1	MSCA presents: Retro-Commissioning & Energy Auditing Michael J. Korcal December 9, 2008
2	"Michael J" Michael J. Korcal Associate Professor Ferris State University
3	Retro-Commissioning? Existing Building Commissioning (Retro-commissioning): Development of a BOP (Building Operation Plan) identify current building operational requirements and needs conducting tests and measurements Repair or adjust as necessary
4	Potential Problems Current equipment cannot meet the BOP. Current system layout cannot meet the BOP. Current equipment is in need of service. Current equipment can meet BOP but not as efficient as possible.
5	Building Operation Plan (BOP) Defines all aspects to optimize the function of a space / zone. Factors could include: temperature, humidity, filtration, light conditions, occupancy, ventilation, noise, pressurization, etc. Developed with the help of the building owner / occupants, codes, standards or process requirements.
6	BOP Maintenance BOP only as good as the current operation of the facility. BOP must be reviewed at least annually or when change in operation to the facility. Accurate and updated BOP is the key to the success of a retro-commissioning plan.
7	Equipment and System Evaluation êEvaluate systems to determine the ability to optimally maintain the criteria in the BOP êRequires equipment data to be collected, calculations run and a recommendation list generated.
8	Sequence of Operation If the existing equipment and systems are capable of optimally satisfying the BOP: Develop an optimized Sequence of Operation If Sequence of Operation already exists: Evaluate against the current BOP.
9	Summary Pre-Retro-commissioning Develop a Building Operation Plan Inspect and evaluate equipment Make recommendations Develop or adjust the sequence of operations Do Retro-commissioning
10	Energy Audits Evaluation of all components in a facility that effect energy consumption and efficiency Type of energy audit is based on time and money. Generates O&M and ECM recommendations
11	Types of Energy Audits Pre-audit (Utility analysis) Walk thru audit (ASHRAE level 1 or comparable) Mini audit (ASHRAE level 2) Technical Assistance Audit (ASHRAE level 3)
12	Energy Audit Areas Analyzed Building Envelope Utility Billing Computer load analysis & simulation Mechanical Systems Control Systems Lighting & Other Electrical Systems
13	Energy Audit Recommendations Operational & Maintenance (O&M) Low cost, low technical expertise measures. Arranged by simple payback Energy Conservation Measures (ECM) Capital cost, technical expertise required measures. Arranged by simple payback
14	What can the Mechanical Service Contractor Provide? Operations and Maintenance Building Operation Plan Equipment Evaluation Optimize Equipment Maintain Equipment Optimization Preventative Maintenance Equipment Recommendations Upgrades Replacements
15	What can the Mechanical Service Contractor Provide? Metering/Monitoring Validation Support Energy Conservation Methods (ECMs) Customer Education LEED Support
16	Benefits to the Building Owner: Reduced energy consumption More efficient use of energy Reduced energy costs Increased equipment lifespan Fewer down times Peace of mind Increased property values Increased rents Increased tenant satisfaction/comfort Increased productivity Decreased absenteeism
17	Benefits to the Building Owner (continued) Decreased O & M costs Take immediate advantage of new technologies or equipment upgrades Ability to apply for LEED certification. Leaders in environmental and energy efficiency Head start if the government mandates building labeling or rating State and Federal grants, loans and tax incentives
18	What Mechanical Service Contractors Need Detailed knowledge of utility billing . Factors that effect BOP or energy efficiency (building envelope, lighting, process equipment, etc. How to conduct Energy Audits Using building load/simulation software Retro-Commissioning procedures
19	What Mechanical Service Contractors Need Understanding of LEED-EB O&M requirements (if necessary). LEED AP on staff Use of MSCA Retro-commissioning and Energy Audit Manual is valuable. ASHRAE handbooks and standards. IBEAM information from government. Understanding of Energy Star portfolio manager.
