PROFESSIONAL SERVICES

First, and foremost, CxGBS’ focus is to be the owner’s advocate. We provide guidance and technical assistance to owners and their project teams, utilizing our Holistic Commissioning® process to create sustainable, high performance facilities. Our recommendations during design are based on meeting the Owner’s Project Requirements (OPR) with realistic, cost-efficient solutions using proven techniques. Our “holistic” approach, and execution improves delivery efficiency, reduces team risks and warranty call-backs, and assists the building owner and project team in achieving their defined goals.

Indefinite Delivery, Indefinite Quality (IDIQ) contracts are a clear indicator that a client has instilled a high level of confidence in your ability to perform the work they need done. CxGBS is proud to be a current IDIQ holder for the Atlanta Public School System, Georgia Institute of Technology, Mississippi Bureau of Buildings, National Park Service, and the Tennessee Valley Authority (TVA.)

HOLISTIC COMMISSIONING® (HCx)

Holistic Commissioning is a comprehensive process that goes beyond the traditional industry model by not only addressing the interaction between the building’s mechanical, electrical, and plumbing systems, but also including the building’s exterior envelope (enclosure), sustainability goals, and unique project-specific requirements.

Holistic Commissioning provides the greatest benefit when started in predesign because it allows implementation of high performance strategies at their lowest possible cost and establishes the foundation for maintaining and improving performance for the life of the building. Implementing Holistic Commissioning at an existing facility also provides significant financial returns raising occupant satisfaction, improving operational efficiency, and environmental stewardship for both new and existing facilities. Holistic Commissioning provides the tools owners and their staff need to increase financial rate of return for the facility.

The differences between commissioning and Holistic Commissioning is the difference between a snap shot in time and a continuous evaluation of the facility’s performance for an extended period. The Holistic Commissioning process does not end with testing the buildings performance at the end of construction or modifications to the facility. Holistic Commissioning examines the performance of the building over extended periods of time identifying opportunities to save money, increase operational efficiency and reliability of building systems that lower operational costs and increase the owner’s bottom line.

Retro-Commissioning (RCx)
Retro-commissioning is the application of the commissioning process to existing buildings, a process that seeks to improve how building equipment and systems function together. Retro-commissioning can often resolve problems that occurred during design or construction or address problems that have developed throughout the building’s life. Retro-commissioning improves a building’s operations and maintenance (O&M) procedures to enhance overall building performance.

Fundamental Commissioning | Enhanced Commissioning
Fundamental and Enhanced Commissioning are the commissioning processes for LEED Certification. Fundamental Commissioning is a prerequisite required under the LEED Rating Systems and is construction phase only, addressing MEP systems, lighting controls, and alternative energy systems. Enhanced Commissioning includes design phase, construction phase, and warranty phase, and includes O&M training as well as the delivery of a Systems Manual.

Building Enclosure Commissioning (BECx)
The building enclosure is a key component of healthy high-performing buildings as its design determines ability to keep the weather out; introduction of sufficient quantities of daylight to offset the need for artificial lighting; sizing of heating, ventilation, and air conditioning systems, and the total cost of operation. In addition to the building enclosure assemblies (roof, fenestration, exterior above grade and subterranean wall assemblies) building enclosure commissioning includes interaction between the building envelope and HVAC (heating, ventilation, and air conditioning) systems.

Monitoring Based Commissioning (MBCx)
Utilizing information technology to collect and analyze building performance data, CxGBS’s ongoing monitoring based commissioning is one of the most important phases of the commissioning process. It provides the data necessary for tracking facility performance by identifying the factors that impact costs, building performance and occupant satisfaction. Ongoing monitoring based commissioning can quickly pinpoint systems’ and components’ performance degradation. Doing so facilitates reliability centered maintenance and improves O&M staff efficiency by quickly providing diagnostic analysis in real time, which can significantly reduce troubleshooting efforts.

ENERGY AUDITS

CxGBS provides investigation and analysis of facilities to determine current energy efficiency of a building and identify potential improvements at the level required by the client.

Our knowledge of design, construction, and operation of the building systems enables us to recognize the cause of problems, identify contributing factors, and provide solutions to increase building efficiency. CxGBS follows ASHRAE Energy Audits (Levels I, II, III) protocol to meet a client’s needs.

SUSTAINABLE DESIGN AND OPERATION CONSULTING INCLUDING LEED®

CxGBS professionals document owners’ goals and requirements and show how sustainable principles can blend with stated objectives to set the foundation for integrated design and project delivery.

Our experienced staff members work in collaboration with the project teams to identify high-performing building concepts that are realistic and cost effective, and we provide life cycle and cost benefit analyses of various approaches to help teams select the most appropriate products, materials, and design alternatives.

With a 100% certification success rate, CxGBS is a recognized national leader in application of LEED principles. With many years spent as Technical Advisors to the US Green Building Council (USGBC) and Green Business Certification Institute (GBCI), we assist owners and teams in successfully integrating sustainable, healthy, and high-performing building principles into their projects. We are proud to have multiple LEED “firsts” in our experience: first office building in the southeast, first middle school, first theater and first carpet recycling plant.

BUILDING CONDITION ASSESSMENTS

To assist our clients in the evaluation of their assets, CxGBS provides building evaluation report services.

Traditional building evaluation reports provide detailed descriptions of the overall facility and systems such as grounds, building exterior, building interior, universal access, structural systems, mechanical systems, electrical systems, fire protection systems, and elevators. CxGBS adds projected energy costs to provide a more comprehensive cost of ownership when purchasing or operating a building.

ENERGY MODELING

Energy Modeling is a software simulation model that calculates a proposed design’s predicted energy consumption and costs. CxGBS staff has been performing energy modeling since 1980 on thousands of buildings ranging from custom residential to high-tech research laboratories and manufacturing facilities.

Our experience is in both new and existing buildings, providing owners with economic comparisons associated with design trade-offs, all while keeping projects in budget. Because of our extensive Energy Modeling experience, we are also able to afford our clients the added benefit of estimating energy usages during project design charrettes that are very close to the predicted energy usages well-developed energy models provide.

FORENSIC INVESTIGATION

Building forensics is the science and art of identifying the causes of problems affecting buildings, such as material deterioration, mold, moisture intrusion, poor indoor environmental quality, and high utility consumption.

CxGBS offers investigative services and cost-effective remedial recommendations that can significantly reduce the risk of recurrence. With our knowledge of design, construction, and operation of the building’s systems, we are equipped to recognize the cause of problems, identify contributing factors, and provide solutions.
