To prevent the unintended utilization of extension cords and to eliminate daisy-chains of “power strips”, the 2017 version of the National Electrical Code (NEC) now provides guidelines for locations and quantities of receptacles provided in meeting rooms. Historically, the NEC has not dictated receptacle layouts for individual space types in non-residential construction.
Per the NEC, meeting rooms are typically designed or intended for the gathering of seated occupants for such purposes as conferences, deliberations, or similar purposes, where portable electronic equipment is likely to be used. The infographic below helps explain the receptacle and floor box layout process, but Article 210-71 in the 2017 NEC outlines the actual requirements.

International WELL Building Institute (IWBI), and is third-party certified through IWBI’s collaboration with Green Business Certification Inc. (GBCI). more
A building becomes intelligent when its HVAC, lighting, power, low voltage, and other systems speak the same language, share meaningful information, and work together to enhance the building’s performance, add functionality and achieve performance, wellness, and engagement goals. This gives building owners the ability to install apps, such as Comfy, which provides the occupant control over zone lighting and temperature from their phones. Apps like Rifiniti also generate statistics about the usage of the rooms in a building. more
Since the first water-tube boilers made over one hundred thirty years ago, central energy plants have provided a consolidated energy source for multiple building complexes. Central utility plants now include boilers, chillers, thermal storage, cogeneration equipment, electrical gear and monitoring, and energy management systems. The primary benefits of central utility plants, compared to smaller local systems, are reduced operating costs, better maintainability, less downtime, and easier servicing. The major disadvantage is first cost. more
The American health care system remains the worldwide standard for quality care, physicians produced, and research. One of the obvious reasons for this reputation is the commitment to excellence evidenced in the facilities cooperated by medical schools.

The medical school of tomorrow uses the latest in technology, energy conservation, and facility design to attract and educate both physicians and scientists. more
Technological advancements in the building design and construction industry are allowing the performance envelope to be pushed from all directions. Reducing energy usage, improving occupant comfort, optimizing lighting levels, and integrating systems to simplify operation and maintenance practices are all examples of issues that require close scrutiny and expertise when designing high performance buildings. To achieve success with such projects, high performance buildings require a more collaborative approach to design and construction. In order to produce and sustain the performance levels of these types of facilities, owners are actively involved during the design process and have upgraded their approach to operations and maintenance. more
Communications, entertainment, productivity and resource management are all becoming increasingly mobile. As smartphones and mobile devices proliferate, people are expecting the same level of mobility at the office and in public spaces. Planning for successful and comprehensive wireless voice and data applications requires an understanding of networks, cabling infrastructure, building design and radio frequency (RF) signal behavior. more
The current approach in building design focuses almost solely on increasing energy efficiency by improving system-oriented controls and behavior. However, occupant behavior also affects energy efficiency. To provide a more realistic modeling result, occupant behavior needs to be included in energy modeling. more
“Entities should not be multiplied unnecessarily.”
– Franciscan friar William of Ockham
Among competing hypotheses, the one with the fewest assumptions should be selected. There are many interpretations of Occam’s Razor, a line of reasoning attributed to English philosopher William of Ockham, but put most plainly: the simplest explanation is usually right. Scientists, detectives, and doctors all use the razor to trim away improbable explanations and arrive at the truth. more
A master plan is a critical tool for any building owner. Most facilities management, design and construction professionals recognize the value of a master plan for a building or campus. A master plan focuses attention on the owner’s ultimate goals so that every facilities decision contributes to these goals. Some master plans, though, focus almost exclusively on architectural issues and do not adequately address engineering and infrastructure features. An engineering master plan, whether separate or as part of an architectural master plan, can allow building system and utility infrastructure decisions to be made within a framework that furthers the owner’s goals in a cost-effective and efficient manner. more
Institutional Owners are groups who build, own, renovate, and maintain multiple buildings on a regular basis. These Owners are more likely to be interested in longer payback on initial building capital costs to achieve straightforward maintenance and lower energy consumption. They are sophisticated and know how they want their buildings and consultants to perform. These types of Owners may be in the business of higher education, aviation, healthcare, research, corrections, or corporate activities, among others. They may be public or private. They all have common needs that are different, and in most cases, more complex than those of other Owners. more
As a result of the political and economic events of recent years, governmental revenues available for correctional facilities’ construction and operation have steadily declined. To continue providing value to our clients, correctional facilities designers must adapt to the constraints imposed by reduced funding.

Agent-based modeling and multi-agent modeling are relatively new methods that have been successful in answering many biological, social and behavioral questions such as analysis of the spread of epidemics, workforce management, and modeling consumer behavior in recent years. They share overlapping roots with gaming theory and its concepts, and adopting this type of modeling into engineering systems decision-making can create solutions to our daily problems in ways that were not possible before. more
Sound influences our daily lives regardless of its intent. Advancements in the field of acoustics have led to a more comprehensive understanding of the relevance of this science to our world. Effective, collaborative efforts, along with thoughtful design strategies, can result in an environment that enhances our perception, and ultimately our performance. more
An electrical hazard analysis identifies dangers that are present in an electrical system. This starts at the building’s electrical service and continues through the electrical distribution system to the building loads, including panelboards, motors, safety switches, etc. This analysis should identify electrocution (shock) hazards, arc flash (burn) hazards and arc blast (pressure & shrapnel) hazards. more
The pursuit of the Living Building Challenge pushes projects to be not just ‘less harmful’ to the environment, but to be at a minimum neutral and at its utmost, a ‘restorative’ impact to the environment.
The Living Building Challenge currently has over 200 projects registered in 14 countries, including the United States, Canada, China, India, Mexico, Haiti, Lebanon, France, Romania, Australia, and New Zealand, in various stages of design, construction, and occupancy.
Similar to LEED, it is a holistic approach to the building design but pushes the boundaries by achieving net positive energy, net positive water, and paying careful consideration to the materials used. Site, equity, beauty, health, and process are also critical components incorporated into the design. more

Have you ever wondered what the most frequent citations are during Joint Commission surveys? Speculate no more! The Joint Commission has teamed up with The American Society for Healthcare Engineering (ASHE) to identify the top eight physical environmental standards that are most frequently cited during Joint Commission surveys. Physical Environmental standards include, but are not limited to, fire safety features, egress concerns, and mechanical and electrical system design and operation issues. Citations are made during on-site surveys conducted by The Joint Commission every three years as a part of the process that allows hospitals to maintain their accreditation. more
Two years ago, I was invited to visit the Atlanta corporate campus of Assurant, Inc. to discuss their Energy Star score – it was too low and they wanted to do something about it. The twelve story office building was burdened by a chiller plant that was all original construction. Chillers, pumps, and cooling towers were well-maintained, but after more than 27 years of service, they were showing their age and not performing at the level they once did. This initial meeting unofficially began design efforts that have resulted in the recent completion of a $5.7 million upgrade to the HVAC and Electrical systems, a construction project that already has proven itself with lower electrical bills that bring a smile to Tony Ring, Manager of Maintenance Operations for Assurant. more
In this 21st century, it is truly amazing how quickly we can gather so much data with just a few mouse clicks! Our company database stores information for our 10,000+ projects, 4,500+ opportunity pursuits, 6,000+ companies, provides resume information for our 160+ employees, and even tells me that I have logged 51,665 hours to 344 Newcomb & Boyd projects (insert engineers and numbers jokes here). more
The National Fire Protection Association (NFPA) standard 96 clearly states the requirements for Type I grease hoods over commercial cooking equipment, but what are the requirements for hoods over domestic cooking equipment and how should we approach the installation of domestic cooking equipment in a commercial facility? more
The second session I attended at the 2015 American Alliance of Museums was Spatially Literate Digital Experiences with Nathan Moody and Alan Maskin. The presentation opened with the picture of a musical swing set in Montreal, seen above, which shows consideration of spatially literate designs. In this exhibit the designers found an underused area and, understanding the desire for community involvement, created an interactive exhibit that was so popular it is now a permanent installation! more
Today, the unfortunate news of a shooting at our nation’s schools is far too common. As educational campuses implement security measures and create plans of action in the event of an attack, Corporate America is also considering their course of action to mitigate the threat of, and prepare for, an active shooter. more

Newcomb & Boyd attended the Lean Construction Institute (LCI) – Georgia Community of Practice Integrated Project Delivery Panel on July 30 where we learned about some of the top integrated project delivery (IPD) methods from leaders in the A/E/C industry. more
In my earlier columns, I tried to explain the concept of uncertainty analysis and also draw the attention of the industry to the advantages of performing probabilistic energy modeling. One of the most valuable complementary tools to uncertainty analysis is sensitivity analysis. Terje Aven in his book, Foundation of Risk Analysis,1 gives the following definition for sensitivity analysis: “A sensitivity analysis is a study of how sensitive the risk is with respect to changes in input parameter of risk model.” more
Successful museum design encompasses a number of challenges requiring knowledge and expertise in acoustical soundscapes, audio-visual technology, lighting solutions, and security measures. Equally as important is commissioning systems to ensure mechanical, electrical, and plumbing systems function as required the sensitive museum environment. more
Health-care design evolves constantly, reflecting improvements and advancements in surgical techniques, equipment (such as MRIs and robotic surgical equipment), clinical practices, hospital design trends, energy efficiency, sustainable design, and other factors. Ventilation for health-care facilities must change to be aligned with the changing needs of health-care facilities design, patients, surgeons, clinical staff, and visitors. more
Building an energy-efficient building often begins with an energy (cost) comparison between a design building and an imaginary baseline building as defined in ASHRAE/IES Standard 90.1, Appendix G. Even though this method has contributed to higher performance of buildings and systems, I believe we can do better than that. more
When one thinks of critical infrastructures, some come quickly to mind: the water system, the power grid, the Internet, dams, bridges, roads, air and rail transportation to name a few. Commercial buildings may not occur to the average individual as critical infrastructure, but they are considered as such by the Department of Homeland Security (DHS) and ASIS International. If we think about the impact of the 9/11 attack on the Twin Towers, we understand why. The attack on the Twin Towers cost nearly 2,600 people their lives, and launched the United States into a long term war on terror that has increased the national debt approximately 1.5 trillion dollars.1 more
A truly effective audio-visual presentation system must be planned, designed, and implemented as a fully integrated set of subsystems. A well-designed system should make any presentation easier and more effective, accommodating a wide variety of presentation types and presenter styles. Proper planning of a presentation system requires consideration of acoustics, lighting, potential audiences, and potential media formats ranging from speech reinforcement to multimedia presentations. A well-designed system should be as transparent as possible allowing the focus to be on the message. more
In my November column, I discussed the necessity of performing a probabilistic energy modeling process instead of a deterministic one for an ASHRAE/IES Standard 90.1, Appendix G, design building. To be able to run a probabilistic energy model, the first step is to develop a tolerance margin library for all the construction material that would be used in constructing a building and for its associated equipment. more
Uncertainty analysis is the process of changing simulation model input parameters in a small margin of possible occurrences and observing how simulation output can be affected (output probability distribution). That is the basic difference between a deterministic simulation and a probabilistic (uncertain) simulation. Uncertainty analysis is a strong tool for modelers and those who use modeling results to make well-informed decisions. more
Universities and colleges are experiencing growth and pressure on existing aging facilities. This occurs at a time when funding from both government sources and endowments is decreasing. Students also have higher expectations for the facilities, resources, and amenities; the perceived quality of residence halls, dining facilities, student unions and recreational facilities can be important factors in a student’s school choice. more
Mission critical facilities support computing resources that have no tolerance for downtime caused by system failures. The unique nature of these facilities requires close coordination between the building design team and information technology equipment providers so that resources can be put in place to provide cooling, power, and connectivity that best suit the equipment while allowing for planned equipment maintenance as well as equipment failures, while maintaining operation. more
Most HVAC design engineers use an array of sophisticated software calculation and modeling tools for load calculations and energy analysis. These tools offer almost total flexibility for the engineer to define physical arrangement, thermal parameters, operating schedules, internal loads and zoning. To achieve that flexibility, the input parameters are extensive and time consuming. more
Laboratory facilities are highly complex and specialized. Academic teaching laboratories, corporate research laboratories, testing facilities, public health laboratories, pharmaceutical facilities, biomedical research laboratories, and biocontainment research facilities all require that comfort, safety, flexibility, future growth, standards, regulations and energy usage be balanced. Successful laboratory design depends on managing multiple criteria in increasingly sophisticated facilities. more
Architects have long embraced BIM, and software developers are moving to add mechanical, electrical and plumbing to the models. ASHRAE Technical Committee 4.1, Load Calculation Data and Procedures, prepared a seminar for the 2010 ASHRAE Annual Conference to examine the state-of-the-art for using building information modeling (BIM) for load calculations, including methods of extracting data from the BIM model for import into traditional stand-alone calculation programs and use of built-in “native” BIM load calculation software. This article addresses native BIM load calculations only, although lessons learned regarding interoperability and data definition apply to both approaches. more
ANSI/ASHRAE/ASHE Standard 170-2008, Ventilation of Health Care Facilities, can be adopted by authorities for health care facility construction and private national organizations such as the Facilities Guidelines Institute (FGI). In 2010, FGI incorporated Standard 170- 2008 as Part Six of its Guidelines for Design and Construction of Health Care Facilities.1 This includes all addenda, present and future, issued by ASHRAE. The Joint Commission, federal agencies and authorities in 42 states use the Guidelines either as a code or a reference standard when reviewing, approving, and financing projects or when surveying, licensing, certifying or accrediting newly constructed facilities, according to FGI. more
Specialty systems include many of the low-voltage systems that comprise the tools necessary for information professionals to produce work. Many applications such as e-mail, messaging, telephony, security systems and building environmental controls depend on the LAN and WAN and require a robust combination of physical hardware and logical configuration to operate correctly. As we learned by watching the heating, ventilating and air conditioning (HVAC) industry, benefits can be realized by more closely involving the design team, the contractor and the owner during the implementation phase to ensure that systems operate as intended and can prove themselves fully during a performance evaluation. more
Vivariums present many unique challenges to design and construction professionals. Due to the stringent environmental and construction requirements, designers and builders have their hands full ensuring the facility meets the numerous standards regulating these spaces. more
HVAC systems in a typical laboratory facility can use five to 10 times as much energy as the systems in a typical office building.1 This higher energy use is due to many factors including 100% outside air systems; 24-hour-a-day operation; high internal heat gains; high air change rate requirements; equipment exhaust requirements; and high fan energy. more
While overall data center efficiency can be increased through server virtualization and consolidation efforts, the use of these technologies is also pushing many data centers’ power and cooling densities beyond their original infrastructure capacity. These trends, along with the EPA’s recent report on data center inefficiencies, have caused many data center owners to reevaluate the design of their facilities and to look for innovative ideas to optimize their next generation mission critical facilities.1 more
The movement to provide more sustainable school buildings continues to grow. At the same time, the Sept. 11, 2001, terrorist attacks and recent campus shootings are driving education institutions to construct safer campuses and more secure buildings. Although these movements appear to have little in common, they complement each other in several areas. more
The reemergence of our core cities as more active and vibrant communities brings pressures and challenges to those who design. The density of buildings, traffic, the scarcity of land, and a competitive spirit among developers are all factors that work together to push modern buildings higher.
Sometimes, especially in motion pictures, we envision high-rise buildings as towering skyscrapers. While this is the romantic and not always incorrect vision, a “high” rise can be as short as eight to 10 floor levels. The National Fire Protection Association (NFPA) defines a high-rise building as a building with an occupied floor that is 75 feet above the level where the firefighting apparatus would stage firefighting operations. That low threshold requires several specific features to be designed into buildings to promote life safety and allow for emergency responders to safely and quickly access the higher levels of the building, thereby saving lives and considerable invested resources. With that fairly simple definition, all high-rise design challenges should be the same, right? Perhaps some additional discussion is warranted before we make that determination! more
The furor over compliance with United States Pharmacopoeia (USP) General Chapter 797, Pharmaceutical Compounding—Sterile Preparations,1 has somewhat subsided with the Joint Commission for Accreditation of Healthcare Organizations’ decision not to enforce its requirements. As of this writing, at least 10 states require compliance (in whole or in part). However, many facilities may desire to comply now to prepare for future federal, state or industry regulations. Operational modifications are the primary means of compliance, but the pharmacy’s HVAC system also must be evaluated. USP 797 offers some confusing requirements for HVAC system designers, but compliance in an existing facility is not as difficult as it may seem. more
In its purest form, water is one of the most aggressive solvents known and will dissolve a material until the solution reaches saturation. Pure water is also a critical ingredient in many business ventures; manufacturing, power generation, health care, pharmaceuticals, research, food production and processing, etc. Each of these business sectors has a different but specific use for high purity water. Water purity is relative to its use. Different industries have different critical levels or types of impurities; microelectronics – TOCs (total organic compounds); power – silica; pharmaceutical – bacteria; research –conductivity/resistivity.The specific purity needs, along with the analysis of the source water, form the basis of treatment to produce high purity water. more
The Centers for Disease Control and Prevention (CDC) is undergoing significant changes at its Atlanta campuses. With many of its buildings constructed in the 1950s and ’60s, the main campus now requires facility upgrades to improve its ability to fulfill its missions, which include being a national leader in research and response to the threat of bioterrorism. more
If a desktop computer had the capability to transmit data at 10 Gigabits per second, one could transfer an entire DVD movie in 30 seconds-a movie that otherwise would require two hours to consume. The speed of 10GBase-T is so much greater than 1000Base-T that it dwarfs the speed at which modern hard disk drives read and write to the system bus.
When hardware that can use this technology becomes commercially available, the opportunities for working directly from centralized data storage will be possible. This can potentially change the concept of using local storage. If used in a current desktop, the computer would quickly become overwhelmed with data. more
In the pursuit of science, competition for the best and the brightest minds has become fierce. Institutions and organizations often use laboratory facilities as recruiting tools to lure top researchers to their team. Today’s laboratories emphasize architectural design by featuring natural light, open floor plans, and flexible layouts, while at the same time promoting comfort, collaboration and productivity. more
The latest edition of the Guidelines for Design and Construction of Hospital and Health Care Facilities1 will be published this month. With assistance from the U.S. Department of Health and Human Services, the Guidelines is revised periodically and published by the American Institute of Architects Academy of Architecture for Health, and Facility Guidelines Institute (FGI). The Guidelines provide minimum ventilation for health-care facilities. The Guidelines also are adopted or adapted and enforced by 42 states and the Joint Commission on the Accreditation of Healthcare Organizations. The 2006 edition has some notable changes to the ventilation and ventilation-related recommendations. more
The design-build delivery method was used for the U.A. Whitaker Biomedical Engineering Building at the Georgia Institute of Technology, and the schedule was aggressive: 18 months from beginning of design until substantial completion of construction. Although Leadership in Energy and Environmental Design (LEED) Green Building Rating System certification was not a project requirement, the building still has many green elements. This article describes how the design-build team incorporated green concepts into this non-LEED project, and highlights sustainable features of the architectural, electrical and HVAC systems. more
Emory University has had a long history of providing quality cancer care, research and medical training since its clinics first opened in 1937. Unfortunately, cancer remains one of the leading killers of Georgians, and Atlanta is one of the largest cities in the country without a National Cancer Institute designated “Comprehensive Cancer Center.” When Emory University’s Woodruff Health Sciences Center set out to change that, it realized that a new home was required to meet its potential, and the Winship Cancer Institute (WCI) project was initiated–focusing exclusively on cancer research, and serving cancer patients and their families. The new WCI is a powerful tool in the fight against cancer and represents not only cutting edge healthcare design, but leadership in sustainable design and construction.
Many groups in the facilities industry are becoming aware of the greatest potential of the commissioning revolution—retrocommissioning. Retrocommissioning is the systematic process by which owners ensure that their buildings and their systems are optimized to perform interactively to meet the current operational needs as closely as possible. This process may include remedial design and construction to accomplish this goal. more
In the old days, telecommunications consisted of only the telephone network, and the design services were provided free of charge by the local telephone company. The internal personnel responsible for this design were known as the BICs, or building industry consultants. The fee for this design was covered by telephone subscribers as a part of their regular service.
Back then, coordination was not a major concern. BICs would work with architects and engineers in the planning phases and continue throughout construction by working with the contractors.
But all of this changed with industry deregulation in 1984. Not only did it break up the phone company into the regulated bell operating companies for local service, with AT&T continuing to provide long distance, but it also shifted the ownership of the cabling in a facility to the customer. more
On the surface, vivariums housing rodents are very similar in function, use, and frankly, design. Generally, they include holding rooms, procedure rooms, cage washing facilities, necropsy, and various other support spaces. Likewise, heating, ventilating and air conditioning (HVAC) systems serving these spaces can also be fairly typical. more
In its simplest sense, commissioning verifies that systems operate in a manner consistent with construction or procurement documents. This includes identifying and labeling devices, cabling and equipment; cleaning; preparing O&M documentation; testing and adjusting; and training personnel more
Despite the recent scrutiny and criticism of primary-secondary chilled water pumping systems, many owners still decide these systems are appropriate for their facility. Factors such as simplicity, familiarity, and experience are considered, in some cases, to have benefits to the owner that overshadow efficiency and first costs. Primary-Secondary pumping is not appropriate for all projects, but when the decision has been made to use it, properly addressing technical aspects of such designs and adequately addressing facility users’ needs significantly contributes to the project’s success. This article explores key issues to consider when designing a primary-secondary chilled water plant. more
When the U.S. Environmental Protection Agency classified environmental tobacco smoke (ETS) as a Group A carcinogen, many state and local codes began requiring restaurants and entertainment facilities to provide designated smoking areas that prevent smoke from being recirculated to nonsmoking areas.
For consulting engineers, these smoking areas open up whole new concerns—and special commissioning needs. The following case study is a primer on HVAC commissioning with special attention to smoking areas in these venues. more
