Projects seeking LEED certification are now required to do so through LEED V4’s new path. That’s right, LEED 2009 (aka LEED v3) is no longer available for registration. There are numerous changes to the requirements of certification, however the focus of this article is on the Fundamental Commissioning and Verification prerequisites.
Prior to LEED V4, LEED 2009 required Commissioning only on the HVAC, domestic hot water, lighting controls and renewable energy systems. This has now been expanded to include ALL plumbing systems such as drain, waste, vent and domestic cold water systems; and ALL electrical systems including distribution, panel boards, emergency generators, and UPS systems.
The owner and architect should be aware that this is going to drive the cost of commissioning up significantly; not only the expense of hiring a 3rd party commissioning entity, but the increase in plumbing and electrical contractors’ bids to support this added effort. The contractors will realize that they’ll be required to attend more meetings, fill out more documentation, and participate in more functional performance verification testing.
In addition, this will change the dynamics of the overall project construction schedule for the owner and general contractor as the increased commissioning effort will take more time to complete. The estimated price increase will be a minimum of 30% for the cost to acquire a commissioning entity, and doubles the cost of commissioning for the plumbing and electrical contractors compared to that of LEED 2009. These costs will be passed on.
Please join us in congratulating our newest Mechanical Principal, Calina Ferraro!

Over time, a building’s HVAC system will stray from design intent through manual overrides or degradation of equipment. Issues can also arise if the building has gone through changes to the structure, zoning, design or HVAC system. All too often, repairs and modifications are done without consideration of the building and system as a whole, resulting in deep-seeded comfort and efficiency issues. The Randall Lamb Commissioning Group specializes in identifying and resolving these types of HVAC issues.
Our Team will investigate the issue, discover the cause and establish a path to resolution. If the issues are complicated in nature and lead to capital improvements, Randall Lamb will establish a commissioning process whereby all parties involved will be guided through a thorough quality control commissioning and verification process that results in a comfortable, efficient facility.
