Campus buildings typically represent 80% of the energy use for the entire college or university and are therefore prime targets for energy reduction / carbon reduction initiatives. Retro-commissioning is the process of optimizing building system performance to design intent, with energy reduction a primary result. This process is well-documented in producing energy reduction of 15% - 25%, 10% or more without any capital equipment costs (Phase I retro-commissioning).
Before you take building performance advice from equipment or software vendors, let us show you a better way to control costs and retain energy savings. EH&E combines extensive building science, engineering, building system performance and sustainability experience, and offers a truly independent assessment (and strategic view) of your campus building stock and carbon reduction goals.
EH&E can perform a very inexpensive assessment of your entire building stock using available building information and energy data to identify those buildings that represent the greatest energy reduction potential via retro-commissioning. A walk-through will be conducted of these potential targets to confirm the assessment, and a general estimate given for potential savings in both energy and carbon reduction.
EH&E’s retro-commission process proceeds in three phases:
Phase I – Develop a building system performance profile
Defines the building’s optimal operating strategy and identifies the system(s) to be optimized, documents all associated equipment, and reviews the system control sequences. System performance data is collected and analyzed to identify opportunities. This phase typically identifies some low or no – cost actions to improve performance, as well as issues that require some engineering investigation to further refine.
Phase II - Perform engineering investigation and make recommendations
A more detailed engineering investigation with recommendations for improvement for more complex deficiencies. EH&E engineers work with the facility manager and operations staff to select specific items to undergo further investigation and engineering.
Phase III - Correct deficiencies, analyze results, and recommend capital improvements
Prioritization and correction of those equipment and system deficiencies selected from Phase II. Can be prioritized to target individual zones, systems, or the entire building based on the projected ROI of the proposed improvements.
EH&E’s engineers can work closely with the facilities staff throughout several retro-commissioning projects with the goal of training key staff to perform the service without site support from EH&E. EH&E encourages self-reliance as an economical way to optimize lower energy use buildings and to encourage commissioning on a regular basis to maintain optimized performance.
