LEED Commissioning

GREYHAWK provides commissioning services to support owner’s seeking LEED (Leadership in Energy and Environmental Design) certification of their projects. Our services support the certification process and result in reduced energy and carbon emissions and improved comfort conditions. Our engineers work in the field, not the office. Utilizing real-world experience, we find low-cost, easy-to-implement solutions that deliver impressive results.

Fundamental Commissioning is sometimes referred to as basic commissioning and is defined by LEED EA Prerequisite 1. Any building project seeking LEED certification must include “fundamental commissioning” of the following systems:

  • Heating, ventilating, air-conditioning and refrigeration (HVAC&R) and associated controls
  • Lighting and day-lighting controls
  • Domestic hot water systems
  • Renewable energy systems

Fundamental commissioning may be performed on new construction or large renovation or addition projects.

Enhanced Commissioning is defined by LEED EA Credit 3 and includes all of the components of Fundamental Commissioning with added participation during the design development phase of the project and post-construction follow-up. An important enhanced commissioning deliverable is the Systems Manual. GREYHAWK will work with the project team, including the owner, the design professionals and the contractors to prepare a comprehensive Systems Manual that incorporates O&M manuals, preventative maintenance guidelines and schedules, as-built sequences of operation and control drawings and system operating instructions.

For LEED certified buildings, the commissioning process must begin early during the design phase of the project. It includes the development of the owner’s project requirements (OPR), ensuring that the design professionals have developed a basis-of-design (BOD) for each system that reflects the OPR and review of design documents.
