In addition to the survey phone interviews were conducted with Industry contacts in order to obtain more detailed feedback. Industry Personnel ed include Owners, Contractors, and Agents. Results What was the result of the? Owners Major benefits include reduced operations and maintenance costs. Contractors Reduced call backs for warranty and comfort issues. Agents Stress early introduction of commissioning process for project success. Results Issues that were investigated in this section include: Differences in process steps Payback Period Benefits of Results 2

3 Results Key factors that can have a direct impact on commissioning costs: When the commissioning process starts (during design, construction, or post construction) The number and complexity of systems The level of detail required during the commissioning process (does it include documenting and witnessing all equipment start-up, verification tests, spot checking the balancing report, etc.) Deliverables (design intent document, number of design reviews, commissioning plan, O&M manual review, final report, etc.) Allocation of costs (will the budget allow for increased design fee, increased contractor bid, training time for O&M personnel, the commissioning consultant s fee, etc.) Results of new buildings costs Average cost - $1 per SF Average Payback period years Retro- of existing building equipment costs Average cost - $.05 - $.43 per SF Average Payback period years Type of project (design-build, plan and spec, retrofit, etc.) Results Benefits of Buildings that factor into payback periods and return on investment include: Savings in energy cost and improved building performance Improved indoor air quality, comfort and increased productivity by building users Early detection of potential problems (the sooner problems are resolved, the less expensive they are to fix) Fewer change orders to the owner during construction Precise tune-up and operation of systems and applicable controls Better building documentation Trained building operators and maintenance staff Shortened occupancy-transition period Reduced maintenance, operation, and equipment replacement cost Results The decision to implement the commissioning or retrocommissioning processes involves several variables: Intended use of building Complexity of systems used in the building Owner s goals Availability of commissioning personnel Results 5 th and 6 th Floor Fit-Out Project: Complex systems Congested ceiling space Non-profit owner On-site operations and maintenance personnel Cardiac Elevator Addition 1,600 SF Elevator shaft and lobbies on floors 1-9 Cast-in-place concrete on composite metal decking Structural steel frame Analysis of floor system for floors 5-8 to determine pre-cast plank size availability Cost analysis Devin Learn Devin Learn Construction Construction Management Management AE AE Senior Senior Thesis Thesis 3
