editor’s NOTEBOOK

Learning is changing As a former teacher (a long time ago) our lead article, “Build Schools For Today’s Learners,” p. 8, spoke to me on several fronts because it discusses a learning environment in which it would be great fun to teach. Now, as editor of a commercial-construction magazine, the article makes a clear and unavoidable statement about what is happening with classroom design.

It wasn’t too many years ago that we realized students didn’t do well if you forced them to spend entire days sitting in windowless caves with bad indoor air. Turns out that the fear that students would be distracted if they could look out windows was dead wrong, mainly because, much to our surprise, humans are not very closely related to bats.

But cutting holes in walls and filling them with glass is minor compared with what lies ahead. Technology is upsetting the school apple cart. This passage from the article really smacked me on the back of the head, “Why are we still specifying combo-desks lined up in rows facing a single wall of boards and a clock? Besides giving students a clear view of how much longer they have to sit and listen, this conventional design does not support 21st-century learning standards. Flexible, mobile furniture that students can configure into learning groups with easy access to multiple resource tools should be the norm in today’s learning spaces.”

Tablets, smart phones, computers, e-books, and other electronicsbased learning tools are rapidly making a dinosaur out of conventional classrooms and libraries. As funding becomes available, and it will because the demand will be intense, changes in school designs will quickly ramp up. The real challenge will be meeting today’s learning-environment needs by re-designing existing classrooms.

The assumption is that this change is only happening in big cities with large school districts. Not so. One example is West Elementary School in the small farmtown of Sycamore, IL. Teachers Katie Algrim and Jennifer McCormick (as reported by Jeff Engelhardt in The Daily Chronicle, DeKalb, IL, Jan. 31, 2012) have gone paperless and reconfigured their teaching tools and classrooms in favor of a collaborative, electronics-based approach and it’s working beyond their expectations. According to Algrim, “I’m meeting so many more of my students on an indvidual-need basis. They’re surpassing what we thought they could do.”

If schools are part of what you do and your mind is still thinking rows of desks and chairs facing a chalkboard, you need to toss your T square and pencil because your designs are no longer of interest.

Complete Wall Systems For Commercial Construction Herbert Slone, Owens Corning

C

enturies ago, building walls served a simple purpose. Constructed from heavy, load-bearing stone, walls served to repel the elements and protect occupants from the threat of fire, simply through their mass and thickness. The comfort they provided, in terms of temperature and moisture control, was limited, to say the least, and energy efficiency wasn’t even part of the discussion.

Today’s walls, with multiple materials that lack the permanence of stone, require thoughtful detailing to be durable and perform well. They have come a long way in construction techniques, materials, performance, efficiency, and in providing occupant comfort. However, with so many elements to consider, selecting the materials and components to be contained within these walls is not always an easy task.

To help simplify the process and meet the increasing performance and efficiency demands of this ever-competitive building market, some major manufacturers have introduced complete wall systems, which are designed to suit the unique needs of a wide variety of buildings while also providing outstanding energy efficiency and complete air- and water-barrier performance. They also offer fire, structural, and acoustical qualities.

Can you imagine working with one contact to source all of the materials that contribute to these qualities? Whether discussing the development of a new structure or retrofitting an existing building, complete wall systems resonate with architects and contractors for the efficiencies they provide, in energy and ease of specification.

Enhanced performance with systemization One of the biggest benefits of working with complete wall systems is the ability to provide a one-stop solution to minimize energy use and maximize resistance to water and air penetration.

Besides structural demands addressed by steel, masonry, concrete, or wood, there are several other key elements to consider when selecting a complete wall system that best fits a project.

Energy and thermal efficiency Energy efficiency (relating to national energy policy and the cost of energy associated with operating a building) and thermal efficiency (the level of efficiency relating to the building construction itself) are addressed with the use of complete wall systems. In fact, one of the most important components in a complete wall system is insulation. Beyond the immediate economic return of reduced energy costs, a well-insulated building envelope ensures a building meets na6

tional energy codes and policies and promotes its overall operating efficiency.

Whether in wood- or steel-stud framing, masonry cavity walls, interior furring, or as the core of concrete sandwich panels, a layer of continuous insulation, included in any complete wall system, thermally seals the exterior wall and minimizes thermal bridging through structural elements.

In addition to continuous insulation, additional insulation inside stud-framing cavities, including fiberglass batt or spray foam, provides a higher R-value, using that valuable space to better insulate the building envelope.

Insulation as investment The use of energy-saving insulation is not only a sustainable-design practice, it is also an economic investment. Putting aside the sustainable considerations for a moment, if energy was free and limitless in supply, then the motivation to invest in insulation would be very low. Of course, energy is neither free nor limitless in supply. So insulation is an investment. One buys insulation with the expectation of a return on that investment. But how much money should be invested in insulation?

What is the optimal amount?

Optimum insulation is the amount of insulation that has the lowest life-cycle cost. Lifecycle cost for insulation and energy is, in its most basic definition, the first cost of the insulation plus the cost of energy use associated with that amount of insulation.

Managing air, water, and vapor intrusion Managing air and water intrusion is important to any commercial or residential building product.

Water can enter through the walls in a number of ways, such as through open-joint designs in the rain-screen cladding, through surface absorption by brick or CMU veneer, through controlled flexural cracking, or even by construction defects.

Concerning rain-screen systems, the first defense against intruding water is a pressureequalized air space behind the cladding to allow water drainage. In systems such as these, where it is by design that water penetrates the rain screen, it is important to choose a highly water-resistant, continuous-insulation solution. Therefore, the second line of defense must be highly waterresistive extruded-polystyrene (XPS) sheathing with high-quality joint tape over the joints or other types of sheet or spray membranes, or XPS used as panel-core insulation in panelized construction.

Vapor protection, achieved by the use of a variety of fiberglass-batt insulation facer materials

available to suit all types of construction, is another added benefit of complete wall systems, protecting against disastrous vapor intrusion and potential condensation.

With these elements, buildings are protected by a continuous water- and air-resistive barrier layer, minimizing air infiltration/exfiltration and water intrusion. Improved air and water barriers also enhance the thermal performance and longevity of steel-stud wall assemblies.

Fire safety Along with energy efficiency and the reduced operating costs that complete wall systems provide, the materials used in these systems also aid in meeting building-code requirements. Fire tests such as ASTM E119, used to determine timed structural-fire resistance, and NFPA 285, which is used to limit potential fire spread by combustible insulation used on buildings that are otherwise a non-combustible construction type, can all be met through appropriate use of materials throughout the building process. Complete wall systems are designed with these requirements in mind and have been tested for complete assembly compliance while also guaranteeing that the combination of materials used within the wall offer long-term performance within the structure.

In the commercial-roofing industry, system suppliers that provide all of the components to construct roofs and then provide a single-source performance warranty upon completion have long been the norm. On the other hand, pieces and parts coming from multiple suppliers are typical in the commercial wall market. There is a clear demand to create a single-source, systemized approach to wall construction, similar to that already practiced in commercial roofing.

As the construction industry continues to move toward the systemization of walls and complete performance, it’s important that sustainability, durability, air and moisture management, fire test compliance, and optimum insulation are top of mind for every architect, contractor, and building owner. Complete wall systems provide solutions, addressing the needs of buildings for tomorrow, not just for today. Not only does a single-source approach streamline the process of choosing wall materials, but it also provides users with the comfort of knowing that these systemized materials have been proven to work with each other for optimum results.

T

he early 21st century is an exhilarating, yet demanding, time in education. Student learning is evolving from memorization and the passive transfer of information from teacher to students to collaboration, active learning, and mentoring, with a focus on problem solving, critical-thinking skills, and personalized instruction. Technology tools; social media; and the recognition that the dated, industriallearning model is leaving American students at an international disadvantage are changing our approach to learning.

A simple review of common core standards, or the American Association of School Librarians’ (Chicago) Learning 4 Life objectives, should quickly alert architects, facility planners, and school administrators that it is time to think out-of-the-box when planning or remodeling school buildings.

Planning a school must progress beyond the

“build it and they will come” mentality. The effects of open enrollment, failing schools, home schooling, and academy or charter schools demand that districts seriously evaluate their learning cultures, resources, and physical environments. Parents and students have choices now that were not available a few years ago. The funding from states and the federal government is tied to the number of students in a district and their quantitative progress. As a result, school districts have to ask if they are planning buildings that will support contemporary learning, attract families to their districts, and are environmentally responsible.

Leading with LEED Another important consideration is whether a school’s learning culture and environment attract the best teachers. Research clearly indi-

cates that quality teachers are the main ingredients of quality learning. If districts must increase class sizes, limit support staff, and ask teachers to contribute more to their benefit packages, what can they offer good teachers to secure their loyalty?

For most districts, the answer is to shoot for the same elements that attract parents and students: focus on planning and creating a unique environment; espouse a collaborative, dynamic learning culture; and provide the technology tools teachers need to facilitate their work.

Because unhealthy buildings have a dramatically negative impact on the performance of students and teachers, creating an effective learning environment starts with a commitment to LEED certification: • Plan a healthy, energy-efficient building with a lot of natural sunlight.

Support for collaborative learning

•

Wherever possible, foster a connection to nature.

• Conserve water.

• Make sure children and adults are breathing clean air.

• Bring in only the products and furnishings that complement those objectives.

• Understand the educational models and determine what room shapes and sizes best support those models.

For example, building 800-sq.-ft. classrooms off long corridors with rows of desks facing the front of the room is extremely shortsighted today. Building a structure without WiFi throughout the campus and ubiquitous access to power is inexcusable. Don’t assume students will check out laptops from a cart and recharge them in that cart in a specified location. Build an infrastructure that allows students to work in a flexible environment using

When learning can occur anywhere and collaboration happens spontaneously, the demands on space and furnishings to support that activity also must change. How they change and what options can be incorporated into an environment should be thought through and discussed in the planning stages. Establish clear learning goals and objectives, and then build a school to nurture those goals.

Learning commons are currently getting a lot of attention. They were first introduced on college campuses as a 24/7 environment that supports a broad array of technology and multimedia production, personal and group spaces, academic support, and flexible open space. The learning-commons concept is being emulated and integrated into K-12 buildings as open spaces adjacent to clusters of classrooms and as an alternative to a traditional library.

Though an interesting, experimental space in K-12 buildings, they are not funded, equipped, staffed, or available to students in the same manner as on college campuses, so the model frequently falls short in the K-12 environment where the above-mentioned issues and the lack of teacher training compromise the concept.

As a shared open space o outside classroom clusters, tthe areas compensate for classrooms with limited c flexibility. These commons ggive students a convenient llocation to collaborate, work on projects, or break w iinto smaller self-directed ggroups.

feature EDUCATION itself to a single librarian managing the space.

Collaboration between all teachers in a building, including the librarian, is mandatory. Curriculum has to be developed to leverage resources and the space must be large enough to allow multiple classes and individuals to use it simultaneously.

Not a book warehouse Too many new or renovated libraries are simply the old model but smaller, a shrinking warehouse for books, a mausoleum to the beauty of wood, the culture of paper with enough lounge seating to channel a Borders bookstore. There are some variations being explored that usually start with a traditional library, some rows of shelving, a large circulation desk, tables and chairs, and token soft seating. Next to this wooden, inflexible space, always separated by a glass wall and doors, is a technology lab with multi-media production capability. “The library and the lab” are close enough to see each other but live separately. Why? These two spaces must be blended to allow fluid access to all resources by students.

Another library model spreads resources throughout a building or around a campus based on areas of focus. Frequently, these satellite libraries evolve around a home base where content is managed. This model demands a

mobile librarian who does not get distracted by the management of content rather than student learning at the satellites. Even so, access to a librarian at the satellites is limited so students have to be self reliant and fairly skilled as independent learners or the concept is counterproductive.

The original concept of a school library housing a vast array of resources shared by all students is still a logical and sustainable solution for most schools. It is a prudent use of funding and staffing but it needs to mature and re-invigorate itself. How the space operates, what the resources will be, who the mentors must be, how the space will incorporate personal tools, and how students will learn and leverage the space is still on the drawing board. Additional concepts for moving resources closer to the students should be explored. And how students will create new knowledge and share it should also be examined. New models need to emerge with a focus on user-based designs.

YouMedia, the teen space at the Chicago Public Library, is an interesting early model that schools should investigate. Funded by the MacArthur Foundation, Chicago, it mixes print and media, allows ample space for creativity, is flexible for either group or individual work, contains instructional space along with gallery

space to share work, and has a strong philosophy of mentoring students. Unfortunately, the answer to keeping the furniture flexible or mobile literally entails “tails,” or long power cords, on most of the tables. But from a positive point of view, the library does give physical form to the extensive research documented in the book “Hanging Out, Messing Around, and Geeking Out: Kids Living and Learning with New Media,” The MIT Press, 2009.

Today there is an exciting opportunity to invent healthy, fresh learning spaces based on 21st-century learning models. Planning and talking through learning objectives and desired outcomes should lead to unique, new learning environments for students.

Making Post-9/11 High Rises Safer From Fire

A NIST investigation generated 30 recommendations for improving fire safety in tall buildings. Photo: Gary L. Parr

Fire-protection practices and technologies for tall buildings influence design and construction.

Chris Jelenewicz, P.E., Society of Fire Protection Engineers

S

eptember 2011 marked the tenth anniversary of the terrorist attacks that led to the collapse of New York City’s World Trade Center towers. The disaster changed how the construction industry builds tall buildings.

Immediately after 9/11, the fire-protection community turned its attention to finding ways to build safer tall buildings and reduce vulnerability from such incidents. Although better buildingdesign methods and codes cannot stop determined terrorists, they can dramatically reduce the number of fatalities in the event of an attack.

In response to the World Trade Center tragedy, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST), Gaithersburg, MD, investigated the factors that contributed to the collapse of the structures. According to NIST, the goals of the investigation were to consider the buildings’ construction, materials used, and technical conditions that contributed to the outcome and to serve as the basis for future planning: • improvements in the way buildings are designed, constructed, maintained, and used • better evaluation tools and guidance for industry and safety officials • recommended revisions to current codes, standards, and practices • increased public safety.

feature LIFE SAFETY recommendations divided into eight groups listed below, all designed to improve the safety of tall buildings.

Increased structural integrity.

NIST recommended that the standards for estimating load effects of potential hazards such as progressive collapse and wind loads be improved to enhance structural integrity. One of these recommendations suggested that primary structural systems provide alternate paths for carrying loads so that important structural components remain intact, significantly Additional architect and engineer training was recommended in the areas of structural fire protection and fireprotection engineering.

reducing the risk of a progressive collapse in tall buildings. Additionally, the report suggested that the wind loads identified in the prescriptive codes might not be appropriate in tall buildings.

Consequently, it recommended development of performance-based standards to estimate wind loads and their effect on tall buildings.

Enhance fire resistance of structures.

NIST recommended procedures and practices to improve fire endurance. Specifically, building codes should provide a means to better distinguish the impacts of building height, building fuel loads, and fire-protection systems on the fire resistance of a structure. The report also recommended improved testing methods for materials used for structural fireproofing.

New methods for fire resistance of structures. Before 9/11, building codes did not mandate performance-based standards that addressed how uncontrollable fires that lead to 12

burnout could cause a structure to collapse, so the report recommended that the building codes provide performance-based standards to address this issue. It also recommended that these same performance-based standards examine how failure of a fire-protection system would affect the building structure. Other recommendations related to the installation of structural fireproofing are now provided in the building codes.

Active fire protection. This section of the NIST report focused on improving the performance and redundancy of fire-protection systems, such as automatic fire sprinklers, standpipes, and fire-alarm and smokemanagement systems. The recommendations suggested improvements in fire-protectionsystem design and installation in buildings that have higher risks, such as tall buildings, and buildings with large open spaces, large populations, and transient fuel loads. It also called on the design of fire-alarm systems to include communication systems that can withstand fire conditions and provide more accurate information during building emergencies. Another recommendation related to a building’s fire-alarm system providing better information to emergency responders.

Improved building evacuation.

More-efficient building evacuations formed another cornerstone of the NIST report.

Recommendations included ensuring safer and more rapid evacuations, along with providing a way to help occupants be better prepared for emergencies. One of the recommendations suggested that tall buildings be designed to accommodate timely, full-scale building evacuations during emergencies such as fire, terrorist attacks, earthquakes, hurricanes, explosions, and tornados. Other recommendations related to protecting elevator enclosures and exit stairs, marking exits, and providing adequate means of escape for persons with disabilities.

Improved emergency response.

The NIST report suggested enhancements to buildings to better support fire-department operations during emergencies. One of the recommendations focused on providing structurally hardened elevators to improve reliability for use by the fire department. There were also recommendations related to improving fire-department emergency-communication systems and the responder command structure.

Education and training. Additional training was recommended for architects and engineers in the topics of structuralfire protection and the principles of fireprotection engineering. It is essential for design professionals to understand the basic principles of fire-safety design. Another recommendation related to providing additional training for the

fire service in topics related to building-design reviews and inspection procedures.

Improved procedures and practices.

The report offered several recommendations related to improving procedures for the design, construction, maintenance, and inspections of buildings, including recommendations that jurisdictions implement existing provisions in building and life-safety standards for egress and installation of automatic fire-sprinkler systems.

Another recommendation suggested maintaining design/as-built documents over the lifespan of a building.

Working with the pros Moreover, NIST recommended including fireprotection engineers (FPEs) in building-design teams to aid in planning to prevent future devastation, especially in high-risk structures such as tall buildings. Fire-protection engineers understand the science and technology required to make buildings safe from fire and can make invaluable contributions to a design team. An FPE can coordinate the fire- and life-safety aspects of the design disciplines (architectural, structural, civil, mechanical, and electrical), focus the design team’s attention on solving related issues, and save time and expense. A fire-protection engineer can: • help develop goals with an understanding that designs are intended to limit the threat to lifesafety for the public and emergency responders and to reduce potential property loss • interpret a variety of applicable codes and standards with an understanding of how a building and its components function as an integrated fire- and life-safety system, which enables the FPE to recommend cost-effective solutions that provide fire safety to the overall design • focus specifically on scientific and engineering methods for fire- and life-safety analysis and design, whereas engineers from other disciplines focus on other building systems and features.

Methods can include computer modeling, such as computational fluid dynamics and humanbehavior modeling.

• produce a set of fire-protection design documents that anticipate the details of a fire-protection installation, based on an integrated-systems approach that can yield tighter construction-bid prices • recommend corrective actions that can minimize change orders and associated cost increases if a problem is discovered during construction • develop a plan to commission and accept fireand life-safety systems.

Thinking through the unthinkable The fire-protection community has worked hard to implement the recommendations from the NIST report into the model building and

fire codes. Because tall buildings have unique features that make it more challenging to create designs that keep people safe during emergencies, it is imperative for the design and construction industries to understand how new fire-protection practices and technologies have changed as a result of 9/11. Some of these changes are related to: Facilitating more-efficient building evacuations. Buildings more than 420 feet tall will have an additional exit stairway, and exit stairs will be required to be wider to provide faster occupant evacuations. The changes also will make it easier for emergency responders to advance up stairs during emergencies.

Additionally, elevators may be used for evacuations during emergencies when the elevators comply with special protection for wiring and cables, emergency power, and protection from fire-sprinkler-water discharge.

Other requirements relate to elevator monitoring systems, building-wide voice/fire alarm systems, signage, and the size of elevator lobbies.

Improved marking of exits. For buildings more than 75 feet tall, new requirements call for increasing the use of luminous marking systems to identify exit paths, exit doors, and exit signs for occupants trying to evacuate a building.

Luminous marking systems do not require an external energy source, electrical wiring, or batteries.

Protecting the integrity of stair and elevator enclosures. Stair and elevator enclosures will be hardened in buildings more than 420 feet tall, as well as in essential buildings, such as hospitals, between 75 feet and 420 feet in height where failure of the enclosure would substantially jeopardize life. Hardened enclosures are designed to withstand substantial physical impacts.

Specifically, enclosures constructed of masonry, concrete, or wall assemblies that pass the ASTM C1629/C1629M-06(2011) Standard Classification for Abuse-Resistant Nondecorated Interior Gypsum Panel Products and Fiber-Reinforced Cement Panels can be classified as hardened.

Remoteness requirements for exit stairways ensure that if one stair is blocked, there is greater probability that the other stairs are not blocked.

To be considered remote, exit stairs are now required to be separated by a distance of 30 feet or not less than a fourth of the maximum building diagonal, whichever is less.

Increasing reliability of sprinkler systems. Although fire sprinklers are very reliable systems, steps have been taken to increase their reliability in buildings taller than 420 feet. For example, each fire-sprinkler zone in such buildings will now be supplied by two water-supply risers. Each riser must be remotely

located in protected stair enclosures.

Improving the installation of structural fireproofing. Provisions have been made to ensure fireproofing will resist abrasion and adhere to the substrate material under deflection. For example, the bond strength of structural fireproofing materials will be required to be 1,000 psf for buildings taller than 420 feet and 430 psf for buildings between 75 and 420 feet. The bond-strength requirement is for all structural fireproofing in a building. Other installation requirements for structural fireproofing ensure that the installation complies with the manufacturer’s requirements, surfaces being protected are clean, adequate testing is provided to demonstrate adhesion is maintained, and fireproofing is not affected by building systems such as mechanical, electrical, plumbing, and fire-protection systems.

Facilitating improved emergencyresponder operations. There have been many advances in assisting emergency responders during emergencies. For example, buildings taller than 120 feet will now have at least two fire-service elevators. Additionally, fire command centers will be larger so that command staff will have more room to effectively administrate the

emergency response. Other new provisions for emergency-responder communication systems ensure responder radio coverage throughout a building.

These are just some of the important life-safety features that will be provided in tall buildings in the future. It is important to note that these requirements have been established in the model codes and standards. When designing and constructing a building, check with the specific jurisdiction’s building- and fire-code requirements and coordinate the requirements with the project’s fire-protection engineer.

While it is impossible to construct a building that is immune to every type of disaster, the lessons learned from 9/11 will help keep buildings and their occupants safer than ever before.

elf-help guru Steven Covey offers some very important advice that is applicable to the world of architecture. In his 1989 book, “Seven Habits of Highly Effective People,” he suggests that you begin with the end in mind. This concept is useful in many aspects of construction, but its significance becomes evident when applying it to design principles for controlling the energy flow through a building, known as indoor environmental ergonomics.

The term indoor environmental ergonomics might be new to most, but it falls under the practice of indoor-climate engineering. It implies something much deeper than traditional knowledge of HVAC, which is associated with the needs of a building. Indoor environmental ergonomics is associated with the needs of a building’s occupants.

The primary message of indoor environmental ergonomics is that if we begin with occupant needs underpinned by the unadulterated definition of sustainability, using indoor-climate engineering to establish indoor

environmental quality, the end game will result in a high-performance building. Even though this approach has immense benefits for contractors, designers, and consumers alike, it is not a trivial undertaking. It involves the busting up of egos and tradition.

Comfort and efficiency By ethical requirements, professionals must agree buildings at least should limit the probability of occupants becoming OSHA statistics as a result of the poor quality of air, lighting, sound, odor, vibration, and thermal comfort. The combined building, mechanical, and electrical systems should meet or exceed any efficiency standards that are mandatory at the time of construction. If the architect and the client have an obligation to the principles of earth stewardship, the principles of efficacy, entropy, and exergy must be included alongside the evaluation of energy efficiency.

To accomplish this evaluation process, one must remove some obstacles, such as

feature HVAC the industry practice that treats architecture, interior design, HVAC, and lighting systems as separate items. From the perspective of energy and building occupants, these elements are integrated. For example, with thermal comfort an occupant’s brain is like a blender, except it identifies the individual ingredients: “Nice view, but I’m freezing.” The same process applies to IAQ, although the brain can’t always identify the ingredients: “Nice flooring. Is anyone else in here getting headaches?”

In solving these problems, there will always be a corresponding flow of corrective energy: I’m cold = turn up thermostat = turn on burner/ pump/fan = consumption of fuel and electricity = an act of treason against sustainability goals.

In keeping the end in mind, the goal is not to condition a building but to condition the occupants to treat an HVAC concern, in the most sustainable way. The equipment remains off, conserving energy.

This principle applies to other conscious and subconscious responses found within the human body. For example, responses to the indoor environment can include itching, sweating, congestion, runny nose, sneezing, shivering, squinting, headaches, rashes, or hives. Corresponding adaptive strategies are scratching, turning on a fan, pinching one’s nostrils, blowing one’s nose, putting on a sweater, closing the blinds, opening a window, and taking medication.

A building in part contributes to these conscious and subconscious reactions. The qualitative and quantitative magnitude is proportional to the quality of the ergonomics of the indoor environment. In layman’s terms, the more one is distracted by responses to one’s environment, the less one is focusing on learning or being productive. According to published research, this distraction or downtime expressed as a dollar cost over a few decades far exceeds the capital and operating costs of the building itself. This is true even in the presence of all that new, zippy, high-efficiency equipment. Smart, zippy equipment does not equal smarter, zippier occupants!

It is evident that indoor ergonomic quality (IEQ) and energy challenges could be simultaneously solved, at least partly, if the architecture were based on all human factors— except those stimulated by esthetics. There are no OSHA statistics attributable to ugly buildings and ugly interiors. Even the most visually appealing architecture cannot compensate for the negative effects of a bad environment (“Nice building, but can you feel that draft?”) and in almost all cases, bad environments are the contributing factor to the excessive use of nonrenewable energy. (“Nice building, but it’s still drafty. Turn the heat up more.”)

Turning comfort inside out Using thermal comfort as a surrogate for other sensory examples, let’s look at how an inside-out approach to design trumps the current outside-in approach.

The human body already has its own energy-management and environmental-control systems. As close to perfect as these systems are, they are no matches for Mother Nature in all but the most temperate climates. Fortunately we don’t need to construct buildings to entirely replace our physiological and psychological systems, only to compensate for some of their shortcomings.

The solution is a combination of passive/ adaptive and active systems. The former incorporates solar, wind, building orientation, shading, and enclosure performance, along with adjustments to activity and clothing. The latter uses active elements measured in the flow of non-renewable energy through the building for operating HVAC equipment and lighting.

Due to our common human physiology, the quantitative value used for conditioning people is remarkably similar, regardless of culture. In the

In keeping the end in mind, the goal is not to condition a building but to condition the occupants to treat an HVAC concern, in the most sustainable way. absence of visual stimulation, people from all over the world would choose materials and methods of construction having a similarly agreeable effect on their thermal, respiratory, auditory, olfactory, and kinesthetic senses—but not on vision. Visual stimulation is the stressor that challenges us in making sustainability-based decisions. Decisions based on visually appealing but unsustainable factors lead to architecture that compromises our comfort—“Great view, but it’s too bright and too hot. Please close the blinds and turn on the a/c.” Senses that are compromised lead to less productivity or learning, ergo the inside-out approach (occupants before architecture) trumps the outside-in (architecture before occupants) approach.

establishing minimum requirements as benchmarks. By educational standards, however, minimum requirements earn a D grade. When D-grade thinking is adopted en masse, as it has been in North America, it becomes maximum practice in a field wherein a representative code clause, such as “heating facilities shall be capable of maintaining an indoor-air temperature of not less than 71.6 F,” has become the benchmark for establishing thermal comfort.

What adopters of D-grade thinking fail to realize—or deliberately ignore—is that the D-grade minimum in climate engineering is in fact a downgrade from the requirements of the human body as recorded in written standards (ASHRAE 55/ISO 7730), which are based on health-science research. D-grade thinking is one of several reasons why 30% to 50% of the population is dissatisfied with their indoor environments, and that later shows up in lower academic scores, lower productivity, and suppressed general happiness.

Furthermore, the lower price of a D-grade system (disguised under the term affordable) only moves the project closer to the grade of F. Grade F happens because people didn’t want to pay for grade D. Why is that F is so easy to get in the first place? Because the minimum benchmark is set too low—below the standards.

As an example, in the world of indoorclimate engineering, measuring thermal comfort exclusively by air temperature is so inadequate there should be little blue pills for it. Endorsement and enforcement of 72 F air temperatures by industry has resulted in an inventory of buildings that have tried to solve thermal-performance problems by unnecessarily creating 2,800 F flame temperatures in furnaces for the exclusive purpose of excessively heating the air rather than solving the underlying thermal-comfort problem, which is not rooted in air temperature but in the mean radiant temperature (MRT)—an element intimately tied into the enclosure performance and the body’s thermal-sensory system.

We don’t inhale comfort. We sense it through our skin, which is an almost perfect absorber and emitter of radiant energy. Air-only thermostats are and always will be poor thermal ambassadors for communicating human thermal needs to any mechanical system.

Enclosures and comfort The best way to point out the narrow-sighted focus on air temperature is to draw attention to comfort standards, among which air temperature is only one of ten elements considered by indoor-climate engineers (see Table 1.) With the exception of metabolic rates, clothing, air speed, and humidity, all elements are a function of enclosure performance. Of special interest

feature HVAC to thermal-comfort technicians are the interior surface temperatures, which are a derivative of the combined performance of the fenestration systems, insulation values in the opaque surfaces, and building tightness.

To engage the power and simplicity of the relationship among enclosure performance, radiant transfer, and thermal comfort, the status quo must go from architect and client telling the HVAC engineer, “Here are our blueprints. Now design your system to make our building work,” to the indoor-climate and energy engineer saying to the architect and client, “Here are our systems to meet energy budgets and IEQ standards. Now design and build an enclosure to make them work.” In this wonderfully disruptive, in-your-face, inverted approach, mechanical- and electrical-design teams see architecture and interior design as a means of enabling maximum performance from the mechanical and electrical systems for the exclusive purpose of conditioning occupants instead of a building.

Here’s where we connect the various dots: The most efficient system possible, based on the principles of combustion and compression efficiency, must be based on the lowest return temperatures for heating and the highest return temperatures for cooling. The only way to achieve the lowest and highest temperatures for heating and cooling, respectively, is to precede the architectural design by specifying enclosure performance by way of thermal fluxes (see Table 2) and then to incorporate large, conductive, low-VOC interior-surface areas (walls, floors, and ceilings) as heat exchangers.

Why use interior surfaces as on-site, fabricated heat exchangers? Indoor-climate engineers know that if the environmental ergonomics influenced by warm and cool surfaces can suppress or encourage body-heat loss based on the radiant exchange, they can efficiently address almost all of the parameters required to meet thermal-comfort and energy restrictions.

The control of the radiant exchange between occupants and the building trumps control over air temperature. The control is established first with enclosure performance and then augmented with a radiant-cooling and -heating system that uses a dedicated outdoor-air system for deodorization, decontamination, and dehumidification in a radiant-based HVAC system. (See Table 3 for nominal requirements for various heating and cooling fluxes using low-VOC, conductive floors, and tight tube spacings. These are based on typical space temperatures of approximately 72 F for heating and approximately 78 F for cooling.)

Efficiency for all seasons Equipment manufacturers, related mechanical contractors, and designers should recognize the 18

potential efficiencies in condensing boilers, heat pumps, and chillers with some of the parameters above. Using traditional differential temperatures, for example a 20 F in heating for a high-performance building, i.e., terrific enclosure, supply temperatures become 78 F + (20 F/2) = 88 F. Return fluids become 78 F – (20 F/2) = 68 F. At such low return temperatures, the combustion efficiency climbs into a high 90% range. With the use of weather compensators, this type of efficiency can be maintained throughout the entire heating season. Likewise, one can see the efficiency destruction when the buildings are inefficient, particularly in the cooling modes. Beyond the transitional building in cooling, radiant surfaces are useful as a base system, engaging supplemental systems during peak loads.

If we begin with human-factor design underpinned by the unadulterated definition of sustainability, using indoor-climate engineering to establish indoor environmental quality, the end game naturally will deliver highperformance buildings.

When designers can focus on controlling occupant heat transfer to and from interior surfaces using enclosure performance, the result is warmer interior surfaces in winter and cooler

interior surfaces in summer. Such passively controlled surface temperatures—and the use of low-VOC finishes—improve the health of an environment while reducing the operating time of active systems, a key component in sustainability.

When heating and cooling equipment must run during swings in extreme seasonal loads, it must run at maximum efficiency enabled by the low heating temperatures and high cooling temperatures associated with radiant-based HVAC systems. The beauty of these systems is how well they play with natural materials and the multiple sources of renewable energy found in the earth, wind, water, and sun.

BACKUP POWER HVAC SYSTEMS

BUILDINGG POWER

F E AT U R E

A key decision to make when specifying backup-power systems is whether to use a single genset or a modular system.

Specify Backup Power That Fits Factors such as scalability, fuel sources, owner maintenance capabilities, and AHJ requirements determine whether a backup-power system will meet current and future needs.

Michael Kirchner, Generac Power Systems

P

eace of mind is a priceless and coveted commodity in today’s business environment. Adequate backup power contributes to that peace of mind, because down time means lost revenue.

However, specifying a backup-power system that is appropriate to a particular application requires attention to several details.

The first thing to consider when specifying a backup-power system should be obvious: power demand—the amount of electricity needed to back up all necessary circuits. However, what’s often not so obvious are the future power needs for the application. Over time, the power demands of a building—or the tenants in that building, if applicable—will likely change. The demands won’t get smaller, either. According to a commentary by Max Schultz on Forbes.

com (http://www.forbes.com/2009/06/04/americapower-grid-opinions-contributors-energy.html), the U.S. economy will require 30% more electricity by 2030. Increased power needs place more demand on a backup-power system in emergency situations, and can reach a point where the system can no longer supply the necessary amount of power. Additionally, because backup-power systems have an effective life of several decades, it’s important to build some scalability into the system so as not to replace a perfectly good—not to mention costly—backup-power system before it’s effective life has been exhausted.

Scalability can be addressed in a single-generator solution by simply designing extra capacity into the specification to allow for future power needs. This approach, while often acceptable, has its drawbacks. First,

Get free product information at www.cbpmagazine.com

it requires an accurate estimate of what the maximum power needs of an application will be over the course of the generator’s life. It also ties up capital in the backuppower system at the outset—monies that might be better invested elsewhere. Additionally, because large generators use equally large engines that are manufactured in relatively small volumes, turnaround time for such a system can be longer than anticipated, which can cause problems from a project-scheduling standpoint.

An excellent alternative to this approach is a modular power system, in which several smaller generators are connected in parallel to provide the necessary output. Such systems are becoming increasingly cost effective and space efficient, thanks to new digital technologies that control all generator functions and switchgear integrated into the generators themselves.

As the power needs for the application grow, additional generators can be easily added to the system to provide additional capacity. This allows a less-accurate initial estimate of how power needs will grow, because additional capacity can be added in relatively small increments.

A modular system also offers installation flexibility not found in a single-generator (genset) solution, because the units need not be installed side by side. Additionally, because these smaller generators typically use high-volume, on-highway truck- and automotive-derivative engines, instead of the lowervolume large engines mentioned earlier, most manufacturers can fulfi ll modular power-system generator orders in a shorter time. That means additional capacity can be added very quickly to a system to accommodate growth.

Build in reliability Reliability is also a key factor in specifying a backuppower system. Nothing is worse than expecting a backup-power system to protect your investment, only to have it fail when it’s needed most. While on the surface, reliability sounds subjective—related exclusively to one’s belief in a brand name or faith in a particular system’s components—there are some concrete ways to evaluate reliability in a backup-power system.

Consider the single-engine vs. modular-power system example described above. Large single-engine gensets can offer reliability on the order of 98% to 99%, which is perfectly acceptable in many applications. However, there are those applications, such as mission-critical data, where a power failure means a business failure—not just a loss of revenue. In such cases, maximizing reliability should be the goal.

Modular power systems can do that, as well, through increased redundancy. Unlike a single-generator solution, no one generator failure results in the failure of the entire backup-power system. As previously mentioned, if the reliability of a standby generator is defined at 98%, a modular power system, with an N + 1 configuration, has a reliability of 99.96% and an N + 2 configuration has a reliability of five nines. Thus, when the power absolutely, positively must remain on, it might be wise to eschew a single-generator solution in favor of a modular power system.

Another reliability factor is the fuel supply. Diesel fuel has been the traditional choice for backup power because its high thermal efficiency typically results in a lower cost/kilowatt in larger applications. Additionally, emergency system on-site fuel storage tends to be preferred by many authority-having-jurisdiction (AHJ) agencies. However, issues of fuel storage, contamination, and breakdown can have an impact on system reliability. If ongoing fuel maintenance will be a challenge for a given customer, a diesel-fueled genset might not be the best choice.

Natural gas is being considered more often for standby applications because it avoids the diesel-fuel storage issues. The natural-gas infrastructure is generally not affected by utility failures. However, the natural-gas supply can be affected in situations such as seismic ac-

he Salvation Army opened its new childcare development center in Oak Park (Sacramento, CA) in June 2011. The Alhambra Day Care Center, a $3 million, 14,000-sq.-ft. facility, replaced a 2,400-sq.-ft. modular building that housed The Salvation Army daycare center for the past 24 years. As part of the exterior design, the architecture team chose a brick exterior to coordinate with the nearby community center’s brick building.

In addition to the brick, the architect’s early design concepts for the new child-development center called for concrete columns and metal ceiling panels for the large entry canopy, soffit, and fascia. The problem was that the specified concrete columns were expensive and the metal-canopy soffit added another building material, which was undesirable. The search for alternatives succeeded when MEG exterior panels, manufactured by Abet Laminati, Englewood, NJ, were chosen.

“MEG exterior panels were specifically selected to emphasize the entry of the building and its columns and canopied roof and introduce a material that was independent of all other campus building materials,” explained Mike Buschow, principal, GRA-Architecture, Sacramento, CA. “The MEG exterior panels allowed for economical light-gauge metal-column framing and material consistency between column, roof canopy, and fascia. The MEG panels’ exposed reveals also tied in with the curtain-window walls’ linear design expression. The panels’ water-resistant backing and membrane-applied, water-repellent substrate replaced the need for unsightly metal flashing details at the building’s entry,” explained Buschow.

Another solution the exterior laminate

project WALL SYSTEMS panels provided was strength. The design team wanted to use a material that would offer durability and weather resistance to the strong southern exposure while incorporating a material that clearly identified the building’s entry. The silver color of the MEG exterior panels was selected to provide a welcoming reflectivity of sunlight without the blinding effects associated with metal-panel finishes. The panels were cut in the field, and installation was relatively easy. “We were pleased with the finished product. The panels provided an articulate, precise finish with clean and crisp exposed edges and the use of exposed fasteners and complementary color,” Buschow added.

radius corner trim, were specified. On the upper and lower floor corridors, the panel heights were reduced to 4 ft. and included a cherrywood cap rail with a radius edge. Abet’s interior wall system panels typically are 10-ft. tall.

Interior solutions Abet products also solved an interior-design issue. The design team wanted to incorporate a wall product that would complement the rich interior colors but also provide durability and impact resistance from the high volume of daily use by children and parents. Abet Laminati’s interior wall system solved the problem.

The woodgrain implementation added a formality to the main central space, to which parents could relate, while the use of bold/ primary colors captured the interest and imagination of the children.

“We chose the Abet interior wall system over a plastic-laminate, glueapplied system for ease of installation and higher-end trim options that connected the buildings’ interior with exterior material selections,” stated Buschow. “Going with an interior plastic laminate over gypsum board requires a glued application, butt joints, and aluminum top and bottom trim. Abet provided greater reveal options and corner trims as a part of their system, which provides a higher quality of finish. The interior panels’ selected trim reveals were aligned with the exterior curtainwall horizontal window frames and column reveals, which presented a visual sight line of materials that connected from the exterior of the building into the interior.”

reasure Island Resort Hotel and Casino is one of the best-known destinations for the nearly 37 million people who annually visit Las Vegas. With 3,000 guest rooms, 90,000 sq. ft. of premium casino space, and nightly pirate battles and fireworks, Treasure Island attracts thousands of people every year, testing the durability of the hotel and everything within it.

When the resort recently underwent a $100-million renovation, DiamondGuard glass from Guardian Industries, Greer, SC, was installed on the front doors. Glass is a remarkably stable material, able to withstand most environmental stresses indefinitely.

However, the surface of regular glass is relatively easy to damage through mechanical contact with hard materials, resulting in visible cosmetic blemishes. Thanks to a proprietary coating applied with patented technology, though, DiamondGuard resists scratching from contact with keys, bracelets, purses, and other everyday items.

No fragile glass N S Since transparency is one of the primary sello iing points of glass, its rresistance to marring, sscratching, or corrosion directly influences its value. â&#x20AC;&#x153;We are seeing more demand for glass that can withstand the wear and tear of heavy use,â&#x20AC;? said Diane Turnwall, director of interiors for Guardian Industries.

Historically, efforts to protect glass have relied on organic surface treatments or films that lower its coefficient of friction or yield under impact. Another approach has been the use of inorganic oxide or nitride coatings to produce a hard surface layer. The drawback of the organic treatments is that they wear off, while the inorganic coatings are easily marred due to inherently high friction.

Permanently bonded to glass during the manufacturing process, DiamondGuard is a durable, protective coating that provides glass with exceptional scratch resistance. In fact, glass with DiamondGuard is proven to be more than 10 times more scratch-resistant

Easy to clean and tough “The next big thing in decorative glass is a technology that addresses the biggest reasons that owners are reluctant to use glass: scratching and ease in cleaning,” said Turnwall. “DiamondGuard glass provides the solution to these common challenges. Its scratch-resistant properties make the glass more forgiving to surface scratches. It also is easy to clean, usually requiring nothing more than water and a soft cloth.” She added that the coating can be further enhanced by decorative processes including mirrors, back painting, and silk-screening.

The same technology is used for mirrors.

cience and architecture have a long history of shared ideas, innovation, and creativity. Both academic disciplines use rational thought and inventive thinking to modify our surroundings. In many aspects, the two fields of study have shared origins and history. These commonalities can be seen in the design of the Marcus Nanotechnology Center on the campus of the Georgia Institute of Technology (Georgia Tech) in Atlanta.

The center was built to house advanced nanotechnology research in the fields of healthcare, renewable energy, and personal technology. The architectural concept behind the building was to have a state-of-the-art research facility designed to reflect the groundbreaking research being conducted inside, without impinging on the considerable aesthetic charm and lush landscaping of the campus.

Architects John Bush of the M+W Group, Chicago, and David Murray of Bohlin Cywinski Jackson, Philadelphia, spearheaded design efforts for what would eventually become known as the Marcus Nanotechnology Research Center Building.

Aside from a few requirements from the university, they had quite a bit of leeway for

the project. “We were able to develop different scenarios and designs as we saw fit,” said Bush.

Out of the box The designers had what amounted to a 190,000-sq.-ft. box and two design issues that required out-of-the-box thinking. First, there was no natural front or back to the building. With roads on three sides, the structure looked rather indistinct and not at all the aesthetic focal point the administration had envisioned. Second, the open design and surroundings of the building left it exposed to direct sunlight, resulting in cooling and energy-efficiency issues that were inconsistent with super-high-tech research being done inside the building.

The architects proposed building a 22,000-sq.-ft. perforated copper-panel screen wall to enclose the central mass of the clean room and the peripheral support areas. The copper wall would decrease the amount of heat coming from the south side of the building, lower the air-conditioning and heating costs, and add shape and dimension to the facility. The screen wall also would serve as a design point around which the architects would shape the rest of the building.

Builders added attachments to the

The architects chose copper for its architectural and sustainable properties. The material selected needed to be able to withstand all weather conditions. Copper is not only durable and long lasting, but it also has a high level of corrosion resistance. When exposed to the elements, copper develops a natural blue-green patina that serves as a protective shell.

An important consideration in choosing a material for the wall was ease of fabrication.

Copper’s malleability and durability are why it has been a popular choice among architects for centuries. Copper does not have the negative environmental impact of many other metals; its use in the design decreased the carbon footprint of the building.

“Using copper in architectural designs is a sound environmental choice because of its recyclability and long service life,” said Andy Kireta Jr., vice president of building and construction for the Copper Development Association (CDA), New York. “It is because of these qualities that you can still find copper roofs on buildings that date back many centuries.”

Finally, the design team chose to use copper because they felt it would fit in well with the surrounding landscape, which consists of buildings scattered among wooded areas and rolling lawns. Made from a metal with a natural, warm tone, the screen fits in well with its surroundings.

The panels allow light to filter through while blocking much of the sun’s heat and cutting solar heat gain.

meant coming in slightly over budget. Another key to the project’s success was the school’s dedication to fostering a design that would complement the purpose of the building and its surroundings.

In turn, the CDA and the Canadian Copper Brass Development Association, North York, Ontario, credited the Marcus Nanotechnology Research Center as one of 12 buildings to receive a North American Copper in Architecture award.

structure’s framework, so that the screen could be designed and constructed separately and attached to the building later.

The screen was manufactured by LinEl Signature, which designs, engineers, and manufactures architectural products in Mooresville, IN. LinEl purchased copper sheets from a U.S. copper fabricator, cut them to size, and shipped them to a subcontractor that punched them with circular holes in a specific pattern.

The company then formed the perforated sheets into raised panels of various sizes, providing visual appeal and meeting the architect’s aesthetic intent.

project HVAC An energy performance contract at UNCW guarantees an annual savings of $336,566, with a 2.7% annual escalation in savings.

Partnership Greens Energy And Operational Savings Performance contract helps a university meet mandated energyefficiency goals.

I

n 2006, North Carolina state facilities received a deadline from the state legislature: By January 2015, all state facilities, including state universities, must reduce energy consumption by 30% from a 2003 baseline. While turning off lights and adjusting thermostats would be helpful, facilities would have to make much larger changes to reach the goal. Efficiency upgrades had to become a number-one priority for facility administrators across the system.

Funding for capital-improvement projects was already tight. High-profile projects, such as a new facility, were still getting the green light, especially if there was a private-funding partner.

Unfortunately, boilers, chillers, light fixtures, and environmental-control systems are not as exciting to trustees and the public. As the economy shifted and state revenue streams began to dry up, finding a way to fund mechanical upgrades quickly became a concern.

The Univ. of North Carolina at Wilmington (UNCW) faced this very issue and turned to Brady Energy Services, Greensboro, NC, for a solution. Brady has a 50-year history of providing building and energy solutions for commercial and institutional facilities through its four offices and six parts stores across the state. The company’s comprehensive-solutions approach to facility upgrades results in dramatic energy savings and significant indoor-environmentalquality improvements.

Finding funding “The biggest hurdle for any improvement project is funding,” said Tim Gasper, PE, solutions engineer at Brady. “It can be even more cumbersome for state and local government projects, especially if there is a need for a bond issue or other public financing to raise capital for comprehensive retrofits.”

Many educational institutions have had success with performance contracts (PCs). By leveraging operational-expense reductions, lending institutions look favorably on the netzero effect on balance sheets by providing lowinterest municipal financing for these projects. In addition, a PC typically includes an investmentgrade cosigner to provide an extra layer of security for the guaranteed savings.

Performance contracts hold the provider responsible for the systems and equipment meeting annual performance guarantees or the provider must reimburse the institution for the difference, which lowers the risk for lenders.

PCs are not a new concept, but they are gaining

momentum similar to the growth of publicprivate partnerships in funding government projects. In 2006, the state approved the use of PCs by North Carolina agencies, including universities and community colleges.

Finding savings Technology is much more efficient today than it was 10, 15, or 20 years ago. However, identifying where the greatest benefits can be realized is a task for an engineer who can use building-modeling software to analyze multiple energy-saving scenarios.

There were some easy wins at UNCW, such as outdated boilers, but to achieve the mandated reduction in energy consumption, engineers had to look beyond the mechanical room.

One of the first things that the assessment revealed was that the university’s central plant was under-utilized by nearly 50%: the expense of owning and operating the boilers and chillers in the central plant was being duplicated in the

degrees of heat to a room. With new intelligent lighting controls and sensors, engineers can program systems in buildings such as the university’s Randall Library to turn off fixtures in unoccupied areas instead of letting them burn 24/7. The result: lower energy demand and longer-lasting bulbs and fixtures, which provides additional operational savings.

Another improvement that is unique to UNCW, among the state’s university PC projects, is the installation of solar tubes as an alternative lighting source. The application reduces the need for traditional lighting during daylight hours with no significant heat gain in a room.

mechanical rooms in other campus buildings.

Connecting four more buildings to the central plant allowed Brady to eliminate the redundant heating and cooling units, as well as push the central-plant units to peak loading and efficiency.

“The central plant was loafing along unloaded and running at an inefficient operating point,” said Gasper. “The university had made an investment in the central plant but was unable to realize all the benefits of this investment.”

Big savings were available outside the mechanical rooms too. Adding programmable, computerized controls and monitoring that connects the campus allows the university staff to control comfort while simultaneously eliminating waste in unused areas of the buildings. The control system also improves the ability to detect and correct problems in real time.

In addition, variable-speed drives were installed on a number of pumps and air handlers, allowing them to operate at reduced speeds and providing very substantial horsepower savings and prolonging the lives of the devices, thanks to reduced rotational speeds and pressures.

An often-overlooked contributor to thermal load and overall energy consumption is lighting.

Since virtually all of the power consumed by lights eventually is transformed into heat, even high-efficiency lighting can contribute several 32

Major math In total, the improvements to UNCW came with a $4.5-million price tag. A regional bank provided the funding through a 20-year, low-interest loan.

The performance contract guarantees a minimum of $336,566 in utility and operational savings with a 2.7% annual escalation in savings over the life of the contract—totaling more than $9 million. The first reconciliation audit is due in July of 2012.

If performance at UNCW matches other Brady projects, the results will meet or exceed projections. Brady engineers also handled the energy-efficiency project at North Carolina Museum of Art, Raleigh, which was the first in the state to be funded with a PC. Now in its fifth year, the museum has exceeded projected savings by more than $2.8 million. The Univ. of North Carolina Greensboro, the first university PC in the state and another Brady project, is in its fourth year of savings. The first two years of reconciliation audits show annual energy and operational savings in excess of $1.2 million.

Every facet in business seems to demand doing more with less, including the business of running an institution of higher learning. The public is resistant to tuition increases that would affect tight household budgets. State governments are cash strapped, calling for across-the-board cuts in spending, to the point of mandating percentages in specific areas of operations.

However, PC-based facility improvements provide one shining light for meeting such mandates. They provide cash-neutral projects that help keep university facilities state-of-the-art, promote sustainability and efficiency, and even provide jobs for contractors in the construction industry. By the end of 2012, Brady projects that it will be responsible for almost $70 million in PC-financed facility upgrades across the state.

This type of public-private cooperation may be a key to a more sustainable economy.
