Book Description
Quality assurance and optimization are essential elements of any serious technological endeavor, including efforts to improve energy efficiency. Commissioning is an important tool in this respect. 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, one-time or repeated commissioning (often called retrocommissioning) identifies the almost inevitable drift in energy performance and puts the building back on course, often surpassing the original design intent. In both contexts, commissioning is a systematic, forensic approach to improving performance, rather than a discrete technology.

Book Description
An International Approach to Sustainability was written by Steven P. Driver Ph.D. to educate anyone interested in reducing operational costs in buildings with an interest in making a difference in climate change. Through the application of energy conservation techniques, whether it's your home or workplace, this e-book can help you reduce energy consumption. This e-book was written to educate home owners, building managers, real estate developers, university and campus facility maintenance personnel, employees, and anyone else with an interest in helping our environment. This publication offers an understanding of some available technologies to mitigate energy waste. Having overcome proprietary barriers which restricted the full understanding of how to combine artificial and human intelligence with respect to building commissioning is what makes this publication unique. After completing several years of post-doctoral research to understanding differences and benefits between ongoing and retroactive commissioning, we now have a better vision of what is required to make our buildings sustainable with respect to energy consumed. This publication includes over 30 years of experience in energy management and formed the basis for a U.S trademark on Sustainable Commissioning, a concept explained in this e-book. The journey continues in researching new energy reduction technologies and piloting them confirming further effectiveness of the concept. The content in this e-book was validated through the deployment of several case studies applying the Sustainable Commissioning concept. The results from those case studies have validated an average return on investment of 62% with a 75% internal rate of return resulting in an 18 month simple pay back. The results demonstrate not only how to save operational cost, but environmental benefits averaging 1,009 metric tons of carbon emissions avoided annually for each case study.

Book Description
Many governments worldwide are setting more stringent targets for reductions in energy use in government/public buildings. Buildings constructed more than 10 years ago account for a major share of energy used by the building stock. However, the funding and “know-how” (applied knowledge) available for owner-directed energy retrofit projects has not kept pace with new requirements. With typical retrofit projects, reduction of energy use varies between 10 and 20%, while actual executed renovation projects show that energy use reduction can exceed 50%, and can cost-effectively achieve the Passive House standard or even approach net zero-energy status (EBC Annex 61 2017a, Hermelink and Müller 2010; NBI 2014; RICS 2013; Shonder and Nasseri 2015; Miller and Higgins 2015; Emmerich et al. 2011). Building energy efficiency (EE) ranks first in approaches with resource efficiency potential with a total resource benefit of approximately $700 billion until 2030. EE is by far the cheapest way to cut CO2 emissions (McKinsey 2011, IPCC 2007). However, according to an IEA study (IEA 2014a), more than 80% of savings potential in building sector remains untapped. Thus, the share of deployed EE in the building sector is lower than in the Industry, Transport, and Energy generation sectors. Estimates for the deep renovation potentials show: €600-900bn investment potential, €1000-1300bn savings potential, 70% energy-saving potential, and 90% CO2 reduction potential.

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
The U.S. Department of Energy's Rebuild America EnergySmart Schools program provides school boards, administrators, and design staff with guidance to help make informed decisions about energy and environmental issues important to school systems and communities. "The National Best Practices Manual for Building High Performance Schools" is a part of the suite of products developed to promote energy efficiency and renewable energy in schools. It was developed specifically for architects and engineers who are responsible for designing or retrofitting schools, and for the project managers who work with the design teams. The "Energy Design Guidelines for High Performance Schools," available for seven climate zones across the United States, was developed for school boards, administrators, and design staff to help make informed design decisions about energy and environmental issues important to school systems and communities. The design strategies presented here are organized into 10 chapters covering important design disciplines and goals: site design; daylighting and windows; energy-efficient building shell; lighting and electrical systems; mechanical and ventilation systems; renewable energy systems; water conservation; recycling systems and waste management; transportation; and resource-efficient building products. An additional chapter addresses commissioning and maintenance practices. Applying these guidelines will result in schools that are healthy, comfortable, energy efficient, resource efficient, water efficient, safe, secure, adaptable, and easy to operate and maintain. This manual provides details and implementation rules for individual design strategies. Though these individual strategies can improve a building's energy efficiency, only through whole-building analysis and integrated design can energy and cost concerns be balanced most effectively. A list of commissioning references and resources is included. Most chapters contain tables, footnotes, figures, and references. [The National Best Practices Manual for High Performance Schools was adapted from the Collaborative for High Performance Schools Inc.'s Best Practices Manual, Volume II. Modifications were developed by Eley Associates and the National Renewable Energy Laboratory. The adaptation was funded by the U.S. Department of Energy's Office of Building Technology, State and Community Programs. The commissioning section of this manual is a modified version of the Building Commissioning Guidelines prepared for Pacific Gas & Electric Company by Portland Energy Conservation, Inc. for the Energy Design Resources program. Certain sections of this document were excerpted and modified from Commissioning for Better Buildings in Oregon, written by PECI for the Oregon Office of Energy, and Building Commissioning: The Key to Quality Assurance, written by PECI for the U.S. Department of Energy's Rebuild America program.].
