3 Presentation Description This presentation describes the importance of building commissioning in an effective comprehensive energy plan. It also describes the options for commissioning that are currently in the market and makes the case that no matter what solution is chosen, it must combine a mix of people, process and technology in order to be truly successful.

4 Learning Objectives At the end of this session, participants will be able to: 1. Describe a comprehensive energy strategy 2. Articulate how commissioning fits into a good energy strategy 3. Understand the current offerings around commissioning 4. Understand the importance of people, process and technology coming together to form a commissioning program

5 It s a Complex Industry

6 Drivers and Desired Outcomes The two must be aligned Drivers Outcomes (Examples) People 20% better test performance in schools 2-16% productivity increase in offices Earlier patient discharge in hospitals Financial Reduced energy and operating costs Increased value of building Improved revenue per square foot in retail Sustainability Enhanced sustainability Conservation of natural resources Better stewardship

7 Critical Challenges in Achieving Corporate Goals Resource Constraints Economic conditions forced reductions in headcount Skill set of staff, retiring workforce Capital budget is reduced Unable to deliver needed results Infrastructure Increasing deferred maintenance expedites asset degradation Aging equipment increases operating costs Lack Infrastructure and strategy to support increased data Energy & Sustainability New mandates for energy reduction, CO 2, LEED, Energy Star Tracking/reporting are unfunded Strategic plans are often under-funded and results mixed Increased stakeholder needs

8 Delicate Balance of Priorities Comfort, Safety and Efficiency Indoor Environments Efficiencies & Sustainability High performing, efficient and sustainable buildings Owners most important building performance value categories* Top 3 by a large majority: Systems Environments (indoor) Energy Financial Sustainability Reliability Lifecycle Compliance * Internal research

9 Comprehensive Energy Strategy Deliver outcomes aligned with goals Understand Goals and Needs Plan: Understand goals & needs across full range of stakeholders Evaluate: Understand current situation, assemble best offering mix and establish KPI s, aligned to business goals Deliver On-Going Value Implement: Turnkey design and delivery of improvement actions Service: Ensure customer savings persist over time Measure: Provide quantification of KPI s and frequent touch points Repeat the process, making adjustments to align with new customer priorities and additional performance opportunities Repeat the process Efficiency Supply Sustainability Entry point depends on your unique situation Process is flexible and scalable Maximum results with all phases & disciplines

10 Answering Customer Concerns The Value of a Comprehensive Energy Strategy How can we develop a master plan for energy and sustainability? How can we mitigate risk from fluctuating energy prices? How can we gain transparency into our current energy use and spending? How do we know which corrective actions will have the greatest impact on our business? How can we conserve energy and run a more sustainable business? How can we maintain transparency and quickly identify new opportunities? How can we ensure that the savings we generate aren't lost over time?

11 Building Commissioning An Essential Part of an Effective Comprehensive Energy Strategy Strategy & Planning Understand goals & needs of the Commissioning Plan Obtain baselines Develop team of critical stakeholders Evaluation & Assessment Conduct assessment and investigation phases of an Existing Building Commissioning project Determine CCAM Measurement & Reporting Apply technology to better understand building Identify trends and opportunities for improvement Develop ongoing reports based on relevant KPIs Program Implementation Implement chosen FIMS (ECMs) Make any low/no-cost improvements that weren t made throughout Evaluation & Assessment phases Ongoing Services Through Monitoring Based Commissioning, identify new opportunities

12 Commissioning has Evolved Origination Creation and Definition ASHRAE and BPA define and test Federal Government issues first executive order Early adopters implement and provide first case studies Accepted Market accepts Cx as standard practice Utilities develop programs Retro Commissioning created for existing buildings Streamlines processes and definition, resulting in proven energy and operational savings Technology leveraged to create tools for better analysis of data First government agencies pass new Cx code Certification programs started to standardize professional training Comprehensive Focus on end to end delivery Market demands comprehensive solution including Retro and Persistent commissioning together The focus is implementation for recommendations from Retro and Persistent Cx with focus on productivity of customers people and processes, with technology as the enabler As in the past, actionable information is provided to make better decisions, and now scope is expanded to: Data analytics and optimization strategies Remote monitoring and maintenance of systems Proactive service Energy Management Sustainability

13 Nomenclature and Key Definitions Cx Existing Building Cx (EBCx) Retro Cx Re Cx Monitoring Based Cx (MBCx) Continuous Cx * Fault Detection and Diagnostics (FDD) Automated Fault Detection EBCx Existing Building Commissioning Optimizes building systems performance according to its current facility requirements Assessment of supply-side and demand-side Supported by ongoing services and metrics from MBCx and FDD MBCx Monitoring Based Commissioning Provides a persistence of savings through technologybased analysis of building operations data Relies on baseline from an EBCx project and quickly remedies deviations FDD Fault Detection & Diagnostics Detects and diagnoses system faults Supports EBCx and MBCx Near real-time data collection of large amounts of building data Identification of operational exceptions and issues * Continuous Commissioning is a registered trademark of Texas A&M

14 3 Critical Parts to a Commissioning Program Strategy & Planning EBCx: An EBCx program will involve work in the Plan, Evaluate and Implement phases and will rely on people, processes and technologies in order to drive home results. MBCx: MBCx programs will involve ongoing service and data driven measurement and reporting. Like EBCx, a combination of people, process and technology are necessary for a successful MBCx program. FDD: FDD is an important tool that can be leverage to create quick and cost effective results during the Evaluate, Service and Measure phases. FDD relies heavily on technology in order to be successful.

15 Comprehensive Commissioning Programs Value through Integration Building Operational Costs Implement EBCx Implement MBCx Without Continuous Improvement Total Value Added Implement FIMs ADDED VALUE Building operating costs increase over time The Commissioning Advantage from Siemens quickly and effectively lowers operational costs Without holistic commitment, costs rise to original levels Savings persists with Monitoring Based Commissioning (MBCx) Savings increase as additional opportunities are identified and implemented LEGEND One-time Project Fees On-going Service Fees Cost of commissioning is always lower than the value added to the customer s operational goals 1 st year 2 nd year Years of operation

16 Current Options in the Marketplace In House Description: Using in-house resources and readily available guidelines, data collection and analysis tools, building managers/operations team self-commission buildings Pros: 1. Inexpensive (perception vs. reality) 2. Best knowledge of building stock? 3. Can implement quickly Cons: 1. Groupthink 2. Proceeds slower than normal 3. Resource constraints may lead to short-circuiting process

17 Current Options in the Marketplace Partial Commissioning Providers Description: Companies with experience in commissioning processes who may excel at planning and evaluation but not have the resources or experience to implement/validate improvements Pros: 1. Less expensive than full service solution 2. Many companies provide this service (RFP?) Cons: 1. Not turn-key solution 2. Owners may waste time looking/hiring project implementers

18 Current Options in the Marketplace Decentralized Commissioning Providers Description: Customers hire experts to commission each building system: mechanical service providers, electrical service providers, energy engineers, etc. Pros: 1. Individual vendors bring dedicated knowledge and expertise 2. Less expensive (?) Cons: 1. May not get a holistic view of the building s performance-improvements to each system occurs independently of other systems performance 2. Optimal performance never achieved

19 Current Options in the Marketplace Full Service Commissioning Providers Description: Companies with expertise in commissioning processes with adequate resources and tools provide turn-key commissioning services with post-project monitoring to ensure persistence of savings Pros: 1. Maximum value 2. Lowest lifecycle cost Cons: 1. Higher Upfront Costs

20 Current Options in the Marketplace IT Consultants Description: Examine buildings IT network and disparate data sources. Have begun adding analysts to examine energy and operations performance Pros: 1. Help recommend and implement an IT software/network architecture 2. Provide trending data, analyze it in near real time 3. Can often provide detailed reports with recommended actions in a matter of days Cons: 1. Lack the people who understand mechanical and automation systems and data sufficiently 2. Lack of capability to implement recommended fixes

21 Current Options in the Marketplace Software Companies Description: Examine buildings IT network and disparate data sources. Have begun adding analysts to examine energy and operations performance Pros: 1. Provide advanced technology for Analytics 2. Analysis of data at your fingertips 3. Best Practices for Fault Detection and analytics Cons: 1. Typically rely on 3 rd parties for integration and implementation of their software 2. Lack people to interpret faults from the software 3. Lack of capability to implement recommended fixes

22 People, Process & Technology A Necessary Trio People: Trained and available human resources Plan, evaluate, implement and service any energy strategy Multiple shareholders including internal employees and external partners Process: Involves a multi-phased, recursive process Whole is greater than the sum of its parts. People Technology: Critical support role Identify specific actions; leads to savings Process Technology
