Building Commissioning Services

What is LEED Commissioning?

Commissioning is a procedure of ensuring a building’s systems working as intended. It is third-party verification to understand energy using and consuming systems are operating optimally. This verification includes equipment installation, testing, operation and maintenance stages. Projects targeting LEED Certification must meet with the minimum commissioning requirements. This sets a minimum benchmark for energy efficiency, reduction of CO2 emissions, and indoor environmental quality.

Buildings nowadays are developed by implementing the most innovative technologies possible. It is extremely important the installed equipment and systems are functioning with optimum performance. Otherwise, the efforts spent in design is would be useless. The main purpose of commissioning is ensuring appropriate installation and verification of the building systems. Usually in accordance with the “Owner Project Requirements” and “Basis of Design” documents. Any issues that identified may cause inefficient building operations reported to the owner. The problems are are resolved by regular communication of CxA, building owner, contractors and other commissioning team members. USGBC has specified certain deliverables to make sure that Commissioning process is applied with a certain standard. Commissioning is not only mandatory, but also the integral part of LEED Consulting Services to achieve certification.

Benefits of Commissioning

There are numerous benefits of commissioning process and the most important ones:

  • Reduces operational expenses
  • Ensures offices staff know how to work key building systems
  • Recognizes and adjust mistakes on missing or inefficiently installed equipment
  • Avoids inhabitant complaints and callbacks
  • Solves indoor air quality and thermal relief issues
  • Avoids untimely hardware failure

Scope of LEED Commissioning 

LEED Commissioned systemsLEED Commissioning includes review of the following building systems:

  • HVAC & R  systems (Heating, Ventilation, Air-conditioning, and Refrigeration)
  • Lighting system
  • Lighting and daylighting controls
  • Domestic hot water systems
  • Renewable energy systems

 

LEED Fundamental Commissioning 

The LEED Fundamental Commissioning includes following activities:

  • Owner designates an experienced professional not involved in project design as the Commissioning Authority (CxA) to manage the commissioning process.
  • Owner is required to document  the Owner’s Project Requirements (OPR).
  • The design team develops the Basis of Design (BOD) document.
  • The Commissioning Authority reviews OPR and BOD  for the accurateness and clarity.
  • Commissioning Authority develops and incorporates commissioning specs into the construction documentation.
  • Commissioning Authority develops and implements a Cx plan.
  • CxA verifies the actual performance and installation of energy using and consuming systems.
  • CxA delivers a final Commissioning Report.

For LEED NC, CI, and Schools projects, LEED Fundamental Commissioning is a prerequisite.

LEED Enhanced Commissioning 

LEED system has the additional option to achieve an extra point beyond the Fundamental Commissioning. The Enhanced Commissioning credit has other extra requirements:

  • Designating an experienced individual as CxA, will act independently, to manage the design review process before the start of the construction stage.
  • It is required conducting at least one design review by CxA. Design review will include verification of  OPR, and BOD as well as other project documents. It is developed prior to mid-construction documents stage. Also, the back-check of the review comments is required in subsequent design submissions.
  • Commissioning Authority reviews the contractor submittals relevant to the commissioned systems for the congruence with OPR and BOD.
  • CxA develops the systems manual that shows how the systems operate. This guide will later be used by the maintenance and operation staff.
  • CxA verifies that training of the operating personnel is properly completed.
  • CxA reviews the building operations within 10 months after substantial completion. During this verification O&M staff, owners representative accompanies to the CxA. A plan for the resolution of commissioning issues is developed.

What qualities LEED requires for the Commissioning Authority?

CxA should have an extensive understanding the goals and deliverables of the commissioning process. USGBC has clearly defined the LEED Commissioning requirements and the qualities that CxA should have. CxA must document previous commissioning work experience with at least two projects. These projects must have similar in terms of function and size. CxA’s experience must involve to those projects from the early design along with the minimum 10 months of occupancy. CxA can be a qualified staff of owner, third party consultant, or an employee of the disinterested contractor or design team. If the building project is smaller than 20,000 sq.ft (approximately 1860 sq.mt), the CxA can be a qualified professional of the contractor or design team. CxA always reports his findings straight to the owner.
