Commissioning Plan 1

Introduction

A. DEFINITION OF COMMISSIONING

Commissioning is a process for achieving, verifying, and documenting that the performance of a building and its various systems meets the design intent and the owner's operational needs. Commissioning tests the operation of the equipment and buildings systems to ensure that they operate as designed and can satisfactorily meet the needs of the building throughout the entire range of operating conditions.

B. COMMISSIONING GOAL

The goal of the commissioning process is to verify for the owner that the mechanical, electrical, plumbing, fire protection, and controls systems function interactively in compliance with the project intent, and to facilitate the orderly and efficient transfer of the systems to the Client’s Operations and Maintenance personnel.

Commissioning also documents system performance parameters for fine-tuning control sequences and operational procedures, and to facilitate future troubleshooting.

Commissioning is not intended to be a testing or inspection function that is redundant with respect to the contractor’s obligations for testing and proof of performance.

C. PURPOSE OF THE COMMISSIONING PLAN

The Commissioning Plan is based on the understanding that it is the desire, as well as the obligation, of the Construction Manager and the subcontractors to provide systems that function in accordance with the intent of the project documents. The project goal is to provide building systems that are interactively functional with respect to one another. It is the Commissioning Agent's (CA) role to develop and manage the commissioning process as a means of verifying that this goal is accomplished, within the limits of the contract, for the systems that are included in the Commissioning Plan.

The purpose of the Commissioning Plan is to outline the scope and format of the commissioning process for this project. As commissioning is a dynamic process, the contents of this plan may evolve as the project proceeds.

Commissioning Plan 2

Defining the Commissioning Team

A. TEAM MEMBER RESPONSIBILITIES

A successful commissioning effort results in a successful project. Therefore, the participation and cooperation of the Owner and all divisions of the construction and design teams is recognized as a critical component of the commissioning process. The members of the Commissioning Team play the following roles in the commissioning process.

1. Owner

The commissioning team relies on the owner's representative for owner input regarding the commissioning process. Key input includes:

a. Owner's Representative (OR)

• The Client’s Project Manager and O&M Representative review the Commissioning Plan, Schedule, and the Functional Test Procedures at their option. This review is part of training for the O&M personnel who will operate the building. Provide input required to develop final plans and procedures that all team members accept as a fair means of compliance with the commissioning goal and the project contract.

• As schedules permit, witness start-up of major equipment and the Point-to-Point testing by the controls contractor.

• As schedules permit, witness demonstration of compliance with Functional Test Procedures.

• Provide Owner input for the fine tuning or trouble-shooting of system performance if either of these measures become necessary.

Commissioning Plan 10

The Commissioning Process

The goal of commissioning, as stated on page 1, will be realized through the following process. The process is sequential, although some activities may occur simultaneously. For example, there may be duct pressure testing going on in one area and point-to-point in another, even though pressure testing should be done before point-to-point in the same area. Likewise, the point-to-point in an area needs to be complete before balancing of that area; however the balancer can be balancing in one area while point-to-point is going on in another area.

A. MEETINGS

Periodic commissioning meetings will be held. These meetings will cover commissioning and test and balance issues only. General construction issues are to be addressed in the regular construction meetings. Until startup those meetings will coincide with CA site investigation visits. The meetings will cover items found during the site visits, will monitor progress of functional test writing and other pretest activities. During pre-commissioning checking and startup those meetings will be every other week. During testing the meetings will be weekly or as deemed appropriate.

These meetings will be the primary venue for discussing issues relating to commissioning. It is important that the appropriate individuals attend.

B. COMMUNICATION

Between meetings, it is appropriate to communicate via mail, e-mail, phone, or face-to face. All pertinent non-written communications will be documented with a memo. The commissioning agent will direct all of their communications through the owner with copies to the appropriate contractors and designers. Word processing documents will be in Microsoft Office XP Word and spreadsheets in Excel.

C. SUBMITTAL REVIEW

The Commissioning Agent will review all mechanical and electrical submittals that pertain to the systems to be commissioned as outlined in section 4. This review will allow the CA to gather information pertinent to the production of the Pre-Functional Test checklists and the Functional Performance Tests. This review does NOT supplant the review required of the design professionals.

D. SITE INVESTIGATIONS

The inspection of the quality of construction is the Design Team's responsibility. The Design Team shall provide for the routine inspection of the construction site to

Commissioning Plan 11 ensure that the installation meets the standards of the design specifications, plans and good construction practices.

The CA shall make periodic inspections of the job during the construction phase.

The CA’s inspection shall concentrate on those systems to be commissioned with emphasis on equipment accessibility, control sensor locations, ability to be properly balanced and ability to be commissioned. The CA’s site inspection will also review how well the construction lends itself to the operation and maintenance by the

Owner’s personnel. During these inspections, any problems identified shall be brought to the Owner’s attention. The Owner shall then review the problem with the

Design Team and Contractors and a solution will be developed. The Contractor is responsible for correction of contract deficiencies identified during site investigations. The Design Team is responsible for correction of design deficiencies found during site investigations.

E. SYSTEM START-UP

As described above under team member responsibilities and in the specifications, it is each subcontractor’s responsibility to start-up the equipment in their portion of the specifications. As part of start-up, the appropriate subcontractor will fill out their respective Pre-Functional Checklists (PFC) and submit them to the CA. A sample of a PFC is in the appendix of this plan. Because the checklists are equipment and system specific, production of these documents will take place after the equipment submittals are in. This task will be tracked by the CA and Construction Manager.

F. POINT-TO-POINT

It is suggested that the controls contractor perform point-to-point testing of all control components, regardless of whether they are functionally tested. The procedures and methods for this testing will be submitted for approval. The tests will be witnessed by the Owner, at their option. The CA will verify that all sensors have been calibrated and all actuators (damper and valve) have been adjusted for full open and full closed. All pilot positioners will be checked for proper setup. All airflow stations that are used for control will be verified.

G. TESTING AND BALANCING

As the contractors complete systems, the TAB contractor will start balancing those systems. All systems do not have to be complete before the balancer starts. It is very useful, and therefore desirable for the commissioning agent to have the balance data while performing the functional testing. Copies of balancing data taken each day will be made available to the commissioning agent.

H. FUNCTIONAL PERFORMANCE TESTING

Effective functional testing cannot begin until the contractors have completed all portions of their work and the systems are fully operational. This includes testing, start up, controls, and test and balance.

Commissioning Plan 12

The actual Functional Performance Test (FPT) procedure will be performed in compliance with the project specifications by the appropriate contractor(s) under the direction of the CA. A sample of a FPT procedure is in the appendix of this plan.

Because the procedures are equipment and system specific, production of these documents will take place after the equipment submittals are in.

The flow chart on page 14 depicts the implementation procedure for pre-functional and functional testing.

I. COMMISSIONING REPORTING AND DEFICIENCY TRACKING

Throughout the process, items requiring attention will be reported and tracked via an issues log. An example of this form can be found in the Appendix. Issue log items will be treated like any other punch list, with room on the report for answers.

The issues log will become part of the final Commissioning O&M manual.

J. TRAINING

As described in the specifications, each contractor is responsible for training of equipment and systems in their respective sections. Each contractor will submit a training plan to the CA for review. This plan will include the design intent of the equipment or system, use of the O&M manuals, review of controls, interaction with other systems, adjustments and optimizing methods for energy conservation, relevant health and safety issues, special maintenance and replacement sources, and tenant interaction issues. The Construction Manager is responsible for scheduling the training. The CM will submit a schedule to the CA for review.

K. O&M DOCUMENTATION

As described in the specifications, each contractor is responsible for submitting operation and maintenance information for each piece of equipment and/or system in their respective sections. The O&M data shall include: instructions for installation, maintenance, replacement, start-up, special maintenance and replacement sources, parts list, list of special tools, performance data (including fan and pump curves), and warranty information.

The controls O&M data shall include: as-built documentation package that includes a narrative for normal operation, shutdown, unoccupied operation, seasonal changeover, manual operation, controls setup and programming, troubleshooting, alarms, control drawings, and schematics and final sequences of operation.

This information is expected to be project specific.

Space Use

The total building area is 15,800 S.F.

There are 5 exterior entrances, 7 individual offices, 2 sets of men’s and women’s bathrooms, 4 conference rooms, 6 huddle rooms, 1 break‐room, a lobby and reception area, 4 large open office spaces, 8 storage areas, 1 mailroom, and 4 utility spaces.

2.2 -REDUNDANCY

A ground source variable refrigerant volume (VRV) heat recovery system with two, 14 nominal ton modules will provide the heating and cooling for the new building. The modules share a common refrigerant line. In the event of a failure of one module, the functioning VRV heat recovery module will continue to operate, providing a reduced capacity for the entire building.

The fan coil units served by the VRV heat recovery module are small, modular, and can be installed without the use of a crane. Parts or replacement fan coils are readily available by local suppliers pending a failure. Failure of an individual fan coil will likely provide undesirable space temperatures, but will not have a significant negative systemic effect if there is a failure.

A geothermal loop will be installed to serve the water‐cooled VRV heat recovery system. The geothermal loop consists of piping running in vertical boreholes that allows heat rejection or absorption to and from the earth. There will be two geothermal loop pumps sized at 100% flow each to provide 100% redundancy.

A dedicated outdoor air processing fan coil unit will provide tempered ventilation air to the building, ducting it directly to the fan coil units’ return ductwork or to the fan coil unit. There is no redundancy for this system. Short term failure of this component is not expected to have a significant impact on health or comfort. Other means of natural ventilation can be utilized (open windows, doors) if desired and weather is favorable.

2.3 DIVERSITY

Space Zoning

The building was zoned for temperature control based on specific thermal loading (perimeter or interior space, directional orientation of perimeter walls, and use of the space). Specific use areas (i.e.

conference rooms) are on their own separate zones. Interior spaces without exterior walls are zoned separately where practical. Hallways will be served from adjacent spaces. The communications room is conditioned with the same VRV system as the rest of the building to reduce the number of systems to maintain.

Mechanical and electrical spaces will be indirectly conditioned through exhaust airflow.

2.4 - OCCUPANCY

Mechanical ventilation rates are determined from Table 403.3 of the IMC. Occupancy densities are summarized below.

2.5 -OPERATIONS

The office spaces and conference rooms will be considered occupied 12 hours/day, 5 days/week, 52 weeks/ year. Conference Room spaces may be occupied outside of these days/hours for special events.

However, in the load calculations and energy model, diversity is accounted for in the conference rooms due to the variable frequency of use.

2.6 - NARRATIVES

Variable Refrigerant Flow (VRV) Heat Recovery System & Fan Coil Units The ground source VRV heat recovery system sends refrigerant in various states throughout the building between VRV heat recovery modules with compressors to fan coil units via refrigerant piping.

Branch selector boxes are used as an intermediate equipment between the modules and fan coils to allow simultaneous heating and cooling and the recovery of heat. This system utilizes three refrigerant lines between the modules and branch selector boxes. Two refrigerant lines are used between The refrigerant heat recovery units have variable speed DC compressors, to match the system demand with equipment output. This helps increase system efficiency, particularly at part load performance.

The ground source refrigerant heat recovery units are connected to a geothermal water loop that consists of X vertical boreholes, each approximately 350’ deep, with piping and pumps to circulate a water/glycol solution through the loop to reject or absorb heat from the earth, depending on the conditions. The pumps shall utilize an EC motor for high efficiency during reduced demand conditions.

The VRV controller will modulate ground source pumps to maximize efficiency of the system dependent on flow rate.

This project utilizes two types of fan coil units. Zones that serve one room are served by one (or more) ceiling cassettes. Zones that serve more than one room are served by ducted fan coil units. Electronic expansion valves vary the refrigerant flow to the fan coil units based upon the zone load as sensed by zone thermostats. Cassette type fan coil units automatically sense occupancy of the zone and will operate with reduced ventilation airflow rates and setback temperatures when unoccupied. Filters for the fan coils will be accessible in the occupied space. Ceiling cassette type fan coils shall have washable

& reusable filters. Ducted fan coils shall utilize filtered return air grilles.

Energy Recovery Ventilator (ERV) An ERV uses an enthalpy exchange medium (wheel or core) to transfer sensible and latent heat from the building exhaust to the building ventilation air. This reduces ventilation conditioning requirements and equipment size. The ERV provides tempered ventilation air to each fan coil unit or return air ductwork at a constant rate during the occupied hours, assuring proper ventilation of the occupied spaces. During favorable outdoor conditions, the ERV can cease heat transfer and provide economizing, or “free cooling”.
