Commissioning and Audit services for Green Building certification

Provides commissioning and Audit services, as per green building rating system to gain the credits under Energy and Atmosphere (E&A) criteria. Apart from the Third party Commissioning we also provides comprehensive commissioning services.

The commissioning process is a highly effective method to improve the performance of building systems and equipment.

Green Building Commissioning Services

Fundamental commissioning

The overall intent of fundamental building systems commissioning is to ensure that all building elements and systems are designed, installed and calibrated to operate as intended.

2 Overall scope of fundamental building systems commissioning The overall scope of fundamental building systems commissioning is as follows: Develop a commissioning plan for all equipment and systems (like HVAC, Pumps, Cooling tower, Heating systems, BMS, Lighting, etc., Review design intent and basis of design documentation for each of the equipment and systems Verify inclusion of commissioning requirements in the tender, installation and commissioning documents in accordance with the commissioning plan Verify installation, functional performance, training and documentation for each of the equipment/system Prepare commissioning report

The detailed scope of work is as follows

2.1 Responsibility of commissioning authority the commissioning authority is responsible for implementation of all fundamental commissioning procedures. The commissioning authority would carry out the following: Overall supervision of commissioning process of equipment/systems Report to the owner regarding the performance of the building system/equipment Introduce standard procedures and strategies to ensure implementation of owner’s requirement

2.2 Document the owner’s requirements and basis of design the commissioning authority would carry out the following: Document and vet owner’s requirements and basis of design for all building systems/equipment to meet LEED India specifications. Typically the systems include the following: HVAC system, Lighting system, energy efficiency and water efficiency, Indoor air quality and overall environmental responsive of the facility, etc. The basis of design should consider occupancy, climatic assumptions, load fluctuations, space requirements, codes & standards.

2.3 Include commissioning requirements in the construction documents The CA will ensure incorporating the commissioning requirements in each of the contract documents and should clearly describe the following: The scope of commissioning Feature and systems to be commissioned Requirements of inspection, start-up, testing, training, O&M documentation and warranty period activities, commissioning documentation requirements, schedule and rigor & scope of testing.

2.4 Create a commissioning plan A detailed commissioning plan should be prepared at the design stage. In case, decision to go for the LEED India rating has been made after the designed phase, the commissioning plan can be completed prior to installation of equipment / systems. To satisfy the LEED prerequisite the commissioning plan should capture the following: A list of all commissioned features and system in the project A brief overview of the commissioning process List of parties involved the commissioning process and their responsibilities A description of how commissioning plan has been communicated and managed Commissioning procedure of each of equipment / system and briefly outline how this would be achieved. This should capture procedures for start-up, testing, training, O & M documentation and warranty period activities. Activity schedule Description of rigor and scope of testing for each of the system

2.5 Verify installation, functional performance, training and documentation The commissioning authority must complete the following on each commissioned component, equipment, systems or feature: Installation observation: The commissioning authority must verify all equipment/system/component to ensure that they are properly installed as per the direction of manufacturer. Start-up & checkout: Ensure that the contractor completes the start-up and initial checkups of all items. The results must be clearly documented according to manufacturer’s written instructions. Sampling: The commissioning authority by appropriate sampling techniques will verify that all control systems, actuators are functioning as intended. Functional testing: Functional testing should be documented either by the Contractor’s Test Engineer with review and approval by commissioning authority. After initial check, test sequences and control strategies such as start-up, shutdown, unoccupied and manual modes, modulation up and down the unit’s range of capacity, power failure, alarms, response of the backup equipment and interlocking of other equipment. All large equipment should be individually tested. Small units can be tested based on a specific sampling strategy. Heating equipment to be tested during winter and air-conditioning equipment during summer to demonstrate performance close to design conditions. Training: The commissioning authority should ensure that proper training was conducted on all commissioned equipment / system. The training should cover the following: Design intent of the system, Use of O&M manual Review of control drawings and schematics Startup, handling seasonal variations, trouble shooting and alarms Optimizing energy performance Health and safety issues Special maintenance and replacement sources Training on how the systems is environmentally responsive O&M Manual: Commissioning authority must review the O&M manuals provided by the suppliers. The O&M data sheets must be bound, labeled with section breaks for easy access. The manual should contain vendor name, address, telephone number, installation contractor details, O&M procedure, etc. The manual should include instructions for maintenance and operation, as built controls drawings and narratives for various modes of operation.

2.6 Commissioning report A comprehensive commissioning report must be prepared and presented to the owner by the commissioning authority after completion of all functional tests. The following are the typical component of commissioning report: Design intent Meeting of specification Ensuring proper installation Functional performance and efficiency O & M documentation Operator training The commissioning report must also contain list of outstanding commissioning issues and schedule of any testing that has been scheduled for a later date. All completed functional tests should be listed in an appendix to the commissioning report.
