Book Description
Commissioning is coming of age. Savvy building owners have adopted commissioning as an effective way to improve the facility acquisition process. Green building initiatives have embraced commissioning as a way of assuring quality in the delivery of high-performance buildings. This long-established quality control process for building mechanical systems is emerging as a broader construction management tool improving nearly all aspects of a project. What exactly is this thing called commissioning? Principles of Building Commissioning answers this fundamental question with the first all-inclusive, practical guide to the application of the principles of commissioning. The book clarifies the underlying philosophy of commissioning: the why, what, when, and who of this process. Shaped by the ASHRAE Guideline 0 view of the world of commissioning, Building Commissioning: Maps out the territory of commissioning Outlines its defining characteristics Explains its flow of processes Demystifies its documentation Making the fundamentals of commissioning accessible to all parties—building owners and operators, architects and engineers, users and suppliers—who may be called upon to join the commissioning team for a particular project, Building Commissioning serves as the professional's road map to the commissioning process, from the predesign phase through occupancy.

Book Description
This book discusses building commissioning, which is the process of certifying that a new facility meets the required specifications. As buildings have become more complex, the traditional methods for building start-up and final acceptance have been proven inadequate, and building commissioning has been developed, which often necessitates the use of outside consultants to monitor the process. One-half of the guide details the roles of the consultant, contractor, test engineer, commissioning agent, and owner. It describes the process, the needed equipment testing, systems functional performance testing, scheduling, documentation, training, costs, and the process of hiring a commissioning agent. Chapters include an overview of commissioning and discussions of: approaches to commissioning, design requirements, contract documents requirements, the steps of the commissioning process, selecting the commissioning agent, and the costs of commissioning. A case study of commissioning a science building is provided. The other half of the guide consists of a description of terms and 15 different guide specifications in the form of detailed documentation and testing checklists, divided to indicate specific tasks and tests (e.g., general, mechanical, electrical facility startup/commissioning; commissioning--general requirements; HVAC systems, supply air systems, exhaust air systems, environmental control systems, etc.) (JLS)

Book Description
The aim of commissioning new buildings is to ensure that they deliver, if not exceed, the performance and energy savings promised by their design. When applied to existing buildings, commissioning identifies the almost inevitable 'drift' from where things should be and puts the building back on course. In both contexts, commissioning is a systematic, forensic approach to quality assurance, rather than a technology per se. Although commissioning has earned increased recognition in recent years - even a toehold in Wikipedia - it remains an enigmatic practice whose visibility severely lags its potential. Over the past decade, Lawrence Berkeley National Laboratory has built the world's largest compilation and meta-analysis of commissioning experience in commercial buildings. Since our last report (Mills et al. 2004) the database has grown from 224 to 643 buildings (all located in the United States, and spanning 26 states), from 30 to 100 million square feet of floorspace, and from $17 million to $43 million in commissioning expenditures. The recorded cases of new-construction commissioning took place in buildings representing $2.2 billion in total construction costs (up from 1.5 billion). The work of many more commissioning providers (18 versus 37) is represented in this study, as is more evidence of energy and peak-power savings as well as cost-effectiveness. We now translate these impacts into avoided greenhouse gases and provide new indicators of cost-effectiveness. We also draw attention to the specific challenges and opportunities for high-tech facilities such as labs, cleanrooms, data centers, and healthcare facilities. The results are compelling. We developed an array of benchmarks for characterizing project performance and cost-effectiveness. The median normalized cost to deliver commissioning was $0.30/ft2 for existing buildings and $1.16/ft2 for new construction (or 0.4% of the overall construction cost). The commissioning projects for which data are available revealed over 10,000 energy-related problems, resulting in 16% median whole-building energy savings in existing buildings and 13% in new construction, with payback time of 1.1 years and 4.2 years, respectively. In terms of other cost-benefit indicators, median benefit-cost ratios of 4.5 and 1.1, and cash-on-cash returns of 91% and 23% were attained for existing and new buildings, respectively. High-tech buildings were particularly cost-effective, and saved higher amounts of energy due to their energy-intensiveness. Projects with a comprehensive approach to commissioning attained nearly twice the overall median level of savings and five-times the savings of the least-thorough projects. It is noteworthy that virtually all existing building projects were cost-effective by each metric (0.4 years for the upper quartile and 2.4 years for the lower quartile), as were the majority of new-construction projects (1.5 years and 10.8 years, respectively). We also found high cost-effectiveness for each specific measure for which we have data. Contrary to a common perception, cost-effectiveness is often achieved even in smaller buildings. Thanks to energy savings valued more than the cost of the commissioning process, associated reductions in greenhouse gas emissions come at 'negative' cost. In fact, the median cost of conserved carbon is negative - -$110 per tonne for existing buildings and -$25/tonne for new construction - as compared with market prices for carbon trading and offsets in the +$10 to +$30/tonne range. Further enhancing the value of commissioning, its non-energy benefits surpass those of most other energy-management practices. Significant first-cost savings (e.g., through right-sizing of heating and cooling equipment) routinely offset at least a portion of commissioning costs - fully in some cases. When accounting for these benefits, the net median commissioning project cost was reduced by 49% on average, while in many cases they exceeded the direct value of the energy savings. Commissioning also improves worker comfort, mitigates indoor air quality problems, increases the competence of in-house staff, plus a host of other non-energy benefits. These findings demonstrate that commissioning is arguably the single-most cost-effective strategy for reducing energy, costs, and greenhouse gas emissions in buildings today. Energy savings tend to persist well over at least a 3- to 5-year timeframe, but data over longer time horizons are not available. It is thus important to 'Trust but Verify, ' and indeed the field is moving towards a monitoring-based paradigm in which instrumentation is used not only to confirm savings, but to identify opportunities that would otherwise go undetected. On balance, we view the findings here as conservative, in the sense that they underestimate the actual performance of projects when all costs and benefits are considered. They underestimate the technical potential for a scenario in which best practices are applied.

Book Description
Prepared in cooperation with Disney Development Company, this book deals exclusively with aspects of the design, construction or operation of buildings for which even relatively minor errors can have devastating results when the building is located in a hot, humid climate. Disney's consistent adherence to the principles outlined in this manual has dramatically reduced problems in its new construction. The information presented combines the experience of CH2M Hill, the largest environmental engineering firm in the U.S., and Disney, one of the premier facility planning and management firms in the world. Key issues covered include indoor air quality problem factors; hot humid climate considerations; new building failure; and a model for future success. Specifically addressed are schematic design, design development, final design, construction, and post-construction startup and system commissioning. The concepts and approaches presented are those which have proven successful in designing and operating problem-free indoor building environments in hot and humid locations.
