the pump operating, assure that piping system. AHU's. FCU's are vented properly. 2. Connect a suitable differential pressure gauge across the suction and discharge pressure

test points of pumps. 3. Take measurements for voltage, current. & speed for pump motor. 4. Check the operation of variable frequency drive by closing partially the main valve. 5. With the pump running, close the discharge valve slowly for several minutes. 6. Determine the "Shut‐off" head and check against manufacturer's data for zero flow. 7. If the test shut‐off head does not coincide with the manufacturer's figure, draw a

corrected curve parallel to the manufacturer's curve starting from the measured shut‐off head.

8. Open discharge valve slowly to fully open position. 9. Record the total head with the D.P Gauge at full flow rate & read the actual flow from

the manufacturer's data, or from the corrected graph curve. If the flow is more than 5% above the design flow then regulate by closing slightly the globe valve.

10. If performance is inadequate refer to installation Contractor & Designer. 11. Record all readings & measurements in the pump performance test sheet attached in

this document.

After verifying the required pump flow, water balancing shall proceed as follows:

12. Check the operation of two/three ways valves. 13. Verify that the farthest FCU or AHU from the pump is receiving the correct design water

flow or more (by using the flow meter at the DRV of this unit) 14. Adjust the FCU's and AHU's flow rates by regulating the DRV's starting with the units of

least resistance and work towards the units with the greater resistance. 15. On cooling system and where three‐way motorized valves are used, balance the globe

valves at the bypass line to restrict the by‐ passed flow to 90% of the maximum value at the relevant coil.

16. Make a final check of pressures and flows of the pumps and terminal units. 17. Record all flow measurements corresponding to each FCU, AHU. HWST & HEX in the

flow balancing sheets attached in this document which are classified as per type of system control as chilled water system.

1–General:

1.1–PurposeoftheTesting&CommissioningProceduresHaving already been inspected as materials in their reserved locations, the purpose of this

document is to ensure that all Pumps, Piping, & Accessories are in a good condition and

operating properly.

Refer to Appendix A




2.1–VisualInspectionWhen the installation of the Water Pumps, Piping, & Accessories is complete, a visual

inspection should be carried out to ensure that the workmanship is satisfactory, and that the

system complies with the approved design and project specifications. Checklists that should be

used with visual inspection for the system are included in this document.

2.2–PipePressureLeakTestWater Pipes lines shall all undergo hydraulic pressure leak test at 1.5 working pressure for 24

hours.

2.3–PipeFlushingProcessPipes should be cleaned and flushed in accordance with the method statement for flushing by

the specialist.


2.4–OperationalTestsAfter the flushing process for water line is complete, the system will be filled clean water and

air is scavenged out through automatic air vents and air relief valves. The Pumps are then

operated to verify the operational performance by checking the actual measured performance

against the design data via the following steps:

1. Connect a suitable differential pressure gauge across the suction and discharge

pressure test points of pumps.

2. With the pump running, close the discharge valve slowly for several minutes. (Do not

close any valves in the discharge piping of a positive displacement pump).

3. Determine the “Shut‐off” head and check against manufacturer’s data for zero flow.

4. If measured shut‐off head does not coincide with the manufacturer’s figure. Draw a

corrected curve parallel to the manufacturer’s curve starting from the measured shut‐

off head.

5. Open discharge valve slowly to fully open position.

6. Record the total head with the D.P. Gauge at full flow rate & read the actual flow from

the manufacturer’s data, or from the corrected graph curve.

7. If total head of pump is higher than design data, the water flow will be lower than

designed. Solution will be prepared and submitted to the Engineer for approval.

8. If the total head of pump is less than design data, the water flow will be higher than

designed. Closing of the globe valve at the pump discharge will increase the pressure

drop of system and reduce the flow until reach 110% of the design flow. Motor current

shall be checked and be kept within the nameplate indication.

9. Take measurements for voltage, current, & speed for pump motor.

10. Record all readings & measurements in the pump performance test sheet attached in

this document.

Once pumps are tested, overall domestic water system will be operated tested as per

procedure described in the test sheet enclosed to this document.


2.5–ToleranceThe tolerance on the performance of pumps is as per specification plus/minus 5%.

fan and check if it is giving the required design flow. Then proceed airflow‐balancing starting

with the terminals with least resistance & work towards the terminals with greater resistance.

The terminal with the greatest resistance might be the most remote one or the one that have a

lot of duct direction changes.


Using the Airflow Meter (Hood for ceiling diffusers and rotating vane for side grilles), airflow

rate can be measured at each terminal. Duct volume dampers & splitter dampers shall be

adjusted to distribute the required flow in the various branches. Airflow velocity in duct (Duct

Traverse reading) shall be measured by a Pitot Traverse; several velocities should be taken to

get the average velocity. Volumetric airflow rate can then be calculated by multiplying the final

average velocity by the duct area. Fan static pressure (inlet, outlet, total) shall be measured by

Micro‐Manometer. Fan & Motor speed, electric Current, Voltage etc…. Shall be measured as

well.


1. Supply, return and exhaust fans shall not be less than 95%.
