Existing Building Commissioning Program

Existing Building Commissioning Program Opportunity Buildings throughout the U.S. use approximately 20% of all energy consumed annually. As national energy demand grows and market forces emphasize reducing energy waste building owners and property managers are looking for lowrisk solutions to reduce electricity and natural gas consumption in buildings. Siemens Building Technologies is developing a new program, Existing Building Commissioning (EBCx), to serve the expanding market need for energy savings. The EBCx Service Definition Existing Building Commissioning is an auditing service applied to existing buildings, with the intent to identify operational and infrastructure deficiencies. Through an analysis of utility costs, operational needs, and equipment performance, an EBCx audit report clearly identifies deficiencies (problems) and measures (Facility Improvement Measures-FIMs) to improve facility performance. EBCx follows a formal process and uses standard templates for testing, documenting, and planning building inefficiencies and improvement measures. The service provides value to building owners by: • reducing energy consumption • mitigating carbon emissions thereby reducing overall carbon footprint • contributing to LEED certification (up to 6 points) EBCx is a one-time consulting service where an Energy Engineer and Service Technician partner to audit a facility and develop a plan to improve efficiency.

Energy Saving Potential Research by Lawrence Berkeley National Laboratories and other universities and not-for-profit organizations state Existing Building Commissioning projects provide savings of 10% to 20% with an average simple payback slightly over 1 year. These projects are low-risk investment opportunities with an average cash-on-cash return on investment greater than 90 percent. Cost savings for EBCx projects are expected to last 3 to 5 years. They are among the most cost effective energy program available as demonstrated by the following table.

The intent of the EBCx program is to serve the commissioning need in the commercial buildings market. With minor modifications, this program can also serve institutional, K-12 schools, universities and industrial markets (revenue from commissioning work nationwide is estimated by Pike Research to be $4B over the next 5-10 years).

The EBCx Service Siemens Building Technologies will deliver the following items as part of the EBCx Service: • A facility benchmark analysis tool comparing facilities against industry standards for comparable buildings in similar climates. This can be either Energy Star or the EMC Utility Data Analysis (UDA) Report (if pursuing LEED, Energy Star Portfolio Manager is required). • Internal and external sales tools including PowerPoint presentations, proposal templates with standardized language, contract language and a list of required EBCx tools. • An Existing Building Commissioning sample report showing mechanical, electrical, and automation inventory, recently performed facility improvement measures, and operating conditions of equipment. • A list of proposed operational improvements with associated costs and savings projections. • A list of proposed capital improvements with associated costs and savings projections (LEED EAc2.2 requires a list of capital improvements evaluated but deemed not feasible if pursuing Option B). • Cash flow analysis of potential savings. • EBCx Intranet website with tools, references and pertinent links related to commissioning, etc. • System manuals. • Comprehensive EBCx training to area sales and engineering personnel. • Comprehensive training to managers and operators of the building.

Four Phases There are four phases to the EBCx service: Planning PhaseSelect the project, assemble the commissioning team, gather building data, create the EBCx plan, and hold a kickoff meeting with the customer. This phase is import to ensure the scope and deliverable are clearly defined. Investigation PhaseReview facility documentation, profile and analyze BAS trend files, perform functional tests of equipment/systems included in the scope, perform simple repairs, develop list of findings, prioritize and select operational improvements. This phase take us from defining the scope to defining the improvement measures. Implementation PhaseDevelop and implement agreed upon measures and verify results. This can include BAS FIMs, mechanical FIMS, and electrical FIMs. Project Hand-OffDevelop the final report, develop and systems manual, provide customer training, and close-out the program.
