It’s a fact! No wall finish provides better fire protection, sound control or design flexibility than plaster. Chicago Plastering Institute 5611 West 120th Street Alsip, IL 60803 708-371-3100 Fax 708-371-8290

Today’s plaster walls may be made with conventional plaster and lath, or a faster and more cost-efficient veneer plaster system. Either way, plaster’s tougher surface means that it stands up to abuse better than any other interior finish. And only plaster can offer detailed ornamental treatments, and mouldings that look better, install faster and actually cost less than wood alternatives. For more information about plaster systems and the best professionals to apply them, call us.

LEGALISSUES

LIABILITY IMPLICATIONS ARISING FROM “RETAINED CONTROL” OF WORK by Shawn E. Goodman, Sabo & Zahn, Attorneys at Law

ast year, an Illinois appellate court held that a company serving as construction manager was not liable in a personal injury case brought by a worker employed by a subcontractor which did not contract with the construction manager.1 The case had to do with a project owned by a school district. The school district hired Turner Construction Company to serve as construction manager in the construction of a new high school campus. As set forth in its contract, Turner was required to help prepare the construction contracts, provide advice when it came to accepting subcontractors, and review and coordinate safety programs of contractors. However, importantly, the construction manager’s contract with the school district expressly did not include direct responsibility for construction means and methods and/or job site safety. Turner’s contract was with the school district. Turner did not contract with any contractors or subcontractors. The school district, meanwhile, hired a separate and distinct contractor which, in turn, subcontracted some of the work. In 2003, during the course of construction, the plaintiff, who worked for the erection subcontractor, was hurt on the job in the course of unraveling some steel cable. The erection subcontractor, Linden Erectors, was hired by Waukegan Steel, which directly contracted with the school district. The plaintiff sued a number of parties, including Turner, asserting liability in negligence, based on control of the jobsite, and by way of premises liability, based on possession of the actual property. The injured worker alleged that the construction manager was liable for construction negligence under section 414 of the Restatement (Second) of Torts. Section 414 reads: One who entrusts work to an independent contractor, but who retains control of any part of the work, is subject to liability for physical harm to others for whose safety the employer owes a duty to exercise reasonable care, which is caused by his failure to exercise his control with reasonable care. “Retained control,” meanwhile, is explained in comment (c) to section 414: In order for the rule stated in this Section to apply, the employer must have retained at least some degree of control over the manner in which the work is done. It is not enough that he has merely a general right to order the work stopped or resumed, to inspect its progress or to receive reports, to make suggestions or recommendations that need not necessarily be followed, or to prescribe alternations and deviations. Such a general right is usually reserved to employers, but it does not mean that the contractor is controlled as to his methods of work, or as to operative detail. There must be such a retention of a right of supervision that the contractor is not entirely free to do the work in his own way. Section 414 provides exceptions to the rule that one is ordinarily not liable for actions undertaken by independent contractors. Pursuant to the exceptions, one who employs an independent contractor can (Continued on page 8)

LEGALISSUES (Continued from page 7)

nevertheless be liable for that contractor’s negligence if control While O’Connell concerned a construction manager, it is is retained over the contractor’s work. In the alternative, and in worth noting because sections 414 and 343 are sometimes the absence of such control, an employer can still be liable if it used to try and assert liability against those involved in design, assumes supervisory duties and fails to use reasonable care in such as architects and engineers. In Madden v. F.H. Paschen, 916 N.E.2d 1203 (1st Dist. 2009), for example, a worker was exercising them.2 Either way, the scope of liability is based on the scope of the employer’s undertaking. Furthermore, such an hurt after falling into an orchestra pit. The defendants included employer must have known, or had reason to know, of danger both a design consultant and a construction manager, both of posed to the contractor’s workers. whom avoided liability. The appellate court affirmed this lack of The court in the O’Connell case concluded that Turner did liability, finding that neither entrusted work to an independent not entrust the independent contractors with any work. The contractor as required by section 414. Furthermore, the court court noted that the plaintiff was employed by a subcontractor went on, there could be no liability as to either defendant hired by another because there was contractor, which “The court in the O’Connell case concluded that Turner did an absence of had previously been evidence to show not entrust the independent contractors with any work.

Accordingly, they could not contractors or subcontractors and was thus not entrusting the be liable for negligently performing in a supervisory role. work to others as required by section 414. Because When it came to section 343, the Madden opinion noted that the defendant cannot be liable under section 343 unless it entrustment is necessary in order for liability to attach, Turner possessed the land at the time of the accident. The court could not be liable under section 414. Whether or not the further took notice that “possessor” is defined in the construction manager exercised “control” over the site was Restatement as “a person who is in occupation of the land not relevant. Control alone does not mean liability pursuant to with the intent to control it.” This requirement, that a section 414. defendant be a “possessor,” is often overlooked when taking The plaintiff’s premises liability claim, on the other hand, up section 343 claims, but is, emphasized the Madden court, was premised upon section 343 of the Restatement, which essential before liability may be imposed. provides: Together, the Madden and O’Connell cases supply guidance A possessor of land is subject to liability for physical harm about the exposure which can be created for a party with caused to his invitees by a condition on the land if, but only if, he: oversight or consultative responsibility on a project.

The Frozen Ivy by Robert G. Stanton, CPCU, ARM, RPLU of Willis A&E

The Higher Education (THE) Architects specializes in providing innovative design services for institutions of higher learning. Having opened their doors five years earlier, they had a growing reputation for their specialization in working with colleges and universities. They ran through the Request for Proposal process and were retained by Prestigious University (PU) to perform design and construction phase services for the construction of a new dormitory on campus. THE’s retention was a bit of a surprise as PU was notorious for only hiring their alumni to perform design and construction work on campus. PU had been using the same alumni-owned architectural firm for years, but there were rumors of a falling out between the two sides, and THE was the candidate selected. (Continued on page 32)

So tell me what you don’t like about the code by Kelly P. Reynolds ALA Code Consultant

WHY CAN’T THE building codes be simple to understand? Why are there so many options? Why isn’t everything in one chapter for each use? They are confusing at times. Let me address some of the confusion and help you make sense out of the IBC format. ■ DEFINITIONS - Fire wall, fire barrier, what’s the difference? Aren’t all walls firewalls? When you see italicized text in the code, that is your signal to go to Article 2 Two: Definitions. FOR EXAMPLE, using the wrong type of wall system can be the difference between creating separate buildings or having to bring an entire existing building up to the current building code. I would say that more than 50% of the code questions I receive

from our subscribers have to do with definitions. Getting the correct code definition can save you time and money in both design and building. ■ MIXED USES - Don’t all uses have to be separated? No, they don’t. Look at Table 508.4 (2009 International Building Code) and notice that many uses do not require separation. For example, between an Assembly (A Use Group) and Education (E Use group) there is no separation required. Why, you ask? Because they are both the same degree of hazard high occupancy load, restricted construction limits, etc. Don’t think that every tenant space requires a fire-rated separation. That is just over design and wasting money. ■ FOOTNOTES - Read the footnotes on all tables. Many times they give you exemptions that can benefit your project. For example, Table 601 (2009 IBC) note "a" roof supports permits you to reduce fire ratings of structural frame and bearing walls by one hour when supporting the roof only. ■ TRADE OFFS & OPTIONS - So, you have to sprinkler the building. But are you taking all the options available? You may be able to reduce the construction type, not rate the corridors and make a larger building with lesser materials. The I-Codes are performance based meaning that you can make changes on construction type, fire separation and numerous other options. This lets the designer use various options in the code to achieve a code compliant result. All these trade-offs help the bottom line in the cost of construction.

ADAADVICE

The Ides of March and ADA by Kimberly Paarlberg, RA, Staff Architect, ICC

The soothsayer's warning to Julius Caesar, "Beware the Ides of March," has forever imbued that date with a sense of foreboding. With March 15, 2012, being the effective date for the Department of Justice (DOJ) adoption of the 2010 ADA Standard for Accessible Design, some architects and building owners have begun to have the same apprehensive feelings in 2012 as the soothsayer did in 44 BC. DOJ officially published in the September 15, 2010, federal register their adoption of the 2010 ADA Standard. With input from the American Institute of Architects (AIA), DOJ allowed 18 months before requiring mandatory compliance for all new construction and alteration; thus the March 15, 2012, effective date. The DOJ intended the delay to allow projects already in progress to be completed using the 1994 requirements. However, architects could start using the 2010 requirements at any time. While there are differences between the 1994 and 2010 accessibility requirements, for architects who have been using the International Building Codes® (IBC) and the referenced technical standard, ICC A117.1 Accessible and Usable Buildings and Facilities, many of the revisions will be something they already have used in their design process. This has been an easy transition, as the 2010 ADA Standard is written more similar to a building code style and format. There have been extensive coordination (Continued on page 14)

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

ADAADVICE (Continued from page 13)

efforts between the International Code Council (ICC) and the U.S. Access Board throughout their development processes. For example, the two differences that most designer’s notice first between the 1994 and 2010 ADA are the changes to reach range requirements and the clearances at water closets. These changes were incorporated in the 2003 edition of ICC A117.1. For single occupant bathrooms, it is important to look at the requirements for the room as a whole. So, while the change in water closet clearance may first appear to have significantly affected the room, with the revisions for door allowances, the overall increase in room size is extremely minimal. DOJ has provided multiple examples of this in their explanatory guidance at http://www.ada.gov/2010ADAstandards_index.htm. See example below: It should be noted 1991 Standards that the 2009 ICC 3’-0” min A117.1 has a whole new chapter on recreational facilities coordinated with the new requirements in the 2010 ADA Standard. It is also important to note that the DOJ regulations include some additional requirements not found in the 2010 ADA standard. While some Plan-2A: 1991 Standards Minimum with In-Swinging Door deal with operation issues, such as 5’-0” x 8’-6” = 42.50 Square Feet ticketing policies for 2010 Standards wheelchair accessible seating, others can 5’-0” min affect building design. One example is that DOJ regulations will require elevator access between stories in dormitories at places of education. Also, the accessibility requirements for dormitories will be the same, regardless if the dorm rooms are Plan-2B: 2010 Standards Minimum with In-Swinging Door configured in the old style of double 7’0” x 6’6” = 45.50 Square Feet occupancy rooms or the new style that may closely resemble apartments; and regardless if the dormitories are owned by the university or if the dormitories are privately owned but operate with the university. Another

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

example is that DOJ regulations will increase the number of Accessible housing cells in jails from 2 percent to 3 percent, as well as require distribution by classification. The ICC’s Code Technology Committee (CTC), was established by the Code Council’s Board of Directors in 2004 to evaluate and incorporate new technology and concepts into the I-Codes and to make proposals for new changes as may be necessary. A special CTC study group examined the differences between the 2010 ADA Standard and the 2012 IBC and 2009 ICC A117.1. This next code change session will include a variety of changes proposed through this study group. The Group A Code Development Hearings will be held in Dallas from April 29 through May 6. As always, all meetings are open to the public, and anyone can testify. If you are unable to participate in person, the hearing will be broadcast live on the ICC website. All proposed code changes will be posted on the ICC website on March 12, 2012. If you are interested in getting additional training on the new ADA requirements and/or the ADA/IBC coordination, the ADA Technical Assistance Centers are holding their annual National ADA Symposium in Indianapolis May 30 through June 1. For additional information, visit the website at http://www.adasymposium.org/IndianapolisSymposium.html. ICC and the United States Access Board will be among the presenters. One of the goals of the Code Council is to continue to coordinate with the federal accessibility requirements for buildings included in the Americans with Disabilities Act and the Fair Housing Act. At the same time, the 3- and 5-year update cycles for the ICC and A117.1, respectively, allow for new concepts and innovations to be incorporated into the IBC and A117.1, which is sometimes faster than the federal regulation process. In conclusion, while the Ides of March might have been a bad day for Julius Caesar, it does not have to be a day of foreboding for architects, designers and building owners. The ongoing coordination between ICC and the U.S. Access Board instead will allow an easier path to designs that provide equal access for ever yone, while still allowing for design freedom.■

George Washington Carver Academy Waterloo, Iowa INVISION devised a design concept centered on the promotion of specialized learning and high levels of engagement, a requirement of the STEM curriculum, with the integration of sustainable elements throughout. Each grade level is separated into technology-rich learning studios radiating from the media center. Communal resource areas create flexible space for learning outside of the traditional classroom. In addition to the community wing of the building, a public health clinic and greenhouse serve as resources for both students and the community.

Mercy Medical Center: Pediatrics Renovation – Phase 1 Des Moines, Iowa INVISION collaborated with Perkins+Will to transform the first phase of the Pediatrics north tower and E-Zone from a somber and dated facility to a light-filled, modern healing environment. The dramatic change was achieved by incorporating a colored glass curtainwall, as well as clean white and maple finishes with one of three, gender-neutral and age appropriate color schemes. Home-like touches and amenities were incorporated in the central E-Zone, which houses the Ronald McDonald House, a source of support for patient families.

Through renovation and addition efforts, INVISION redefined the starting point of the NICC experience—the Student Center. The twostory addition, housing a new bookstore, offices, and a library, is connected by open balcony areas accessed through a cozy Reading Room. A commons area links the original structure with the addition, providing space for a dining and lounge area served by a new kitchen. The outcome is a must-stop hub for campus, centralizing student services and creature comforts under one roof.

University of Iowa: Dental Science Building – Phase 1 Iowa City, Iowa The addition to the Dental Science Building is the first phase of a three part project that will modernize the building to become a cutting-edge facility for dental education. INVISION succeeded in forming the needs of 18 distinct groups into one, patient-centered solution. The renovation adds sophisticated clinic and student areas, as well as updates to the existing clinic and laboratory spaces. INVISION successfully guided this project, managing the phases to ensure minimal disruption to the building’s occupants who remained during construction.

Marshall-Waters-Woody, located in Springfield, MO, is a small firm with large capabilities has been producing architecture and advising clients for 50 years, meshing traditional, personal experience with modern, high technology. Marshall-Waters-Woody has extensive experience in a variety of building types including residential, commercial, educational, institutional, financial, governmental, industrial, medical, religious and theatrical, to name a few. Established in 1962 by the partners Ed Waters and Bob Marshall, the firm expanded in 1979 with the addition of Bill Woody as partner. Hands-on direction by the firm’s principals and computerized integration of design elements ensure sophisticated quality control. Providing a broad range of services, Marshall-Waters-Woody focuses on the future with specialization in task and talent that brings efficiency and creativity to the firm as a whole. The materials of which a building is composed are nothing more than sterile elements devoid of grace and life. Yet, when combined, these elements form architecture, of which no other art form is more intimately entwined with man’s daily existence. Born of form, function, static solidity and fluid creativity, architecture is, in all ways, living art. Since 1962, Marshall-Waters-Woody has made buildings come alive for those who live and work in them. They realize that good architecture is not a fashion or a fad, but an enduring creation that is universal and timeless. They measure their achievements in clients, rather than awards. Architecture succeeds only when it ceases being an expression of a designer’s personality or whim, but instead, represents the environment and people in it. The firm’s commitment to sustainable design dates well before the "green" movement and is committed to conserving our environment thru membership and association with the USGBC and the International Institute for Bau-biologie & Ecology. The LEED accredited designers on staff are sensitive to incorporating sustainable design in every aspect of a project.

The congregation of this historic 1879 church had out-grown their existing building. Needing more space, the addition added a new parish hall, classroom and office space. Indiana Limestone, matching the existing limestone, was used along with a covered cloister, lined with stone arches, to tie the addition and the existing building together. Heavy timber modified hammer beam trusses were used to span the 50 foot wide parish hall, emulating the wood trusses in the original chapel. The new commercial kitchen allows serving both congregation and community.

Major Changes to the 2012 International Building Code by Kelly P. Reynolds ALA Code Consultant

There were hundreds of proposed code changes during the last cycle, all did not get adopted. With this edition of Licensed Architect, I will begin explaining some of those changes to the 2012 International Building Code. So let’s get started... DEFINITIONS • Definitions have been moved from other locations in the code to Chapter 2. • Defined terms are still listed in their respective chapters but refer back to Chapter 2. • All defined terms are italicized throughout the code to remind users there is a definition for them. OCCUPANCY CLARIFICATIONS • 303.1.3 - A room or space used for assembly purposes in Group E is not considered a separate occupancy. Chapter 11 accessibility and Chapter 10 egress requirements for assembly occupancies still apply, but the mixed occupancy provisions of Chapter 5 do not. • 303.4 - Casino floor occupancy classification is now clearly A-2, food and drink consumption, due to the same characteristics of distracting light, sound and unclear egress paths. • 303.3, 306.2 - Commercial kitchens serving large restaurants are now considered A-2 occupancies. Only kitchens with no associated dining areas are to be considered F-1, such as catering uses. The separation requirement has been eliminated from Table 508.4. CARE DEFINITIONS AND REQUIREMENTS REVISED • Comprehensive revisions were made in Chapter 3 to define and clarify medical care, custodial care and personal care. • Medical care is primarily I-2, where 6 or more people incapable of self-preservation are receiving care. When they do not exceed five patients, it may be Group R-3 or regulated by the 2012 International Residential Code.

(Editor’s Note: The five or less patient rules comes from a Medicare rule that lets that number stay in a private residence for care.) • Custodial care is primarily I-1 (17 or more occupants) and personal care is R-4 (6-16 occupants). All must be capable of self-preservation. Both care definitions are similar and do not include medical care. CHAPTER 4 - SPECIAL OCCUPANCIES • 402 - Open Mall Buildings, first defined in the 2009 IBC and becoming increasingly popular are now given a variety of changes including the new concept of a open mall building perimeter line that defines what is within a mall. This section was reorganized along topics with all egress in 402.8 and all construction 402.3. • 407 - Regulations require that were in Chapter 10 regarding patient care suites proliferating in hospitals are now revised and relocated to 407. • 410 - Fly galleries, gridirons and pinrail terms have been consolidated under a new definition: technical production area. Most of Chapter 10 exit requirements, except for reference to Table 1015.1, have been relocated to this section. Some smaller stages are now allowed only one exit. • 424 - Children’s play areas, formerly only applicable to covered mall buildings, now have their own section and regulated regardless of the building in which they are located. Use of NFPA 289, an alternative to UL 1975, is allowed for testing foam plastics and pool balls that are commonly used in these play structures. CHAPTER 5 - HEIGHTS AND AREAS • 501.2 - The Fire Official is now allowed to require additional locations for building ID and the numbers must be maintained. • 505.2.2 - Mezzanine egress is now required per Chapter 10 with no special provisions allowed. ☛ Next Month I will continue with the changes to the 2012 International Building Code.

INSURANCEINFO (Continued from page 11)

The dormitory was supposed to include suites with multiple bedrooms and bathrooms. The college was experiencing a rapid exodus of students from the dorms to apartments off-campus, and wanted to stem the trend of off-campus living. It was felt that suites, which were more like the apartments off campus, would go far in enticing students to stay on campus. The University presented THE with an AIA agreement, but upon review the architect noticed that almost every clause had been substantially altered. One of the conditions was for THE to guaranty the project when completed would meet a LEED Silver Certification. Also, the alternate dispute resolution included Arbitration. THE was required to transfer ownership of the design and documents to PU upon payment of fees. THE knew some of the provisions were problematic; however, they felt the project was a "choice" project in its market place and signed the contract as drafted. After all, the project was located in their home town. As part of their duties and responsibilities under the contract, the architect was "required" to retain all subconsultants. In the details, it was specified that THE was supposed to specifically retain Alumni Mechanical, an HVAC subconsultant preferred by the client. One positive exception to the retention of sub-consultants was PU would directly retain the geotechnical engineer. The owner of Alumni was a noted football player from the school as well as president of its alumni association. THE agreed to retain Alumni, and used a basic letter agreement to facilitate the retention. The letter agreement provided the basic information relative to the project, and the sub-consultant’s role as an HVAC consultant. THE had standard terms and conditions they used on their contracts, which had been recommended to them by their broker. Those terms and conditions were attached to and made part of the letter agreement by reference to them in the letter agreement. During the initial planning meetings, THE immediately felt like they were on the outside looking in at the other parties to the project. Most notably, THE became increasing uncomfortable with the high level of communication between the client and the owner of Alumni. At one point, the project architect was advised of changes to its design which had been recommended by Alumni and agreed to by PU, but not communicated through the architect’s offices. THE made no mention of the communications gaps for fear of creating problems with the client. PU had recently received a substantial donation from a celebrity who claimed to be an alumni of the school, and had indicated to THE how they planned on doing a great deal of expansion on campus over the next several years. The design was completed and approved/permitted. However, before the first shovel hit the ground, the client opted to terminate THE’s services relative to site observation duties, indicating they would be called only if there were issues with the design. Surprisingly, PU offered to pay for these services on a time expended basis. Instead, PU reported that they had hired a construction manager to perform site duties, another alumni. The architect advised PU that it would finalize its billing and retire the project file. PU paid the bill and the project file was closed.

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

No one ever called THE for clarification of any of its designs or contract documents. THE personnel still ventured to the jobsite on occasion to determine how the project was progressing, but did not prepare reports or talk to anyone on site. The project was completed on time and within budget. PU and the community considered the project a big success. Shortly after the facility was opened, THE won an award for the design. The following school year started without problems. However, as the temperature dropped during the winter months, things took a bad turn. The college officials started receiving complaints from the residents in the suites that the rooms were too cold. A college official attended several of the dorms and verified rooms were being heated properly. One student went so far as to display a glass of water she had put next to her bed before going to sleep. When she woke up in the morning, the water was frozen solid. After receiving a substantial number of complaints, the college officials called the architect, who attended at the site to conduct an investigation. During the investigation, it was determined the dampers were direct flow-through vents which did not disrupt the flow of cold air from outside into the units. The installed vents were not the same as those specified by THE. The project architect had specified dampers which would have prevented the cold air from coming directly into the room, allowing the air to be heated prior to entering the room. The HVAC system installed did not have the capacity to handle the high rate of cold air flow given the direct-flow nature of the vents. When the architect advised the vents weren’t the ones he had specified, the college official replied, "That’s not all." The college official also brought the architect outside to show him there was a black and green sludge drooling down the outside masonry walls, potentially damaging the exterior masonry work. Standing next to THE’s principal, the college official asked, "What do you make of this?" The architect said nothing. He later indicated, "I have been told never to admit liability, so I said nothing." Two days prior to the running of the Statute of Limitations, PU filed a demand for arbitration against THE based on professional negligence and breach of contract. The contract between PU and THE required Arbitration as the dispute resolution mechanism. During the course of the ensuing discovery, it was discovered that PU had also agreed to some substitutions recommended by Alumni for materials and components without first getting input or approval from the architect. When THE made a demand that Alumni participate in the arbitration, the sub-consultant refused citing the fact they had no obligation to do so. In fact, the Alumni contract required mediation as the dispute resolution mechanism. Shortly after the arbitration began, Alumni closed their doors. When THE followed up, it was discovered Alumni never reported the claim to its carrier, and the policy had expired.■ If you have an interest in obtaining 1.5 learning units for the above article, please email Tom Harkins from Willis A&E at tom.harkins@willis.com.

Zhaga – LED Light Engine Standardization Is Here by Ben Swedberg of IDEAL Industries, Inc.

Learning Objectives: After reading this article participants will be able to: 1. 2. 3. 4.

Explain the history of LED Lighting Describe the main goals of the Zhaga Consortium Summarize the importance of thermal management Define the common terms used in LED lighting.

Executive Summary Visible LEDs have migrated into various product areas since their beginning 50 years ago. The current market into which they are poised to play a major role is Interior Lighting. One challenge for that application has been how to provide adequate thermal management to maximize lumen output and ensure long-life while at the same time provide easy enduser replacement. This article will provide the reader with answers to common questions related to this subject and to why the architectural community will soon be able to confidently specify great performing LED products that are easy to change in the field. History of LED Lighting After Nick Holonyak invented the practical visible LED in 1962, the first commercial products were limited in brightness and only to applications such as red indicator lights and seven segment displays. In the 1970’s, yellow and green LEDs joined the family and were designed into products such as calculators, but still were not able to produce ambient light. In the late 80’s to early 90’s, LEDs took large leaps forward, with the first blue LEDs, the advent of high brightness capability, and the use of phosphor coating to create white light. Technological improvements enabled even brighter LEDs, which enabled the move into progressively higher lumen applications: flashlights, signage, brake lights, traffic lights, and finally ambient lighting applications. Today, LED lighting products offering more than100 lumens per Watt (LPW) are not uncommon and provide very efficient energy use compared to traditional light sources. These LED products are showing up in all types of form factors with some fitting into traditional sockets and some using custom interfaces. A visit to the annual Lightfair tradeshow will make it clear that just about every company is now offering LED products with ever increasing light output and efficiency. The challenge today is to optimize LED Lighting performance in a product that is convenient for the building occupant. FAQ #1: But LEDs last forever, why do we even care about enduser replacement? The answer is that most of them last a very long time, but not all of them, so they must be replaceable. Many early LED

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

luminaires were designed with the LEDs permanently affixed to the luminaire to maximize light output and thermal efficiency. This was considered acceptable because LEDs can last 50,000 hours and longer. LEDs are indeed capable of long service lives, but like all electronic products, they still have infant mortality rates and are susceptible to damage from broom handles, forklifts, and water leaks. They need to be replaceable by the building occupant if we want efficient LED technology to succeed in broad applications. Also, when more efficient Light Engines become available, does it make sense to swap "lamps" or replace entire luminaires? The DoE’s Designer Roundtable on the subject cited replacement parts and lack of modularity as major drawbacks to LED adoption. NEMA recognized this in its 2009 white paper, LSD 44 "Solid State Lighting—The Need for a New Generation of Sockets & Interconnects": "Currently, in many LED fixtures, the LEDs are considered "permanent" and cannot readily be replaced in the field by end users or field service personnel. Some LED fixtures treat the LEDs as parts of sub-modules that could be replaced, but are not necessarily constructed in a manner for a "simple" swap without major disassembly of the fixture…. Growing experience with LEDs shows that failures do occur…" FAQ #2: If LEDs are so efficient, why is thermal management important? It does seem contradictory that a high efficiency product needs its heat output well managed. Actually, LED products produce much less heat than traditional light sources. The difference is that the heat produced in an LED product is highly concentrated at the LED itself and thus creates a very small area of high temperature. The LEDs have a Critical Temperature at which their life will be greatly affected. Good luminaire design requires a product that reliably stays below this temperature and yet maximizes light output. Traditional lamps with Edison bases, or CFL pin-bases, etc. were not designed to help conduct heat away from an LED inside a lamp. Consequently, LED light sources that use these traditional interfaces have to sacrifice either lamp life or lumen output. NEMA recognized this in the same white paper: "The use of existing sockets compromises the capability of solid state lighting. Existing sockets are sub-optimal mechanical and optical configurations. Existing sockets do not provide an adequate thermal path." So, LED product development for general illumination initially followed two different paths: 1) using traditional lamp bases for easy replacement and 2) using integrated luminaires for great performance. As already mentioned, the first addresses the replacement market well, but is limited to products that cannot properly manage heat and thus will sacrifice product life, lumen output, or both. The second option provides the very best

Association of Licensed Architects Continuing Education performance, but makes field replacement more challenging. Then came LED Modules. Modules allowed easy replacement and also were designed to provide a good thermal conduction path away from the LEDs. These seemed to bridge the missing gap, but then market acceptance was slowed since each was a proprietary system, with a unique size and mounting. The Creation of Zhaga This brings us to March of 2010, when a group of lightingrelated manufacturers from around the world first met to form the Zhaga Consortium. Zhaga is an industry-wide cooperation aimed at the development of standard specifications for the interfaces of LED light engines. The goal of the group is to enable interchangeability between products made by different manufacturers. As the Zhaga website states: "Interchangeability is achieved by defining interfaces for a variety of application-specific light engines. Zhaga standards will cover the physical dimensions, as well as the photometric, electrical and thermal behavior of LED light engines. Zhaga is established for the benefit of the consumers and professional buyers of light engines and luminaires, in the expectation that standardization will prevent market fragmentation into incompatible products. Zhaga standards will increase the confidence to specify and purchase LED products that will be easily replaceable and commercially available, while continuously enjoying the performance upgrades that LED technology enables. In addition, this will foster innovation and competition in the application of LED lighting in general." Zhaga companies have already made great progress in several applications, including down lighting, spot lighting, street lighting, and ambient lighting (such as linear fluorescent). For each of these, Zhaga is defining four interfaces between the Light Engine and the luminaire: mechanical, electrical, thermal, and optical. The Zhaga specifications only define the outside of LED light engines. Zhaga treats light engines as a "black box", with defined interfaces that do not depend on the technology used inside the light engine. This enables maximum innovation within products, while assuring a mating interface on which users can rely. In order to create standardized LED options that can be specified in the near future, the Zhaga Consortium is working at an incredible rate. In less than two years, the Zhaga companies have already met 13 times and have planned 6 more meetings in 2012. The Zhaga Process The Zhaga process uses a multi-phase approach to assure all ideas are shared openly so that specifications provide reliable interfaces while still maximizing the design freedom of LED technology. In the first phase, member companies present proposals for a product type for which they envision the need for standardization. There may be several proposals from different companies all for the same use applications. Then the members form a Task Force of volunteers who review each proposal and work to develop a specification framework that takes the best elements from each. The Task Force then asks the consortium members to vote whether they can form a Work Group to develop a specification. Upon approval by the members, the specification begins to

take concrete form. Once the specification seems set, the Work Group requests that manufacturers build prototypes to meet the draft specification. The prototypes are then reviewed for interoperability and any issues found will be addressed with updates to the draft. Once the work group has a draft that is robust, they will submit it to the consortium members for a vote on whether to publish as a specification.

During the early period after the specification is approved, members may find improvement opportunities and will submit them to the work group for review prior to vote by the members. It is essential that any changes be compatible with earlier versions of the specification in order to reliably mate with products already available in the market. This provides assurance to the specifier community that the interfaces that come from Zhaga can be relied on in the future. Approved Zhaga Specifications Zhaga members have shown a sense of urgency and have approved several specifications already. Member companies are developing products to meet these specifications now, and specifiers can be assured that these products will be compatible with replacement products developed in the future. The following describes the significant activity.

for dimming, but will cooperate with NEMA to establish a dimming interface standard that is suitable for LED Light Engines. What Will Make Zhaga Successful? Besides robust standards, Zhaga is putting into place both a mechanism to inform the user-public about these standards and also provide assurance through third-party testing that the products meet the requirements. In 2012, the Zhaga logo (see below) will begin to appear on numerous products to communicate compliance to Zhaga requirements. PROTOTYPE LED SPOT LIGHT MODULE WITH SEPARATE CONTROL GEAR (Images courtesy of Zhaga Consortium website, www.zhagastandard.org)

The first specification was approved in February 2011 for a socketable Light Engine with an integrated Control Gear (see images below) for down lighting applications. It is based on the Philips Fortimo Twistable, but has been adapted to meet regional requirements such as versions that can support universal input voltage (120/277V and 347V in Canada). Several companies provided prototypes and input to the development of the Light Engine and mating holder. The design creates a large thermal interface between the Light Engine and heat sink to enable the long-life and performance expected of LEDs, with replacement as easy as a quick twist. The second specification that was approved is for an LED spotlight module with the Control Gear located in a separate housing. As can be seen from the prototypes below, the physical size, and mounting of the modules is consistent, so that replacement in the field is simplified.

About 80 participants from 40 companies from Europe, Asia, and North America continue to attend each Zhaga session. The Zhaga companies will continue their attention and sense of urgency during the six meetings in 2012. Their goal is to create peace of mind in the architectural and facility management communities that reliable LED products can be specified soon and will be available from many manufacturers well into the future. Ben Swedberg is the Business Unit Manager for Engineered Solutions at IDEAL INDUSTRIES, INC. and continues to actively participate at Zhaga meetings. IDEAL has been a trusted manufacturer of electrical products for almost 100 years and is pleased to be participating within Zhaga to assure the successful transition toward LED Lighting in North America.

SCHEMATIC VIEW OF SOCKETABLE LED MODULE WITH SEPARATE CONTROL GEAR (Images courtesy of Zhaga Consortium website, www.zhagastandard.org)

The third specification that Zhaga members approved is for a socketable spot light. The control gear of this spotlight engine is again located in a separate housing. Where the previously approved spot light engine was meant for direct screw mounting, this new specification is allows for simple twist replacement of the module into the holder. See image below. Current Status As of the last meeting in November 2011, there were proposals for linear modules for both street lighting and indoor applications near completion. Zhaga established a task force earlier in 2011 to study how the dimming behavior of LED Light Engines can be specified such that the light engines become interchangeable in their dimming behavior. The task force's first priority is phase cut dimming. Zhaga does not plan to create a Zhaga specification

Control Gear (commonly known as driver): Acting somewhat like a ballast in fluorescent lighting, the Control Gear is made up of electronics that convert input power into the necessary power to drive the LEDs — often converting line voltage to lower voltage DC with either constant current or voltage output. The Control Gear also protects LEDs from spikes and fluctuations from the input power. Heat Sink: The part of the luminaire that conducts the heat away from the LED. Light Engine (LLE): The LED module and Control Gear taken as a whole. This might be an integrated assembly comprised of LED module and Control Gear in the same housing, somewhat analogous to a self-ballasted CFL lamp. It could also be a module and Control Gear in different locations within the luminaire connected by a cable, similar to linear fluorescent lamps with ballasts. LED Module (also known as an array): An assembly of LED dies on a printed circuit board, with means to connect electrically, mechanically, and thermally to the LED luminaire.

START SEEING DETAILS! Improving Details through Visual Thinking by Paul Whitenack AIA, LEED AP

Close your eyes for a moment and imagine a building that you have designed or detailed previously. How do you see the building in your mind’s eye? Most of us will envision a sculptural, three-dimensional architectural form; virtually tactile in our imaginations. Now picture the details that were prepared to construct that same building. Chances are, flat images consisting of black lines, hatch patterns, and a myriad of notes and dimensions come to mind. It seems incongruous that these characterless diagrams could serve as the descriptive basis of a sculptural and spatial architectural form that will be expected to withstand the elements for decades. It is also counterintuitive that, despite our visual thinking capabilities and regardless of the recent proliferation of three-dimensional computer software, architectural details continue to be largely conceived and expressed in this flat, twodimensional format. A fresh approach to the thought progression that we use to develop our details and the format in which they are presented seems to be in order. The motivation for improving our details becomes increasingly evident as architectural designs and construction methods grow more complex and weather patterns become more extreme. Well-visualized and effectively communicated STONE 1 4” INSUL - 2 details are the essential fabric of a high-performance envelope AIR BARRIER that protects the materials and contents of the building from REYNOBOND FASCIA PREFIN.

A typical construction detail, drawn by the author. documents involves recognizing and developing our inherent visualization skills to truly start seeing details. As illustrated by the opening example, most architects possess the unique ability to see with the mind's eye- to mentally perceive three-dimensional images without actual visual input. Regrettably, many architects fail to see the applications for this powerful cognitive tool beyond the design phases of a project. In particular, details for the building envelope can be improved considerably by using visualization techniques to think about the building in more holistic terms. Architects who have developed the capacity to carry the visual thought process typical of the schematic design phase all the way through development and documentation of the details are likely to produce better construction document packages featuring more comprehensive details. Here are three suggested approaches that focus on the enhanced use of visualization techniques as a means of improving building envelope details. Visualize the Primary Design Aesthetic The detailing process normally begins during the Design Development phase, after the architectural designer has established an overriding aesthetic for the building. The exterior cladding and its details typically constitute the aesthetic face presented by the building. Ideally, exterior envelope details should be simple and straightforward yet informed by an understanding of the basic design philosophy. Frequently the small, seemingly insignificant elements of the chosen cladding systems are overlooked, but they can add or detract significantly from the overall design aesthetic depending on the level of consideration given by the detailer. Rather than simply drafting a routine fastener or a panel joint in a detail, take a moment to fully visualize how the cumulative multitude of these elements will work in concert with the primary design aesthetic, giving consideration to:

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

• Patterns created by the spacing, alignment, color, and visual prominence of exposed fasteners. • Shadow lines and highlights presented by laps, accents, or reveals in panelized cladding systems. • Networks of visible lines created by the width and spacing of control and expansion joints. • Continuity of masonry coursing across projected flashing, control joints, and changes in geometry. • Sight lines that can either flow across the building or start and stop depending on the methods used to detail wall corners, parapets, bases, and other elements of transition. There are certainly many other variables that would also benefit from more thorough visualization, but the important aspect to appreciate is that details that are crafted to consistently reinforce the overall design aesthetic can often provide the difference between mundane and magnificent architecture. While it is important to incorporate design aesthetics into the visible details, it is essential that all details should first and foremost be devised for effective performance and long-term durability. Design considerations should not be used as justification to depart from industry standards or manufacturers’ recommendations regarding suitable material and product applications, methods of installation, spacing and placement of control or expansion joints, fasteners, flashings, and other elements that help form the building envelope. Visualize How your Details will Control the Elements While aesthetics are certainly an important consideration, the primary purpose of creating exterior details is clearly to control the elements as they converge about the building envelope. The major vehicles of envelope bypass initiated by weather and pressure differentials include air infiltration and exfiltration, liquid water leakage, vaporized water transport, and thermal bridging across materials of higher conductance. As the details are developed, try to envision how they will function as an assembly to mitigate the adverse effects of these processes. Because water leakage, vapor drive, air infiltration, and thermal conductance can all move through the building enclosure in multiple directions as they follow the paths of least resistance, it can be extremely difficult to successfully comprehend the shortcomings of envelope details if they are solely considered and presented in the traditional two-dimensional format. Learning to see the building enclosure in three-dimensional form will enable architects to recognize potential weaknesses in the enclosure system and respond with details that better convey the intended construction methods and sequences to the contractor. It is particularly important that we learn to focus our vision on the points where geometries and materials converge because the elements, especially water, will also converge in these locations. When selecting areas to detail, try to visualize how the envelope will function in the weather extremes of the building’s ultimate location in order to anticipate the methods and directions in which air pressure, vapor drive, and thermal variations will challenge the building enclosure. Too often, we

cut our details at the least complicated point of the assembly despite the fact that this is not the location where problems are likely to arise. For example, window head and sill details are typically drawn at some point in the middle of the opening, neglecting the critical transition points where the flashings terminate beyond the corners of the jambs. This oversight often results in the omission of flashing end dams, which can be a relatively simple yet extremely effective means of keeping water out of the wall cavity. Helpful exercises to develop a visual thought process that can improve details for more complete control the elements include the following: • Visualize how the wall assembly will collect and drain incidental moisture, avoiding unnecessary impediments to drainage while providing a smooth and uniform drainage plane. • Understand the method and direction in which the wall assembly will dissipate vapor (dry out), depending on seasonal and climactic influences. • Prevent thermal bridging and condensation by envisioning a complete thermal barrier between highly conductive elements like metal ductwork and structural steel, and the cold side of the building. Try to visualize locations that are often neglected by the insulator to ensure a complete thermal separation. • Accommodate the expected range of differential movement for cladding and substrate systems to prevent premature breakdown of sealants and stress-induced deformation or material damages. • Anticipate the effects of differential thermal cycling on adjacent materials, providing adequate separation and additional protection where required. Now that we have learned to effectively visualize how climatic elements can attempt to bypass the building envelope and the means by which our details will respond to this challenge, the next step on the pathway to seeing better details is to envision building enclosures that are durable, constructible systems featuring multiple lines of defense. Visualize Continuity and Constructability Even well-crafted details are of minimal value if they do not provide redundant and continuous layers of protection, or if they cannot be effectively built by the contractor. In fact, continuity and constructability go hand in hand. They are only possible when the designer understands the methods and sequences of construction and the contractor is aware of the importance of preventing even the smallest bypasses in the enclosure systems. Anticipating the areas where breaches in the envelope are likely to occur is easier when we visualize how and by whom the details will be constructed. Think back on questions that have arisen from contractors that have fabricated your previous details and attempt to address their concerns and incorporate relevant constructability advice as you develop new details. Consider and communicate the sequence of application and the methods of termination for the basic elements of the substrate including the flashing, weeps, and weather-resistive barriers, ensuring that these systems are installed and lapped in the proper sequence. Clear communication is especially important (continued on page 40)

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

CONTRIBUTEDARTICLE (Continued from page 39)

where adjacent components of the same detail will be installed by different subcontractors, as often occurs at interfaces where diverse substrate and cladding materials converge. These locations can experience water intrusion failures in the transition space between the work of different trades (e.g., the brick mason and the metal-siding installer). When the work of each trade stops at the edge of the material they have installed, but neither contractor has been asked to provide a connection or transition between the substrates behind their respective cladding materials, the result can often be an unsealed gap in the weather resistive barrier that extends for the full height of the building. Detailers must anticipate which trade is likely to install their work first, how the convergent substrate materials will be lapped and sealed, and whether the materials are chemically compatible for contact with each other. When in doubt, address any uncertainties by requesting a preconstruction meeting with all of the trades involved. Other instances where details require added attention to the continuity and transition between differing materials can be found where building masses collide or terminate, including soffits, overhangs, inside and outside corners, wall projections, intersecting parapets, and more. Try to envision and document these often-overlooked architectural elements by creating reflected ceiling plans of exterior soffits to show lighting, control joints, and vents; by providing cutaway isometric views of the saddle flashing where a low parapet intersects a higher wall, or by including detailed isometrics of the flashing and lap sequence for the substrate assemblies at window conditions. One final consideration to bear in mind is the essential, but often overlooked, connection between the details and the specifications. Regardless of how thorough and comprehensive our details can become, there will always be some aspects of documentation that are more suitably conveyed by the specifications. Despite this fact, discrepancies between the two are common. Ensure that the details and the specifications convey a consistent message, acting as complementary elements without repetition or contradiction. Likewise, ensure all parties involved in the construction process have access to the specifications and understand that their content is equally as important as the drawings. The complete package of information provided by effectively visualized details and coordinated specifications is the basis for a well-constructed building in which the owner, architect, and contractor can all take pride. Putting your Visions into Practice Once we establish a habit of developing details by learning to see them in the mind’s eye, how can we best put our newfound abilities into practice? In addition to visualization methods, what other tools and techniques can help us create details in a threedimensional aspect that can more effectively communicate our intentions to the contractor? Here are a few methods architects may use to develop and communicate their visions: • Hand sketched isometric drawings are helpful when considering the aesthetics of a detail and when envisioning how patterns formed by exposed fasteners, reveals, and control joints will continue around edges or corners. Sketch in

LICENSED ARCHITECT • VOL 16 NO. 1 • SPRING 2012

whatever style you are most comfortable, starting with broad, loose strokes and progressing to more detail and precision as the drawing develops. Include foreshortening and simple perspective where applicable, and ensure that you include a large enough sample area to get a true sense of the visual patterns created by the elements being considered.

Figure 2. Quickly rendered hand sketches can be used to help visualize details and spatial elements.

• Physical models are frequently used to study building forms; and they can be equally effective when devising details. Simple study models can be crafted using paper, cardboard, foam-core, Styrofoam, modeling clay, wood, or any material that can be shaped or assembled into forms to help architects fully visualize details. In the same way whole building models communicate our designs to the client, smaller scaled models displaying detail concepts may be a helpful means of communicating construction intent to the contractor. • Computer-aided drafting and three-dimensional modeling programs are powerful and effective tools for designing and documenting buildings. Unfortunately, these programs are still largely used to produce standard, flat, two-dimensional details. There are several possible reasons why this has traditionally been the case: A major impediment has often been presented by the limited amount of time available for detailing, coupled with budgetary constraints imposed on projects by downward pressure on architectural fees. There is also a tendency toward an institutional disconnect between the experienced architects who typically devise the details and the generally younger staff who are currently more proficient with computer modeling software. Regardless of the cause, exporting, re-drafting, and annotating sectional detail cuts from architectural and structural models created by building information modeling (BIM) software constitute a failure to utilize the software to its maximum advantage. In fact, Revit and other manufacturers of BIM software are continually adding tools and utilities—like Assembly and Parts Creators—to increase detailing capabilities of each successive software release. Digital snapshots of critical or complex detail areas produced by BIM software programs can be included to more effectively document conditions extending around corners or following complex architectural

Field testing for water leakage and air infiltration can be constructed on in-situ mock-ups to verify that the constructed enclosure system is working as visualized by the design team.

geometries. Other software platforms, like Google SketchUp and Autodesk Inventor, can also create effective modeled views for study or presentation of intricate areas that cannot be effectively conveyed in two–dimensional format. • Field mock-ups test both the effectiveness and the constructability of details while establishing expectations regarding sequence, method and construction quality. Mock-ups may be constructed as stand-alone assemblies that are

• Laboratory testing is useful when very specific criteria are important to the success of a particular detail. Wind flow patterns, fire resistance, structural load testing, and resistance to accelerated weathering cycles are some examples where lab testing can improve the designer’s understanding of how the particular detail will perform. Now that we can visualize how our details may enhance design considerations, control the effects of weather and climate, and allow for continuity and constructability, close your eyes again and try to picture how you would currently conceive the details if you could revisit your previously completed projects. Next, imagine how these details can be developed and presented in a more descriptive modeled form, using the tools and methods at your disposal to overcome the traditional constraints imposed by time and budget. If you can now picture details in a sculptural, three-dimensional form, in your mind and on the sheets of your construction documents, as vividly as you picture the building itself then you have truly started seeing details■
