Existing Building Commissioning
If you’re looking for ways to lower your utility costs, operation overhead, and make your building more efficient, GMC Commissioning’s Existing Building Commissioning (EBCx) is the answer. EBCx is for buildings that have high energy use, unexplained increases in energy consumption, abnormally high failure rates of systems and equipment, and persistent issues maintaining constant conditions.
A Holistic Approach to Optimization
Our EBCx process isn't just about fixing isolated problems; it's about taking a holistic approach to optimization. We delve deep into every aspect of your building's operations, leaving no stone unturned in our quest for efficiency. From fine-tuning existing systems to implementing cutting-edge technologies, we leave no opportunity for improvement untapped.
Despite initial commissioning efforts, even well-maintained buildings experience a decline in efficiency over time. This is where re-commissioning, retro-commissioning, ongoing commissioning, and Monitoring Based Commissioning step in as crucial measures to maintain and reduce energy consumption.
A Proactive Approach to Efficiency
At GMC Commissioning, we understand the importance of a proactive approach to efficiency. Our EBCx process involves thorough planning, assessment, investigation, analysis, and optimization to ensure that your building operates at optimal levels. By identifying inefficiencies and areas for improvement, we pave the way for significant cost savings and environmental benefits.
Advanced Analytics
GMC Commissioning implements a custom, in-house developed Skyspark MBCx program including tagging, mapping, developing fault detection algorithms, rules, and dashboards to assist in the existing building commission process. SkySpark is a software analytics platform that automatically analyzes system-level building data and provides building insights.
GMC Commissioning custom developed energy applications give building operators insight into where and why energy is being used. Dashboards show real time building energy demand compared to baselines, historical data, and statuses of lights and HVAC systems within the same timeframe. e help clients realize the benefits of SkySpark with set-up and implementation assistance including.
Retro-Commissioning
Retro-commissioning existing buildings offers the most benefit in terms of opportunities for cost savings and improving energy efficiency in commercial and industrial building. Retro commissioning is the same systematic process as new construction commissioning, but applied to existing buildings that have never been commissioned to ensure that their systems can be operated and maintained according to the owner’s needs.
Energy Audits
On average, commercial buildings waste 30% of their energy, according to the EPA. Commercial energy audits and the energy saving recommendations they produce help businesses reduce that waste while lowering operating expenses, reducing their carbon footprint, and allowing them to qualify for energy rewards programs to secure better financing.
Re-Commissioning
As soon as a building is operational, systems begin to drift and wear. Re-Commissioning provides a reset as if the building systems were being installed new. For buildings that have already been commissioned or retro-commissioned, it is recommended that the practices of recommissioning or ongoing commissioning be applied.
There are different kinds of commercial energy audits available with varying levels of detail, depending on your goals.
ASHRAE LEVEL 1 AUDIT – “WALK-THROUGH ANALYSIS”
An ASHRAE Level 1 audit is the most basic level of audit, designed to give businesses a starting point for making changes or further in-depth auditing.
This audit can include steps such as:
Interviewing key operations personnel
Reviewing facility utility bills
Walking through the site
The goal of an ASHRAE Level 1 audit is to identify glaring areas of energy inefficiency. All gathered data is then compiled into a report detailing no- or low-cost changes that can be made to the building, as well as other potential capital improvements earmarked for further study.
ASHRAE LEVEL 2 AUDIT – ENERGY SURVEY & ANALYSIS
A Level 2 audit begins with everything in a Level 1 audit but takes the data collection and final reporting a step farther.
The building’s energy consumption is broken down by end-use, helping to identify the areas with the greatest opportunities for improved efficiency. Utility rates are analyzed to see if there are opportunities to secure a lower rate.
Important building personnel also are interviewed to provide insights into characteristics of the building’s operations, areas of potential problems, and to define the financial and non-financial goals for the audit.
A Level 2 audit provides enough data to justify the implementation of a project without the need for additional data collection and analysis.
ASHRAE LEVEL 3 AUDIT – DETAILED ANALYSIS OF INTENSIVE CAPITAL IMPROVEMENTS
A Level 3 audit builds on the findings and recommendations of a Level 2 audit by offering a more in-depth engineering analysis of potential changes.
Detailed gathering of data in the field is conducted, and that data is analyzed more intensely for areas of improvement and potential costs.
Existing data on utilities is supplemented by sub-metering of the energy consumption of key systems such as HVAC, as well as monitoring of those systems’ individual characteristics.
Site Assessments and Due Diligence
We use actionable intelligence to optimize and maintain your building’s performance. Avoid down time and costly repairs with upfront data provided by a quality MEP Systems Assessment. MEP systems are some of the most critical components of your building’s infrastructure. Whether you’re evaluating a property for a potential acquisition, or performing routine capital needs planning,
