Types of building commissioning include fundamental commissioning, retro-commissioning, on-going commissioning, and enhance commissioning.
Fundamental commissioning basically entails a basic quality assurance process of ensuring that energy systems are designed, installed and calibrated to function as intended in the OPR. If you want to take your building for LEED rating system, fundamental commissioning is a mandatory prerequisite. It is not an extensive process at all. New York Engineers can quickly provide this elementary commissioning of buildings.
Enhanced commissioning is more extensive than fundamental commissioning. This type of commissioning is not really mandatory if you want to acquire LEED rating system credit. In enhanced commissioning, our engineers get involved from the early stages of the design process to ensure that all systems are incorporated as per your plan. Where necessary we will give our recommendations on how you can optimize these systems.
After undertaking enhanced commissioning, we will revisit your building after 10 months just before your warranty expires in 12 months period to ensure that everything is still intact and in a good operational condition.
Our commission entails the following:
- A review of the owner’s project requirements and the basis of design
- Drafting of commissioning scope in construction documents
- Review of construction documents when the building is almost 95% complete
- Development of operations and maintenance manual
- A review of contractor submittals
- Re-commissioning of energy systems 10 months of occupancy
This type of building commissioning is best suited for existing buildings but it’s essentially the same as commissioning of a new building. Our engineer will review the available building systems against the original owner’s project requirements. Cost-wise, retro-commissioning is relatively expensive compared to the commissioning of a new building.
While reviewing the current systems, we will take into account at least a year’s cost of utility bills. Our goal is to optimize the systems so that you can save enormous costs in maintenance and energy. Our retro-commissioning will highlight the deficiencies in your current systems and flag them for maintenance. We provide an all-inclusive package where we can design, install and maintain mechanical and electrical systems.
The benefits of retro-commissioning include the following:
- Optimized building systems
- Reduced operational and maintenance costs
- Improved functionality of the equipment
- Lengthened building’s life cycle
- Mitigation of underlying problems
- Correcting of construction defects that occurred during design or construction
- Improving overall performance
New York Engineers excels in retro-commissioning of all types of building and building systems. We are the best in reviewing existing structures and recommending the best solutions for them.
You may wish to extend your building or add new equipment. Such an attempt may change the entire performance of your building and may also affect occupant conveniences. If a certain HVAC was designed for your initial design, for example, upon expansion it may not be sufficient to satisfy a new square area.
Recommissioning helps re-optimize building systems. This phase is best suited for buildings that have been in operation for several years and their equipment has been changed along the way. Our recommissioning process will create a balance with the systems. We still refer to the original owner’s project requirements when undertaking this process. If need be, we will recommend adjusting the systems or correcting underlying issues.
Ongoing commissioning, as the name says, it is continuous commissioning which is done at regular intervals. It is in other words referred to as the ongoing retro-commissioning wherein our engineer will revisit your apartment at specific time intervals to conduct commissioning. The number of time intervals depends on the building type. Typically, it can be once in a five year period.
Ongoing commissioning is actually beneficial to the building as it ensures that later additions of equipment are covered and if insufficient then the owner can adjust the systems. Our professional engineer delegated to do ongoing retro-commissioning will study your metering and analyze energy usage to compare it with the expected consumption as highlighted in the OPR.
Upon undertaking ongoing commissioning, we will continually update your commissioning plan and recommend changes where needed. We always keep our eyes focused on the Basis of Design and Owner’s Project Requirements. Furthermore, we will retrain your staff on how to operate updated systems.
